Your AI agents get a machine of their own. Your laptop cools down.

Yes, and that is exactly why Pupitre exists. A server — a VPS, in the jargon — is simply a computer you rent from a host and that stays on all the time. You order it in three clicks, you get an address and a password by email, and you copy them into Pupitre. From there the app does the rest and explains what it is doing.

Nothing in particular. If you can install an application on your computer, you can use Pupitre. The app never asks you to type a command: it asks its questions in plain words, ticks the boxes for you when the answer is obvious, and when something goes wrong it shows the button that repairs it rather than an error message.

Only the server, which you pay to your host — count five to ten euros a month to start. Pupitre is free up to 3 servers per organisation, with no card asked for; beyond that, a licence is granted on request. Your Claude or ChatGPT subscriptions stay yours and do not change.

Your code, your data and your conversations with the agents live on your server. When an agent works, what it reads goes from your server to the model provider you chose — Anthropic for Claude, OpenAI for Codex — on your own account, never through Pupitre, and we keep no copy of it. The platform knows your server’s name and address, its architecture, the agent version, the services and terminal sessions it runs, its health readings and the status of its backups — never the contents of your files, databases or conversations. That is how it tells you when an update is waiting or a backup failed.

No, it is yours and you do what you like with it. It is an ordinary Ubuntu server and you are its administrator: you can host a site on it, run a service of your own, install tools that are not in the catalogue, or log in to it directly without opening the app. Pupitre installs and watches over what it put there, and touches nothing else: its work stops at setting up your remote development environment and keeping it up to date.

You uninstall the app. The server stays yours and keeps running exactly the same: your projects, your databases and your tools are all still there, set up with standard tools any developer can pick up. Pupitre locks nothing in and locks nothing down.

The app runs on Mac, on Windows 11 and on Ubuntu. The server you rent always runs Ubuntu: that is the system Pupitre knows how to set up, and the app checks that it is suitable before touching it. If it is not, it tells you before you have paid for anything.
