8 Best Sentry Alternatives in 2026: Error Tracking Priced per Event

A Sentry alternative is an error tracking service that captures exceptions from your application, groups them into issues with stack traces and context, and alerts the team, priced on the number of errors it ingests rather than on seats. Teams shop around for two reasons: Sentry's free Developer plan stops at 5,000 errors and one user, and its Team plan bills every error above 50,000 at a per-event rate. This page lists the free allowance of eight alternatives and computes what each charges at 100,000, 500,000 and 1 million errors a month, so the switch is a bill before it is a migration.

Toolradar data: in the Toolradar debugging ranking, the software directory we run, Sentry is listed as an alternative to 43 other tools, the most of the 93 debugging tools tracked as of October 26, 2026, and it was the most compared debugging tool over the last 90 days with 275 side-by-side comparisons. The crowd of alternatives is the point: nobody leaves Sentry for lack of options, they leave over the invoice.

Error tracking tools sit between your application and your on-call rotation. An SDK in the app catches unhandled exceptions (and handled ones you choose to report), sends them with a stack trace, breadcrumbs, release and user context, and the service de-duplicates them into issues, assigns them, and alerts Slack or PagerDuty. The billing unit is the event: an error, exception or occurrence, counted per month. The tools differ on how many events are free, what an extra thousand costs, how long events are retained, and whether the service also wants to sell you logs, traces and session replay. Every tool on this page has a free tier or a flat entry plan, and six of the eight are priced on a public per-event ladder you can read without a sales call.

At 1 million errors a month the bill runs from about $68 to over $500 depending on the vendor, from the same price lists. Sentry Team on pay-as-you-go is about $225, PostHog about $178, Rollbar Essentials $199 on monthly billing, GlitchTip $135 with on-demand events, and Better Stack about $68 at the middle of its three regional rates (our arithmetic, detailed below). The spread is wide because the free allowances differ by a factor of 100 (1,000 events on GlitchTip, 100,000 on PostHog and Better Stack) and the overage rates by a factor of five. A noisy release that throws 1 million errors in a week is cheap on some of these tools and a budget conversation on others.

Read the free allowance before the entry price, because it decides whether you pay at all. At 100,000 errors a month, PostHog and Better Stack cost $0, GlitchTip $15, Bugsnag $33, Raygun $40 on annual billing, Rollbar Essentials $49, and Sentry Team about $44 on pay-as-you-go (the $26 yearly base plus 50,000 extra errors at $0.0003625). At 500,000, Better Stack is about $30 at its middle regional rate, GlitchTip $50 on Medium, PostHog about $108, Rollbar $119 and Sentry about $132. At 1 million, Better Stack is about $68, GlitchTip $135 (Medium plus 500,000 on-demand events at $0.17 per 1,000), PostHog about $178, Rollbar $199, Sentry about $225 and Raygun Business $400. All of these are our arithmetic from the rates printed on each vendor's page on October 26, 2026; Sentry's figures use its Team pay-as-you-go ladder, and reserved volume on Sentry is cheaper, as our Sentry pricing page shows.

Three rows need a caveat. Honeybadger and Bugsnag print the entry pack but not the higher tiers, so their 500,000 and 1 million columns read check the vendor's site. Datadog prints a per-thousand rate above 50,000 errors but bills it on top of APM and RUM, and errors inside those products are free, so its column depends on what you already run. Better Stack prints three regional rates; the totals above use $0.000075, the middle one, and the highest region pays more than twice that. The best error tracking tools page ranks the paid tiers on features; this page is only about the invoice.
