RuntimeVault
Freeze the exact moment your app failed. Replay it.
RuntimeVault 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. No more debugging from a bare stack trace. Free plan forever. How it works: 1. Install SDK (2 lines) 2. Error fires → snapshot captured 3. Run `rv replay snap_id` → local environment restored What makes it different from Sentry/LogRocket: we don't just show you what happened — we let you replay the exact state locally.
Hey PH! 👋
I built RuntimeVault because I was tired of reproducing bugs from stack traces alone.
The core idea: when an error fires, freeze the entire runtime state — variables, network requests, DOM, storage — and let developers (or AI agents) replay it locally.
It's like git for runtime. `rv replay` restores your app to the exact moment it broke.
Free plan, open source SDK, works with any MCP agent.
Would love feedback on the DX. What would make you actually use this?
Love the local replay angle, that is a real pain Sentry never solves. One thing that would make this way more useful for me though is letting the replay seed a Jest or Vitest test automatically so you can lock down a regression the second you find it.
The `rv replay snap_id` workflow is such a sharp move. Treating a runtime snapshot like a git checkout makes it obvious how to use it, and tying it into MCP means the agent already has the context it needs without me explaining anything.
one thing that would make this even more useful for our team: the ability to redact sensitive fields before the snapshot leaves the browser. stuff like auth tokens, user emails, and form inputs can end up in captured state, and right now it looks like everything goes to the AI agent as-is. a simple allowlist or regex mask in the SDK config would let us ship this to production without worrying about leaking customer data through the replay.

Who hunted RuntimeVault?
RuntimeVault was hunted by Giovanne Sartor. A “hunter” on Product Hunt is the community member who submits a product to the platform — uploading the images, the link, and tagging the makers behind it.
