Reactify (branded HypeLayer on its store card) overlays emoji reactions and mini-threads on webpages. Web Reactions is the alternative for people who read the listing's web-history disclosure and closed source and wanted neither.
Two lines on Reactify's own Chrome Web Store card do most of the work. The privacy section discloses handling web history, and no public source repository is linked, so there's no independent way to check what the overlay does inside your pages.
There's also a quieter product reason: HypeLayer reacts to pages. On a feed, a marketplace, or a repo list, the interesting unit is the thing on the page: the post, the product, the repo. A page-level overlay can't tell them apart.
Web Reactions doesn't collect browsing history and its privacy policy says exactly what the server sees instead: an irreversible account hash, the reaction, and the public target it applies to. Because the extension is open source, that claim is checkable rather than take-our-word-for-it.
Site adapters attach the reaction control to the actual object: a Facebook post, a GitHub repo, a YouTube video, an Amazon product. Counts follow the target, so the same product page seen through different URLs still shows one honest number.
Reactify's listing doesn't describe how users map to reactions. Web Reactions makes it the core rule: one verified email, hashed irreversibly, holds one current reaction per target — so a count of fifty means fifty people.
The extension is GPL-3 on GitHub, and every reaction lands in a public log an open-source verifier can recompute.
Install the extension, react on a supported site, and confirm the one-time email code. Reading counts requires no account at all.
Choose Web Reactions if you want page reactions without a web-history disclosure, with open code and counts that mean something.
Stay with Reactify / HypeLayer if its mini-threads and shareable highlighted links are the features you actually use — Web Reactions deliberately doesn't do threads.
