Displays the stream language as [EN]/[JA]/etc. Configurable, with two UI modes: a badge on the stream preview or a suffix next to the streamer’s username
Userscript for browsers that displays stream’s language code like [EN] / [JA] / [ES] right in the Twitch UI. Works on channel preview cards in directories and on the channel page header itself. Two visual modes are available: a top‑right badge on the card or a right‑aligned suffix next to the streamer's username.
Open the script in your userscript manager and change the value of:
const VISUAL_MODE = 'suffix';
suffix - adds label next to the streamer's username.
badge - adds small pill in the top-right corner of the preview card.
The script passively listens to Twitch’s SPA updates and XHR GQL responses, extracts language info from fields like broadcasterLanguage, language, and content tags, and maps localized tag names to ISO‑like codes when needed. It then annotates relevant DOM nodes as they appear.
In rare cases, you may see a [??] suffix — this happens when the stream has no language set in GQL and no recognizable custom tags to infer it from. This is a known issue and I’m exploring possible ways to improve detection; it may be resolved in future updates.
