# zed

a sourced history of zed industries, the editor company founded by atom and tree-sitter veterans, from gpui to its idea of a fast collaborative editor.

zed industries is the atom team building the editor atom could not be — rust instead of electron, gpu-rendered instead of webview, collaboration in the foundation instead of a plugin. nathan sobo, max brunsfeld, and antonio scandurra spent the 2010s on atom, teletype, and tree-sitter, lost the xray rewrite when microsoft bought github, and started over in an empty repo. this is the record of the second attempt — the macos-only beta, the open-source conversion, the agent pivot and its backlash, and the turn toward deltadb and delta, where the company is betting the pull request itself.

- [history](https://hraness.com/zed/history): the company, sourced and dated — atom's rise and sunset, the xray rehearsal, the empty-repo restart, and the agent-era turn toward delta.
  - [the atom years](https://hraness.com/zed/history#atom): 2013–2022 — tree-sitter, teletype, and xray inside github; memo, the operation-based vcs that waited eight years to ship.
  - [the restart](https://hraness.com/zed/history#founding): 2019–2023 — the empty-repo restart, the warp detour, the seed, the dogfood year, and a macos-only beta with $10m from redpoint.
  - [the open-source year](https://hraness.com/zed/history#open-source): 2024 — the gpl relicensing, the 1,576-point thread, linux, wasm extensions, ssh remoting, and zed ai.
  - [the agent era](https://hraness.com/zed/history#agents): 2025 — zeta, the agent panel, acp with google, disable_ai, zedless, sequoia's $32m, and windows at last.
