Nimbalyst
Open-source visual workspace for building with Claude Code, Codex and other coding agents: run several agent sessions in parallel, review and approve their changes in a WYSIWYG markdown editor, and keep tasks, diagrams, mockups and a wiki your agents write in one desktop app.

Formerly Crystal (stravu/crystal). Desktop apps for macOS, Windows and Linux plus an iOS/Android companion for remote sessions.
