Belay – See what keeps going wrong in your Claude Code and Codex sessions (getbelay.vercel.app)

Belay, a new tool for developers working with Claude Code and Codex, has been launched to streamline coding sessions by organizing and analyzing past projects stored locally on users' machines. By creating a timeline of coding sessions, Belay enables users to revisit previously completed tasks without starting new sessions from scratch. The tool identifies patterns in errors, such as failed typechecks, and prepares actionable insights for the next coding cycle, ensuring that lessons learned carry over and reduce time wasted on repeated mistakes. This is significant for the AI/ML community as it enhances the efficiency of AI-assisted coding by allowing developers to harness historical data to inform future actions. With a focus on maintaining user privacy—Belay performs all operations locally without uploading data to external servers—it supports a seamless workflow without disrupting existing agent actions. Belay's ability to issue proposed rules and verification commands based on past experiences not only increases productivity but also elevates the role of AI in coding by acting as a sophisticated feedback system, promising a transformative impact on software development practices.
