A dev machine that isn’t a machine.

Excede is a coding workspace that lives in a browser tab. Open it and your files, your editor and your terminal are already there — down to the line the cursor was on when you closed the lid. The code you write runs on the computer in front of you, at full speed, and the workspace itself follows you to the next one.

There is nothing to install, nothing to configure, and no machine to keep alive. It works on a laptop you own, a desktop you borrowed, and the locked-down school machine you are not allowed to put a compiler on.

Why it exists

Writing code usually starts with an hour of not writing code: install the toolchain, fix the PATH, find out the version is wrong, start again. Do that on a second machine and you do it twice. Change laptops and you do it from scratch — and the half-finished thing you were working on last week is still sitting on the old one.

The online editors that solve the setup problem tend to introduce a new one: your code goes to somebody else’s server to run. That means a queue, a cold start, a session that expires while you are thinking, and a limit on how much you may compute before somebody wants paying.

Excede takes a different split. Execution happens on your computer — it already has a processor, and it is doing nothing while you read this. Memory happens on ours: the files, the open tabs, the cursor. Split that way, the setup disappears without your work being handed to a server to babysit.

// the computer is temporary. the workspace is permanent.

How it works

1. 01

   Your code runs on your machine

   Programs execute inside the tab, on the hardware in front of you — not on a server you are sharing with strangers. No queue, no wake-up wait, no meter running. Interactive programs stay interactive: input stops and waits for you, output arrives as it happens, and Ctrl+C actually stops the thing.

2. 02

   The workspace outlives the tab

   Your files are stored, not cached — there is no container that quietly expires and takes your afternoon with it. Sign in somewhere else and the tabs you had open, the file you were in and the position you were at are all restored.

3. 03

   Your work is never stuck in here

   Real Git in the browser: clone, commit, push and pull. Connect a GitHub account and your work is versioned the ordinary way; skip it and you can still download your files whenever you like. Nothing about Excede is a one-way door.

What you can run

A real editor with the shortcuts you already know, a terminal that speaks ls, cd, git commit and npm install, and language support that is the whole language rather than a teaching subset of it.

• Python
• C
• C++
• JavaScript
• TypeScript
• Node
• Jupyter notebooks
• HTML / CSS

Start a dev server and a live preview opens beside the editor. Notebooks you write here open in Jupyter, VS Code or Colab — and theirs open here. Point Excede at a folder on your disk and it becomes a workspace, checked for keys and tokens on your machine first, with the final say left to you.

// anything else opens and edits fine — it just can’t be run yet.

What we hold to

• Nothing to install

  If it runs a modern browser, it runs Excede. No admin rights, no toolchain download, no “works on my machine” — because there is no machine to set up.

• Your computer does the work

  Running your code on your own hardware is faster, private by construction, and the reason there is no queue and no usage meter to watch.

• Your code stays yours

  It is not sold, not shown to anyone else, and not used to train machine-learning models. Excede stores your files to do one job: give them back to you. The Terms say so in writing.

• Honest about the edges

  This is a young project run by one person. Some things are missing, some will change, and the pages here say which rather than pretending otherwise.

Where it’s going

More languages that run rather than just open. Sharper code intelligence in the editor — real errors and go-to-definition, not just highlighting. Easier ways to hand somebody a workspace and have it open for them the way it looks for you.

None of that comes with a date on it. What is on the site today is what works today.
