Two front-ends, one brain
An interactive terminal REPL and an Electron desktop app share the same agent loop, tools, sessions, and permissions.
Open source · Terminal + Desktop
An AI coding agent
that lives in your project.
VoidCoder is a small, transparent harness that reads your files, edits them with your permission, runs commands, spawns sub-agents, and remembers everything — across sessions, across front-ends.
$ voidcoder "refactor the auth module and add tests"
▶ reading project context… ✓ 2 sessions remembered
▶ tool: read src/auth.js (12 edits available in undo)
▶ tool: edit src/auth.js — index 143 → “hashPassword”
⊕ propose · ask permission to run: npm test
✓ 3 files changed · all tests pass
═══ you can /undo, /diff, or continue █Features
Built like a good terminal tool
should be.
Any model provider
OpenRouter, OpenAI, local Ollama, llama.cpp, or any OpenAI-compatible endpoint. Local models need no API key.
You stay in control
Per-category permissions (allow / ask / deny) and autonomy levels mean it only runs what you approve.
Remembers everything
Sessions persist, with /undo snapshots and live diffs for every change. Nothing is lost between launches.
Sub-agents & research
Background focus agents with time budgets, plus timed research sweeps that keep searching until the budget is gone.
MCP & live model catalog
Connect Model Context Protocol servers. Query a live catalog of installed and remote models — never a fixed list.
How it works
A transparent agent loop.
-
01
You ask, in plain language
Run it in your project and describe what you want done.
-
02
It reads your context
Reads files, checks your instructions, and recalls prior sessions.
-
03
It proposes & edits
Streams responses, shows diffs, and asks permission before running anything gated.
-
04
You review & finish
Undo, diff, or keep going. Everything is saved for next time.
Get it
A real installer. Under an open-source license.
Download the VoidCode desktop app for Windows, or grab the source and run it anywhere. Either way, it's MIT-licensed and fully inspectable.
Windows: the installer installs the desktop app (x64). It isn't code-signed yet, so SmartScreen may warn — that's expected; click More info → Run anyway.
macOS / Linux / from source: clone the repo and run npm start (terminal) or npm run app (desktop). The repo also includes installer.ps1 for a scripted Windows install.
Documentation
Built to be understood.
No build step. No dependency tree. A handful of small files you can actually read.
