# Jango Jango is a macOS desktop tool for testing multi-user web applications with AI participants in separate browser sessions. Developers can assign test accounts and goals to participants, observe or direct their actions, and exercise workflows such as social interactions, messaging, collaboration, marketplaces, and sandbox order books. - Findings24: - Website: - Pricing: Freemium - Categories: Developer Tools ## What is Jango? Jango is a macOS desktop tool for development testing of multi-user web applications. It creates separate browser sessions for AI participants, each with a test account, role, and goal, so a developer can exercise interactions that normally require multiple people. Developers can observe participant screens, pause or direct activity, and join the same app with their own account. Jango is designed for apps under the developer’s control and covers workflows including social interactions, messaging, collaboration, marketplaces, and sandbox order books. ## What can Jango do? ### Separate browser sessions Each participant operates through an isolated browser session, helping represent distinct accounts rather than multiple tabs sharing one login state. ### Account, role, and goal assignment Connect a development URL and test accounts, then define roles and concrete objectives such as inviting a user, placing an order, or updating a shared task. ### Live observation and direction Watch participant screens, pause when an unexpected result occurs, issue directions, and use the app alongside the AI participants from your own account. ### Saved casts and app memory Save participant casts, encrypted login state, browser checkpoints, observed app controls, reusable hints, and execution history for subsequent development checks. ### Run evidence and comparisons Runs can leave activity, observable checks, navigation hints backed by actions, and comparisons that help document what happened across accounts. ### Dashboard, CLI, and MCP access Use the desktop workspace, launch sessions from the terminal, or give a coding assistant access through MCP. AI sessions can connect to OpenAI, Anthropic, or Vercel AI Gateway. ## Use Cases ### Social feeds and communities Exercise invitations, posts, conversations, community roles, and shared activity with multiple development accounts while checking what each account can see. ### Messaging and group chat Run multi-account chat scenarios without coordinating a group of human testers, including joining the conversation from the developer’s own account. ### Team collaboration workflows Test team invitations, shared tasks, role-based access, and other collaborative web app flows that depend on more than one participant. ### Marketplaces and sandbox order books Use buyer, seller, and other participant roles to navigate pages, submit test listings or orders, and inspect the resulting state in a sandbox environment. ### Solo regression exploration Keep a cast for repeated exploratory checks after app changes, then convert confirmed bugs into deterministic browser or API tests when precise assertions are needed. ## Frequently Asked Questions ### What does each Jango participant do? A participant operates the web app through its own browser session. Depending on the controls it can observe, it can navigate, click, fill forms, select options, upload supplied images, and perform actions described in its goal. ### Can I participate in the same test run? Yes. You can log into the app with your own account while the cast uses its assigned accounts. Jango lets you watch screens, direct participants, and pause activity. ### What do I need to set up? You need a development URL, test accounts for the participants, and a scenario with roles and goals. Jango’s Mac installer bundles Node.js and Chromium, so separate Node or Playwright installation is not required. ### Where do browsers and project data run? Browsers run on your computer. Projects, evidence, and browser checkpoints are stored in your Jango account, while AI usage can be connected to your own provider key or managed through Jango’s in-app credits. ### What types of apps may need another integration? The site identifies canvas-only apps, popup sign-in flows, and CAPTCHA as cases that may require a different integration. Jango is intended for testing apps you control. ## Quick Facts - **Product type**: AI-assisted multi-user web app testing tool - **Platform**: macOS desktop app for Apple silicon and Intel - **Primary users**: Developers testing apps that require multiple accounts or participants - **Browser model**: Separate local browser sessions for each participant - **Workflow access**: Desktop dashboard, CLI, and MCP - **AI providers**: OpenAI, Anthropic, or Vercel AI Gateway; bring-your-own key supported
