OpenCode native CLI preview builds

The OpenCode native CLI, opencode-native, is a Rust client for OpenCode, built from its oc-rust branch. Each build is an unsigned prerelease for Linux x64, Linux arm64, macOS arm64, and Windows x64, for testers.

Startup and memory

Watch as video (MP4, 1080p).

The client alone, against a TypeScript server that is already running (median of 8 runs):

	opencode 2.2.7	opencode-native 0.0.0-rs-2
time to first frame	118 ms	5.8 ms
client peak memory, 20 prompts	319 MB	44 MB
client CPU time, 20 prompts	3.92 s	0.17 s

The client starts its own server (--standalone):

	opencode 2.2.7	opencode-native 0.0.0-rs-2
time to first frame	314 ms	219 ms
client + server peak memory	604 MB	410 MB
client + server CPU time, 20 prompts	6.93 s	2.79 s

opencode-native replaces only the client: the TypeScript server holds 374 of its 410 MB. The method, raw data, and machine (AMD Ryzen 7 9800X3D, Linux) are in docs/benchmark.md.

How it works

opencode-native uses OpenTUI's Rust bindings, which drive the same native library as the TypeScript CLI's @opentui/core. So the screens, keys, and themes match, and a parity harness compares the two clients. It talks to the same TypeScript server: it finds or starts the background service, --server <url> attaches to one, and --standalone starts a private one. Sessions and cli.json are shared.

What differs:

• Server plugins run in the TypeScript server and work as before.
• TypeScript TUI plugins do not run; /plugins lists them as skipped.
• Native TUI plugins (.so, .dylib) load instead: see the quick start.
• opencode-native upgrade does not update a preview build; re-run the install script.
• There is no /restart; use opencode-native service restart.
• HTTPS trusts the system's root certificates; NODE_EXTRA_CA_CERTS is ignored.
• 14 languages are syntax-highlighted; others show as plain text.

The full list is in parity/deviations.

Install

curl -fsSL https://raw.githubusercontent.com/simonklee/opencode-native-preview/main/install.sh | bash

This checks the newest build against SHA256SUMS and installs it to ~/.local/bin/opencode-native (or $OPENCODE_NATIVE_INSTALL_DIR). Run it again to update. Linux builds need glibc 2.35 or newer. To verify an archive's build attestation: gh attestation verify opencode-native-<version>-<target>.tar.gz --repo simonklee/opencode-native-preview.

On Debian and Ubuntu, download the .deb from the latest release and run sudo apt install ./opencode-native_*.deb.

Requirements

Install the TypeScript CLI, 2.2.7 or newer, on PATH (or set OPENCODE_TS_BIN to it): npm i -g @opencode/cli. To keep the client's tabs apart from opencode's, set OPENCODE_TUI_CHANNEL=native-preview.

macOS

The binary has only an ad-hoc signature. If you downloaded an archive with a browser, run xattr -d com.apple.quarantine opencode-native.

Windows

Download opencode-native-<version>-x86_64-pc-windows-msvc.zip from the latest release and extract it; keep opentui.dll next to opencode-native.exe. If Windows blocks the download, run Unblock-File on the zip before extracting. Install the TypeScript CLI with npm i -g @opencode/cli. Each build is tested on GitHub's Windows Server 2025 runner, with the TUI on a pseudoconsole (ConPTY); no other terminal is tested.

Reporting bugs

Include the output of opencode-native --version and the end of ~/.local/share/opencode/log/opencode.log.
