Willing to Pay / Sponsor This Feature

• I am willing to financially support / sponsor development of this feature if needed.
• This is a high-impact UX improvement that I would personally pay for.

Summary

OpenCode would benefit from a visual Git branch indicator built directly into the prompt input UI. This provides instant visibility of which branch users are working on without leaving the interface or running terminal commands.

Today, users have no visual indication of their current Git branch within the main interface, creating cognitive overhead when working across multiple branches.

🎯 Goals

• Display the current Git branch name in the prompt input dock tray
• Position it after the auto-accept permissions (shield) button
• Work on both web and desktop (using the existing server /vcs endpoint)
• Update in real-time when the branch changes
• Hide when the project is not a Git repository
• Support internationalization (17 languages)

Specifications

Behavior

• Hidden when project is not a Git repository
• Works on web AND desktop (uses server /vcs endpoint)
• Updates in real-time when branch changes (via vcs.branch.updated event)
• Tooltip shows "Current Git branch" on hover
• Long branch names truncate gracefully with ellipsis

📁 Technical Approach

Uses the existing server VCS endpoint (/vcs) which already tracks the current branch and emits real-time events on branch changes. No new backend work required.

// prompt-input.tsx
const branch = createMemo(() => sync.data.vcs?.branch)

<Show when={branch()}>
  <Tooltip placement="top" gutter={8} value={language.t("prompt.branch.tooltip")}>
    <div class="flex items-center gap-1 px-2 h-7 text-13-regular text-text-dimmed">
      <Icon name="branch" size="small" />
      <span class="truncate max-w-[120px]">{branch()}</span>
    </div>
  </Tooltip>
</Show>

🔗 Worktree-Aware by Design

This feature is designed to be compatible with git worktrees:

• Branch indicator shows the current worktree's branch
• Serves as foundation for future worktree UI enhancements

✅ Why This Is Not a Duplicate Request

Existing issues focus on git worktree infrastructure and workspace handling. This request is different because it addresses visual branch awareness in the UI - a simple UX improvement that complements those efforts.

🔗 Related Issues

• feature request: git worktree integration #564
• Multiple model usage with git worktrees #6679
• git worktrees and root-directory #2445
• Desktop app: opening multiple git worktrees replaces existing project #5638

🚀 Implementation Available

I have already implemented this feature and am ready to submit a PR:

• Branch: feature/git-current-branch-indicator
• Repository: https://github.com/slorenzot/opencode

💡 Key Benefits

• ✅ Essential for AI-assisted development: When working on projects with multiple branches, it's critical to always know which branch you're on when requesting code changes from the AI. Without this visibility, users risk accidentally committing AI-generated changes to the wrong branch (e.g., main instead of feature/new-login), leading to potential production issues or messy git histories.

• ✅ Prevents costly mistakes: A simple glance at the branch indicator before asking "refactor this component" or "fix this bug" ensures the AI's changes land in the correct context.

• ✅ Instant Git branch visibility without running commands

• ✅ Zero configuration required (built-in)

• ✅ Works on both web and desktop

• ✅ Uses existing infrastructure (no backend changes)

• ✅ Supports 17 languages

• ✅ Lays foundation for future worktree UI
