What Bugsink is
Bugsink collects exceptions from running applications and presents them centrally so developers can investigate production failures. Applications using Sentry’s open-source SDKs can send events to Bugsink after their DSN is changed. Repeated errors are grouped into issues, with search and trends for reviewing, resolving, or muting them. Investigation views include stack traces, code, and local variables. Alerts can be sent through email, Slack, Mattermost, Discord, Microsoft Teams, Telegram, or custom HTTP endpoints. Bugsink is available as managed hosting or as a self-hosted deployment on a customer’s infrastructure. The company says hosted service data is kept in the European Union, while self-hosted data stays on the customer’s infrastructure. The hosted free evaluation plan allows 15K monthly events, one user, and 5K retained events. The free self-hosted plan includes unlimited users and all features, with volume based on hardware. Paid hosted plans include 75K monthly events for $16 a month and 600K for $50 a month, with unlimited users and matching retention allowances.
