Sentry vs UptimeRobot

From $26 per month (Team plan, indicative)

From €9 per month (Solo, billed annually; €10 monthly)

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

One of the best free tiers in infrastructure tooling, and paid plans are still inexpensive: Solo €9, Team €35 and Scale €65 a month on annual billing. Solo buys the 60-second interval.

Free developer plan with a monthly error and replay allowance.

50 monitors at 5-minute intervals, free forever, with SSL and domain-expiry checks and one status page.

• 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.

• Free tier covers what most small projects actually need.
• Five-minute setup with no configuration to learn.
• Status pages included even on lower tiers.

• 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.

• No browser-based transaction monitoring — availability only.
• Basic alerting logic; expect some noise from transient failures.
• Limited reporting and no observability integration.

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

Side projects, small businesses and anyone who currently has no monitoring at all.
