libLab SDK Generation Platform

An automated SDK generation platform that raised a 42 million dollar Series A from Insight Partners with backing from StepStone Group, now part of Postman following acquisition, serving enterprise customers including T-Mobile, Deel, Rapyd, MagicBell, Celitech, and Doppler. The platform accepts OpenAPI, Swagger, and Postman collection specifications and generates idiomatic, fully customizable client SDKs for C#, TypeScript, PHP, Java, Go, and Python, with built-in language best practices for authentication, error handling, retry logic, and pagination. Customer outcomes include MagicBell achieving a 29 percent increase in developer productivity with superior code quality compared to alternative generators, Celitech reducing development cost by 50 percent while significantly reducing integration time for end users, and Doppler seeing a 178 percent increase in developer adoption after publishing generated SDKs. A declarative liblab.config file specifies target languages, package managers, and customizations, with CI/CD integration that automatically regenerates and publishes SDKs to npm, PyPI, NuGet, Packagist, Maven, and Go modules whenever the API specification changes. Beyond SDKs, the toolkit generates API documentation with embedded SDK code snippets, Terraform providers for infrastructure-as-code management, and MCP servers that transform API endpoints into AI-accessible interfaces for natural language interactions. SOC 2 compliant with a public SDK hub offering free, pre-built SDKs for popular APIs. Recognized as Product of the Day number 2 on Product Hunt.
