We built Swytchcode because we have lived the pain of supporting APIs at scale.
As developers, we have spent countless hours writing and updating docs, answering the same integration questions, and creating sample code for every new customer workflow. It’s important work, but it doesn’t move the product forward.
With Swytchcode, we asked, what if the API itself could describe and demonstrate how it works?
Upload an OpenAPI spec or an SDK, and our system automatically generates interactive documentation, live playgrounds, and AI-suggested workflows with no manual upkeep.
What’s new and unique:
1. SDK-first and spec-first: our system can ingest either an SDK or a static OpenAPI file.
2. Workflow and method code: Generate code for method and workflows in 15+ languages
3. Built-in testing: Testing API endpoints with real parameters.
4. MCP code generation: developers can query and generate code through Model Context Protocol, a first in this space.
5. Real workflow automation: we don’t just show endpoints; we assemble multi-step, ready-to-run flows.
We are most proud of how quickly our solution helps other developers. Teams that used to spend weeks creating docs can now publish a fully interactive experience in minutes. Early customers, including two YC startups, are already integrating it into their onboarding to cut support tickets and speed up adoption.
For us, this launch isn’t just a product release—it’s a way to give developers back the time we always wished we had.
