Open-source Obsidian plugin · Electron desktop app
Hypernovum
A 3D command center for AI coding agents: projects become buildings, agents run in isolated git worktrees, and nothing merges without a human review.

01 — Problem
The problem
Running several AI coding agents on real repositories is chaotic. They step on each other, the terminal wall gives no sense of what is happening where, and a bad merge lands before anyone reads it.
02 — Build
What I built
- A free, open-source Obsidian plugin (AGPL-3.0) that renders a vault as a navigable 3D city and launches Claude Code, Codex CLI, or Antigravity CLI into a project with context injected.
- A Pro desktop app ($15 one-time) that points at a real dev folder. Each agent runs in its own git worktree, changes go through per-file merge review, and nothing reaches the main branch without explicit approval.
- Tandem Terminal for two agents side by side, persistent per-project agent memory, git heat maps, session tracking, webhooks, and an MCP server whose action tools require in-app confirmation.
- A signed release pipeline with a GitHub-hosted auto-update feed, and a product page redesign that cut 14 sections to 6.
03 — Decisions
The decisions that mattered
Anyone can list a stack. These are the calls that changed the outcome.
Isolation is the product
The worktree-per-agent and merge-review features came from getting burned running agents on my own repos. The safety model is the reason to pay, not the visuals.
Free plugin is the complete product
The Obsidian plugin is not a trial. Pro exists for people who want it on a real dev folder and want to fund the open-source work.
Local-first, no telemetry on user code
Nothing phones home. That is a hard requirement for a tool that sits next to private repositories.

05 — Next
What I'd do next
- Obsidian community directory submission, the largest unclaimed distribution channel for the free plugin.
- Code-sign the macOS build.
