AI Agents<br>Agents in<br>every step.<br>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.<br>Planning Agent — plan PRDs, architecture, and research with full connector context<br>Vibe Coding generates complete apps from a plain description<br>Self-Healing detects and fixes build errors without interrupting you<br>Visual Loop iterates your UI against the live preview<br>Help Assistant answers questions about cdbx inline as you work
Planning Agent<br>Think before you build.<br>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<br>General, Web App, Architecture, Deep Research, Slides, and API Spec — each with a purpose-built AI and live preview.
Connected context<br>The Planning Agent queries your Notion, GitHub, Google Drive, Linear, Figma, and Slack on demand.
AI-generated docs<br>The agent writes directly to your plan's file tree. /PRD, /ADR, /RFC, and more as slash commands.
"Start Building" handoff<br>When your plan is done, one click opens a new experiment pre-loaded with your plan as context.

Runner API<br>Execute code from anywhere.<br>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<br>Python, Go, Node, Rust, Java, C, C++, Swift, Haskell, Elixir, Zig, and 19 more — all running in isolated sandboxes.
Secure by default<br>Network isolation, memory caps, PID limits, seccomp profiles. Each execution runs in a fresh container.
Built for agents<br>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<br>Free tier includes 100 executions/month. Pro includes 2,000. Buy top-up packs when you need more — they never expire.
