Web-based coding workspace

Your dev machine,
in a browser tab.

Write it, run it, close the tab. It’s all still there tomorrow.

// about

A coding workspace that lives in your browser.

Excede lets you write code, run it, and pick up exactly where you left off — from any device, without setting up a machine. Open a tab and your editor, files, and terminal are already there, down to the cursor position in the file you had open.

The clever part is where the work happens: on your own computer. Your code runs on the machine in front of you, at full speed — nothing is uploaded to be run, there is no queue to wait in, and no session that expires while you are thinking. We do one job on our side: remember your files, so the workspace outlives the machine you opened it on.

// your machine does the running. we just do the remembering.

The longer version

// languages

Real languages, running on your own computer.

Your code never leaves for a server to be run. It executes on the machine in front of you, in the tab, at full speed — so there is no queue, no wake-up wait, and no meter running. Interactive programs stay interactive: input waits for you, output arrives as it happens, and Ctrl+C stops the thing.

Everything elseopens and edits

Python

Full Python, not a cut-down version of it. input() waits for you like a real terminal, and the libraries you reach for — numpy, pandas, matplotlib — are there when you import them.
C and C++

The whole language, not a teaching subset. Templates, exceptions, the standard library, and a scanf that actually stops and waits for what you type.
JavaScript and TypeScript

npm install what you need and start a dev server — it opens in a preview pane next to the editor. TypeScript just runs; there is no build step to set up.
Jupyter notebooks

Cells, plots, and a namespace that still remembers what you defined three cells ago. Notebooks you write here open in Jupyter, VS Code or Colab — and theirs open here.
HTML, CSS and static sites

Hit Go Live and the page is up instantly — nothing to configure, nothing to wait for. Save a file and the preview is already showing it.

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

// what it does

Everything a dev machine gives you, minus the machine.

01

Editor and terminal that behave

If you know VS Code you already know this editor — same feel, same shortcuts — with a terminal that speaks ls, cd, git commit and npm install. Search reads every file in the workspace and drops you on the line.
02

A workspace that outlives the tab

Your files are stored, not cached — no container that expires and takes your afternoon with it. Reopen on another machine and the tabs, the open file and the cursor are exactly where you left them.
03

Git, when you want it

Clone, commit, push and pull with real Git in the browser. Connect GitHub and your work is versioned; skip it and the workspace still keeps every file. Your code is never trapped in here.
04

Bring a folder in from your machine

Point Excede at a folder on disk and it becomes a workspace. Everything is checked for keys and tokens on your machine first, and you get the final say — so a stray .env never leaves your computer at all.
05

Ten themes, all the way down

Pick one and it lands everywhere at once — editor, terminal, sidebar, settings — with no half-themed white rectangle in the middle of the screen. Two of them are light, for the people who ask.
06

Nothing to install, on anything

A school laptop, a borrowed desktop, a machine you are not allowed to install compilers on. If it runs a modern browser, it runs Excede — and your code runs on it, not on somebody else’s server.

// word of mouth

From people who closed the tab and came back.

Students on locked-down laptops, teachers with thirty machines to set up, and developers who just wanted their cursor where they left it.

“I’ve been doing my C assignments on the library computers between classes. Didn’t have to install anything, which is good because they don’t let you.”

Priya Raman
Second-year CS student
“Used it with my intro class this term. Most of them are on school Chromebooks and it worked on all of them without me setting anything up. That was honestly the main thing I needed.”

Marcus Oyelaran
High school CS teacher
“I mostly use it on my old laptop when I’m away from my desk. Opened it on my home PC later and my tabs were still open where I left them.”

Dana Kowalczyk
Backend engineer
“The import warned me about a .env file with keys in it. I’d forgotten that was even in the folder. Good catch.”

Tomás Vieira
Indie developer
“I’m learning Python and a lot of the online editors I tried didn’t handle input() properly. This one does, so I can actually do the exercises from my course.”

Aiko Tanaka
Self-taught, three months in
“Notebooks load quickly and my variables are still there when I come back. Would like a few more keyboard shortcuts, but it’s been solid for quick analysis.”

Ravi Menon
Data analyst at a freight startup
“Ran a small Vite project in it without any setup and the preview opens next to the editor. It’s become my go-to for quick prototypes.”

Jess Albright
Freelance frontend developer
“A few of my students couldn’t install anything on their work laptops. We got them on this and they were running code the same day.”

Sam Whitlock
Bootcamp instructor
“Fine for contest-sized problems. I mainly like that Ctrl+C actually kills a runaway loop instead of freezing the whole tab.”

Leo Brandt
Competitive programmer
“Tried a couple of the themes and they apply everywhere, terminal included. Small detail, but I noticed.”

Noor Haddad
Design engineer
