Built for everyone

Whether you code or not, cdbx works for you.

For developers

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.
  • Models from Anthropic, OpenAI, Moonshot, or xAI — bring your own key or use ours
For makers & creators

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
MCP Connectors

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, ChatGPT, Grok, Claude Code, or Cursor to your apps via the cdbx MCP server
AI Agents

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. And they're not just for building: Agents handle tasks on your behalf even if you never open the editor at all.

  • 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
  • Agents act on your behalf across Slack, GitHub, Linear, and more — no app, no code required

Planning Agent

Think before you build. Or not.

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.

Planning is there when you want it — never required. You can also just start typing and get building immediately.

  • 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 starts building — the app carries your plan with it as context.

Design Systems

It builds in your design language.

Most AI picks its own taste and you spend the session correcting it. Give cdbx a design system and it builds against that instead — the right colours, the right corner radius, the components you actually have.

Bring a built-in one, your Figma tokens, or your own component library over MCP.

  • Tokens, not pasted colours

    Your palette becomes real CSS variables in your app, and the AI styles with them — so nothing is hardcoded and everything stays changeable.

  • Switch and the app follows

    Change design system and the whole app re-themes. No find-and-replace, no rewrite.

  • Checked after every change

    A hardcoded colour that one of your tokens already covers is caught and corrected automatically, before you ever see it.

  • It asks instead of guessing

    The AI looks up a component’s real props the first time it uses one, rather than inventing a prop that does not exist.

How design systems work

Simple by design

From idea to live app in minutes.

No install, no config, no deploy step. Describe what you want and it is running in your browser — not a preview of an app, the actual app.

When it outgrows the browser, cdbx moves it onto a real server mid-build and keeps everything it had. You never pick a runtime.

  • 01

    Describe

    Tell cdbx what you want to build in plain English, or pick a template.

  • 02

    Build

    AI generates all your files instantly. Your app runs in the browser immediately.

  • 03

    Ship

    One click to publish. Share your live app with anyone in the world.

Every stack

Your language. Your framework.

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

Code Execution 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
curl -X POST https://cdbx.ai/api/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

# {
#   "stdout": "Hello!\n",
#   "exitCode": 0,
#   "durationMs": 94
# }

  • 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, ChatGPT, or Grok 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.

Agents

Early access

It keeps working after you stop.

An Agent for everything — your inbox, your tools, and the app you shipped last week. Talk to one directly, or set it loose on a schedule.

Automate the boring stuff

Add skills to organise trips, emails, and reminders.

Give an agent a goal, choose the ready-made skills it needs — like organising a trip itinerary or filtering sales pitches — and pick exactly which cdbx connections it can use. You share specific Slack channels, Sentry projects or Notion pages one by one, without handing over your main passwords.

  • Add ready-to-use skills for everyday tasks
  • Choose exactly what each agent can see and do
  • No shared master passwords or risky access

Build the app. Let agents run it.

Deploy agents natively into your custom cdbx.ai apps.

Agents that live inside your shipped apps with direct access to that app's own data and schema. Let them handle database mutations, answer users in a chat widget, or read your code to make updates.

  • Reads your app's files and how its database is set up
  • You pick each permission separately, never in a bundle
  • It never publishes or changes your database on its own

Set it once. Then forget it.

Put routine jobs on a schedule, or on a trigger.

Give your agent a time — every Monday morning, say — or an event to watch for, like a new signup or an email. It wakes up, does the job, and logs what it did. If it hits an action it can't take back, it pauses and waits for your okay.

  • Runs automatically on daily or weekly schedules
  • Wakes up instantly on new activity or app errors
  • Strict spending limits prevent budget surprises
  • Stops and asks permission before major changes
