Replit just announced that its integrations catalog has crossed 450 connectors, making it what the company calls the largest integration library in AI. The pitch is simple: describe what you want to build, and Replit Agent handles the wiring. No OAuth credential juggling, no SDK setup, no context switching.
From 20 to 450 in under a year
The speed of this expansion is worth pausing on. In 2025, Replit moved from a handful of services to 30+ connectors by October, then expanded to 160+ after acquiring OpenInt. That acquisition -- Replit's first-ever, announced September 30, 2025 -- brought in OpenInt, a Y Combinator Winter 2023 company that had become a leading integration platform (iPaaS) built specifically for code generation. Now, less than nine months later, the catalog has nearly tripled again to 450+.
Connectors is now powering over 100,000 active repl connections, with over 450,000 created to date. That's not just a catalog number -- it reflects real usage across a platform that now has more than 50 million users globally, not all of them engineers -- product managers, operators, founders, students, and small business owners are increasingly shipping production software on it.
How the integrations actually work
There are three distinct integration types in Replit's system, and understanding the difference matters for how you use them:
- Connectors -- First-party integrations Replit supports directly. Sign in once, and Agent can read and write to these services from chat -- pull data, create records, send messages -- and build with them across all your apps.
- External integrations -- Trusted third-party services you build with. Ask Agent to set them up and you provide API keys, which are stored securely in your app's Secrets.
