+# Dewe.Dev — Accounts, File Storage & Pro Features Plan
+
+**Created:** February 18, 2026
+
+---
+
+## Executive Summary
+
+Add user accounts and cloud file storage to dewe.dev without changing the existing UX. Visitors and logged-in users use the exact same tools. The only additions: a login/account page, save/load buttons per tool, and server-side URL fetching for Pro users. Backend powered by self-hosted Supabase on Coolify.
+
+---
+
+## Guiding Principles
+
+1. **Zero UX disruption** — Tools work identically for everyone. Auth is invisible until the user wants it.
+2. **Frontend stays king** — All processing remains client-side. The backend is only for storage, auth, and proxy.
+3. **Progressive enhancement** — Each feature layer (auth → storage → proxy → billing) can ship independently.
+4. **Privacy preserved** — File content is user-owned. RLS enforces isolation. No analytics on file content.
+
+---
+

+
+## Phase 1: Supabase Setup on Coolify
+
+**Goal:** Get the backend running and verified before writing any frontend code.
+
+### 1.1 Deploy Supabase on Coolify
+
+Coolify supports Supabase as a one-click service (or via Docker Compose).
+
+**Resource Requirements:**
+| Resource | Minimum | Recommended |
+|----------|---------|-------------|
+| CPU | 2 cores | 4 cores |
+| RAM | 4 GB | 8 GB |
+| Disk | 20 GB SSD | 50 GB SSD |
+
+**Services that spin up:**
+- PostgreSQL (database)
+- GoTrue (auth)
+- PostgREST (auto-generated REST API)
+- Realtime (websockets — can disable if unused)
+- Storage API (file storage — optional for this use case)
+- Edge Runtime (Deno functions)
+- Studio (admin dashboard)
+- Kong/Envoy (API gateway)
+
+**Critical Coolify configuration:**
+- Map persistent volumes for PostgreSQL data directory — data survives container restarts
+- Set up SSL via Coolify's built-in Let's Encrypt
+- Configure `SITE_URL` to `https://dewe.dev`
+- Set `ADDITIONAL_REDIRECT_URLS` for localhost dev
+- Expose only the API gateway port (default 8000) and Studio port (default 3000)
+
+### 1.2 Database Schema
+
+```sql
+-- Profiles table (extends auth.users)
+create table profiles (
+  id uuid primary key references auth.users on delete cascade,
+  display_name text,
+  tier text not null default 'free' check (tier in ('free', 'pro')),
+  tier_expires_at timestamptz,
+  storage_used_bytes bigint default 0,
+  created_at timestamptz default now(),
+  updated_at timestamptz default now()
+);
+
+-- Auto-create profile on signup
+create or replace function handle_new_user()
+returns trigger as $$
+begin
+  insert into profiles (id, display_name)
+  values (new.id, coalesce(new.raw_user_meta_data->>'display_name', split_part(new.email, '@', 1)));
+  return new;
+end;
+$$ language plpgsql security definer;
+
+create trigger on_auth_user_created
+  after insert on auth.users
+  for each row execute function handle_new_user();
+
+-- Sync tier to JWT custom claims (app_metadata)
+create or replace function sync_tier_to_claims()
+returns trigger as $$
+begin
+  update auth.users
+  set raw_app_meta_data = raw_app_meta_data || jsonb_build_object('tier', new.tier)
+  where id = new.id;
+  return new;
+end;
+$$ language plpgsql security definer;
+
+create trigger on_tier_change
+  after update of tier on profiles
+  for each row execute function sync_tier_to_claims();
+
+-- User files table
+create table user_files (
+  id uuid primary key default gen_random_uuid(),
+  user_id uuid references auth.users on delete cascade not null,
+  tool_type text not null,  -- 'markdown', 'invoice', 'object', 'table', 'beautifier'
+  name text not null,
+  content jsonb not null,   -- The actual file data
+  metadata jsonb default '{}',  -- Optional: last export format, preview text, etc.
