Both extensions add a reaction layer where the platform doesn't have one. The difference is in the details: who can see the reactions, who maintains the code, and what the extension discloses about your data.
Per its Chrome Web Store card, Emoji Reactions in Twitter is a Chrome-only extension whose reactions are "visible only to other users of the same extension". The store card also discloses handling of authentication information, and dates its last release March 2022.
Emojery is GPL-3, runs on Chrome / Firefox / Edge, supports a growing list of social, dev, and shopping sites, never asks for your Twitter or any other platform's credentials, and uses a provider sign-in to make sure each reaction count reflects an account a provider vouched for rather than an anonymous install.
| Emojery | Emoji Reactions in Twitter | |
|---|---|---|
| Sites covered | 14 and growing — Facebook, Instagram, Reddit, GitHub, GitLab, YouTube, X, Threads, Amazon, Rotten Tomatoes, TMDB, IMDb, Metacritic, and OpenCritic | Twitter / X only |
| Reactions visible to | All Emojery users — aggregated public count | Only other users of the same extension |
| Source code | Public on GitHub, GPL-3 | Closed source. No public repository linked from the store card. |
| Privacy disclosure | One-way identifier derived from an opaque provider id, no name or email ever requested, a daily-rotating network marker for rate-limiting, and reaction context unless you switch it off (policy) | Chrome Web Store card discloses handling of authentication information. |
| Identity model | One provider account = one account | Not publicly documented |
| Last public release | Continuously released from GitHub | 2022-03-05 per the Chrome Web Store card |
| Browsers | Chrome, Firefox, Edge | Chrome only |
Emoji Reactions in Twitter operates only on Twitter. If you also want reactions on a Facebook post you saw earlier, a GitHub repo, or an Amazon product, this extension simply has nothing for you. Emojery covers all 14 supported sites, with the same picker, same counts, and same history view across every one of them. Adding the next site (Stack Overflow, Hacker News, an internal company portal) means shipping a small reviewed adapter instead of a fork.
Emoji Reactions in Twitter is closed source — the Chrome Web Store card doesn't link a public repository. That's not a crime, but it does mean you trust the binary you install without an independent way to verify what it does.
Emojery is GPL-3. The extension code is on GitHub. Security researchers can audit it; users can compile their own build; nobody has to take our word for anything.
Emoji Reactions in Twitter's reactions are only visible to other users of the same extension. That's a design choice with real consequences: a viral tweet's "real" reaction count is hidden behind extension adoption, and the same person on 3 browsers will count 3 times.
Emojery's counts are aggregated globally and gated on a provider sign-in. The count under a Facebook post in Emojery means "this many provider-backed Emojery accounts reacted with this emoji", not "this many people who happened to install the same browser plugin you did".
Twitter/X has been through several major UI overhauls since March 2022 — including a brand change. Any DOM-touching extension that hasn't been updated since then is one Twitter release away from breaking. Emojery keeps site-specific adapters small and bundled with the extension, so X fixes can ship as focused extension updates instead of broad rewrites.
One thing the older extension does, Emojery deliberately doesn't: it keeps reactions inside its own circle of users, visible to nobody else. If a semi-private reaction on a tweet is what you were after, that is a real design difference rather than a shortcoming, and no aggregate count will give it to you.
Everything else points the other way. Emojery is open source, maintained against an X that has been redesigned repeatedly since March 2022, runs on 14 sites instead of one, and ties every count to a verified account. On X it adds the full palette next to every post; see emoji reactions for X (Twitter).
