Modernize any repo without a dedicated migration sprint
Helix reads your codebase, proposes a step-by-step migration plan, and opens pull requests with passing tests.
Framework upgrades, dependency rewrites, and language migrations usually sit in the backlog for quarters. Helix checks out the repo, runs the test suite, applies the change in an isolated sandbox, and keeps iterating until CI is green.
You review the diff and approve — or ask Helix to try a different approach. Every change is a normal pull request your team already knows how to review.

- Run in the background while your team ships current work
Works with
- Next.js
- React
- Node
- Python
- Rails
- TypeScript
Why Helix
- No context-switching for senior engineers during a long migration
- Every change is verified in a sandbox before it becomes a PR
- Retries with alternative strategies when tests fail
- Your existing CI/CD and code-review process stays unchanged