+  size_bytes integer generated always as (octet_length(content::text)) stored,
+  created_at timestamptz default now(),
+  updated_at timestamptz default now()
+);
+
+-- Indexes
+create index idx_user_files_user_tool on user_files(user_id, tool_type);
+create index idx_user_files_updated on user_files(user_id, updated_at desc);
+
+-- Proxy usage logging (for rate limiting & analytics)
+create table proxy_logs (
+  id bigserial primary key,
+  user_id uuid references auth.users not null,
+  target_url text not null,
+  method text not null,
+  status_code integer,
+  response_size integer,
+  duration_ms integer,
+  created_at timestamptz default now()
+);
+
+create index idx_proxy_logs_user_time on proxy_logs(user_id, created_at desc);
+```
+
+### 1.3 Row Level Security (RLS)
+
+```sql
+-- Profiles: users can read/update only their own
+alter table profiles enable row level security;
+
+create policy "Users can view own profile"
+  on profiles for select using (auth.uid() = id);
+
+create policy "Users can update own profile"
+  on profiles for update using (auth.uid() = id);
+
+-- User files: full CRUD, own files only
+alter table user_files enable row level security;
+
+create policy "Users can view own files"
+  on user_files for select using (auth.uid() = user_id);
+
+create policy "Users can insert own files"
+  on user_files for insert with check (auth.uid() = user_id);
+
+create policy "Users can update own files"
+  on user_files for update using (auth.uid() = user_id);
+
+create policy "Users can delete own files"
+  on user_files for delete using (auth.uid() = user_id);
+
+-- Proxy logs: users can view own logs
+alter table proxy_logs enable row level security;
+
+create policy "Users can view own proxy logs"
+  on proxy_logs for select using (auth.uid() = user_id);
+```
+
+### 1.4 Storage Limits
+
+| Tier | Max files | Max file size | Total storage |
+|------|-----------|---------------|---------------|
+| Free | 20 | 256 KB | 5 MB |
+| Pro | Unlimited | 2 MB | 100 MB |
+
+Enforced via database function:
+
+```sql
+create or replace function check_storage_limit()
+returns trigger as $$
+declare
+  current_count integer;
+  current_size bigint;
+  user_tier text;
+  max_count integer;
+  max_total bigint;
+begin
+  select tier into user_tier from profiles where id = new.user_id;
+
+  if user_tier = 'free' then
+    max_count := 20;
+    max_total := 5 * 1024 * 1024;  -- 5 MB
+  else
+    max_count := 10000;
+    max_total := 100 * 1024 * 1024;  -- 100 MB
+  end if;
+
+  select count(*), coalesce(sum(size_bytes), 0)
+  into current_count, current_size
+  from user_files where user_id = new.user_id;
+
+  if current_count >= max_count then
+    raise exception 'File limit reached (% files for % tier)', max_count, user_tier;
+  end if;
+
+  if current_size + octet_length(new.content::text) > max_total then
+    raise exception 'Storage limit reached (% bytes for % tier)', max_total, user_tier;
+  end if;
+
+  return new;
+end;
+$$ language plpgsql;
+
+create trigger check_storage_before_insert
+  before insert on user_files
+  for each row execute function check_storage_limit();
+```
+
+### 1.5 Backups
+
+Self-hosted = you own backups. Set up immediately:
+
+```bash
+# Cron job on Coolify host (daily at 3 AM)
+0 3 * * * pg_dump -h localhost -U postgres -d postgres | gzip > /backups/dewe_$(date +\%Y\%m\%d).sql.gz
+
+# Retention: keep 30 days
+find /backups -name "dewe_*.sql.gz" -mtime +30 -delete
+```
+
+Optional: pipe to S3-compatible storage (MinIO on Coolify, or external).
+
+---
+
+## Phase 2: Auth Integration (Frontend)
+
+**Goal:** Add authentication without changing any existing tool UX.
+
+### 2.1 Auth Provider Setup
+
+```
+src/
+├── contexts/
+│   └── AuthContext.js        # Supabase auth state
+├── hooks/
+│   ├── useAuth.js            # Auth convenience hook
+│   └── useUserFiles.js       # File CRUD hook
+├── components/
+│   ├── AuthModal.js          # Login/signup modal (not a page redirect)
+│   ├── UserMenu.js           # Header avatar/dropdown
+│   └── SaveLoadBar.js        # Save/Load UI for tools
+├── pages/
+│   └── AccountPage.js        # /account - profile, files, settings
+└── lib/
+    └── supabase.js           # Supabase client init
+```
+
+### 2.2 "Ghost Auth" Pattern
+
+The core UX principle: **tools never change behavior based on auth state.**
+
+```
+┌──────────────────────────────────────────────────┐
+│                  Tool Editor                     │
+│                                                  │
+│  Visitor sees:     │  Logged-in user sees:       │
+│  [Copy] [Download] │  [Copy] [Download] [Save]   │
+│                    │                     ↑        │
+│                    │              only addition   │
+└──────────────────────────────────────────────────┘
+```
+
+**Rules:**
+- No redirects to login page from tools. Ever.
