How it works

Three steps to a better internet.

STEP 01

Install once, comment and react forever

Grab the extension from your browser's store. Takes about 30 seconds and you'll never have to think about setup again.

STEP 02

Open any supported page

Hit play on YouTube, load up Netflix, or visit any supported site. The SideReacts panel appears beside the page automatically, or stays hidden until you need it.

STEP 03

Say the thing everyone's thinking

Drop a reaction, attach a GIF, upvote the takes you love, and jump into conversations tied to the exact moment or page you're on.

Features

Everything a comment section wishes it could do.

Timestamped reactions

Comment and react to the exact moment.

Pin your reaction to a specific second in the video. One tap jumps everyone straight to that scene. Because “you know, that part” doesn't cut it.

Upvotes & downvotes

The best takes rise. The bad ones don't.

Vote up the reactions that nail it. The best stuff floats to the top, and fresh takes always get a fair shot too.

Threaded replies

Actual conversations, not a wall of noise.

Replies stay organized so you can follow the threads you care about without drowning in every side argument.

Images & GIFs

Words aren't always enough.

Search and attach GIFs or drop an image right inside the reaction panel. Express the inexpressible. Regular comment sections can't do this. SideReacts can.

Anonymous identity

Hot takes. Zero accountability drama.

Your real name and email are never shown to anyone, ever. Comment and react freely, reply honestly, and be your unfiltered self.

Reply notifications

Know when you've been replied to.

Get notified when someone upvotes or replies to your reaction. No inbox clutter, no noise. Just the stuff that actually matters.

Community

Good vibes, by default.

The internet can be a lot. SideReacts keeps things clean so you never have to think about it.

Bots don't make it past the door.

Spam, bot accounts, and flood posts are caught automatically before they ever reach your feed.

Safe images, always.

Every image is checked before anyone sees it. Harmful or inappropriate content never makes it into a thread.

No sketchy links. Ever.

External links are blocked in comments entirely. No phishing, no spam, no one trying to sell you something. Just reactions.

The community has your back.

See something off? Flag it. Every report gets acted on so threads stay worth reading.

Platforms

Works where you already spend time.

Every page gets its own thread. Your anonymous identity carries across all of them.

YouTube

YouTube already has comments. SideReacts makes them actually fun. Drop a GIF, pin a reaction to a timestamp, and watch the best takes rise to the top. Works on regular videos, Shorts, and embeds.

Netflix

Finally, someone to comment and react with. Every title gets its own thread so your reactions stay tied to exactly what's on screen. No spoilers leaking in from episode 8 when you're on episode 3.

Privacy

Your reactions are public.
You aren't.

We use your email for exactly one thing: keeping spam out. Your name, your identity, your business. None of it is ever shared.

We're protecting you, not watching you.

Every post is screened before it goes live. Spam, harmful images, and sketchy links are blocked automatically.

Your email stays between us.

It's never shown publicly, never shared, never sold. Full stop.

A random identity that's actually yours.

You post as your SideReacts persona: a random username and avatar. Your real name never enters the picture.

No tracking. No ad profiles. No selling.

We only store what it takes to run the service. That's it.

FAQ

Questions you might have.

How does SideReacts prevent spam?
Every post is checked automatically before anyone sees it. On top of that, Google sign-in keeps most bots out from the start, and anyone can flag something that slips through. The feed mostly looks after itself.
Which browsers does SideReacts support?
Chrome, Firefox, Edge, Brave, and pretty much any Chromium-based browser. Install free from your browser's extension store.
How much does it cost?
Nothing. SideReacts is completely free. No subscriptions, no premium tiers, no catch.
Do I have to make an account?
You can browse and read reactions without signing in. To post, vote, or reply, you sign in with Google just to keep bots out. From there you get a random username and avatar that works everywhere SideReacts runs.
Can people find out who I am?
Nope. Everyone sees your random username and emoji avatar. Your real name and email are never part of the picture.
What can I actually post?
Text, images, GIFs, and timestamps on supported video platforms. External links aren't allowed, which keeps things clean and on-topic.
Will it interfere with what I'm watching or reading?
Not at all. SideReacts sits beside the content. It never touches or interferes with the page you're on.

Everything's better with reactions.

Add SideReacts and start commenting and reacting in under a minute. Free, forever.
