Monitoring, uptime and error tracking

Sentry vs BugSnag

Sentry links errors, traces, replays and logs on one trace, with a free one-user plan and a self-hosted edition; BugSnag focuses on mobile crash reporting and per-release stability scores.

§1

The short answer

Both capture errors from most platforms and both have a free one-user plan. Sentry’s gives 5,000 errors and 5M spans a month with a 30-day lookback; BugSnag’s gives 7,500 events and 1M spans with 7-day retention.

Sentry Team lists $26 a month on annual billing with unlimited users and 50,000 errors, and Business $80 with SAML and SCIM. BugSnag’s own page did not show prices; third-party listings put Select from about $20 and Preferred from about $33 a month on annual billing, with SAML SSO on Preferred. Overages differ: Sentry drops new events once reserved volume and the pay-as-you-go budget are used, while BugSnag can upgrade your plan automatically after repeated overages of its daily quota.

Sentry’s strength is context: errors, tracing, session replay, logs and cron and uptime monitors share one trace, and a self-hosted edition runs with Docker Compose. BugSnag’s is mobile: crashes, ANRs and minidumps, errors ranked by user impact, and on-premises deployment on Enterprise for PCI and PHI compliance.

Strengths	Error grouping, release tracking and suspect commits are mature and cover most languages and mobile platforms. Errors, traces, replays and logs share one trace, so context is one click away. Usable free plan for a solo developer with 5k errors a month. Self-hosted edition available when data must stay on your own servers.	Strong mobile crash reporting and release stability tracking. Prioritises errors by user impact rather than raw counts. On-premises option for regulated industries. OpenTelemetry-compatible performance monitoring.
Limitations	The free Developer plan allows only one user. Events beyond the reserved volume and PAYG budget are dropped for the rest of the billing month. Profiling is only available through a pay-as-you-go budget. Seer AI debugging is an extra per-contributor subscription.	Free plan is limited to 1 user and 7 days of data retention. Exceeding the daily event quota more than 3 times in 30 days can trigger an automatic plan upgrade. Minidump events count as 5 events each for billing. SAML SSO requires the Preferred plan.
