About Rindler
Summary
Rindler builds browser infrastructure that lets AI agents operate on websites reliably. It handles authentication, navigation, form submission, and record retrieval, then returns structured output in a caller-defined schema. Operations teams use it to offload repetitive manual web tasks; agent developers use it as a single endpoint so they never have to build or maintain browser infrastructure themselves.
Go-to-market
Rindler targets two buyers: operations leaders whose teams do repetitive website work by hand, and developers building AI agents who need a managed browser execution layer. Both can reach it through a single API endpoint.

The translation layer between AI agents and the web
Rindler turns any website into deterministic abstractions that AI agents can operate on with speed, efficiency, and reliability. Rindler drives a real browser to execute tasks on websites. It signs in, handles one-time verification codes, navigates to the right screen, retrieves records or completes forms, and returns structured output in a caller-defined schema. Most browser agents re-process and re-compute the same website every time they visit it. Rindler remembers. Our infrastructure gets faster and cheaper the more it is used, and when a site changes underneath it, Rindler detects the break and heals itself. For operations leaders, Rindler takes on the repetitive website work your team does by hand, giving them their time back for the work that matters. For agent builders, Rindler is a single endpoint that carries out tasks on the web, so you do not have to build or run browser infrastructure of your own.
