Orca: app and UI for Hermes Agent

Desktop and mobile workspace for running parallel coding agents, including Hermes Agent, in git worktrees

What Orca does

Orca is a desktop application, with an iOS and Android companion, for running many terminal-based coding agents at once. Each agent gets an isolated git worktree, so one prompt can be fanned out to several agents and the results compared before the best one is merged. The app adds terminal splits, an editor where files and images can be dragged into an agent prompt, and in-app browsing of GitHub and Linear pull requests, issues and project boards.

Orca works with any CLI agent that runs in a terminal. Its README lists Hermes Agent among dozens of supported agents, alongside Claude Code, Codex, OpenCode and Pi. Other features include SSH worktrees for running agents on a remote machine, comments on AI-generated diffs that are sent back to the agent, a Design Mode that passes a clicked page element's HTML and CSS into a prompt, and an Orca CLI that agents can use to script the app themselves.
