Built for everyone
Whether you code or not, #
cdbx works for you.
A real IDE.
In your browser.
Everything you'd expect from a desktop IDE — without the setup. Open a tab and start building.
- Full Monaco editor — same engine as VS Code
- Real terminal with streaming output
- AI pair programmer that reads and writes your files
- Instant preview. No npm install.
No experience
needed.
You have the idea. cdbx has the AI. Just describe what you want and watch it come to life.
- Describe what you want in plain English
- Watch your app get built in real-time
- One click to publish and share
- No setup, no installs, no learning curve
Your tools,
in context.
Connect any external service to your AI context — Notion, GitHub, Slack, Google Drive, and more. The AI queries them on demand. No copy-pasting, no tab-switching.
- Connect Notion, GitHub, Slack, Google Drive, and more
- AI queries connected services on demand — nothing preloaded
- Any MCP-compatible server works — self-hosted or third-party
- Running locally? Expose it with ngrok and connect instantly
- Connect Claude Desktop or Cursor to your experiments via the cdbx MCP server
Agents in
every step.
cdbx doesn't just have an AI chat window — agents are woven into every part of the workflow, from generating your app to fixing errors to refining your UI.
- Planning Agent — plan PRDs, architecture, and research with full connector context
- Vibe Coding generates complete apps from a plain description
- Self-Healing detects and fixes build errors without interrupting you
- Visual Loop iterates your UI against the live preview
- Help Assistant answers questions about cdbx inline as you work
Planning Agent
Think before #
you build.
A strategy partner with full access to your connected services. Write PRDs, design system architecture, plan a research report, or build a slide deck — with an AI that has actually read your Notion pages, Linear backlog, and GitHub repos.
6 plan types
General, Web App, Architecture, Deep Research, Slides, and API Spec — each with a purpose-built AI and live preview.
Connected context
The Planning Agent queries your Notion, GitHub, Google Drive, Linear, Figma, and Slack on demand.
AI-generated docs
The agent writes directly to your plan's file tree. /PRD, /ADR, /RFC, and more as slash commands.
"Start Building" handoff
When your plan is done, one click opens a new experiment pre-loaded with your plan as context.

Your framework.
Frontend or backend, scripted or compiled — cdbx runs it all in one place.

Runner API
Execute code from anywhere. #
Send code, get output. No infrastructure, no Docker, no cold starts. A single API call runs your code in a secure sandbox and returns stdout, stderr, and exit code in milliseconds.
curl -X POST https://api.cdbx.ai/v1/runner/execute \
-H "Authorization: Bearer cdbx_your_key" \
-H "Content-Type: application/json" \
-d '{
"language": "python",
"files": { "main.py": "print('Hello!')" },
"entrypoint": "main.py"
}' | jq
30 languages, one endpoint
Python, Go, Node, Rust, Java, C, C++, Swift, Haskell, Elixir, Zig, and 19 more — all running in isolated sandboxes.
Secure by default
Network isolation, memory caps, PID limits, seccomp profiles. Each execution runs in a fresh container.
Built for agents
Your AI agent can run code it generates. The cdbx MCP server exposes run_code as a tool — Claude can call it directly.
Simple billing
Free tier includes 100 executions/month. Pro includes 2,000. Buy top-up packs when you need more — they never expire.