+- Clicking "Save" when not logged in → opens AuthModal (login/signup) as overlay
+- Current editor state is preserved in React state during login
+- After successful auth, the save action proceeds automatically
+- "Load" button appears in the tool's input section (alongside Create/URL/Paste/Open tabs)
+
+### 2.3 Auth Methods
+
+| Method | Priority | Notes |
+|--------|----------|-------|
+| Email + Password | P0 | Core auth, must have |
+| GitHub OAuth | P1 | Target audience is developers |
+| Google OAuth | P2 | Broad reach, nice to have |
+| Magic Link (Email) | P2 | Passwordless option |
+
+### 2.4 Header Changes
+
+```
+Before (visitor):
+┌─────────────────────────────────────────────────┐
+│ [Logo]                    [Tools ▾] [🌙] [☰]   │
+└─────────────────────────────────────────────────┘
+
+After (visitor):
+┌─────────────────────────────────────────────────┐
+│ [Logo]              [Tools ▾] [🌙] [Sign In] [☰]│
+└─────────────────────────────────────────────────┘
+
+After (logged in):
+┌─────────────────────────────────────────────────┐
+│ [Logo]              [Tools ▾] [🌙] [Avatar ▾] [☰]│
+└─────────────────────────────────────────────────┘
+
+Avatar dropdown:
+  ├── Account & Files
+  ├── ─────────────
+  └── Sign Out
+```
+
+Minimal. No dashboard. The "Account & Files" link goes to `/account`.
+
+---
+
+## Phase 3: File Save/Load per Tool
+
+**Goal:** Each editor tool gets save/load capability for logged-in users.
+
+### 3.1 Which Tools Support Save/Load
+
+| Tool | Save Content | Content Format | Priority |
+|------|-------------|----------------|----------|
+| Markdown Editor | MD source text | `{ source: string }` | P0 |
+| Invoice Editor | Invoice data | `{ invoice: {...}, template: string }` | P0 |
+| Object Editor | JSON/PHP data | `{ input: string, format: string }` | P1 |
+| Table Editor | Table data | `{ headers: [...], rows: [...] }` | P1 |
+| Beautifier | Code input | `{ code: string, language: string }` | P2 |
+| Diff Tool | Both texts | `{ left: string, right: string }` | P2 |
+
+URL Encoder, Base64, and Text Length are **stateless tools** — no save/load needed.
+
+### 3.2 Save/Load UX per Tool
+
+**Save flow:**
+1. User works in editor as normal
+2. Clicks "Save" → if not logged in, AuthModal opens first
+3. Save dialog: enter file name (pre-filled with smart default)
+4. Saves to `user_files` via Supabase SDK
+5. Toast: "Saved to your account"
+
+**Load flow (new input tab):**
+1. Tool input section gets a 5th tab: `[Create] [URL] [Paste] [Open] [My Files]`
+2. "My Files" tab shows a list of saved files for this tool type
+3. Each entry: name, date, size, [Load] [Delete] buttons
+4. Loading replaces current editor content (with unsaved changes warning)
+
+**Smart defaults for file names:**
+- Markdown: first heading or "Untitled Document"
+- Invoice: "Invoice #{number} - {client_name}"
+- Table: "Table - {row_count} rows"
+- Object: "Object - {key_count} keys"
+
+### 3.3 `useUserFiles` Hook API
+
+```javascript
+const {
+  files,          // File[] for current tool_type
+  loading,        // boolean
+  saving,         // boolean
+  error,          // string | null
+  saveFile,       // (name, content, metadata?) => Promise<File>
+  updateFile,     // (id, content, metadata?) => Promise<File>
+  deleteFile,     // (id) => Promise<void>
+  loadFiles,      // () => Promise<void> (refresh)
+  storageUsed,    // { count, bytes, limit }
+} = useUserFiles('markdown');
+```
+
+---
+
+## Phase 4: Pro Proxy (Server-Side URL Fetch)
+
+**Goal:** Pro users bypass CORS with a server-side proxy via Supabase Edge Function.
