The free, open-source Superset alternative

Both run Claude Code, Codex, and other coding agents in parallel on your repo. bb is free for any team size and open source, while Superset charges $20 per user a month for teams. bb includes phone and browser access, remote machines, and automations at no cost, and runs natively on Windows. When one agent starts another, the new agent gets its own thread (one conversation with one agent) that you can open and message.

A small, venture-backed team that most recently worked together at Figma, building Figma’s plugin platform. The team also includes alumni of Meta, Quora, and Mapbox.

bb is developed in the open: the core team commits to it every day, dozens of community contributors send changes each month, and a new release ships every week. Follow along or reach the team on GitHub and Discord.

Yes: bb. It’s free for any team size and MIT-licensed, so you can use and change it for anything, including at work. Superset charges $20 per user a month for teams, and its Elastic License 2.0 makes the code public but isn’t an open-source license. Download bb.

1. Download bb for macOS (Apple Silicon), Windows, or Linux (alpha). On an Intel Mac, run npx bb-app@latest, which needs Node.js 22.19 or later.
2. Install and sign in to a coding agent, like Claude Code, Codex, Cursor, or OpenCode.
3. Open bb, add your project folder, and type your first request.

Ask bb to do it. Your repo and Superset’s worktrees are plain Git on your machine, so a bb agent can add the repo and open each unfinished worktree as a thread. Superset keeps working while you try bb.

Yes. bb works out of the box, with worktrees, diff review, automations, and the mobile app ready from your first thread. When you want more, install plugins from the marketplace or ask an agent to build one. Plugins can add panels, commands, and new agents, and they work in the mobile app too. Everything in the app is also in the bb CLI and HTTP API, so scripts and other agents can start, message, and manage threads.

Yes, without leaving the thread. Select lines in its diff and choose Add to chat to send feedback. Once the agent opens a pull request, the thread shows its checks and a Merge button. The GitHub plugin adds Review with agent to any PR.

Yes, free. Automations start an agent thread or run a script on a repeating schedule, once at a set time, or after a delay. Superset’s automations only repeat and need Pro. Pick the agent, model, and permission mode, and give each run its own worktree if you like.

Yes, for one person or a whole team. The mobile app, remote machines, automations, and plugins are all included, while Superset puts its mobile app, remote machines, and automations on its $20-per-user Pro plan. You pay only for the agent plans or API keys you already use, from any provider. The code is on GitHub under the MIT license.

Yes. bb runs the agents you already use, signed in the way you already pay for them: a Claude Pro or Max plan, a ChatGPT plan for Codex, a Cursor plan, API keys, or any other provider’s plan. Your existing setup comes along too (CLAUDE.md, skills, MCP servers, and agent settings).

Yes, with Account Pooler, an experimental plugin built into bb. Turn it on and add the Claude Code and Codex accounts you own. When one account hits its limit, bb moves the thread’s requests to the next one, so it keeps running. Superset can hold several accounts, but you pick the default yourself, and a running agent keeps its account until you relaunch it.

Claude Code, Codex, Cursor, and OpenCode, plus Pi, Grok Build, omp, and Hermes Agent. In Settings, add any other agent that supports the Agent Client Protocol (ACP), an open standard for connecting coding agents to apps, like Gemini CLI or Devin. You can also add one with a plugin. Each thread can use a different agent.

Yes. Ask Claude Code to “start a bb Codex thread to review this branch, then fix what it finds.” It starts Codex in the same worktree, waits, and applies the fixes. Codex shows up as its own thread, so you can read the exact prompt Claude sent, watch it work, and message it mid-run. Any other pair works the same way, like Cursor and OpenCode.

Yes, and there’s no coordinator to set up; Superset does this through a coordinator skill. Tell your agents to work together and they coordinate on their own: any agent can message another thread, whatever the provider, agents answer each other’s messages, and an agent hears back automatically when a thread it started finishes or fails. The receiving thread shows each message and who sent it, and you can step in and message any of them yourself.

Yes. Give each thread its own Git worktree so agents don’t overwrite each other’s changes. List your .env files and setup commands once, and bb prepares every new worktree. By default, bb runs one thread per processor core and starts the rest as others finish.

Yes. Pick a permission mode for each thread. Accept Edits applies changes inside the project and asks before anything else. Approve for me reviews requests automatically and sends high-risk ones to you. Full Access skips approvals and can run anything on your machine. Allow or deny approvals from your computer or your phone.

Yes, for free. Use the bb mobile app, a public beta on iPhone through TestFlight (Apple’s beta testing app) and in alpha on Android, or open bb in any browser through bb Connect, bb’s free remote access. Superset’s iPhone app needs Pro and iOS 26, its Android app is a waitlist, and it has no browser access.

Not on that laptop. Agents run on your machine, and closing the lid puts it to sleep. On a Mac, switch on Keep Awake, a built-in bb plugin that stops idle sleep while bb runs. For long runs, add an always-on desktop or server to bb, or run threads in the cloud with a cloud plugin like Modal Sandbox, which is built in (experimental) and starts each thread in an on-demand sandbox in your own Modal account.

Yes. Download the app for Apple Silicon Macs, Windows, or Linux (alpha), or run npx bb-app@latest on an Intel Mac. Superset doesn’t run on Windows yet.

Yes: bb runs on your machines, so your code goes only where your agents send it, the AI providers you chose. Anonymous usage stats exclude code and prompts and can be turned off. The bb Connect relay doesn’t store traffic, but isn’t end-to-end encrypted.

Yes, free at any team size, while Superset charges $20 per user a month for teams. Each person runs bb on their own machines with their own agent subscriptions and shares work through Git and pull requests as usual. bb doesn’t offer team plans, SSO, or a support SLA.
