About Blurts Server
Blurts Server is the open source code repository for Mozilla Monitor, the service at monitor.mozilla.org. The project is described as providing tools to keep personal information safe and to find out what hackers already know about you. The repository summary states that Firefox Monitor notifies users when their credentials have been compromised in a data breach.
The code covers the monitor.mozilla.org service and website. Breach data is powered by haveibeenpwned.com. The repository includes an API contract in openapi.yml for the Firefox-facing API, documentation, localization files, and development and test configuration. Developers can inspect the implementation, review how breach alerts work, and set up a local copy using Postgres manually or with Docker Compose.
It suits developers, researchers, and contributors who want to study, run, or contribute to Mozilla Monitor's breach-checking code, rather than general users looking for a hosted check.
