Crispy

A zero-compromise UI for Claude Code, Codex, and more — with controls you can't get in a terminal.

Rendered Markdown. Fork and rewind conversations. Multiple agent windows side by side. Audit tool calls and sub-agent work in a dedicated panel. One-click bypass, Chrome, models, and permissions. Execute Markdown files directly as prompts.

VS Code / Cursor extension today. Standalone browser app after v0.1.x.

Crispy — parallel sub-agents implementing light mode support

Why Crispy?

The official Claude Code VS Code extension is good. But it ships a subset of what the TUI can do, and it locks you into one vendor. Crispy fills the gaps.

Features

Fork and rewind conversations
Side-by-side agent windows — as many as your editor can tile
Dedicated tool panel for auditing tool calls and sub-agent work

Three rendering modes — Blocks for daily use, Compact for skimming, YAML for observability
Agency modes — plan, auto-accept, ask-before-edits, bypass
