HYPERNOVUM
Your projects become
a living 3D city. Your AI
agents work inside it.
Hypernovum is a free, open-source Obsidian plugin that turns your vault into a navigable code city where you launch Claude Code, Codex, or any CLI agent with full context. The optional Pro desktop app does the same for your real dev folder — with isolated worktrees and merge review, so agents never touch your code without your sign-off.
See
Every project is a building. Git activity is weather — active repos glow warm, stale ones cool down. One glance replaces twenty terminal tabs.
Launch
Click a building, pick an agent — Claude Code, Codex, Antigravity, or any CLI command. It opens in that project with full context injected.
Control
Pro runs each agent in an isolated git worktree. You read the per-file diff, then merge or discard. Nothing touches your main branch without you.
Same city. Two homes.
Free runs inside Obsidian on your notes vault. Pro is a standalone desktop app pointed at your actual code folder.

“To be honest: Insanely unnecessary. To also be honest: I installed it insanely quick. 12/10 would do it again.”

“It's giving Jurassic Park UNIX. I mean that as a compliment.”

“This is over the top, absolutely unnecessary, and of slightly dubious utility. *cough* instantly installed, very cool.”

Two agents. Zero collisions.
Tandem Terminal runs two agents side by side — each in its own isolated git worktree, so they physically cannot overwrite each other or your main branch. When they finish, you review each branch and merge only what you trust.
Questions, answered
What is an agent ops dashboard?+
Agent ops is the layer between you and your AI coding agents: launching them with the right context, watching what they do, and reviewing what they change. Hypernovum does this spatially — every project is a building in a 3D city, every active agent is a visible light, and every change flows through git isolation and merge review instead of straight into your codebase.
Is Hypernovum a 3D IDE?+
It's the 3D command layer of your IDE workflow, built on Three.js. You don't type code into the city — you dispatch AI coding agents from it, monitor their sessions in real time, review diffs, and merge. Pro adds a built-in CodeMirror 6 editor (Holodeck) for direct edits, terminals, and per-session git worktrees.
How does Hypernovum work with my second brain?+
The free Obsidian plugin reads plain markdown frontmatter — no lock-in, no database. Your project notes become buildings, your backlinks become glowing Neural Link arcs, and open questions in frontmatter become research quests that AI agents can discover and resolve. One command writes an AGENTS.md so any CLI agent launched in your vault understands your entire knowledge base.
Which AI coding agents are supported?+
Claude Code, Google Antigravity CLI (agy), and GPT Codex are supported out of the box, plus any custom CLI agent command. Pro's universal launcher, tandem terminals, and MCP server extend this to 6+ agents running side by side.
What's the difference between the free plugin and Hypernovum Pro?+
The free AGPL-3.0 Obsidian plugin is a complete second-brain agent-ops layer: 3D city, scan modes, quest board, Neural Links, fleet presence, and agent launching. Pro is a standalone desktop app (Windows/macOS) that works outside Obsidian on your real dev folder and adds persistent agent memory (Engram), git worktree isolation with merge review, Tandem Terminal, session analytics, webhooks, and an MCP server — $15 one-time, no subscription. Pro purchases fund development of the free plugin.
Is Hypernovum safe to trust with my code?+
Everything runs locally. The plugin and app read your files on your machine and never upload them anywhere — there are no accounts, no API keys, and no telemetry on your code. The plugin is AGPL-3.0 open source, so you can read every line before installing. AI agents you launch use your own tools (Claude Code, Codex, etc.) under your own credentials, and Pro isolates their work in git worktrees you review before merging.
What are the system requirements?+
Free plugin: any machine that runs Obsidian with WebGL 2. Pro desktop app: Windows 10+ (x64, .exe installer) or macOS 12+ (Intel or Apple Silicon, .dmg), 4 GB RAM minimum, about 250 MB of disk, and any GPU with WebGL 2 / Metal support. The macOS build is not yet code-signed — right-click → Open on first launch.

Install the city.
The plugin is free and open source, forever. If it earns a place in your workflow, Pro is how you keep it alive — and how you get the merge-gated desktop cockpit for your real repos.
