A complete computer · in a browser tab

Your desktop.
In a tab.

A full operating system that boots in seconds — Tab Code, terminals, compilers for 13 languages, an office suite. No install. No servers. Just a tab.

Enter Tab Desktop →

Clone any git repo — it opens in Tab Code with its README, and Harbor knows how to run it

Tab Code

A full VS Code-class editor — extensions, source control, integrated terminal — living on your in-tab filesystem.

13 languages, zero installs

Node, Python, Rust, C, Java, PHP, Ruby and more — compilers included, all executing inside the tab.

A real shell

git, npm, pnpm, composer, sqlite — clone 100 MB repos, install dependencies, run dev servers. In a tab.

No servers. Ever.

Everything — files, builds, even WordPress — runs on your machine, in your browser. Nothing to trust but math.

The real toolchain, running in the tab

Not mockups of the logos — the actual runtimes, compiled to WebAssembly, executing on your machine.

$ nodeNode.js runtime — Vite, Next, Express, Strapi
$ gitclone, commit, push — the real protocol
$ npm · pnpm · yarnthe package managers, lockfiles and all
$ phpPHP 8.3 — WordPress and Laravel boot in-tab
$ composerPHP dependencies, autoloading, scripts
$ sqlite3real databases, queried in place
$ pythonCPython, with the scientific stack
$ rustc · gcc · javaccompilers for 13 languages
$ wpthe WordPress CLI, against your in-tab site

Start with a stack

One click gives the stack its own isolated desktop: the project is scaffolded and committed to git, Tab Code opens on it beside Harbor, and the dev server runs in its terminal. Nothing is installed on your machine.
