Software should keep up with the APIs it depends on.

Every product is built on third-party APIs, and every one of them changes. Today, keeping up means engineers reading changelogs, hunting for call sites, and rewriting the same code across service after service.

Why we're building Versyka

Coding agents can now change code reliably when they have a precise task and a way to check their work. An API change is exactly that kind of task: the vendor knows what changed, and your tests know whether the new code works. Versyka connects the two, so API changes can be applied, not just announced.

We support TypeScript, JavaScript, Python, Go, Java and Kotlin, on GitHub and GitLab, with a simple rule: if a change breaks your tests, we don't open a pull request. How it works.

Work with us

We're looking for design partners: engineering teams with a stuck migration, and API providers with a breaking change to ship.
