Product
An AI-native development platform, end to end.
Prompt-to-app generation, a real editor, isolated runtimes, databases, GitHub, and deployment in one workspace. Built so the generated code stays yours.
Four things Codexa does
Every project moves through the same loop. You can enter at any point: start from a prompt, a template, or an imported GitHub repository.
- Generate Describe an app and get a real project from a starter template, with a plan you can read before the agent edits anything.
- Edit A Monaco editor with tabs, explorer, search and replace, diagnostics, diff view, autosave, and keyboard shortcuts.
- Run Preview in an isolated sandbox through a host-based proxy, with streamed logs and responsive viewport controls.
- Ship Deploy to Codexa static hosting with history and rollback, or to Vercel when a token is configured.
The workspace
Editor, agent, preview, and logs side by side.
How the agent works
Step 1: Plan
The agent reads your prompt and the project files, then writes a short plan of the files it will create or change.
Step 2: Generate
It edits real files with tools (read, write, rename, delete). Every change is recorded, and a snapshot is taken first.
Step 3: Validate
Type-check, build, and tests run in an isolated sandbox. Errors are read back and repaired, bounded to two attempts.
Step 4: Run
Start a preview in the sandbox with streamed logs, viewport controls, and a share link.
Step 5: Ship
Deploy to Codexa static hosting or Vercel, keep deployment history, and roll back in one click.
Requires an AI provider
Everything included
AI app builder
Describe an application and get a real project: files, dependencies, and a running preview.
AI agent
Plans, edits files, runs builds, reads errors, and performs bounded repairs. Build, Ask, and Fix modes.
Code editor
Monaco-based editor with tabs, explorer, search and replace, diagnostics, diff view, and autosave.
Isolated runtimes
Projects run as an unprivileged user in Linux namespaces with memory and process limits.
Live preview
A host-based proxy serves your running app with desktop, tablet, and phone viewports.
Snapshots and diffs
Named checkpoints with per-file diffs and one-click restore. A snapshot precedes every AI run.
Databases
PostgreSQL and Supabase connections with a schema browser and a SQL runner that confirms destructive statements.
GitHub
Sign in, import repositories, commit and push from the workspace when OAuth is configured.
Deployment
Codexa static hosting with history and rollback; Vercel adapter when a token is provided.
Environment variables
Encrypted at rest, masked in the UI, injected into previews and deployments.
Teams
Workspaces with owner, admin, editor, and viewer roles plus email invitations.
INR and USD billing
Razorpay for India, Stripe internationally, monthly or annual. Limits enforced server-side.
Frequently asked questions
Do I own the code?
Yes. Projects are ordinary files stored in your workspace. You can download them, push them to GitHub, or deploy elsewhere at any time.
Which stacks are supported today?
Starter templates cover React + Vite + TypeScript + Tailwind single-page apps, static HTML/CSS/JS sites, and Node + Express REST APIs. You can import other repositories from GitHub, but the sandbox is tuned for these three.
Does the AI work out of the box?
Only when the operator of the Codexa instance has configured an Anthropic or OpenAI API key. Without one, AI features show a "not configured" state. Everything else (editor, runtime, deployment) works without AI.
What happens when the AI makes a mistake?
A snapshot is taken before every run, each run records its plan, tool calls, and changed files, and you can revert the run with one click. Validation (type-check, build, tests) runs in the sandbox and the agent repairs errors at most twice before handing control back.
Where does my code run?
Never inside the web application. A separate runner service executes projects as an unprivileged user inside Linux namespaces with cgroup memory and process limits and timeouts. Docker and E2B drivers are available for operators who prefer them.
Can my team edit the same file at the same time?
Not yet. Realtime presence shows who is viewing which file, and snapshots make it easy to merge work, but concurrent editing (CRDT) is on the roadmap.
How do you charge?
Free, Pro, Team, and Enterprise plans in INR or USD, monthly or annual. Limits (AI requests and tokens, runtime minutes, deployments, storage, projects, members) are enforced on the server. See pricing.
