Pingdom vs Sentry

From $18 per month (10 uptime checks, 1 advanced check, 50 SMS; $16.50 annual)

From $26 per month (Team plan, indicative)

Priced by a calculator rather than named tiers: 50 uptime checks run about $78/month and 100 about $149, so the per-check rate falls slowly with volume. Transaction checks and Real User Monitoring are priced separately from basic uptime checks and add up.

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

• Very large global probe network with a long operating history.
• Simple to set up for basic availability monitoring.
• Combines synthetic checks with real-user monitoring.

• 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.

• Feature development has been slow under SolarWinds ownership.
• Transaction-check authoring is dated compared to code-first alternatives.
• Pricing is no longer competitive against newer entrants.

• 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.

Organisations wanting an established name for straightforward uptime monitoring.

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