An index, not a platform
Reactors exists to answer one question: who has reacted to this, and where can I watch it? Nothing more complicated than that.
What it is
Reaction videos are one of YouTube's biggest genres, and one of the hardest to actually navigate — a good reaction to a show you love might be scattered across a dozen different channels, in a dozen different upload orders, with no single place to see who's covered what. Reactors is that place: a catalog of 33,314 reaction videos across 3,919 movies and shows, from 82reactors, organized episode by episode so you can find exactly the reaction you're looking for — or discover a reactor you'd never have found otherwise.
What it isn't
Reactors doesn't host, download, or re-upload any video. Every reaction on this site links straight back to the original creator's own YouTube upload — that's a deliberate choice, not just a legal one. The reactors are the ones doing the actual work of watching, reacting, and building an audience; this site's only job is to make what they've made easier to find. There are no ads here, and there won't be — the closest thing to a business model is an optional, entirely voluntary way to support the project directly (more on that below).
How it's organized
Every show on the site has a real episode catalog behind it — not just a pile of videos, but actual season and episode data, so a reactor's coverage can be shown as a genuine progress map rather than a guess. Four franchises (Game of Thrones, South Park, The Walking Dead, and Lord of the Rings) even get their own visual theme, because some shows earn it.
Who it's for
Two kinds of people, really: someone who just finished an episode and wants to see three different reactions to the ending, and someone who wants to follow a specific reactor's entire journey through a show from episode one. The site is built for both — browse by title, browse by reactor, or just follow along with whatever's trending.
Who's building it
Reactors is a fan-made project, built and maintained by one person, not a company. That's also why it's free and ad-free — there's no investor or ad network to answer to, only the people actually using it. If the site is useful to you, the best way to help it grow is simple: tell a reactor you follow that they're on it, or subscribe to updates so new coverage doesn't pass you by.
Questions or corrections
Found a reactor who should be added, a reaction that's missing, or something that's just wrong? The catalog is maintained by hand and mistakes happen — get in touch or use the suggestions feature from your account.
