Lumbridge vs Zed

A fast open-source code editor written in Rust, built for collaboration with people and AI, with agentic editing and support for external agents. Lumbridge is the open engine a company runs on when agents do the work: terminals, mail, notes, library, voice and a software factory on your own machines.

Zed

Pick Zed if you want a fast editor with agents inside it and live collaboration with teammates. It also works well next to a terminal-based stack.

Open source · GPL-3.0-or-later (Apache-2.0 components where marked)Free Personal plan; paid Pro and Business plans. Checked 2026-11-10.

Lumbridge Not released. Built from source today.

02 · Honestly

Where Zed is ahead.

  1. A full, mature code editor on macOS, Linux and Windows. Lumbridge has no code editor.
  2. Real-time collaboration: chat with teammates, code together and share a screen and project.
  3. Edit prediction from its own open-weight model, and external agents through the Agent Client Protocol.
  4. A large open-source community: its repository showed about 95 thousand stars on the day we checked.

03 · The difference

What Lumbridge adds.

  1. Core keeps agents running in the background after the window closes and lists terminals from several machines.
  2. Mobile shows and answers agents from a phone.
  3. Mail, Library and Factory are parts of the stack.
  4. Computer, Voice and Speak serve open models and speech on a GPU box you own.
