# Versyka

> When third-party APIs ship breaking changes, Versyka finds every affected call in your code, applies the migration, runs your tests, and opens a pull request.

Versyka is a service for engineering teams and API providers. When a third-party API or SDK (Stripe, OpenAI, AWS, Twilio and others) ships a breaking change, Versyka:

1. turns the vendor's changelog or migration guide into a migration rule,
2. finds every affected call site with ast-grep (deterministic structural search; the AI never chooses which files to edit),
3. has Claude rewrite only those call sites, inside a disposable sandbox,
4. runs the repository's own install, typecheck, build and tests before and after, with up to 3 attempts,
5. opens a pull request on a new branch only if the change causes no new failures. It never pushes to the default branch.

Languages: TypeScript, JavaScript, Python, Go, Java and Kotlin (npm, pnpm, yarn, bun, pip, uv, poetry, pipenv, Go modules, Maven, Gradle). GitHub and GitLab.
Monitoring: a daily scan finds known vulnerabilities (OSV.dev), grouped into package upgrades, API SDKs from 100+ vendors that fell behind, and AI model IDs (OpenAI, Anthropic, Google Gemini, Mistral, Cohere, and models on Amazon Bedrock and Groq; Azure and Together AI retirements are listed for reference) retired or retiring within 90 days. Package upgrades: version bumps go into one pull request per repository (unlimited on every plan); breaking upgrades are migrated like any other change. Weekly upgrades: every Monday, one tested pull request per repository with the minor and patch releases of the packages it uses, each explained from its release notes. Dependabot and Renovate pull requests get an impact comment (what the release changes and where the code uses it). Retiring AI models with a direct replacement are swapped for free (no AI, no migration pull request), prepared automatically.
Pull request commands on GitHub: @versyka rebase, @versyka explain, @versyka help (write access required).
Access: a GitHub App on repositories the customer selects, with read and write to contents and pull requests, and read-only checks, commit statuses, issues, metadata and email address.
Stage: pilot. Design partners use it free. Plans include migration pull requests (code rewrites) a month: Free (2), Starter $49/month (10), Team $249/month (60), Scale $749/month (200), API providers from $1,500/month (annual). Version upgrades (no code changes) are unlimited on every plan, under fair use. Every plan has the whole product (tested fix pull requests, daily scan, email and Slack alerts, weekly summary, pull request commands); Free and Starter are for the owner and 2 teammates; Team adds the whole team with no seat fees, Autopilot, automatic rebuilds, a pull request schedule and audit log export; Scale adds custom migrations for internal libraries, staged rollouts, a shared Slack channel and invoice billing.

## For coding agents

Versyka runs a public MCP server (Streamable HTTP, no sign-in, read-only) at https://www.versyka.com/api/mcp with tools to check dependency manifests, find retired AI model IDs in code, look up a model's retirement date and replacement, get the latest SDK version and read migration guides as Markdown. The model retirement list is also JSON at https://www.versyka.com/api/model-retirements and an iCalendar feed at https://www.versyka.com/model-retirements.ics.
