Errors and monitoring
Faundr vs Sentry vs Better Stack
Faundr, Sentry, Better Stack side by side: price, free tier, who each one fits and when to skip it.
| Item | |||
|---|---|---|---|
| What it does | Catches errors from your live app and hands each one to Claude Code with the cause and the fix, inside Faundr. | Error and performance monitoring that shows the stack trace, the release and the user behind each crash. | Uptime monitoring, status pages, on-call, logs and error tracking in one place. |
| Best for | Founders building with Claude Code or Codex who want errors fixed in the same session, not read in another dashboard. | SaaS built with AI-generated code that needs to know which deploy broke checkout before the customer complains on WhatsApp. | Small SaaS that wants to be alerted when the site goes down and show customers a public status page, on the free plan. |
| Skip it if | You need uptime checks, performance tracing or session replay: use Better Stack or Sentry for those. | You only need to know whether the site is up and paged on call; Sentry's free plan has just one uptime monitor. | You want phone or Slack on-call alerts for the whole team, since each responder costs $29 to $34 a month in dollars. |
| Setup | A little code. About 10 minutes; the plugin adds the snippet for you. | A little code. About 30 minutes with the wizard; an extra hour or two to get source maps right in the deploy. | No code. About 10 minutes for monitors and the status page; logs take an extra hour. |
| Price | Free; Duo $29/month with 25,000 errors | Team from $26/month billed yearly ($29 monthly) | From $29 per responder/month billed yearly ($34 monthly) |
| What it costs in practice | A SaaS with a few hundred users usually stays under 1,000 errors a month: $0. Past that, Duo is $29/month for 25,000. | A SaaS on Team ($29/month, 50K errors) that has a bad month with 80K errors pays 30K × $0.0003625 ≈ $11 extra, if a pay-as-you-go budget is set. Adding 2,000 replays costs about 1,950 × $0.00375 ≈ $7. Total around $47/month. Rough estimate. | Two founders who want phone alerts at night: 2 responders × $34 = $68/month, or $58/month paid yearly. With email and Slack only, the same setup with 10 monitors and a status page costs $0. Rough estimate. |
| Free plan | 1,000 live-app errors a month on the Free plan. | Developer: 1 user, 5K errors, 5M spans, 50 replays, 1 uptime and 1 cron monitor. | 10 monitors, 1 status page, 100K exceptions/month and 3GB of logs kept for 3 days. |
| Free tier | 1,000 errors/month | 1 user, 5K errors/month | 10 monitors, 100K errors/month |
| First paid plan | Duo $29/month (25,000 errors) | Team: $29/month (50K errors) | $34/responder/month ($29 yearly) |
| What it covers | Browser and server errors, fix inside Claude Code | Errors, tracing, replay, logs, uptime, cron | Uptime, status page, on-call, logs, errors |
