Hawk
Saint Petersburg, Russia
What it is
Hawk is an open-source error tracker that collects code exceptions and runtime errors to help teams investigate application problems. Event views can show stack traces, code snippets with local variables, request parameters, user system information, and details about affected users and occurrence counts. Users can filter, sort, assign, and mark events. A project health graph tracks how error counts change after releases. Official Catchers are listed for JavaScript, Node.js, React, Vue, Nuxt, Webpack, Vite, Python, Flask, FastAPI, PHP, Symfony, Laravel, Go, Android, Kotlin, and Java. Developers can also create a Catcher for an unsupported language or send data in Hawk’s Event format. Notifications are available through email, Slack, and Telegram, with configurable rules and filters. Hawk’s cloud service retains events for 30 days; teams needing longer retention are told to contact the company. Sensitive-data filtering is available server-side, and a before-send hook can remove fields. Hawk says data in transit is protected with TLS, passwords are hashed with Argon2, and backups are made regularly. The desktop application for Windows, macOS, and Linux is under testing; Hawk Web can be used in a browser.
For and against
For
- Event views include stack traces and request parameters.
- Tracks error-count changes after releases.
- Notifications support email, Slack, and Telegram.
- No stated limits on workspaces, projects, or team members.
- Lists Catchers for multiple languages and frameworks.
Against
- Events are retained for 30 days.
- Desktop apps are under testing.
- Longer event storage requires contacting Hawk.
The verdict
Hawk combines error investigation, event management, and release-related health tracking. Its 30-day retention period and desktop-app status are important limits to consider.
Who it suits
Hawk suits teams that need to collect and manage application errors and track changes across releases. It may also work for developers whose languages have a listed Catcher or who can create a custom one.
