What Faundr is for
When something breaks in your live app, you usually find out from an angry customer and then spend an hour digging through logs. Faundr catches the error the moment it happens, figures out the likely cause and hands it to Claude Code or Codex in the session you already use, so the fix starts right there.
How it plugs into your product
- 1Create a free Faundr account and link your project folder with the Faundr plugin.
- 2Turn on live-app errors: Faundr adds a small snippet to your browser and server code.
- 3Publish the app as usual; new errors show up on the dashboard grouped by cause.
- 4In your next Claude Code or Codex session, ask it to fix the open errors.
Does it fit your idea?
It fits if
- You build with Claude Code or Codex and want errors fixed in the same session, not read in another dashboard.
- Your app is small to mid-sized and 1,000 errors a month on the free plan covers the start.
- You don't want to learn a monitoring tool just to know what broke.
Look elsewhere if
- You need uptime alerts when the site goes down: use Better Stack.
- You need performance tracing or session replay: use Sentry.
- Your team doesn't use Claude Code or Codex.
What people only find out after building
Read this before you build on it. Each item links to the official page that says so.
Each project takes up to 3,000 errors an hour; past that, new ones are refused until the next hour, so an error loop in a bad release can hide others.
Official source: faundr.devIt doesn't watch whether your site is up; it only sees errors from pages and requests that actually ran.
