About this extension
★ TWITCH, BUT BETTER! ★
You know what your Twitch sidebar is missing? All those little bits of info you'd love to have WITHOUT clicking everywhere. ★ COWLOR'S SIDEBAR ★ adds them right where you're already looking. Simple, sleek, and oh-so-useful!
✨ WHAT IT ACTUALLY DOES:
➤ 📺 A LIVE PREVIEW ON HOVER
The flagship feature. Hover a streamer for one second and boom, a popup opens on the side with:
And it works everywhere in the sidebar: Followed Channels, Recommended Channels, and even "Viewers of X also watch". No more clicking just to find out what's happening on a stream!
➤ 🏷 BADGES THAT TELL YOU EVERYTHING
Inside the preview popup, colored labels sum up the stream's context at a glance:
➤ ⏱ "HOW LONG HAS HE BEEN STREAMING?"
No need to go to the stream anymore! The extension shows the live duration directly in the sidebar, right under the viewer count.
➤ 🎯 COLLABS FLAGGED ON THE AVATAR
A small purple dot appears in the bottom-right of the avatar of streamers hosting a co-stream, with the participant count. No hover needed, it's visible right in the sidebar. Clean, discreet, and it tells you instantly "ah, this one is collabing with 2 others".
➤ 💜 YOUR SUBSCRIPTIONS, IN GOLD
The channels you actually support shouldn't look like all the others. Now they don't:
➤ ✨ NEVER MISS A STREAM START AGAIN!
Instantly spot streams that just went live! A subtle purple bar on the left side flags streams that started in the last few minutes.
➤ ⚡ QUICKER THAN TWITCH ITSELF
Twitch refreshes its own sidebar rarely: a followed channel that just went live can take 2 to 4 minutes to show up, and one that just stopped lingers there for 5 to 10. The extension refreshes all of it itself, every 30 seconds — viewers, category, language, uptime, appearing and disappearing. You see it before Twitch does.
➤ 🚂 AND GOODBYE VISUAL CLUTTER
We've cut out everything that makes the sidebar a mess:
Result: your sidebar only shows what matters. With nothing to configure.
➤ 📂 NO MORE "SHOW MORE" TO CLICK
The full list of your followed channels is automatically unfolded on every page load. You see everything, right away.
➤ 🔍 CATEGORY FILTER
A filter bar appears above your list. Pick a category (Just Chatting, League of Legends, IRL…) and only streamers playing that category stay visible. The category list is computed on the fly: only the ones your followed streamers are actually live in.
➤ 🌐 LANGUAGE FILTER
Same principle, but for the streams' language. A dropdown with flags lets you show only the streamers broadcasting in the language you pick. Here too, only the languages actually present among your live followed channels are offered: no endless list, just what's relevant to you.
➤ 🏆 TOP CHANNELS: ALL OF TWITCH IN YOUR SIDEBAR
One tab at the top of the sidebar, one click, and it flips: instead of your followed channels, the 30 most-watched channels on Twitch, live.
One click to get there, one click back. Your followed channels don't move a pixel.
➤ 🔄 SIX WAYS TO SORT YOUR LIST
Six buttons at the top of the sidebar to rearrange everything on the fly:
➤ 📊 YOUR TOP STREAMERS, LOCALLY
The extension remembers which channels you visit, when, and how often. This data powers the "Personal Popularity" sort and stays stored ONLY in your browser. Nothing leaves your machine.
You can check your top in the DevTools console (F12):
- tse.scores() → your top streamers
- tse.scores.raw() → raw data
- tse.subs() → the subscriptions the extension has spotted
- tse.subs.refresh() → re-read them right now
- tse.reset() → wipe everything
➤ 🎮 HOW DO WE DO IT?
That's it. Really. No complicated configuration, no hidden menus, no account to create. It works, period.
➤ 💜 WHY YOU'LL LOVE IT
➤ 🌍 IN YOUR LANGUAGE
The extension automatically detects your Twitch language and adapts every label, badge and tooltip:
There is strictly nothing to configure.
➤ 🔒 PRIVACY PEACE OF MIND
➤ 🤔 WHO IS IT FOR?
➤ 🎉 INSTALL AND ENJOY!
The extension evolves thanks to your feedback, so don't hesitate to tell us what you think!
★ Install COWLOR'S SIDEBAR now and rediscover your favorite Twitch! ★
P.S.: This extension is not affiliated with Twitch, but we love them anyway 💜

