Anon builds an authentication and integration layer that lets developers give AI agents and automation software the ability to log into and act on websites that have no public API. Daniel Mason, previously a partner at Framework Ventures and co-founder of Spring Labs, and Kai Aichholz, previously CTO at Alaffia Health, founded the San Francisco company in 2023.
Developers embed Anon's SDK in an application and call its API to authenticate a user, manage that session, and take permissioned actions on their behalf across sites that were never built with automation in mind. The platform ships SDKs across multiple programming languages and handles the credential and session management underneath, positioning itself as infrastructure for the current wave of AI agent builders rather than a consumer-facing product.
Anon suits developers and companies building AI agents, browser automations, or workflow tools that need to interact with third-party sites lacking APIs. A free tier is available to test the platform, with a Pro tier starting at $50 per month for expanded usage.
