Built for web, mobile and server apps, with a solo plan that costs nothing. Bugsnag is an error monitoring and application performance tool for web, mobile and server apps. Its free plan costs $0 a month for one user and includes 7.5K events and 1M spans a month, with 7 days of data retention noted in a footnote. Higher plans list unlimited users, 60-day retention, custom notifications and automatic error prioritization, and the page shows a $20 a month tier and a Preferred plan starting at $33 a month. G2 shows 4.3 from 38 reviews, with 60 percent giving five stars, and Capterra shows 4.7 from 16. Reviewers praise real-time alerts, a clean dashboard and an interface that is not cluttered, and the review count is small compared with Sentry.

👍 Good boy
+The free plan costs $0 and covers both error events (7.5K a month) and performance spans (1M a month).
+G2's comparison summary says users like Bugsnag's real-time error tracking, customizable alerts and clean dashboard.
+A Capterra reviewer wrote that the interface is modern and not too cluttered, and that it aggregates all errors and provides stats on them.
+Another Capterra reviewer described it as a Sentry-like approach that logs all uncaught exceptions in production apps.
+Paid plans give unlimited users, and the page lists automatic error prioritization, custom notifications and SAML single sign-on on higher tiers.
+G2 shows 60 percent of reviews at five stars and 31 percent at four, from 38 reviews.
👎 Watch out
−The free plan is one user with 7 days of retention, which is short for tracking a bug that shows up weekly.
−Paid retention is 60 days and event packs start at 50k events, so you pay to extend history.
−The pricing page lists a $20 tier and a Preferred plan from $33 a month, and the labels are not clear in the text I read, so confirm which plan has the features you want.
−G2's comparison page with Sentry lists limited features among Bugsnag's few recurring cons (2 mentions), and Sentry has far more reviews (21 mentions of ease of use against 3).
−The review base is small: 38 reviews on G2 and 16 on Capterra, so the ratings are a thin sample.
−Premium features such as feature flags, sensitive data management and a dedicated customer success manager sit on higher tiers.
The catch
The free plan is for one user, and its 7-day retention is stated in a footnote under the pricing table. If you want a team to share issues or history longer than a week, you move to a paid plan.
The pricing page I read shows a $20 a month tier and a Preferred plan starting at $33 a month, but the plan labels were not clear in the text. G2's pricing page gives a range from $0 to $33. Confirm the plan names and event packs on the page before you decide.
Bugsnag has far fewer public reviews than Sentry. I did not find a commercial use clause or a card requirement for the free plan.
