Install
The installer downloads the already-compiled program, not a package that needs another runtime: nothing else is downloaded. On macOS it comes signed and notarised by Apple, and the installer checks that signature before leaving it on your machine — if the file is not the one we published, it stops. It is all in the installation guide.
$ curl -fsSL https://theus.pe/install.sh | bashConnect
theus and connect with theus login.The CLI opens theus.pe in your browser, you authorise, and the API key comes back on its own through a local callback. There is no need to register first: the link that reaches your inbox also creates your account, lives for fifteen minutes, and the CLI waits exactly that long. From there, one account gives you CLI, chat, console and API. The catalogue of 190 servable models is tiered: the free plan opens 2 so you can try it, and the frontier models start at the first paid plan — the detail is in pricing.

First session
Go into your project folder and run theus. Write an instruction — fix a bug, explain a module, write a function — and the agent reads your code, proposes edits you approve or reject, and runs commands with your confirmation. You stay in control at every step.
$ cd mi-proyecto && theus> Corrige el error del formulario de login y ejecuta las pruebas
Resume
theus -c and carry on.Every conversation is saved in the folder where you had it. theus -c resumes the most recent one for that project with the context already in place, and theus -r opens the picker so you choose which. To continue a conversation without writing over the original, add --fork-session. And inside the session, /resume does the same without leaving the CLI.
$ cd mi-proyecto && theus -c-> retoma la última conversación de esta carpeta$ theus -r-> abre el selector para elegir cuál
ÑaupaOptional
Ñaupa is the code intelligence engine of Theus: free, with the index on your disk, written in pure C. It parses the AST of 158 languages, builds a knowledge graph of your repository and exposes 19 MCP tools from a static binary. The whole index lives on your machine. The step 1 installer already includes it, on all three systems: this command is only needed if you skipped it or want to reinstall.
