## Summary
- Qualify OpenCode **2.1.4** (latest stable, 23 October) with the
existing locked **2.1.0 client/plugin** dependencies, and **recommend**
it.
- Keep the technical **minimum at 2.1.2**: no consumed contract changed,
so the minimum has no new reason to move.
- 2.1.2 and 2.1.3 daemons stay ready and get an optional upgrade offer.
2.1.4 is the `tested` version. Newer and custom labels keep
authenticated contract recognition.
- The reviewed-contract fast path lists the 2.1.2 minimum and the 2.1.4
target.
- The recommended version is updated in the help (all ten locales), both
READMEs, `CONTRIBUTING.md`, `dev-docs/OPENCODE_COMPATIBILITY.md` and the
architecture skill.
## Contract review (v2.1.3 → v2.1.4, 72 commits)
- **Authenticated OpenAPI:** 121 → **124 paths**, 146 → **149
operations**. No operation changed. The changes:
- added `POST /api/experimental/client-mcp/token`;
- added `GET /api/experimental/client-mcp` (WebSocket);
- added `POST /api/debug/heap-dump`;
- `Config.InfoEncoded` gains the opt-in
`experimental.background_compaction`.
The session event (`V2EventEncoded`) and message schemas are unchanged.
None of the new routes is on the instance proxy allowlist, and the proxy
relays WebSockets only for SideCars and previews.
- **Published declarations:**
- the client adds `mcp.client.token` and `debug.heapDump`;
- the schema and plugin changes are type refactors and unused-export
removals, among them `SessionID.descending`, `SessionEvent.Source` and
`PromptInput.FileAttachment.create`; `Session.Message.ID.fromEvent` now
takes any string instead of an event ID. CodeNomad uses none of these,
and every host module its native plugin bundles import
(`@opencode/plugin`, `/effect`, `/promise/adapter`, `/rpc`,
`@opencode/schema/location`, `/session`) still exists.
- **MCP elicitation forms**
([#58184](https://github.com/anomalyco/opencode/pull/58184)): an MCP
server asking for input during a tool call now creates a global-session
Form whose `form.created` event carries the server's location.
CodeNomad's live path requires that location for global Forms and shows
them as a **Project request**. Review found that the live path dropped
the location from the queued Form, so its reply lacked
`x-opencode-directory` and failed for a worktree or subdirectory until a
pending-request rescan. **#1127** fixes that; recovery already kept it.
A native probe (minimal stdio MCP server, a real Code Mode `execute`
call, CodeNomad-style reply) gives:
| Runtime | Form listed for the location | `form.created` carries the
location | Reply completes the tool |
| --- | --- | --- | --- |
| 2.1.3 | yes | **no** | yes |
| 2.1.4 | yes | **yes** | yes (`action: accept`, `channel: stable`) |
On 2.1.3 such a request only appeared after a pending-request rescan; on
2.1.4 it appears live. The probe sends the location header itself, so it
checks the runtime contract; #1127 covers CodeNomad's live reply path.
- **Other changes** are covered by the native suites below:
- compaction (oldest-first shortening, ignored buffers, overflow
detection);
- the agent's model for sessions without one;
- V2 agent files;
- V1 global-session import attribution;
- MCP lifecycle fixes.
- **Live check:** this machine's shared daemon runs 2.1.4, and the
CodeNomad desktop session works through it.
## Isolated Windows qualification
Base: dev `9ac792fff`; Node **24.20.0**; exact official CLI **2.1.4**;
unchanged locked client/plugin **2.1.0**.
- **Build and checks:** production server/UI/native plugin builds,
server and root typechecks, native bundle guard.
- **Native runtime (9/9):**
- Code Mode job ordering, plugin runtime, automation;
- complete pruning, history, ownership, worktree and event relay;
- loaded-only pending snapshot;
- Missions contract, family control, native and Compare/Wayfinder
trajectory.
- **Sessions (15/15):** environment, fork, aside, interrupt, lifecycle,
blank cleanup, prompt skills, provider usage/accounts/selection, service
usage, web search, plugin packages, output limit, Promise-tool failure.
- **Recurring (5/5):** all **11 recurring Mission journeys**, subagent
depth, **2 MiB** compaction, permission receipts.
- **Migrations (10/10):**
- history from **2.0.3, beta-19271, 2.0.32, 2.1.0, 2.1.1, 2.1.2 and
2.1.3** to 2.1.4;
- Git degraded/init;
- temporary workspaces.
- **Installation (3/3), with the 2.1.4 recommendation:**
- fresh install of the 2.1.2 minimum;
- native **2.0.15 → 2.1.4** upgrade, after which the already-running
daemon keeps its PID and 2.0.15 version;
- explicit OpenCode **1.18.10 → 2.1.4** replacement.
