Polylane
A.I. agents that find issues in your app and open pull requests with fixes
Polylane is a tool for software teams. The company says it makes your software self-operating. A.I. agents learn what you run, watch your logs, metrics and traces, and raise an issue when something drifts from normal. The pages show Coreplane Labs in the footer.
When something breaks, Polylane looks across your code, your deploys and your data to show what broke and why. It can then write a fix and open a pull request, which goes through your normal review and tests. To start, you run one command on macOS or Linux, which installs the command-line tool, connects your coding agents and creates your account. There's a free plan, and paid plans add more usage. It's built for developers and on-call teams, so beginners may find it technical.

Our take (opinion)
Best for
- 🛠️ Software teams who are tired of being on-call for production problems
- Developers who want fixes delivered as pull requests they can review
- Teams already using tools like GitHub, Slack or AWS
Watch out for
- Built for engineering teams, so it may not suit non-developers
- Agent work uses a monthly credit pool, so heavy use may need a higher plan
- The Free plan is limited to 2 team members and 2 cloud accounts
