Features

  • Tray-based — Runs in the system tray, no browser needed
  • Live usage data — Rolling, weekly, monthly quota at a glance
  • Multi-account support — Add and switch between multiple OpenCode accounts
  • Custom glass account menu — iOS-style popover menu, no native <select>
  • API Key management — List, copy, and manage API Keys in an overlay panel
  • Manual cookie login — Sign in via your browser once, paste the auth cookie
  • Auto-hide to tray — Close button minimizes to tray
  • Configurable workspace — Switch between workspaces from the UI
  • Chinese i18n — Full Chinese localization for all UI text
  • Lightweight — ~60MB packaged, no background services

Install

Download

Download the latest installer from Releases.

Build from source

npm install
npm run build:win # Windows NSIS installer

Usage

First-time setup

  1. Launch the app. Click Login.
  2. Click Open OpenCode — this opens https://opencode.ai/workspace/<id>/go in your browser.
  3. Sign in with your account (Google OAuth).
  4. Press F12 → Application tab → Cookies → https://opencode.ai.
  5. Find the cookie named auth, copy its Value (starts with Fe26.2**...).
  6. Paste the value into the app's login panel and click Save Cookie.

Your workspace ID is auto-detected. If you need to switch workspaces, edit the Workspace ID field in the login panel and click Save Account.

Multiple accounts

  1. Click New in the footer to open a blank account editor.
  2. Enter a name, workspace ID, and paste the auth cookie.
  3. Click Save Cookie — a new account is created and becomes active.
  4. Use the account menu button (left of status pill) to switch between accounts.

API Keys

  1. Click Keys button (right of account menu) to open the API Key overlay.
  2. View masked keys in the list. Click Copy to copy a key to clipboard (main process, never exposed to renderer).
  3. Create/Delete are disabled until the POST seroval encoding is verified.

Daily use

  • Refresh — Click the Refresh button or right-click the tray icon → Refresh Usage
  • Hide to tray — Click × or close the window
  • Open config folder — Click Config to find config.json

Configuration

Configuration is stored at %APPDATA%\opencode-go\config.json (v1.1.0 multi-account format):

{
"activeAccountId": "acc_20260531_ab12cd34",
"accounts": [
{
"id": "acc_20260531_ab12cd34",
"name": "Main",
"workspaceId": "wrk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"auth": "Fe26.2**...",
"createdAt": "2026-05-31T00:00:00.000Z",
"updatedAt": "2026-05-31T00:00:00.000Z"
}
]
}

Legacy single-account config ({ "auth": "...", "workspace_id": "..." }) is auto-migrated on first launch.

You can also set environment variables:

set OPENCODE_AUTH=Fe26.2**...
set OPENCODE_WORKSPACE_ID=wrk_...

CLI Tools

The scripts/ directory contains standalone CLI tools (Node.js 18+):

# Fetch usage from command line
node scripts/fetch-usage-cli.js
# Pass auth as argument
node scripts/fetch-usage-cli.js "Fe26.2**..." [workspace-id]
# Verify runtime config and accounts
npm run check:accounts
# Verify runtime usage fetch
npm run check:usage:runtime
# List API Keys for active account
npm run check:api-keys

How It Works

OpenCode uses a custom seroval-based API protocol over standard HTTP. The app:

  1. Sends a GET /_server request with the function hash and seroval-encoded arguments
  2. Parses the seroval response to extract usage summaries and details
  3. Displays the data in the glass-morphism UI

No browser automation, no Puppeteer, no headless Chrome.

Security

  • Full auth cookies and API Keys are owned by the Electron main process
  • Renderer only receives masked previews (Fe26.2**...xxxx, sk-...xxxx)
  • API Key copy is a one-shot main-process clipboard action
  • No full secrets are logged or persisted in the UI
  • New account flow never allows deleting the active account

OpenCode Go Usage

A lightweight desktop tray app that monitors your OpenCode workspace usage — rolling, weekly, and monthly token quotas — without keeping a browser tab open.
Built with Electron, no official API required. v1.1.0

