You describe it. cdbx builds it.

Built for everyone
Everything you'd expect from a desktop IDE — without the setup. Open a tab and start building.
You have the idea. cdbx has the AI. Just describe what you want and watch it come to life.
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.
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
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.

Runner API
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.

# }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.
