Visual editor for Claude Code
The visual editor for Claude Code.
Stop reading terminal output and trusting blind edits. See every Claude Code change as a red and green inline diff across markdown, mockups, diagrams, code, and data models. Approve or reject each one in place.
Claude Code is fast. Reading its diffs in a terminal is not.
Claude Code is one of the most capable AI coding agents in 2026. It is also a terminal application. For small edits that is fine. For real work, where the agent is rewriting many files at once, the terminal becomes a bottleneck for review.
Nimbalyst is a visual editor for Claude Code. It runs Claude Code as the agent underneath and surfaces every change visually: WYSIWYG markdown with inline diffs, side-by-side mockup edits, diagram changes you can see at a glance, and per-session file traceability so you always know which session changed what.
Why Nimbalyst
What a visual editor for Claude Code does that the terminal cannot
WYSIWYG markdown with AI diffs
Claude Code edits your markdown. You see the diff inline, in the rendered document. Approve or reject per change without reading raw markdown in a terminal.
Per-file diff review across the project
See every file Claude Code touched in a session. Navigate file by file. Accept the good edits, reject the bad ones, and keep going.
Visual editing for diagrams and mockups
Claude Code can edit Excalidraw diagrams, MockupLM UI mockups, and data model schemas. You see the visual change, not just the JSON behind it.
Session-aware editing
Every editor pane shows which Claude Code session made the current change. No more wondering which agent edited what.