+
+### 4.1 How It Works
+
+```
+Free user:                          Pro user:
+Browser → Target API                Browser → Edge Function → Target API
+         ↓                                    ↓
+    CORS blocked ❌                      No CORS ✅
+```
+
+### 4.2 Edge Function: `proxy-fetch`
+
+```typescript
+// supabase/functions/proxy-fetch/index.ts
+import { serve } from "https://deno.land/std/http/server.ts";
+import { createClient } from "https://esm.sh/@supabase/supabase-js";
+
+const BLOCKED_HOSTS = [
+  /^localhost$/i,
+  /^127\./,
+  /^10\./,
+  /^172\.(1[6-9]|2\d|3[01])\./,
+  /^192\.168\./,
+  /^0\./,
+  /^169\.254\./,        // link-local
+  /^::1$/,
+  /^fc00:/i, /^fe80:/i, // IPv6 private
+];
+
+serve(async (req) => {
+  // 1. Verify JWT and extract tier
+  const authHeader = req.headers.get("Authorization");
+  const supabase = createClient(SUPABASE_URL, SUPABASE_ANON_KEY, {
+    global: { headers: { Authorization: authHeader } }
+  });
+  const { data: { user }, error } = await supabase.auth.getUser();
+
+  if (!user || user.app_metadata?.tier !== "pro") {
+    return new Response(JSON.stringify({ error: "Pro subscription required" }), {
+      status: 403
+    });
+  }
+
+  // 2. Parse request
+  const { url, method, headers, body } = await req.json();
+
+  // 3. SSRF protection
+  const targetUrl = new URL(url);
+  if (BLOCKED_HOSTS.some(pattern => pattern.test(targetUrl.hostname))) {
+    return new Response(JSON.stringify({ error: "Blocked host" }), {
+      status: 400
+    });
+  }
+
+  // 4. Rate limiting check (50 req/min for Pro)
+  const { count } = await supabase
+    .from("proxy_logs")
+    .select("*", { count: "exact", head: true })
+    .eq("user_id", user.id)
+    .gte("created_at", new Date(Date.now() - 60000).toISOString());
+
+  if (count >= 50) {
+    return new Response(JSON.stringify({ error: "Rate limit exceeded (50/min)" }), {
+      status: 429
+    });
+  }
+
+  // 5. Forward request
+  const start = Date.now();
+  const response = await fetch(url, {
+    method: method || "GET",
+    headers: headers || {},
+    body: body ? JSON.stringify(body) : undefined,
+  });
+
+  const responseBody = await response.text();
+
+  // 6. Log usage
+  await supabase.from("proxy_logs").insert({
+    user_id: user.id,
+    target_url: url,
+    method: method || "GET",
+    status_code: response.status,
+    response_size: responseBody.length,
+    duration_ms: Date.now() - start,
+  });
+
+  // 7. Return response
+  return new Response(responseBody, {
+    status: response.status,
+    headers: {
+      "Content-Type": response.headers.get("Content-Type") || "application/json",
+      "Access-Control-Allow-Origin": "https://dewe.dev",
+    },
+  });
+});
+```
+
+### 4.3 Frontend Integration
+
+The existing `AdvancedURLFetch.js` component already has the full UI (method, headers, auth, body, presets). Currently hidden behind `{false && ...}`. Changes needed:
+
+1. **Free users:** Basic fetch (client-side, GET only, CORS-dependent) — current behavior
+2. **Pro users:** Toggle reveals advanced panel → requests go through Edge Function
+3. Update `features.js` to read tier from `user.app_metadata.tier` instead of static value
+4. Presets migration: move from localStorage to `user_files` with `tool_type: 'fetch_preset'`
+
+### 4.4 Security Measures
+
+| Threat | Mitigation |
+|--------|-----------|
+| SSRF (hitting internal services) | Block private IP ranges, resolve DNS before fetch |
+| Abuse (crypto mining, spam) | Rate limiting (50 req/min), response size cap (5 MB) |
+| Data exfiltration | Log all proxy requests, alert on anomalies |
+| JWT forgery | Verify JWT server-side on every request |
+| Cost attack (huge responses) | Stream with size limit, abort after 5 MB |
+
+---
+
+## Phase 5: Account Page
+
+**Goal:** Single page at `/account` for profile, files, and settings. Minimal.
