What is Bupsy?

Bupsy is a free native Mac app that hosts a team of AI bots running on a user's existing Claude Code or Codex subscription, with no accounts, credits, or external servers involved.

Bupsy is a native macOS application that hosts a small team of AI bots, each one running Claude Code or Codex under the user's own sign-in. Rather than introducing a new subscription, credit system, or hosted backend, it sits on top of the AI coding tools a developer already pays for, acting as a local control layer rather than a service of its own. The app is aimed at developers and technical teams who already rely on Claude Code or Codex and want a way to delegate ongoing work, such as fixing a broken build, drafting documentation, or triaging an inbox, without babysitting a terminal or juggling multiple chat windows. Each bot is represented by a simple animated face (eight shapes, eight colours, six moods) that communicates its state at a glance: ready, working, stuck, or waiting on a decision. In practice, bots can be given routines and goals that run on a schedule, checking in each morning or keeping a queue below a certain age. Multiple bots can share a group chat, handing off tasks to each other with @mentions while staying quiet unless addressed, which keeps usage against the underlying plan's quota efficient. Any action beyond reading requires explicit approval, and external services such as Gmail, Notion, Linear, or custom APIs are reached through a separate component called Executor that holds the credentials, which Bupsy itself never sees. Within the broader field of AI coding assistants and agent orchestration tools, Bupsy's position is narrow and specific: it does not compete with cloud-hosted multi-agent platforms that bill by credit, but instead offers a local, account-free front end for CLI tools a user already owns. It is currently Mac only, built in native Swift, and distributed as source-available software under BUSL 1.1, with iPhone, Windows, and Linux versions still in development. It is not affiliated with Anthropic or OpenAI.

How do you use Bupsy?

1Download the Mac app
Enter an email address on the homepage to start the download, then open the installer and drag Bupsy into the Applications folder.
2Sign in to an engine
Install Claude Code or Codex and sign in once through the CLI. Bupsy detects the sign-in automatically and never stores the credential itself.
3Make your first bot
Click the plus icon to create a bot, give it a name, shape, and colour, and answer its question about what job it should handle.
4Set routines and goals
Give a bot a recurring instruction, such as a morning briefing or keeping an inbox under a day old, and watch its face change as its status changes.
5Build a team
Add several bots to one chat and use @mentions to hand off tasks between them, approving any action that goes beyond simple reading.
6Connect outside tools
Link services such as Gmail, Notion, or Linear through Executor, which manages the credentials separately so Bupsy never holds the keys.

Pros and cons

Pros

Uses an existing Claude Code or Codex subscription instead of charging separately or billing by creditAI

Bots can hand off tasks to each other in group chats and still ask before anything riskyAI
Free to download for macOS 14 or later, including Apple silicon and Intel MacsAI