Features
  • Tray-based — Runs in the system tray, no browser needed
  • Live usage data — Rolling, weekly, monthly quota at a glance
  • Multi-account support — Add and switch between multiple OpenCode accounts
  • Custom glass account menu — iOS-style popover menu, no native <select>
  • API Key management — List, copy, and manage API Keys in an overlay panel
  • Manual cookie login — Sign in via your browser once, paste the auth cookie
  • Auto-hide to tray — Close button minimizes to tray
  • Configurable workspace — Switch between workspaces from the UI
  • Chinese i18n — Full Chinese localization for all UI text
  • Lightweight — ~60MB packaged, no background services
Install
Download
Download the latest installer from Releases.
Build from source
npm install
npm run build:win # Windows NSIS installer
Usage
First-time setup
  1. Launch the app. Click Login.
  2. Click Open OpenCode — this opens https://opencode.ai/workspace/<id>/go in your browser.
  3. Sign in with your account (Google OAuth).
  4. Press F12 → Application tab → Cookies → https://opencode.ai.
  5. Find the cookie named auth, copy its Value (starts with Fe26.2**...).
  6. Paste the value into the app's login panel and click Save Cookie.
Your workspace ID is auto-detected. If you need to switch workspaces, edit the Workspace ID field in the login panel and click Save Account.
Multiple accounts
  1. Click New in the footer to open a blank account editor.
  2. Enter a name, workspace ID, and paste the auth cookie.
  3. Click Save Cookie — a new account is created and becomes active.
  4. Use the account menu button (left of status pill) to switch between accounts.
API Keys
  1. Click Keys button (right of account menu) to open the API Key overlay.
  2. View masked keys in the list. Click Copy to copy a key to clipboard (main process, never exposed to renderer).
  3. Create/Delete are disabled until the POST seroval encoding is verified.
Daily use
  • Refresh — Click the Refresh button or right-click the tray icon → Refresh Usage
  • Hide to tray — Click × or close the window
  • Open config folder — Click Config to find config.json
Configuration
Configuration is stored at %APPDATA%\opencode-go\config.json (v1.1.0 multi-account format):
{
"activeAccountId": "acc_20260531_ab12cd34",
"accounts": [
{
"id": "acc_20260531_ab12cd34",
"name": "Main",
"workspaceId": "wrk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxx",
"auth": "Fe26.2**...",
"createdAt": "2026-05-31T00:00:00.000Z",
"updatedAt": "2026-05-31T00:00:00.000Z"
}
]
}
Legacy single-account config ({ "auth": "...", "workspace_id": "..." }) is auto-migrated on first launch.
You can also set environment variables:
set OPENCODE_AUTH=Fe26.2**...
set OPENCODE_WORKSPACE_ID=wrk_...
CLI Tools
The scripts/ directory contains standalone CLI tools (Node.js 18+):
# Fetch usage from command line
node scripts/fetch-usage-cli.js
# Pass auth as argument
node scripts/fetch-usage-cli.js "Fe26.2**..." [workspace-id]
# Verify runtime config and accounts
npm run check:accounts
# Verify runtime usage fetch
npm run check:usage:runtime
# List API Keys for active account
npm run check:api-keys
How It Works
OpenCode uses a custom seroval-based API protocol over standard HTTP. The app:
  1. Sends a GET /_server request with the function hash and seroval-encoded arguments
  2. Parses the seroval response to extract usage summaries and details
  3. Displays the data in the glass-morphism UI
No browser automation, no Puppeteer, no headless Chrome.

Security
  • Full auth cookies and API Keys are owned by the Electron main process
  • Renderer only receives masked previews (Fe26.2**...xxxx, sk-...xxxx)
  • API Key copy is a one-shot main-process clipboard action
  • No full secrets are logged or persisted in the UI
  • New account flow never allows deleting the active account

The scripts/ directory contains standalone CLI tools (Node.js 18+):
# Fetch usage from command line
node scripts/fetch-usage-cli.js
# Pass auth as argument
node scripts/fetch-usage-cli.js "Fe26.2**..." [workspace-id]
# Verify runtime config and accounts
npm run check:accounts
# Verify runtime usage fetch
npm run check:usage:runtime
# List API Keys for active account
npm run check:api-keys
How It Works
OpenCode uses a custom seroval-based API protocol over standard HTTP. The app:
  1. Sends a GET /_server request with the function hash and seroval-encoded arguments
  2. Parses the seroval response to extract usage summaries and details
  3. Displays the data in the glass-morphism UI
No browser automation, no Puppeteer, no headless Chrome.

Security
  • Full auth cookies and API Keys are owned by the Electron main process
  • Renderer only receives masked previews (Fe26.2**...xxxx, sk-...xxxx)
  • API Key copy is a one-shot main-process clipboard action
  • No full secrets are logged or persisted in the UI
  • New account flow never allows deleting the active account
