## Description

addy.io (AnonAddy) is an open-source browser extension for anonymous email forwarding. It enables you to view, search, manage, and create aliases quickly, with login via your addy.io account or an API key, and an option to switch to your self-hosted instance when needed.

Note: The free plan restricts you to 10 active shared-domain aliases and 10MB of monthly bandwidth. You can still generate unlimited standard aliases on-the-fly (e.g., anything@username.anonaddy.com) without using the extension. The project is open-source and source code is available on GitHub.

## Review summary

Users broadly praise addy.io as a privacy-focused, fast, and easy-to-use email aliasing tool. The browser extension streamlines alias management, and the service is robust, feature-rich, and open-source with a generous free tier. Support is responsive, especially for questions. However, several reviews note that the documentation is incomplete and not beginner-friendly, the product can be overkill for casual users, and there are friction points like API-key setup and manual theme switching. Overall, it excels for power users who value control and anonymity.

- Requires API key generation rather than OAuth login, adding friction.
- Extension doesn't auto-switch to system themes; manual light/dark switching is needed.
