Read the privacy noticeThe framework Alex OS is built on — used for every route group (ask, surface, recommend, capture, synthesis, admin).
Alex OS is a FastAPI service, chosen for async support and the built-in request/response validation, which matters when every route is returning structured JSON blocks rather than free text.
FastAPI is the backbone of Alex OS, handling every route group from ask to synthesis with async support and built-in structured JSON validation.
Why FastAPI runs Alex OS
Alex OS is a FastAPI service covering six route groups: ask, surface, recommend, capture, synthesis, and admin. FastAPI was chosen for two concrete reasons — native async support keeps routes non-blocking, and built-in request/response validation enforces structure at every endpoint. That second point matters because Alex OS returns structured JSON blocks rather than free text, so schema enforcement isn't optional.
