Hyperset opens a private beta that lets coding agents cite what your app actually did at runtime

Announced Oct 26, Hyperset attaches to local Node.js, Python and Go apps through their native debuggers with no SDK, records arguments, return values and exceptions into a local ring buffer, and lets its own agent or Claude Code, Codex, OpenCode and Pi cite those records while debugging (Cursor isn't supported yet). Access is limited to accepted testers, with a seven-day free trial and automatic change verification still in development.
