Errors and monitoring

Better Stack vs Sentry vs Faundr

Better Stack, Sentry, Faundr side by side: price, free tier, who each one fits and when to skip it.

Item	Better Stack	Sentry	Faundr
What it does	Uptime monitoring, status pages, on-call, logs and error tracking in one place.	Error and performance monitoring that shows the stack trace, the release and the user behind each crash.	Catches errors from your live app and hands each one to Claude Code with the cause and the fix, inside Faundr.
Best for	Small SaaS that wants to be alerted when the site goes down and show customers a public status page, on the free plan.	SaaS built with AI-generated code that needs to know which deploy broke checkout before the customer complains on WhatsApp.	Founders building with Claude Code or Codex who want errors fixed in the same session, not read in another dashboard.
Skip it if	You want phone or Slack on-call alerts for the whole team, since each responder costs $29 to $34 a month in dollars.	You only need to know whether the site is up and paged on call; Sentry's free plan has just one uptime monitor.	You need uptime checks, performance tracing or session replay: use Better Stack or Sentry for those.
Setup	No code. About 10 minutes for monitors and the status page; logs take an extra hour.	A little code. About 30 minutes with the wizard; an extra hour or two to get source maps right in the deploy.	A little code. About 10 minutes; the plugin adds the snippet for you.
Price	From $29 per responder/month billed yearly ($34 monthly)	Team from $26/month billed yearly ($29 monthly)	Free; Duo $29/month with 25,000 errors
What it costs in practice	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.	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.	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.
Free plan	10 monitors, 1 status page, 100K exceptions/month and 3GB of logs kept for 3 days.	Developer: 1 user, 5K errors, 5M spans, 50 replays, 1 uptime and 1 cron monitor.	1,000 live-app errors a month on the Free plan.
Free tier	10 monitors, 100K errors/month	1 user, 5K errors/month	1,000 errors/month
First paid plan	$34/responder/month ($29 yearly)	Team: $29/month (50K errors)	Duo $29/month (25,000 errors)
What it covers	Uptime, status page, on-call, logs, errors	Errors, tracing, replay, logs, uptime, cron	Browser and server errors, fix inside Claude Code
Open source	No: no	No: no	No: no
Before you build	Free monitors check every 3 minutes at best; 30-second checks are paid only. Phone call and SMS alerts aren't on the free plan; each person who gets them needs a responder seat at $34/month ($29 yearly). Past 10 monitors you pay for packs of 50 at $25/month, and each extra public status page costs $15/month.	Once your quota and pay-as-you-go budget run out, new errors are dropped and monitoring stops until the next billing cycle. Spike protection, which keeps one error loop from eating your whole month's quota, is set per project; check it's on for every project. The free Developer plan allows 1 user and 30 days of history; adding a cofounder means Team at $29/month. Session replays past the included 50 are billed on top, starting at $3.75 per 1,000.	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. It doesn't watch whether your site is up; it only sees errors from pages and requests that actually ran.