- **After the recommendation change:**
- admission, transport, update, installation and instance proxy units
**116 passed, 1 POSIX-only skipped**;
- full server **2,471 passed, 8 skipped**, no failure or cancellation;
- UI units **1,699/1,699**;
- focused browser **126/126**;
- native pruning with the real rendered UI;
- the exact CI invocation of the Code Mode regression (without tsx);
- ten-locale help checks (**9/9**).
This is Windows automation evidence. In CI, `latest` resolves to 2.1.4:
the compatibility job runs the native suites against the minimum and
latest on Windows, and the migration and Git-degraded certification runs
them on Ubuntu, Windows and macOS. WSL, packaged desktop,
installers/updater end-to-end and real mobile devices keep their
separate release gates.

Install CodeNomad
Choose a local desktop host or run the standalone server. In both cases, OpenCode owns the shared native service and history.
Desktop downloads
- Open the latest release.
- Choose the build matching your operating system and processor.
- Extract the ZIP or install/run the platform package, then launch CodeNomad.
| Platform | Electron release | Tauri release | Platform notes |
|---|---|---|---|
| macOS | ZIP, Intel or Apple Silicon | ZIP, Intel or Apple Silicon | macOS 13.5 or later is required by the bundled runtime. |
| Windows | ZIP, x64 | Installer, x64 | Windows 10 or later; Tauri uses WebView2. |
| Linux | Debian package, x64 | AppImage, x64 | Built and tested on Ubuntu 24.04; compatibility with older distributions is not guaranteed. |
Desktop releases include the runtime resources needed by the backend and OpenCode installer, so you do not need a separate Node.js/npm installation to use them. Git is not bundled. Native browser automation is supported in Electron and Windows Tauri; other Tauri platforms use iframe previews.
For a verified download blocked at launch, see platform troubleshooting. Never run an untrusted archive merely to bypass a warning.
Install on Linux
From the folder containing your downloaded release, substitute its actual version and filename:
sudo apt install ./CodeNomad-Electron-linux-x64-<version>.deb
For the Tauri AppImage:
chmod +x CodeNomad-Tauri-linux-x64-<version>.AppImage
./CodeNomad-Tauri-linux-x64-<version>.AppImage
If FUSE is unavailable, use the AppImage's extraction-and-run mode:
./CodeNomad-Tauri-linux-x64-<version>.AppImage --appimage-extract-and-run
The Electron Debian installation configures Chromium's sandbox. Do not disable the sandbox as an installation workaround. Linux Tauri graphics issues have a targeted WebKit workaround.
Requirements
| Requirement | Where it must be available | Current requirement |
|---|---|---|
| OpenCode CLI | Selected execution host, including the selected WSL distribution where applicable | Minimum 2.1.2; 2.1.4 is the recommended/qualified target. Newer or custom versions undergo contract validation rather than an untested-version ban. |
| Git | CodeNomad backend account's PATH |
Required for repository identity, Git operations and worktrees. |
| Node.js/npm | Standalone-server and source-build host | Node.js 24 LTS; reproducible source builds use .node-version (24.20.0). Bundled with desktop runtime/installation resources. |
| Workspace folder | Backend-accessible disk | An explicitly opened physical folder, not a device-local folder inferred by a remote browser. |
On Windows, install Git for Windows with command-line/third-party access enabled. A user-writable, per-user installation is sufficient. On macOS/Linux, use Git's platform instructions.
After changing PATH, fully quit and relaunch the desktop app, or restart the standalone backend under the intended account. Reloading a browser does not update the backend environment. Git available only inside WSL does not satisfy a Windows backend's Git requirement.
Without Git, you can still open a physical folder and use directory-only conversations, including asking the agent for installation help. Repository/worktree operations remain unavailable; session access stays limited to that exact folder. CodeNomad tells the agent about backend Git availability before prompts/custom commands and removes that advisory after recovery. The agent's execution host can differ from the backend host, so install Git for the backend, not only for the agent's shell.
Select OpenCode on first launch
- In setup, choose a compatible existing executable or use the offered OpenCode installation action.
- Verify the runtime status before opening a project.
- Revisit Preferences → OpenCode to manage the executable, installation and shared service separately.
CodeNomad prefers compatible executables on PATH and supports an explicitly selected executable. If PATH starts an older OpenCode, setup offers to replace an npm-installed OpenCode 1.x after confirmation, or to install OpenCode 2 for CodeNomad beside an installation made another way, which it never modifies; see OpenCode setup. Installing/updating a CLI does not silently restart an already running shared service. See OpenCode setup for restart/reload consequences, WSL and session environment.
Use a browser instead
Install Node.js/npm, Git and OpenCode on the server host, then use the server launch procedures. Connect with the printed address, configured authentication and a trusted certificate. A browser/PWA needs a live backend; it is not an offline copy of your projects.
For ports, bindings and TLS, use direct access. To pair a device without opening inbound ports, use Remote Control. For development and packaging commands, see source builds.
