Agentopolis — Habbo-style visualization of Claude Code agents building your repo as a city

Agentopolis

A Habbo-style isometric visualization of Claude Code at work, in two views on one page. The dispatch floor (City Hall): every agent is a pixel worker — your main session checks in at reception, subagents walk through the door when spawned, and tool calls send workers to stations — the CRT terminal for Bash, the archive shelf for Read/Grep, the workshop for Edit/Write, the telephone booth for web tools. The skyline above: the city is the codebase itself, seeded from git history and zoned by architecture (a zoning manifest maps globs to components and layers; floors = cross-component centrality, footprint = lines of code, window glow = recency, building shape = language family — pyramids for scripting, glass drums for web, ziggurats for compiled, toggleable to key off rarity/size/age instead; managed services float as tethered clouds). As agents work, the city builds itself out — edits wrap buildings in scaffolding, a git commit drops the scaffolds and adds floors, new files pop up new buildings. /city.html is a full-screen explorer with pan/zoom. The city re-seeds itself from git whenever HEAD moves.

Install & run

uv tool install agentopolis         # or: pipx install agentopolis
                                    # or: brew install codeblackwell/tap/agentopolis

cd ~/code/any-repo
agentopolis .                       # zero-setup: hooks attached, city on :4242, hooks removed on exit

agentopolis movie                   # replay this repo's git history as a growing city
agentopolis movie ../other-repo     # …or any local repo
agentopolis movie https://github.com/owner/repo   # …or any public github repo

agentopolis crawl ~/code            # rank a folder of repos by movie potential
agentopolis marathon ~/code         # play every repo's movie back-to-back, with a selection bar

agentopolis . is the one-command path: it attaches the Claude Code hooks on start and removes them again when you quit (Ctrl+C) — no separate setup or teardown. Open http://localhost:4242, then start any Claude Code session and it reports in automatically. No live session handy? http://localhost:4242/?demo runs a scripted day in the city.

Prefer persistent hooks? agentopolis attach wires them once (a backup of settings.json is written), agentopolis then just serves, and agentopolis detach removes them. agentopolis . leaves a manual attach untouched. Flags: --repo, --port, --zone.

First visit? A guided onboarding tour spotlights each part of the interface, narrated by a pixel "Chief of Staff" — replay it anytime from the ⭐ badge. See docs/tour.md.

Movie mode (agentopolis movie [target]) replays a repo's whole git history as a city that grows and re-forms commit by commit. target is a local repo dir or a public github url; github repos download only the minimum git data (a blob:none clone removed right after seeding) and the city is held in memory only. Run outside a git repo and agentopolis tells you how to point it at one instead of opening a blank map.

Crawl & marathon scan a folder of repos. agentopolis crawl <folder> ranks them by movie potential (formation ladder, history length, deletions). agentopolis marathon <folder> then grabs every repo's movie and plays them best-first in one auto-advancing reel with a selection bar to jump around — all local and offline, and cached per repo+HEAD so the next run is instant. --top N caps the playlist.

Zoning: if the repo has a .agentopolis.json manifest it defines the city's components, layers, and clouds (see city/example.json for a full example); otherwise agentopolis auto-zones from the repo's top-level directories.

How it works

Claude Code hooks ──curl──▶ POST /hook ──▶ normalize ──SSE──▶ canvas renderer

• hooks.py registers a curl -m 1 ... || true command on eight hook events (SessionStart, UserPromptSubmit, Notification, Pre/PostToolUse, Stop, SubagentStop, SessionEnd). It never blocks Claude Code — if the hotel isn't running, the curl times out silently.
• server.py (FastAPI) trims each payload to {event, session, tool, detail} (plus agent_id/agent_type for events fired inside subagents), keeps the last 100 events, and broadcasts over SSE — late-joining browsers get a replay.
• static/render.js + static/hotel.js draw the room and guests on a plain canvas — original pixel art, no Habbo assets. Subagent tool calls move their own guest, a pulsing gold aura marks a session waiting on you (permission or idle), and hovering a guest shows who they are and what they're doing.
