Launch a disposable hexgate sandbox in your browser: define an agent in a notebook, then chat with it in the dashboard Playground and watch policy decisions stream. It’s throwaway — everything vanishes when you’re done.

▶ Launch the live demo

Opens your own isolated sandbox — no install, no login. Bring your OpenAI key.
Bring your own key (BYOK). You paste your own OpenAI key into the notebook — it stays in your throwaway sandbox and is never logged.

​
What you do

1

Define your tools + agent

In the notebook, write your tools (@tool) and the agent (create_agent(...)) as real Python.
2

Add your key & start

Paste your OpenAI key and click Start — the agent goes live.
3

Open the Playground & chat

Click Open the playground — send a message and watch reasoning, tool calls, and policy decisions (allow / deny / approval) stream live. Edit the policy in the Policies tab and the next message picks it up.

​
Run it locally

Open http://localhost:2718, define your agent, add your key, click Start, then open the Playground.
