bb: the IDE that builds itself

eigenos.org Observed source

Editorial interest 78/100 Selection signal · not a rating of the site

An open-source, local-first coding environment that presents itself as an IDE capable of controlling, customizing, and automating its own workflow.

Landing page captured for the 2026-09-04 issue.

Field notes

bb presents a task-oriented coding workspace rather than only a chat interface. Its example follows a Sentry checkout error from repository exploration through a guarded code change and regression test, with the work tracked in the `bb/triage-sentry-spike` worktree. The page shows installation through `npx bb-app@latest`, support for macOS, Windows via WSL, Linux, and remote machines, and compatibility claims spanning Claude Code, Codex, Cursor, and other coding agents.
