Platforms & harness multiplexersWorkspaces and APIs that run several agent harnesses at once.
Platforms sit above individual agents: multi-agent IDEs that run Claude Code, Codex, and Cursor side by side in Git worktrees, or managed APIs that deploy coding agents across harnesses with sandboxes and credentials.
Systems in this category
Who it's for
Power users running many agents in parallel, and product teams that want to embed coding agents without operating the agent loops themselves.
Tradeoffs
Adds a coordination layer and another vendor. The category is young; the seed does not yet include a verified entry here.
Frequently asked
What is an agent platform?
Platforms sit above individual agents: multi-agent IDEs that run Claude Code, Codex, and Cursor side by side in Git worktrees, or managed APIs that deploy coding agents across harnesses with sandboxes and credentials.
Who should use an agent platform?
Power users running many agents in parallel, and product teams that want to embed coding agents without operating the agent loops themselves.
What are the tradeoffs of agent platforms?
Adds a coordination layer and another vendor. The category is young; the seed does not yet include a verified entry here.
Which agent platforms are in the catalog?
1 as of 2026-09-25: Cursor Origin (Anysphere).
What is an agent harness multiplexer?
A workspace or API layer that runs multiple coding-agent harnesses (Claude Code, Codex CLI, Cursor, OpenCode) in parallel — typically with worktree isolation and a shared status view.
Why are there no platform entries yet?
The first-pass inventory identified candidates but none met the verification bar for the seed. The category is kept in the taxonomy so entries land in the right place when verified.
