Hawk is an open-source error tracker for collecting code exceptions and runtime errors so teams can investigate application problems.
What Hawk is
Hawk is an open-source error tracker for collecting code exceptions and runtime errors so teams can investigate application problems. Event pages can include stack traces, code snippets with local variables, request parameters, user system information, and details about affected users and occurrence counts. Teams can filter, sort, assign, and mark events. A project health graph shows how error counts change after releases, supporting release tracking and application health monitoring. Official Catchers are listed for languages and frameworks including JavaScript, Node.js, React, Vue, Python, PHP, Go, Android, Kotlin, and Java; developers can build custom Catchers or send data in Hawk’s Event format. Notifications can go to email, Slack, or Telegram, with configurable rules and event filters. The cloud service retains events for 30 days, and Hawk says teams needing longer storage should contact them. Sensitive-data filtering is available server-side, with a before-send hook to remove fields. Hawk states that it uses TLS in transit, Argon2-hashed passwords, and regular backups.
Good
- Event pages include stack traces and request details.
- Tracks error counts across releases.
- Notifications support email, Slack, and Telegram.
- No limits on workspaces, projects, or team members.
Watch out
- Events are retained for 30 days.
- Desktop apps are under testing.
- Longer event storage requires contacting Hawk.
Who it suits
Hawk suits development teams that need to collect, review, and track application errors across supported languages or frameworks. It also offers a custom Catcher path for unsupported languages.
Verdict
Hawk combines detailed error events with release health tracking and configurable notifications. Its 30-day retention window is a key limit to consider.
