What it does
Airbrake is an error and performance monitoring service with notifiers for many languages and frameworks. A notifier sends exceptions and application events to a project, where teams can inspect contextual details, group recurring problems, and connect errors to deployments. The JavaScript notifier is one documented route; other stacks use their matching library. Plans combine error and APM quotas, so the expected event volume matters when choosing a tier.
Start with the notifier for your application
The JavaScript guide shows installing Airbrake's browser notifier, then creating a Notifier with the project's ID, key, and environment. A first integration can call notify when an application catches a meaningful error; for example, a missing record might be reported with a short message instead of disappearing into a browser console. Keep the project key in the configuration appropriate for the application and use the right notifier for the codebase. Airbrake's error monitor groups reports and attaches context to help developers compare repeated failures. Deploy tracking adds release information, which helps answer whether an error appeared after a particular deployment. It does not replace the application log or explain every root cause automatically; use the event context and your own diagnostics together. The current pricing page lists monthly packages starting with a Developer plan and higher Basic and Pro tiers, with quotas for error or APM events. Compare included volumes and retention to expected traffic; a small monthly plan can be exceeded by a high-volume application.
Strengths
- Notifiers support many languages and frameworks, so teams can report errors from the stack they already use.
- Error context and grouping help distinguish recurring failures from unrelated events.
- Deploy tracking can place error trends alongside release changes.
Watch out for
- Plans impose event quotas and retention limits, so a high-volume service needs to monitor usage and choose an appropriate tier.
- An error notification identifies a reported event; application logs, traces, and code review may still be needed to find the cause.
Best for
- Application teams that want exception reports with project and deployment context.
- Developers integrating error reporting into browser-based JavaScript applications.
- Teams that want error and APM event quotas in one monitoring account.
