Get migration PRs before vendor APIs break your code.
We watch your dependencies' changelogs, find the lines in your repo that use deprecated calls, and open a pull request with the suggested fix — every PR includes a diff, the reasoning, and a link to the canonical doc.
We'll email you when your account is ready. No spam. See pricing →
How it works
Install the GitHub App
Grant read access to repos that use the dependencies you care about. We only ever open pull requests — never push to your default branch.
We watch upstream changes
When a vendor publishes a deprecation, breaking change, or new API version, we ingest it within hours and identify the exact lines in your code that are affected.
Review a PR, merge or close
A pull request lands in your repo with the proposed diff, the LLM's reasoning, and a link to the canonical changelog entry. You stay in control of every merge.
Why us
Built by a team that lives inside the changelog firehose.
We use AST analysis (not regex) to find affected code, so we catch aliased imports, destructured calls, and wrapper functions. We never push to your default branch and request only the minimum permissions needed to open pull requests.
