Free plan · no card · your own keys or ours · CLI subscriptions on Pro · see plans
First run, in order: sign in (the free plan is free) · pick how the seats run — your API keys, the Claude Code, Codex, Gemini CLI or Grok Build install the app finds on your machine, or our keys · open a folder · tell the group what to build.
The Mac app where the group builds. One seat leads in a git worktree on your machine; the others read the diff, re-run your build and tests, and say what they found — on a receipt under every answer.

Package managers
macOS, with the ltb command included:
brew install --cask gpulogyai/tap/ltb
Ubuntu / Debian, and RedHat / Fedora — dependencies resolved by the package manager:
curl -LO https://letthembuild.com/downloads/letthembuild-linux.deb sudo apt install ./letthembuild-linux.deb
curl -LO https://letthembuild.com/downloads/letthembuild-linux.rpm sudo yum install ./letthembuild-linux.rpm
VS Code and Cursor
The room in the editor you already have open: review the file, the selection or your uncommitted changes, and the findings land as squiggles. It runs the app's ltb command, so install LetThemBuild first.
Or from the terminal, in either editor:
code --install-extension gpulogy.letthembuild cursor --install-extension gpulogy.letthembuild
The Windows installer is signed by GPULOGY AI LLC. Until the new certificate has built a SmartScreen reputation, Windows may ask once; choose More info → Run anyway. Checksums below.
The companion. Your sessions, your account, your plan — synced. Read what the group built while you were away, ask the four of them anything, steer the next round from your phone.
iPhone
iOS 17+ · voice mode, branching, team sharing
Android
Android 8+ · the web room, full-screen, with your Google sign-in
Web app
any browser · nothing to install
Install the web app, no download: in Chrome or Edge, look for the install icon at the right of the address bar — it puts LetThemChat in its own window with a desktop icon. It is the same web app; LetThemBuild above is the Mac app that works on your files.
Every plan includes every surface. Pay for the room, not the models: run seats on our keys, on a coding CLI you already pay for, on your own API keys (BYOK), or on any OpenAI-compatible endpoint such as DeepSeek or Together.
