Verdict:Sentry's Developer plan covers one user and 5,000 errors a month, and the Team plan is $29 a month billed monthly or $26 billed annually. The code is under the Functional Source License rather than an OSI open-source license, which matters if ”open source” is a requirement for you. The easiest way out is GlitchTip. It is MIT licensed, self-hostable and compatible with Sentry's client SDKs per its site, so moving is mostly a matter of changing the DSN. It lists error tracking, performance, uptime and logs, but does not mention session replay. If you already want logs, metrics and traces in one place, SigNoz is an OpenTelemetry platform whose exception view only has stack traces when your SDK records them, so test that with your own language first. Better Stack advertises Sentry SDK compatibility with per-event pricing, and Rollbar offers a similar free quota with its own SDKs. New Relic's 100 GB free tier is generous, but it comes with a much larger product and an account model built around full-platform users. The trade-off is operations: self-hosting an error tracker means disks, upgrades and backups, and a quiet outage means errors you never saw. If your volume is small, the hosted free tiers are safer than a server you forget about. Run the alternative alongside Sentry for a week and compare what each one catches.

Sentry today: Free (Developer plan: 1 user, 5k errors, 5 GB logs, 5 GB application metrics, 5M tracing spans, 50 session replays); paid from $29 per month, billed monthly (Team; $26 billed annually) (Sentry pricing, checked 2026-10-22).
Why people look for Sentry alternatives
Sentry's free Developer plan is limited to 1 user, 5k errors, a 30-day lookback and email alerts only, with no API or third-party integrations and no SSO. Team is $29 per month ($26 annual) with 50k errors and Google and GitHub SSO; SAML and SCIM, unlimited dashboards and anomaly detection need Business at $89 ($80 annual). Logs and application metrics beyond the included 5 GB each are billed at $0.50 per GB, and the Seer AI add-on is paid separately. Self-hosting is under the Functional Source License, which is not an OSI open-source license.
