Sentry vs Better Stack

Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Entry price

From $26 per month (Team plan, indicative)

Free tier

From $25 per month per additional 50 monitors ($21 on yearly billing)

Free tier

What drives the bill

The metric that actually scales your invoice.

Event-volume pricing. A noisy application can consume the quota quickly, so filtering matters.

There are no named tiers for uptime monitoring — you start from the free 10 monitors and add blocks of 50. Still substantially cheaper than assembling Pingdom, PagerDuty and Statuspage separately.

Free tier

Free developer plan with a monthly error and replay allowance.

10 monitors and heartbeats plus 1 status page, with Slack and email alerts.

Strengths

  • Release and commit attribution tells you which deploy introduced the error, and often who to ask.
  • Excellent SDK coverage across essentially every language and framework.
  • Self-hosting is genuinely supported for teams that need it.
  • Replaces three separate subscriptions with one at a lower total cost.
  • Excellent status pages and incident communication out of the box.
  • Fast check intervals even on modest plans.

Limitations

  • Event-based pricing punishes noisy applications until you invest in filtering.
  • The product has broadened a lot; some newer modules are shallower than the error core.
  • Self-hosting is resource-hungry.
  • Browser-based transaction monitoring is limited compared to Checkly or Datadog.
  • Log management is capable but not a full observability platform.
  • Younger vendor than the incumbents.

Best for

Essentially every engineering team — error tracking is the highest-value monitoring you can add first.

Small and mid-sized teams consolidating uptime, on-call and status pages.

All of these integrate with: GitHub, Slack, PagerDuty.