✨ WHAT IT ACTUALLY DOES:
➤ 📺 A LIVE PREVIEW ON HOVER
The flagship feature. Hover a streamer for one second and boom, a popup opens on the side with:
- The LIVE stream video (actual live feed, not a frozen thumbnail)
- The full stream title, readable before you even click
- Badges that tell you everything about the context (see right below)
- And it plays on labelled channels too: Twitch's "Start Watching" screen used to leave the preview stuck on a still image — now it is lifted, and the labels move into a badge (see below)
And it works everywhere in the sidebar: Followed Channels, Recommended Channels, and even "Viewers of X also watch". No more clicking just to find out what's happening on a stream!
➤ 🏷 BADGES THAT TELL YOU EVERYTHING
Inside the preview popup, colored labels sum up the stream's context at a glance:
- 🤝 ★ CO-STREAM ★ Tells you precisely whether the channel is the host or a guest, and with whom. No more "wait, who is this stream I didn't follow?".
- 👥 ★ LIVE WITH ★ For squads and multistreams, shows the main co-streamer and total count of others ("Live with So-and-So and 3 others").
- 💜 ★ SUBSCRIBED ★ How long you've been supporting the channel ("Subscribed 9 months") — or that you used to ("Formerly subscribed 22 months").
- 💰 ★ SPONSORED BY ★ For sponsored streams, displays the brand with its color logo. You'll know who's behind it.
- 🚂 ★ HYPE TRAIN ★ A Hype Train is running on the channel? You're notified without having to click.
- 💎 ★ DISCOUNTED SUB ★ When Twitch is offering a discounted subscription on the stream, it's flagged right there.
- 🆕 ★ JUST SWITCHED TO ★ The streamer changed category mid-stream? A green badge says so for ten minutes: "Just switched to Elden Ring". Twitch announces it nowhere — the extension sees it because it keeps watching.
- ⚠ ★ CONTENT LABELS ★ The official Twitch labels (mature-rated game, graphic violence, gambling…) are shown as their own badge, first in the row — so you know before you look, without the interstitial that used to block the video.
➤ ⏱ "HOW LONG HAS HE BEEN STREAMING?"
No need to go to the stream anymore! The extension shows the live duration directly in the sidebar, right under the viewer count.
- 4h19, 14h29… you see it at a glance.
- It updates automatically, in real time.
- And when a stream ends, the counter switches to a subtle italic "Ended" before Twitch even removes the streamer from the list.
➤ 🎯 COLLABS FLAGGED ON THE AVATAR
A small purple dot appears in the bottom-right of the avatar of streamers hosting a co-stream, with the participant count. No hover needed, it's visible right in the sidebar. Clean, discreet, and it tells you instantly "ah, this one is collabing with 2 others".
➤ 💜 YOUR SUBSCRIPTIONS, IN GOLD
The channels you actually support shouldn't look like all the others. Now they don't:
- ★ THE WHOLE CARD LIGHTS UP ★ Golden name, golden category, a gold ring around the avatar, and a slow shimmer in the background of the card. Discreet, but you can't miss it.
- ★ A SORT OF THEIR OWN ★ "My subscriptions first" pushes them all to the top of the list, with your total on a little badge.
- ★ EVERY KIND COUNTS ★ Paid, gifted, mobile: all three are recognized, and all three wear the same gold.
- ★ HOW LONG YOU'VE BEEN THERE ★ Hover a channel and the preview tells you: "Subscribed 9 months". And for one you supported in the past: "Formerly subscribed 22 months".
- ★ IT FIGURES IT OUT ALONE ★ Nothing to configure, no login, no password, no token. How exactly? It's spelled out in the PRIVACY section further down, in plain words.
➤ ✨ NEVER MISS A STREAM START AGAIN!
Instantly spot streams that just went live! A subtle purple bar on the left side flags streams that started in the last few minutes.
- A subtle, elegant visual effect to welcome the streamer.
- Perfect for being among the first and never missing the intro!
- The animation fades on its own after a few minutes.
➤ ⚡ QUICKER THAN TWITCH ITSELF
Twitch refreshes its own sidebar rarely: a followed channel that just went live can take 2 to 4 minutes to show up, and one that just stopped lingers there for 5 to 10. The extension refreshes all of it itself, every 30 seconds — viewers, category, language, uptime, appearing and disappearing. You see it before Twitch does.
➤ 🚂 AND GOODBYE VISUAL CLUTTER
We've cut out everything that makes the sidebar a mess:
- Hype Trains that take up half the space (info still available as a badge in the preview, don't worry, nothing is lost)
- Intrusive sub-discount banners
- Streamers who just went offline and are still lingering
- Entire sections that end up empty
- Redundant visual indicators (those ambiguous little colored circles, useless "DROPS REBROADCAST" lines…)
- Sponsorship banners that disfigure streamer entries: we clean it all up, and the "sponsored by X" info is restored inside the preview, way cleaner.
Result: your sidebar only shows what matters. With nothing to configure.
➤ 📂 NO MORE "SHOW MORE" TO CLICK
The full list of your followed channels is automatically unfolded on every page load. You see everything, right away.
➤ 🔍 CATEGORY FILTER
A filter bar appears above your list. Pick a category (Just Chatting, League of Legends, IRL…) and only streamers playing that category stay visible. The category list is computed on the fly: only the ones your followed streamers are actually live in.
➤ 🌐 LANGUAGE FILTER

