Bugsink
Bugsink collects exceptions from running applications and brings them together for developers investigating production failures.
What Bugsink is
Bugsink collects exceptions from running applications and brings them together for developers investigating production failures. It works with Sentry’s open-source SDKs, so an existing application can send events after its DSN is changed. Repeated errors are grouped into issues, and search and trends help users review, resolve, or mute them. Stack traces, code, and local variables provide debugging details. Alerts can go by email, Slack, Mattermost, Discord, Microsoft Teams, Telegram, or custom HTTP endpoints. Users can choose Bugsink-managed hosting or self-host the product on their own infrastructure. The company says hosted data is kept in the European Union, while self-hosted data stays on the customer’s infrastructure. The hosted free tier allows 15K monthly events, one user, and 5K retained events. Self-hosting costs nothing and includes unlimited users and all features, with volume based on hardware. Hosted paid plans include 75K events for $16 a month and 600K for $50 a month, each with unlimited users and matching retention allowances.
