Nimbalyst

Description

Nimbalyst is an open-source visual editor and full-context workspace for AI coding agents like Claude Code and Codex. Instead of working in a terminal, users see their agent's work in real time across markdown, mockups, diagrams, data models, and code, with inline diff review for every change.

It acts as a session manager and visual editor: users can run multiple agent sessions in parallel, organize them on a kanban board, and approve or reject each file change in place, with full session history visible. Nimbalyst supports Claude Code and Codex, with OpenCode, Copilot, and Codex via ACP in Alpha.

Nimbalyst is available as a desktop app for macOS (Apple Silicon and Intel), Windows, and Linux, plus an iOS app for managing sessions on the go. The desktop and iOS apps are MIT licensed and open source, and the core experience is free for individual use with no feature limits or trial period.
