Zed's Parallel Agents: Multiple AIs, One Editor Window

Zed just shipped Parallel Agents. Multiple AI agents, running at the same time, in one editor window.

The Threads Sidebar groups agent threads by project. Mix different agents per thread, or span multiple repos with one. Worktree isolation is there when you need it. It's open-source, runs at Zed's standard 120 fps, and works with whichever agents you choose. Available on macOS, Linux, and Windows.

The layout got a refresh too. Agent panels and threads dock left by default; project and git panels sit right. Existing users can opt in.

"We won't lie, it drove us a little crazy," Mikayla Maki and Richard Feldman wrote in the announcement. The team spent days testing with hundreds of agents before shipping.

Zed co-founder Nathan Sobo coined "agentic engineering" in 2025 for this idea of combining human craftsmanship with AI. Parallel Agents fits that philosophy. Not fully vibe-coded. Not AI-disabled. A middle path.

Cursor still focuses on single-agent interactions. VS Code's Copilot lacks native multi-thread management. Zed is betting developers want several agents running at once. Right now, nobody else does this as cleanly.
