Your AI can't fix
what it can't see

snapfail captures the full browser error context — stack trace, console output, network requests, user actions — and packages it so your AI editor can diagnose and fix bugs without you having to understand a single line of code.

Works with Cursor, Claude Code, and any AI that can run a terminal.

terminal
$ snapfail explain ba7b555c
## Error Report

Three steps, then it runs itself

1
One command setup
Run snapfail init in your project. It detects your framework, injects the SDK, and configures everything automatically.
$ snapfail init
2
Errors captured automatically
When a user hits an error, the SDK captures the full context before it disappears — stack trace resolved to source, console output, network requests, and the user's action sequence.
stack trace source maps console network replay timeline device info
3
Ask your AI to fix it
Run snapfail explain <id> from your AI editor's terminal. The output is structured evidence your AI can reason about directly — no copy-pasting, no explaining what happened.
$ snapfail explain ba7b555c

Not another error monitor

Error monitors show you a dashboard full of alerts and expect you to read a minified stack trace and figure out the cause yourself.

snapfail is different. The captured evidence isn't meant for you to look at — it's structured for an LLM to reason about. Every field, every entry, every timeline event is formatted to minimize tokens and maximize diagnostic signal.

Your AI editor gets the same context a senior engineer would have if they were sitting next to the user when the error happened.

error monitor
  • Dashboard to monitor
  • Alerts to triage
  • Stack trace to read
  • You figure out the fix
snapfail
  • Evidence package for your AI
  • One command to diagnose
  • Source-resolved stack
  • AI proposes the fix

Built for the real world

◈
Source maps
Stack frames resolved to your original source files and line numbers — even in production builds. Uploaded automatically at build time.
⊘
Noise filtering
Browser extension errors, bots, Safari injections, IE leftovers — all filtered before they reach your inbox. Suppression rules for anything else.
⊡
Replay timeline
The sequence of user actions before the crash — clicks, navigation, inputs — derived into a concise timeline your AI can follow.
◎
Privacy first
Scrubbed in the browser before it leaves the page. Auth headers, passwords, tokens, and card numbers never reach the server.
◇
User impact
See how many unique users hit each error — not just occurrence count. Prioritize what actually matters to real people.
⊞
Any framework
Native integrations for Astro, Next.js, and Vite. Or drop in a single <script> tag for anything else.

Stop debugging. Start fixing.

Set up in under two minutes. Works on your next deploy.