+
+### 5.1 Page Layout
+
+```
+/account
+┌─────────────────────────────────────────────────┐

+
+### 5.2 "Open in Editor" Flow
+
+Clicking "Open in Editor" on a saved file:
+1. Navigates to the corresponding tool (e.g., `/markdown-editor`)
+2. Passes file ID via query param: `/markdown-editor?file=uuid`
+3. Tool detects `?file=` param → fetches from `user_files` → loads into editor
+4. Editor shows "Editing: {filename}" indicator
+5. Subsequent saves update the same file (not create new)
+
+---
+
+## Phase 6: localStorage Migration
+
+**Goal:** Seamlessly migrate existing localStorage data to cloud on first login.
+
+### 6.1 Migration Flow
+
+```
+User logs in for the first time
+         │
+         ▼
+  Check localStorage for known keys:
+  • urlFetchPresets
+  • (any other persisted tool data)
+         │
+         ▼
+  Found data? ──No──→ Done
+         │
+        Yes
+         │
+         ▼
+  Show toast: "We found saved data on this device.
+               Would you like to sync it to your account?"
+         │
+    ┌────┴────┐
+   Yes       No
+    │         │
+    ▼         ▼
+  Upload    Dismiss
+  to DB     (ask again
+  + clear    next login)
+  localStorage
+```
+
+### 6.2 Known localStorage Keys to Migrate
+
+| Key | Tool | Migration Target |
+|-----|------|-----------------|
+| `urlFetchPresets` | AdvancedURLFetch | `user_files` with `tool_type: 'fetch_preset'` |
+
+Currently this is the only localStorage key with user data. As tools add auto-save to localStorage (pre-auth), add those keys here.
+
+---
+
+## Phase 7: Pro Tier & Billing (Future)
+
+**Goal:** Monetize Pro features. Not in initial scope but schema is ready.
+
+### 7.1 Pro Features Summary
+
+| Feature | Free | Pro |
+|---------|------|-----|
+| All tools | Yes | Yes |
+| Copy & Download | Yes | Yes |
+| Save files | 20 files, 5 MB | Unlimited, 100 MB |
+| URL Fetch | Client-side (CORS-dependent) | Server-side proxy (any API) |
+| Fetch presets | localStorage only | Cloud-synced |
+| Advanced Fetch UI | Hidden | Full (methods, headers, auth, body) |
+| Ads | Yes | No |
+
+### 7.2 Pricing (Recommendation)
+
+**Subscription model** (recurring revenue > one-time):
+
+| Plan | Price | Billing |
+|------|-------|---------|
+| Monthly | $4.99/mo | Monthly |
+| Annual | $39.99/yr (~$3.33/mo) | Annual |
+
+**Why subscription over one-time:**
+- Server costs are ongoing (Coolify hosting, proxy bandwidth)
+- Aligns cost with value delivered
+- Predictable revenue
+
+**Payment provider:** Stripe (or Lemon Squeezy for simpler tax handling).
+
+### 7.3 Tier Enforcement Architecture
+
+```
+Client-side (fast):
+  user.app_metadata.tier → show/hide UI elements
+
+Server-side (secure):
+  JWT claims → Edge Function checks tier before processing
+  DB triggers → sync tier changes to JWT claims
+  Storage limits → DB trigger on insert
+```
+
+The `sync_tier_to_claims` trigger (Phase 1 schema) ensures that when you update `profiles.tier`, the JWT custom claim is updated. The user's next token refresh picks up the new tier automatically.
