About bb
bb is an AI coding agent built around the premise of an IDE that constructs itself around the work being done.
Its defining trait is that the environment runs entirely in the browser, with no local installation required before coding can begin.
It fits developers and tinkerers who prefer a web-based setup over configuring a local toolchain, and who want an environment that assembles itself in response to the task rather than arriving as a fixed template.
Within the broader category of AI coding agents, bb positions itself as a self-building, browser-native alternative focused on adaptive tooling.
