Make X Great Again: A Free, Open-Source Spam Blocker Extension for X

The GitHub README for Make X Great Again promises four things: a spam shield, a "KOL signal score," a profile digest, and social graph hints. As of today's v0.5.0 alpha release, exactly one of those four is actually built. The other three are documented roadmap items with no shipped code behind them yet. That's worth knowing before installing this x spam blocker extension expecting the full pitch from the description, because what is live is still genuinely useful on its own, just narrower than the four-item list suggests.

What's live in v0.5.0, and what isn't

Make X Great Again is a free, open-source browser extension, licensed AGPL-3.0, that syncs a community-maintained public blocklist of spam and low-quality accounts, then applies local matching against every profile and post you scroll past on X. That's Pillar 01 of the project's five-pillar roadmap, and it's the only pillar that has shipped. Pillars 02 through 05, the KOL (key opinion leader) credibility score, an account profile digest, and social graph signal visibility, are documented as planned, not built. The maintainer is explicit about this split in the project's own repo, so this isn't a case of a marketing blurb outrunning the tool. It's a young project that's honest about being early, with a public roadmap for what comes next rather than a vague "coming soon."

The project has real momentum for something this young: 625 GitHub stars, more than 1,300 commits on the main branch, and a commit pushed the same day this piece was written. That's an actively maintained repo, not an abandoned weekend demo with a good README.

How the spam shield actually works

Once installed, the extension checks each account you see against the synced blocklist and flags matches with a visual badge. You get three ways to handle a flagged account: local hiding (the default, which never calls X's own API at all), muting through your own X login, or blocking through your own X login. Local hiding is the safer default precisely because it doesn't touch X's API or your account's action history, it just changes what your own browser renders on your own screen. Every hide comes with a five-second undo, and if the extension ever flags an account you disagree with, there's an appeal process through GitHub issues rather than a black-box override you can't contest.

The muting and blocking modes deserve a second thought before switching them on. They go through your own logged-in session and X's normal mute and block actions, and the extension rate-limits its own queue specifically to avoid tripping X's account-restriction systems. That's a sensible safeguard built in by the maintainers, but it also means those two modes carry a small amount of the same automation risk that any tool acting through your account on your behalf does. Worth knowing going in, rather than assuming it away because the extension is open source.

Installing it

Make X Great Again supports the browsers most people are actually on: Chrome, Edge, Brave, and Arc through the standard Chromium extension format, Firefox 109 and up, and Safari on macOS 15 and iOS/iPadOS 18 through TestFlight. Installation is a normal extension-store install with no account or signup required, which matters for a tool explicitly framed by its own maintainer as public-good software rather than a product with a growth funnel behind it.

Because it's alpha software, expect some rough edges and occasional behavior changes between releases. The project's own v0.5.0 version number and its stated "governance rules" both signal that defaults may still shift before a 1.0 release, so it's worth rereading the release notes after an update rather than assuming last week's behavior still holds.

Who this fits, and who should wait

If you spend real time scrolling X and you're tired of the same recycled spam accounts and engagement-farming replies showing up in your notifications and replies, the live spam-shield feature alone is worth installing today. It's free, it doesn't require handing a third-party service your login credentials, and the default local-hiding mode is about as low-risk as a browser extension gets: nothing leaves your browser, and nothing about your account's history on X changes.

If what actually drew you in was the idea of a credibility score on the accounts you follow, or a digest that summarizes an unfamiliar profile before you decide to engage, hold off. Those features don't exist yet, and installing the extension today for that reason will leave you waiting on a roadmap rather than using a working tool. Check the repo's own release notes before assuming a later update has shipped them, since an early-stage open-source project's pace between releases can vary a lot, and a GitHub description written for where the project is headed is not the same thing as where it actually is right now.
