Each error monitoring tool in brief

1. Sentry

Sentry suits small teams that need SDKs for most languages and mobile platforms, with a free plan to start and a $26 paid plan. You can choose US or EU storage and run the server yourself. The catch: the server licence is source-available, not open source, and SAML sign-in costs $80 a month on Business.

Best for: Small teams that want wide SDK coverage and the option to self-host. Prices, facts and sources

2. BugSnag

BugSnag suits teams that ship web and mobile apps and want source maps, dSYM and ProGuard handling in one tool. The paid plans start at $20 a month for 50,000 events, and SAML needs the higher Preferred plan. The catch: the free plan keeps only 7 days of history, SAML needs the Preferred plan, and its data centers are in the United States.

Best for: Teams with web and mobile apps that want readable crash reports and an on-premise option. Prices, facts and sources

3. Honeybadger

Honeybadger suits small teams on web stacks who want one clear price and error history that lasts 90 days on the first paid plan. It covers all six web languages we count, source maps, iOS symbol files and common alert and ticket tools. The catch: no Android or Flutter library is listed, and no self-hosting instructions are published. The free plan keeps errors for only 15 days.

Best for: Small web teams that want flat pricing and many language libraries. Prices, facts and sources

4. Rollbar

Rollbar suits web teams that want low entry prices, deploy tracking and integrations with Slack, Teams, PagerDuty, Jira, GitHub and GitLab. The catch: it is hosted only, publishes no EU region, lists Flutter as unsupported.

Best for: Small web teams that want cheap paid tiers and deploy tracking. Prices, facts and sources

5. GlitchTip

GlitchTip suits small teams that want Sentry-compatible SDKs, an open-source MIT server and low hosted prices. It offers an EU instance in Germany and 90-day history. The catch: the docs name only email and webhooks for alerts, list no SOC 2 or ISO certificate, and say little about ticket integrations.

Best for: Small teams that want Sentry-compatible tracking with an MIT-licensed server they can self-host. Prices, facts and sources

6. Airbrake

Airbrake suits small teams that want low-cost entry and a SOC 2 Type II certification the vendor names. Source maps, breadcrumbs, deploy tracking and Slack, Teams, Jira, GitHub and GitLab links are documented. The catch: history is 30 days, PagerDuty is marked as coming soon, and the free plan's limits are not published.

Best for: Small teams that want simple, low-entry pricing and a SOC 2 Type II certification. Prices, facts and sources

7. Raygun Crash Reporting

Raygun suits teams that want 180 days of error history and unlimited members from $40 a month. It covers all six server languages and four mobile platforms we count, with source map and dSYM upload documented. The catch: there is no free plan, only a 14-day trial, data stays in the US, and SAML needs the Business plan or a $50 a month add-on.

Best for: Teams that want long error history and unlimited members at a fixed monthly block price. Prices, facts and sources

8. Better Stack Error Tracking

Better Stack Error Tracking suits teams that want to keep their Sentry SDKs and pay only for what they send, with a free allowance of 100,000 exceptions a month and a stated SOC 2 Type 2 compliance. It has spike protection and source maps for JavaScript. The catch: mobile crash reports from obfuscated release builds cannot be symbolicated, and the pricing page shows no fixed paid plan.

Best for: Small teams that already use Sentry SDKs and want usage-based billing. Prices, facts and sources

9. AppSignal

AppSignal suits web teams on Ruby, Elixir, Node.js, Python or PHP who want error tracking and performance in one plan with unlimited users. Source maps, breadcrumbs, deploy markers and alerts to Slack, Teams, PagerDuty and email are documented. The catch: pricing counts requests, not error events, there is no mobile or.NET library, and SAML sign-in is a business feature.

Best for: Ruby, Elixir, Node.js and Python teams that want errors and performance in one tool. Prices, facts and sources

10. Firebase Crashlytics

Crashlytics suits mobile teams, since it costs nothing and handles dSYM and mapping files for readable crash reports. Its docs list no web or server SDKs, and its pages state no event limit, while the privacy page gives 90 days of crash history. The catch: it covers mobile apps only, and Firebase lists it as a global service without naming an EU region.

Best for: Mobile teams that want free crash reports and already use Firebase. Prices, facts and sources

11. Exceptionless

Exceptionless suits small.NET and JavaScript teams who want an open-source server they can host themselves, or a cheap hosted plan. It documents source maps, version tracking, Slack and webhooks. The catch: its clients cover only two languages, the free plan keeps events 3 days, and its pricing, security and docs pages name no SOC 2 report, SSO or EU region.

Best for: Small .NET and JavaScript teams that may want to self-host. Prices, facts and sources

12. TrackJS

TrackJS suits teams that only need JavaScript errors from the browser or Node.js, with a timeline of what the visitor did before an error. Pricing follows page views, not errors, and users are unlimited. The catch: no free plan, 10 days of history on Starter, no mobile or other-language libraries, and alerts reach only email, Slack and Microsoft Teams.

Best for: Front-end teams that only need JavaScript error tracking. Prices, facts and sources

We read each vendor's own pages, record every fact with its source and date, and score it by the rules on how we score error monitoring tools. A tie goes to the lower price. Hosted or self-hosted error and crash tracking for small teams. Full observability suites, uptime checks and session-replay-only tools are left out. "On at least one plan" counts any published plan, including quote-priced ones. Price lines describe the hosted service; an entirely free product counts as $0. Vendor claims about speed or quality are shown on product pages but never scored. Prices are in US dollars before tax.
