⬤ One link without setup

Code together in one link

Open a room, send the link, and you are both typing in the same file. You can see their cursor moving around, you share one terminal, and the code runs right there in the tab. Nothing to install on either end.

⬤ Why Riverge

Pair, review and teach
without the setup

It runs in a tab you already have open.

Multi-cursor editing

You see their cursor with their name on it, moving through the file while they type. Nothing to merge, nothing to pull. Git still works when you want it, this just sits before that part.

Shared terminal

One terminal everybody can see. Somebody hits run and the output shows up for all of you at once, which makes debugging together a lot less painful than reading errors to each other.

One link to join

Send the URL and they are in. They do not need an account to watch, and nobody has to spend twenty minutes getting their environment to match yours.

⬤ How it works

Three steps, about ten seconds

Usually faster than getting everyone onto a video call.

1

Open a session

Hit start. You get a fresh room in your browser, straight away.

2

Share the link

Paste the link into chat, or pull someone in from your favourites. They land in the file you are already in.

3

Build and run live

Type at the same time, run it, argue about it, fix it. All in the same place.

⬤ Use cases

Ways people actually
use it

People use it for all sorts of things. A few we see a lot:

Teaching & tutoring

Write it out while they watch, then hand them the keyboard and see if it sticks.

Debug with a friend

Send a link instead of a screenshot. They can poke at the actual code.

Study groups

Work through the problem set together at 1am, which is when it always happens.

Pair programming

Both of you on your own keyboards, no screen share, no asking someone to scroll up.

Workshops & streams

Let the room follow along and jump in when they want to try something.

Mob programming

The whole team in one file, taking turns at the wheel.

⬤ Questions

Quick answers

Do people need an account to join?

No. Anyone with the link can spectate right in the browser, no account needed. To edit code you need an account, and you need one to create rooms and keep your work.

What can it run?

JavaScript, TypeScript, Python and HTML run right in the browser today, with more on the way.

Is it actually real-time?

Yes. Cursors, edits and terminal output all move in real time, so you are looking at the same thing they are.

How is this different from a screen-share?

On a screen share only one person can actually type, and everyone else is squinting at a compressed video of your editor. Here everybody can edit and run the thing themselves.

Can I use this to interview engineers?

We built a separate thing for that. Meritan adds recording and anti-cheating for interviews.
