I’m Reli, founder of Integrate API. I’m a musician-turned-developer who built 20 Next.js applications in 8 months.
The Origin Story:
Every single project required the same APIs:
Stripe for payments → 8 hours to integrate properly
Clerk for authentication → 5 hours
Supabase for database → 4 hours
Email, AI, real-time → 10+ hours
By project #5, I was copying my own code between projects.
By project #12, those copies became refined templates.
By project #20, I packaged them into Integrate API.
What Integrate API Actually Is:
Let me be crystal clear: This is NOT an AI code generator.
It’s a collection of hand-crafted, production-tested templates that you copy into your Next.js project. Think “npm install” but for complete API integrations.
What You Get:
Sixteen Production-Ready Integration Templates:
Payments & Billing:
Stripe – Payment processing and checkout sessions, subscription management, webhook handlers with cryptographic signature verification, customer portal integration, invoice handling, type-safe throughout
Lemon Squeezy – Checkout creation and management, webhook handlers with signature verification, license key generation and management, subscription handling and renewals, customer portal integration, variant and pricing management
Authentication:
Clerk – Authentication with middleware configuration, protected routes and role-based access, sign-in/up pages with redirect handling, user management and metadata, organization support, webhook handlers for user events
Auth0 – User management and profiles, SSO integration (SAML, OAuth), protected routes with middleware, session handling and token refresh, role-based access control, multi-factor authentication setup
Email:
Resend – Email sending with React Email templates, transactional email handling, delivery tracking and analytics, template management, error handling and retry logic, bulk email support
SendGrid – Template helpers and management, bulk sending and list management, email analytics and tracking, domain verification setup, suppression list handling, webhook integration for events
Real-time Collaboration:
Liveblocks – Real-time collaboration setup, presence tracking and user awareness, collaborative cursors and selections, typing indicators, room management, undo/redo functionality, data persistence
Ably – Pub/Sub messaging patterns, presence detection and tracking, push notifications, channel history and replay, connection state management, token authentication
Database & Backend:
Supabase – Database client with auto-generated TypeScript types, real-time subscriptions with error handling, auth helpers for Next.js middleware, row-level security examples, query optimization patterns, connection pooling configuration
PlanetScale – Database branching workflow, deploy requests and schema changes, edge function integration, connection pooling, query insights and analytics, migration management
AI:
OpenAI – Streaming chat responses with proper error handling, embeddings generation for semantic search, function calling support, rate limiting and retry logic, token counting and cost tracking, response streaming to client
Anthropic Claude – Streaming responses with SSE, multiple model support (Sonnet, Opus), function calling and tool use, React components for chat UI, token management, error handling and retries
Analytics & Content:
PostHog – Event tracking and custom events, feature flags integration, session replay setup, user identification and properties, A/B testing support, analytics dashboard integration
Sanity – Content API client setup, real-time updates with listeners, image optimization with CDN, GROQ queries and filtering, portable text rendering, preview mode integration
File Storage & Search:
Uploadthing – React upload components, type-safe file handling, automatic image optimization, upload progress tracking, file type validation, CDN integration
Meilisearch – Search index configuration, typo tolerance and fuzzy matching, faceted search and filtering, instant search components, relevance tuning, highlighting and snippets
Each template includes:
✓ Full TypeScript implementation
✓ Webhook handlers with signature verification
✓ Error handling and validation
✓ Environment variable setup
✓ Comprehensive documentation
✓ Real production examples (not “hello world” demos)
✓ Next.js 14 App Router optimization
✓ Server and client component patterns
✓ Loading states and error boundaries
DevFinder Chrome Extension:
This might be my favorite feature. Press Cmd+Shift+F on any website and it visually highlights:
🔵 API endpoints (blue)
🟢 Webhooks (green)
🟣 API keys (purple)
🟠 Auth tokens (orange)
Click any highlighted element to copy it. Perfect for:
API research and evaluation
Finding webhook URLs in documentation
Competitive analysis
Debugging client integrations
How It’s Different:
Boilerplates: Complete app you customize down → Locked into their architecture
Integrate API: Modular templates you drop in → Your architecture, your control
AI Generators: Create custom code on-demand → Great for unique features
Integrate API: Pre-tested production code → Great for common integrations
Technical Stack:
Built with the same tools I’m selling templates for:
Next.js 14 (App Router)
TypeScript (strict mode)
Stripe (for payments – using our template!)
Clerk (for auth – using our template!)
Supabase (for database – using our template!)
Meta moment: Integrate API is built with Integrate API templates.
Who Should Use This:
✅ Experienced developers – Get instant scaffolding, remove boilerplate from your workflow
✅ Junior developers – Learn correct-by-default patterns, don’t worry about folder structures or auth flows
✅ Technical founders – Ship features instead of infrastructure
✅ Agencies – Standardize integrations across all client projects

What I’d Love Your Feedback On:
Which integrations should we prioritize next? Top requests so far:
WorkOS (enterprise SSO)
Loops (email marketing)
Twilio (SMS & voice)
Neon (serverless Postgres)
Google Gemini (AI)
Notion API (productivity)
Would you use the DevFinder extension as a standalone product, or is it mainly valuable as part of the bundle?
For agencies: What would make this more valuable for multi-client workflows?
