Captures full runtime state the instant an error fires and replays it locally, feeding coding agents like Claude Code real debugging context instead of a bare stack trace.

What to know▼
How it works
Captures the full runtime state the instant an error fires — stack, variables, network, DOM — and hands it to Claude Code, Cursor, or any MCP-compatible agent; install a 2-line SDK, then run `rv replay snap_id` to restore the local environment.
What's different
Unlike Sentry or LogRocket, it doesn't just show you what happened — it lets you replay the exact state locally.
Pricing
Free plan forever.
Best for
Developers debugging with AI coding agents who are tired of working from a bare stack trace.
