GitHub - gpu-cli/agentis: Simulate your Claude Code sessions in a retro 2D game environment

Visualize your AI coding sessions as an interactive pixel-art world.

License: MIT

What is this?

Agentis turns AI coding agent transcripts (Claude Code, Cursor, Copilot, and more) into a living, explorable game world. Repositories become islands, modules become districts, files become buildings, and agents animate their actions as your session unfolds.

Privacy-first by design: transcript parsing and visualization run entirely on your machine. No cloud processing, no data leaves your device.

Quick Start

That's it. Auto-discovers your Claude Code sessions from ~/.claude/projects/ and opens a local visualization at http://127.0.0.1:3456.

Options: --port <number>, --no-open (skip browser). See npx @gpu-cli/agentis --help.

From source

git clone git@github.com:gpu-cli/agentis.git
cd agentis
pnpm install
pnpm dev              # Start dev server on :3000 with auto-discovery

Or build the standalone bundle (what npm users get):

pnpm build:local      # Build standalone bundle
pnpm local:run        # Start local server

Supported formats today:

  • Claude Code JSONL
  • More transcript formats coming soon

Commands

pnpm dev              # Dev server on :3000
pnpm build            # Production build

pnpm test             # Run tests
pnpm lint             # Lint
pnpm build:local      # Build @gpu-cli/agentis bundle
pnpm local:run        # Run local server
pnpm local:pack-run   # Package + run via npx (tests real artifact)
pnpm local:clean      # Remove bundle/tarball artifacts
