Opslane

Opslane finds the bugs, fixes them, and opens the PR.

Visit Opslane

Opslane is an open-source bug-finding and fix-generation tool for web applications. It records user sessions and captures errors, then identifies the issues that affect real users, including problems that do not crash the app but cause users to abandon tasks. It reproduces the bug, writes a fix, and opens a pull request for review and merge.

The platform supports Next.js, Nuxt, React, Vue, and vanilla JavaScript, with GitHub repositories. It includes session replay, error capture, a daily digest, and MCP-based coding agent integration. Sensitive inputs are masked by default, and recordings are scrubbed before access. Default retention is 30 days. Opslane can be self-hosted via Docker Compose with Postgres and Minio.

Opslane is free to start, with the first pull request expected the following day. It is open source and available on GitHub.
