Repurpo

Repurpo is a Next.js 15 SaaS app that turns one source into platform-ready content.

What the app does

Repurpo takes one input source and repurposes it into output tailored for:

• LinkedIn
• X / Twitter
• Instagram
• Reddit
• Newsletter

Input modes:

• article / web URL
• YouTube URL
• raw pasted text

The app also includes:

• Supabase auth
• private per-user history
• admin tools
• billing via Dodo Payments
• image generation via Cloudflare AI
• extraction cache and generation cache via Redis / Supabase fallback
• generation rate limits and slot controls

Latest generation flow

1. The user signs in with Supabase Auth.
2. The dashboard accepts a URL, YouTube link, or raw text.
3. The app extracts or sanitizes the source.
4. The user picks platforms and can set tone / length per platform.
5. The app checks cache per platform, not as one all-or-nothing bundle.
6. Gemini generates only the missing platform outputs.
7. Results are streamed to the UI through SSE.
8. The generation is saved in Supabase and cached in Redis.
9. The user can regenerate and bypass cache when needed.

Current architecture

• Frontend: Next.js App Router + React 19 + Tailwind CSS
• Auth / DB: Supabase SSR + PostgreSQL + RLS
• AI text: Google Gemini
• AI images: Cloudflare AI
• Cache: Upstash Redis
• Payments: Dodo Payments
• Validation: Zod
• Security: middleware, headers, blocked-user redirects, rate limits

Important env vars

See .env.example for the full list. The main ones are:

• NEXT_PUBLIC_SUPABASE_URL
• NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY
• SUPABASE_SERVICE_ROLE_KEY
• GEMINI_API_KEY
• UPSTASH_REDIS_REST_URL
• UPSTASH_REDIS_REST_TOKEN
• CLOUDFLARE_ACCOUNT_ID
• CLOUDFLARE_API_TOKEN
• DODO_*
• TURNSTILE_SECRET_KEY
• NEXT_PUBLIC_TURNSTILE_SITE_KEY

Key folders

• app/ — routes, pages, API routes, server actions
• components/ — reusable UI
• lib/ — auth, cache, Gemini, billing, security, utilities
• supabase/ — schema and SQL migrations
• public/ — assets and public static files

Important notes

• Files in the project root are not directly served by Vercel.
• To open a file in the browser, place it in public/.
• That is why public/REPURPO_STRUCTURE.md exists.
• public/privacy-policy.html is the browser-served privacy policy file.

Main routes

• / homepage
• /login
• /signup
• /forgot-password
• /reset-password
• /dashboard
• /history
• /history/[id]
• /profile
• /pricing
• /admin

Database and cache summary

• profiles stores user status, role, tier, billing, and block state.
• generations stores generation history.
• drafts stores autosaved dashboard state.
• content_extraction_cache stores article / transcript extraction.
• generation_slots and generation_rate_limits control concurrency and abuse.
• user_logs stores audit events.
• billing_webhook_events prevents duplicate webhook handling.

What changed recently

• per-platform tone and length controls
• partial cache reuse per platform
• regenerate bypasses cache
• Instagram and newsletter do not use “Open in app”
• dashboard and generation flow are being cleaned up for stricter type safety
