Show HN: Blackholes – A macOS workspace for coding agents

Andy Geek released Blackholes, an open-source macOS app for organizing coding agents, Git repositories, and terminals, supporting Claude, Codex, Gemini, and OpenCode. Built with Rust and React, it allows projects to contain multiple repositories and tasks to have their own branches and worktrees, enabling work on features across frontend and backend repos under one task. The app is available on GitHub at https://github.com/andygeek/blackholes.

Hi HN, I'm building Blackholes, an open-source macOS app for organizing coding agents, Git repositories and terminals.

A project can contain multiple repositories, and tasks can have their own branches and worktrees. For example, you can work on a feature across a frontend and backend repo, keeping both under the same task.

It supports Claude, Codex, Gemini and OpenCode, with project and task notes, file editing and Git diffs available in the workspace. The app is built with Rust and React.

Source code: https://github.com/andygeek/blackholes I'd appreciate feedback from people working with coding agents across multiple repositories, especially on what would make this fit into your existing workflow.
