Codarc is the visual representation
of the codebase you already built.

Codarc reads your code and draws the whole thing as a picture. Click any part, say what you want changed in ordinary words, and it writes the change and hands it back for you to approve.

Your first app is drawn free. You don't need to know how to code — you do need to own the app you're changing.

How it works

From your code to a finished change, in four steps.

No code editor. No terminal. Nothing you have to learn first. If you can describe what you want, you can do this.

1

Point it at your app

Give Codarc permission to look at a project you already keep on GitHub. If it's public you can paste the link and skip signing up entirely.

your-app
the project you already have
Let Codarc read this project
Let Codarc suggest changes to it
Allow

You choose which projects. You can take it back any time.

2

Watch it draw your app

It reads everything and lays the whole thing out as a picture — the pages people see, the places requests arrive, the parts doing the work, and where your information is kept.

Every box is one real piece of your app.
Lines run left to right, the way a request travels.

3

Say what you want different

Click the box you care about and describe the change the way you'd explain it to a friend. You never say which file, because the box already knows.

Sign in

“Lock people out after 5 wrong tries.”

Your words. Not a form, not a setting,
and never a file name.

4

Approve it, or don't

Codarc shows you what would be different in plain words before anything happens. Your live app is untouched until you say yes.

What happens today
Anyone can guess a password as many times as they like.
What happens after
After 5 wrong tries they're locked out for 15 minutes.
Approve
Not this one

Nothing reaches your live app until you say so.

What it actually does

Not just a picture of your app.

Plenty of tools will draw you a diagram. Drawing is the easy half. The question is whether you can change anything from it.

Your layout stays put

Drag the boxes wherever they make sense to you. Re-reading your app never shuffles them back.

“Make people wait 15 minutes after 5 wrong passwords.”

You say what, never where

The box you clicked is already attached to the right files.

Nothing moves without you

Every change is shown in plain words before it happens.

Your live app is never touched

Changes wait on a copy. What your customers use carries on exactly as it was until you say yes.