+
+---
+
+## Implementation Order
+
+```
+Phase 1: Supabase on Coolify          ░░░░░░░░  ~1 day
+  └─ Deploy, configure, run schema
+  └─ Verify connection from localhost
+
+Phase 2: Auth Integration             ░░░░░░░░░░░░  ~2 days
+  └─ supabase.js client setup
+  └─ AuthContext + useAuth hook
+  └─ AuthModal (login/signup overlay)
+  └─ Header UserMenu
+  └─ /account page (basic)
+
+Phase 3: File Save/Load               ░░░░░░░░░░░░░░░░  ~3 days
+  └─ useUserFiles hook
+  └─ SaveLoadBar component
+  └─ "My Files" tab in each tool
+  └─ Account page file manager
+  └─ Markdown Editor integration (first)
+  └─ Invoice Editor integration
+  └─ Remaining tools
+
+Phase 4: Pro Proxy                    ░░░░░░░░░░░░  ~2 days
+  └─ Edge Function deployment
+  └─ SSRF protection
+  └─ Rate limiting
+  └─ AdvancedURLFetch rewire
+  └─ Feature flags from JWT
+
+Phase 5: localStorage Migration       ░░░░  ~0.5 day
+  └─ Detection + migration prompt
+
+Phase 6: Polish & Testing             ░░░░░░░░  ~1.5 days
+  └─ Error states, loading states
+  └─ Mobile responsive check
+  └─ Auth edge cases (expired session, etc.)
+
+Total estimate: ~10 days
+```
+
+---
+
+## Technical Decisions & Rationale
+
+### Why JSONB in Postgres (not Supabase Storage)?
+
+All saved content is text-based and < 2 MB. JSONB gives us:
+- Queryable content (search inside saved files later)
+- Indexable fields (filter by tool_type, sort by date)
+- Single table, single query — no separate file download step
+- Atomic operations (save file + update metadata in one transaction)
+- Simpler backup (one pg_dump gets everything)
+
+Supabase Storage (S3-compatible) would be better for binary files (images, PDFs > 10 MB). We don't have that use case.
+
+### Why Edge Functions (not a separate Node.js proxy)?
+
+- Already included in self-hosted Supabase — no extra deployment
+- Direct access to Supabase Auth (JWT verification built-in)
+- Deno runtime is secure by default (explicit permissions)
+- Scales with the Supabase instance
+- One less service to maintain on Coolify
+
+### Why Modal Login (not a /login page)?
+
+- User is mid-work in an editor when they hit "Save"
+- Redirecting to /login would lose their unsaved editor state
+- Modal keeps React state intact — after login, save proceeds immediately
+- Better conversion: lower friction = more signups
+
+### Why Custom Claims for Tier (not DB lookup per request)?
+
+- JWT claims are verified locally — zero network latency
+- Edge Function doesn't need a DB query to check tier
+- DB trigger keeps claims in sync automatically
+- Standard Supabase pattern, well-documented
+
+---
+
+## Risks & Mitigations
+
+| Risk | Impact | Mitigation |
+|------|--------|-----------|
+| Supabase self-hosted instability | High | Monitor with Coolify health checks, set up alerts, daily backups |
+| Proxy abuse (SSRF, scraping) | High | IP blocklist, rate limiting, URL validation, response size cap |
+| Storage costs grow | Medium | Enforce limits per tier, compress JSONB, monitor `storage_used_bytes` |
+| Auth session expired mid-edit | Medium | Silent token refresh, save to localStorage as fallback, retry on 401 |
+| Migration from localStorage fails | Low | Non-destructive: keep localStorage as fallback, retry option |
+| Coolify resource limits | Medium | Start with 4 GB RAM, monitor, scale vertically as needed |
+
+---
+
+## Open Questions
+
+1. **OAuth providers** — GitHub OAuth is ideal for dev audience. Worth adding Google too for broader reach? Both are easy with Supabase Auth.
+
+2. **File sharing** — Should saved files be shareable via public link? (e.g., share a markdown preview). Not in initial scope, but schema supports adding a `is_public` flag later.
+
+3. **Auto-save** — Should tools auto-save to cloud every N seconds for logged-in users? Or only manual save? Recommendation: manual save only (simpler, less backend load, user controls what gets saved).
+
+4. **Offline support** — If Supabase is down, tools still work (client-side). But save/load fails. Should we queue saves in localStorage and sync when back online?
+
+5. **Delete account** — GDPR requires account deletion. The `on delete cascade` in the schema handles this. Need a confirmation flow in the UI.
