Jango

Jango is a Mac tool for checking features that involve several people at once. Developers give AI participants separate test accounts and goals, such as a buyer placing an order or a teammate updating a task, and each participant acts through its own isolated browser.

Features

• Participant setup: assigns each AI participant a role, a goal and its own test login against a development address.
• Live control: lets the developer watch the participants, direct them, inspect their screens or join in.
• Memory between runs: keeps identities, encrypted login state, navigation hints backed by actions that worked, and run evidence, so a cast can return after a change.
• Several ways to run: works from the desktop app, a command line or a coding assistant connected over MCP.
• Account storage: saves apps and progress in the user's account so a cast can be reused.

Customers and markets

Developers testing multi-user features such as social feeds, marketplaces, sandbox order books and collaborative workflows.
