Sentry vs Better Stack for error and uptime monitoring

Sooner or later something will break while you're asleep. Sentry is built around catching errors inside your code and showing you the exact line. Better Stack starts from the outside: it checks your site is up, alerts you when it isn't, and adds error tracking and logs on top. Plenty of people use one of each.

How we check

The answer

Both have free plans that are plenty for a side project. On a paid plan, Sentry Team is £21.72 a month (£19.47 billed yearly) and covers your whole team. Better Stack charges per person who gets the alerts: £25.46 a month per responder, or £21.72 billed yearly. If you mostly want to know the site's down, Better Stack's free plan may be all you need.

What does it cost to know when your app breaks?

Sentry

  • Shows the exact line, device and steps behind each error, with tracing to show what was slow. Paid plans don't charge per seat.

How we worked it out

  • Sentry Team $29 × 0.7489 = £21.72 (21.7181); billed yearly $26 × 0.7489 = £19.47 (19.4714).
  • Better Stack responder licence $34 × 0.7489 = £25.46 (25.4626); $29 × 0.7489 = £21.72 (21.7181). Better Stack's page shows both $34 and $29 per licence without saying which is which. We've read $29 as the yearly rate, because yearly billing is described as about two months free.
  • Figures are for one person. Sentry Team includes unlimited users; Better Stack charges per responder licence.
  • Excludes VAT and usage above each plan's allowance.
