Opslane

Opslane is an open-source error tracker designed to identify and fix user-facing bugs by combining error tracking with session recording. It captures errors, console logs, network requests, and session recordings through a browser SDK, then ranks issues by user impact and investigates them automatically. The system detects both exceptions and silent failures like unresponsive buttons or abandoned forms.

Opslane is built for developers and teams using coding agents. It includes an MCP server so agents can pull digests and fix bugs from the terminal. The worker component investigates issues in a sandbox, verifies fixes against your build and tests, and opens pull requests only when confident in the solution. The entire stack runs on Docker Compose with Postgres and MinIO.
