Zed

Zed

Custom IDE https://zed.dev/ https://x.com/zeddotdev

Features

• open source multiplayer IDE for coding written in Rust
• there is pretty cool native “AI Agent” system that lets you connect to most third party models
• works only for real coders
• Ultra-high-performance foundation
  Zed is written from scratch in Rust and leverages both multi-core CPUs and your GPU to deliver near-instant startup, minimal typing latency, and fluid UI interactions.
• Native AI-human collaboration
  Powered by Zeta, Zed offers agentic editing where AI and developers co-edit code in real time, plus built-in chat, shared notes, and live screen/project sharing all within the same environment.
• Multibuffer editing surface
  Instead of fragmenting context across tabs, Zed’s multibuffers let you compose and edit excerpts from different files in a single, unified view—ideal for refactoring and cross-file workflows.
• First-class Git, debugging, and runtimes
  Stage, commit, diff, push, and pull directly in the editor; debug multiple languages natively; and even run inline Jupyter sessions for interactive experiments without leaving Zed.
• Open-source, extensible platform
  With thousands of contributors, hundreds of extensions, and containerized background agents via the Model Context Protocol, Zed balances community-driven innovation with enterprise-grade flexibility.

Summary

One of the most intriguing aspects of Zed is its split architecture: the local UI remains lightweight and super responsive, while the actual codebase, AI models, tests, and background agents run on remote, containerized servers. This design offloads heavy compute—enabling real-time AI-driven edits, live code execution, and multibuffer composition—without taxing your machine, all while fostering seamless collaboration between humans and AI straight out of the box.

Status: active — shipping fast, new “Delta” product. zed.dev’s current headline is Delta, “a multiplayer environment for coding with agents” (zed.dev/blog/introducing-delta). Still Rust-based, open source (GPL-3.0 w/ Apache-2.0 components), macOS/Linux/Windows; the pitch now leads with agentic parallelism (“run agents in parallel at native speed”) and human+AI collaboration over the pure-editor story.
