Compare Bugsnag and Sentry free tiers side by side. Pricing, limits, change history, and risk assessment for developers.

Bugsnag vs Sentry

Side-by-side free tier comparison. Catalogue dates here run to 2026-08-11.

Verdict

Both Bugsnag and Sentry offer free tiers. Bugsnag provides "Free" while Sentry offers "Developer".

A verdict here is not a fixed property of the vendor. A one-off pricing event demotes a vendor while its recorded date falls in the last 180 days and then lapses on its own, with nothing about the vendor having changed; a standing condition — a free tier withdrawn and not restored, a product retired — does not lapse with time. A badge carrying a date states the record it rests on; a badge with no date rests on no record in force.
