Postman, the ubiquitous platform for API development, announced today it is acquiring liblab, a startup focused on automating the generation of Software Development Kits (SDKs). The move is a clear and aggressive play to expand beyond its stronghold with API producers and capture the other side of the equation: API consumers.
In a blog post announcing the deal, Postman CEO Abhinav Asthana framed the acquisition as the key to building a truly unified, end-to-end platform for the entire API lifecycle. For years, Postman has been the go-to tool for developers designing, testing, and documenting APIs. But once an API is published, the often-manual, error-prone work of creating and maintaining client libraries for developers to actually use that API begins. That’s where liblab comes in.
I'm excited to share that @LibLaber is joining @getpostman 🎉

From day one, our mission has been simple: build the future of connected software. By bringing liblab’s SDK generation engine into the Postman platform, we’ll close the loop on the API lifecycle for millions of… pic.twitter.com/Nq09jy9Cci
liblab has been building what it calls an "SDKs-as-a-service" platform. Its engine can take an API specification and automatically generate high-quality, idiomatic SDKs in multiple programming languages, complete with documentation that stays in sync with any changes. This is a significant pain point for any company that offers a public API. By acquiring this capability, Postman is betting it can eliminate a major source of friction for its massive user base.
From API producer to consumer
The strategic logic here is simple but powerful. As Asthana noted, "what Postman provides for API producers, liblab offers to API consumers." By integrating liblab's technology, Postman aims to close this loop. The vision is a seamless workflow where a developer can design an API in Postman, test its endpoints, and then, with a click, generate and publish polished SDKs for Java, Python, TypeScript, and every other major language.
This transforms Postman from a development and collaboration tool into a full-fledged distribution platform. The acquisition will bring liblab’s core engine directly into Postman, making it accessible to the platform's more than 40 million registered developers. The promise is that test suites, documentation, and the client SDKs themselves will all remain perfectly synchronized, a holy grail for teams struggling with API versioning and maintenance.
This move also positions Postman for a future increasingly dominated by AI. The announcement explicitly mentions accelerating customers' ability to build "AI-ready, agent-enabled APIs." As AI agents become more common, they will need to interact with software programmatically through well-defined APIs. Clean, reliable, and auto-generated SDKs are the perfect interface for these agents, lowering the barrier for AI to consume web services.
For now, existing liblab customers will see no change in their service. Postman says it will communicate its integration plans soon, but the long-term goal is clear: to make SDK generation a native, core feature of the Postman platform. This acquisition isn't just about adding a new feature; it's a fundamental expansion of what Postman is, aiming to solidify its position as the indispensable, central hub for the entire API economy.
