Zedium is a telemetry-free, cloud-free fork of Zed. It ships as a plain archive — there is no auto-updater and no account.
| Platform | Artifact |
|---|---|
| Linux x86_64 | zedium-<tag>-linux-x86_64.tar.gz |
| Linux aarch64 | zedium-<tag>-linux-aarch64.tar.gz |
| macOS arm64 | zedium-<tag>-macos-arm64.zip (contains Zedium.app) |
| macOS x86_64 | zedium-<tag>-macos-x86_64.zip (contains Zedium.app) |
Tags use the form v1.4.2-1 (upstream tag + fork revision).
tar xzf zedium-<tag>-linux-x86_64.tar.gz
cd zedium-<tag>
./bin/zediumTo put it on your PATH, symlink bin/zedium into ~/.local/bin/.
User data lives under XDG paths keyed to Zedium, so it never collides with an upstream Zed install:
- Config:
$XDG_CONFIG_HOME/zedium(default~/.config/zedium) - Data:
$XDG_DATA_HOME/zedium(default~/.local/share/zedium)
The app is ad-hoc signed (no Apple Developer ID). Gatekeeper will quarantine it on first launch. Remove the quarantine attribute:
unzip zedium-<tag>-macos-arm64.zip
xattr -dr com.apple.quarantine Zedium.app # -r: clear the whole bundle
open Zedium.app # or drag Zedium.app into /ApplicationsBundle identifier: dev.zedium.Zedium. User data: ~/Library/Application Support/Zedium,
config ~/.config/zedium.
Remoting works offline: the pre-compiled remote_server daemons for Linux (x86_64 +
aarch64) and macOS (arm64) ship inside the app, next to the editor binary
(Zedium.app/Contents/MacOS/remote_servers/ on macOS, bin/remote_servers/ on Linux). At
connect time the editor provisions the matching daemon onto the host — no download from the
network. See REMOTE_SERVERS.md.
There is no in-app updater. Download the newer archive and replace the binary/app bundle. Your config and data directories are preserved across versions.
- No sign-in, no telemetry, no network calls on startup.
- AI features (assistant + edit prediction) are off until you configure a provider. See
EDIT_PREDICTION.md for self-hosted edit prediction; configure chat
models under
language_modelsinsettings.json(Ollama / LM Studio / any OpenAI-compatible endpoint). - The extension registry is a static offline snapshot bundled with the release; there are no live extension updates between releases.
