01How it works
One sentence in.
A live URL out.
Four steps, the same ones you see in the app. Nothing hides behind a spinner: every change is a file you can open. How it works
01New project · composer
Describe
Say what you want in a sentence, or start from a template. Paste a screenshot if you have one. Pick React, a static site or a Node API.
02Agent panel · editor
Plan & build
The agent reads the project, writes a short plan, then edits real files with tools you can watch, from write_file to run_command. 11 tools in all, every run checkpointed.
03Split view · live preview
Preview
The project runs in its own container with a live preview beside the code. The console streams the dev server's output; fix, ask or restore from there.
preview · candle-store
04Publish dialog · checks
Publish
15 pre-publish checks run first. Then it goes live on a Codexa subdomain or your own domain, and any earlier version is one click away.
02Platform
Everything a build needs.
In one workspace.
The agent, the editor, the sandbox and publishing share one project, one history and one set of files you own.
An agent that writes real files
It lists the project, writes a plan, edits TypeScript and React with tools you can watch, and runs a typecheck before it says done.
Checkpoints
Every AI run saves a checkpoint first. Open the diff or restore the whole project in one click.
Console and logs
The dev server's output streams into the workspace while the preview reloads beside your code.
15 pre-publish checks
Secrets in code, unsafe HTML, missing titles, broken links and heavy files are caught before anything goes live.
Your code, portable
Import a repository from GitHub, push changes back, or download the whole project as a ZIP at any time.
One container per project, on Cloudflare
Generated code never runs on our web servers. Each project gets its own Container, started on demand by its own Durable Object, with React SPA, Static site, Node + Express API ready.
03Templates
111 starters that run.
11 categories.
Start from a working app instead of a blank page. Every template opens in the editor with its preview already running.
04Security & platform
Every project,
in its own box.
Codexa runs on Cloudflare: the app is a Worker, and every project gets its own Container behind its own Durable Object. Read the security overview

What does Codexa build?
Web apps you can run and publish: React SPA, Static site, Node + Express API. Describe the app in a sentence, or start from one of 111 working templates. An agent plans the change, writes real TypeScript and React files, runs a typecheck in the sandbox, and shows a live preview.
Where does my code run?
Never on our web servers. Each project gets its own container on Cloudflare, started on demand by a per-project Durable Object, and the live preview is served from a separate origin. See Security for the full request path.
Can I take my code with me?
Yes. Download the whole project as a ZIP at any time, push it to a GitHub repository, or import an existing repository from GitHub. Every AI run also creates a checkpoint you can restore.
Can I publish to my own domain?
Every plan can publish to a Codexa subdomain after the 15 pre-publish checks run. Custom domains are included on Pro (3) and Team (20). See Pricing.
How much does it cost, and can I pay in INR?
Free is $0. Pro is $20 or ₹1,499 per month, Team is $50 or ₹3,999 per month, and Enterprise is custom. Prices exclude applicable taxes. Compare plans.
Is there a desktop app?
Yes, a native app for Windows (x64) with the composer, projects, templates and settings in their own window. Download it. On other systems, Codexa runs in the browser.