➤ 🏆 TOP CHANNELS: ALL OF TWITCH IN YOUR SIDEBAR
One tab at the top of the sidebar, one click, and it flips: instead of your followed channels, the 30 most-watched channels on Twitch, live.
- 🌍 ★ THE GLOBAL RANKING ★ Recomputed continuously, not a frozen list.
- 🎮 ★ BY CATEGORY ★ Pick Just Chatting, GTA V, League of Legends… and you get the 30 biggest streams IN that category.
- 🇬🇧 ★ BY LANGUAGE ★ Pick a language and you get a genuine top 30 for it — not a rough filter slapped on an English list.
- 👀 ★ EVERYTHING ELSE FOLLOWS ★ Hover preview, stream uptime, badges, co-streams: they're cards like any other.
- ✅ ★ HONEST ★ When the ranking can't be guaranteed complete, the extension tells you. No made-up numbers.
One click to get there, one click back. Your followed channels don't move a pixel.
➤ 🔄 SIX WAYS TO SORT YOUR LIST
Six buttons at the top of the sidebar to rearrange everything on the fly:
- 👁 ★ BY VIEWERS ★ Twitch's default sort, clean.
- 💎 ★ MY SUBSCRIPTIONS FIRST ★ The channels you support, grouped at the top, with your total on a badge.
- ⭐ ★ BY PERSONAL POPULARITY ★ Based on your own local visit history. Your favorite streamers rise to the top.

- 🔗 ★ CO-STREAMS FIRST ★ All co-streams grouped at the top of the list. Never miss a collab again!
➤ 📊 YOUR TOP STREAMERS, LOCALLY
The extension remembers which channels you visit, when, and how often. This data powers the "Personal Popularity" sort and stays stored ONLY in your browser. Nothing leaves your machine.
You can check your top in the DevTools console (F12):
- tse.scores() → your top streamers
- tse.scores.raw() → raw data
- tse.subs() → the subscriptions the extension has spotted
- tse.subs.refresh() → re-read them right now
- tse.reset() → wipe everything
➤ 🎮 HOW DO WE DO IT?
- Click "Add to Chrome" (it's free!)
- Reload Twitch and… tadaaaa!
That's it. Really. No complicated configuration, no hidden menus, no account to create. It works, period.

➤ 🌍 IN YOUR LANGUAGE

- 🇪🇸 Español
- 🇧🇷🇵🇹 Português (Brazil and Portugal)
- 🇮🇹 Italiano
- 🇵🇱 Polski
- 🇷🇺 Русский
- 🇯🇵 日本語
- 🇨🇳 简体中文
- 🌐 …and English by default for every other language
There is strictly nothing to configure.
➤ 🔒 PRIVACY PEACE OF MIND
- ★ No third-party server ★ The extension only talks to Twitch's own public API — the very one the page already uses to render itself. Nothing else, nowhere.
- ★ Anonymous calls ★ No session token, no cookie is ever sent: those requests cannot be tied back to your account.
- ★ One exception, said out loud ★ To know which channels you subscribe to, the extension opens YOUR own twitch.tv/subscriptions page in an invisible frame, at most once every six hours, and never when you're signed out. Your browser authenticates that page with its own cookies, exactly as if you had clicked the link: the extension never reads your token and never passes it on. What it keeps — channel names and a tenure in months — stays in your browser.
- ★ No tracker, no pixel, no telemetry ★
- ★ No shady permissions ★ The extension ONLY runs on twitch.tv.
- ★ Ad blocking stays in its lane ★ It applies to the hover preview thumbnail and to nothing else. The stream you're actually watching is untouched.
- ★ Your history stays with you ★ Visits, subscriptions, months: stored in your browser's localStorage, period. Clear twitch.tv site data and it's all gone.
- ★ Full source code readable ★ Right in the extension folder. No black box.
➤ 🤔 WHO IS IT FOR?
- ★ YOU FOLLOW 50 STREAMERS? ★ See at a glance who's been live for a while and who just started.
- ★ YOU SUB TO A DOZEN CHANNELS? ★ They're in gold, grouped at the top, with the number of months you've been there.
- ★ YOU ALWAYS MISS CO-STREAMS? ★ A dedicated sort brings them to the top, and a badge tells you who's playing with whom.
- ★ YOU HATE VISUAL CLUTTER? ★ No more Hype Trains squatting the sidebar, no more ad banners, no more empty sections.
- ★ YOU JUST LOVE TWITCH? ★ This extension is made for you!
➤ 🎉 INSTALL AND ENJOY!
The extension evolves thanks to your feedback, so don't hesitate to tell us what you think!
★ Install COWLOR'S SIDEBAR now and rediscover your favorite Twitch! ★
P.S.: This extension is not affiliated with Twitch, but we love them anyway 💜
