[FEATURE]: Configurable web UI title to tell multiple instances apart

Feature hasn't been suggested before.

I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

I run several opencode web instances at once, one per project. Every browser tab is titled "OpenCode", so I can't tell them apart and have to click through tabs to find the one I want.

packages/app/index.html hardcodes <title>OpenCode</title> and nothing overrides it at runtime, so there is currently no way to distinguish instances.

I'd like to set the title per instance with an env var:

OPENCODE_WEB_UI_TITLE="work: frontend" opencode web

I have a working change that rewrites the <title> in the served HTML, for both the embedded UI and the proxied dev UI, and leaves the title alone when the variable is unset. Happy to open a PR if you're open to this approach.

This issue might be a duplicate of an existing issue. Please check:

[FEATURE]: make window title show the currently selected session + project #31423: Same problem — static "OpenCode" browser title makes it hard to tell multiple tabs/instances apart (closed)
[FEATURE]: (Web UX) Update browser tab title While OpenCode Is Processing #22658: Related — request to update the browser tab title dynamically during processing (closed)

If your request is distinct (per-instance configurable title via env var rather than dynamic session/project name), that difference is worth clarifying in your issue so maintainers can decide whether to reopen #31423 or track this separately.

@neumark

Thanks for the request, @neumark! To restate it: you'd like to set the browser tab title for each opencode web instance (for example with OPENCODE_WEB_UI_TITLE="work: frontend"), so you can tell several instances apart at a glance.

One thing to check before you open a PR: the web app sets the tab title itself once it loads. It uses @solidjs/meta (<Title>OpenCode</Title> in packages/app/src/app.tsx, and <session title> · OpenCode in packages/app/src/session/route.tsx on session pages). So rewriting <title> in the served index.html would probably be replaced as soon as the app loads. A version that passes the configured label into those <Title> calls, for example as a prefix like work: frontend · OpenCode, would likely work better.

feat: configurable web UI title via OPENCODE_WEB_UI_TITLE #47907: your earlier PR for this. It was closed by the automated stale-PR cleanup, not after a review.
[FEATURE]: make window title show the currently selected session + project #31423: an earlier request for a tab title that follows the current session and project. It was closed after going stale.
[FEATURE]: Show which server a session tab belongs to #51344: an open request to show which server each session tab belongs to.

Maintainers will consider this.

Thanks for the suggestion! This was added in #59131 and shipped in v2.2.0, so I'm closing this issue.
