Best Reddit Keyword Filter Extensions 2026

The best Reddit keyword filter in 2026 is Ultimate Reddit Filter — the only actively-maintained free extension that filters by keyword, flair, AND subreddit, and the only one that reaches comments as well as posts. For users who want zero configuration and only need to block political content, the simpler Reddit Keyword Filter ships with politics presets built-in.

TL;DR

• Most powerful: Ultimate Reddit Filter — keyword + flair + subreddit + comments, free, actively developed.
• Fastest setup: Reddit Keyword Filter — politics preset built-in, one toggle.
• Legacy / power-user toolkit: Reddit Enhancement Suite — feature-rich but in maintenance mode since 2022.
• Nuclear option: News Feed Eradicator — removes the Reddit feed entirely.
• Reddit’s own filters cover subreddit mutes only — none of these are built in.

Why you need an extension at all

Reddit’s native filtering in May 2026 covers exactly two things: muting an entire subreddit, and toggling NSFW content. There is no keyword blacklist, no flair filter, no domain block, no comment filter. Everything else requires a browser extension.

Most people land here for one of three reasons:

1. Political headlines are dominating r/all and r/popular.
2. One specific topic — AITA, crypto, sports, a celebrity name — is unavoidable.
3. Promoted posts and ads are leaking past their ad-blocker.

All three are solved problems. The right tool depends on how much granularity you need.

How we picked

• Verified this month. Every install link tested in May 2026.
• Active development. Tools in maintenance mode are flagged but still listed for completeness.
• Privacy. Anything that phones home is excluded.
• Free or trivially priced. Reddit filtering is a commodity — there is no reason to pay.

The 2026 ranking

1. Ultimate Reddit Filter — Best overall

Pricing: Free · Platforms: Chrome, Firefox · Rating: 4.5 / 5 · Profile

The only standalone Reddit filter in 2026 that does all three filtering axes — post title keyword, flair label, and subreddit name — and the only free tool that extends filtering to comments. Actively maintained: last update April 28, 2026. Import/export, relabel-instead-of-hide mode, zero telemetry.

Pick it if: You want full control. This is the default recommendation for anyone past their first day on Reddit. Skip it if: You literally just want a one-click politics toggle.

2. Reddit Keyword Filter — Fastest to set up

Pricing: Free · Platforms: Chrome only · Rating: 3.8 / 5 · Profile

The simplest possible Reddit filter — type words, save, reload. Ships with politics presets pre-loaded, so the install-to-results time is well under 60 seconds. Also hides Reddit ads as a side-effect.

Pick it if: You want politics gone in 30 seconds and don’t care about flair or subreddit filtering. Skip it if: You want Firefox support, comment filtering, or flair matching.

3. Reddit Enhancement Suite (RES) — Legacy power-user toolkit

Pricing: Free · Platforms: Chrome, Firefox, Edge, Safari · Rating: 3.5 / 5 · Profile

RES dominated Reddit power-user culture for over a decade. It still works in May 2026, but the project has been in maintenance mode since 2022 with only two active volunteers. Filtering is one feature of dozens (user tags, account switching, custom CSS, regex filters). For filtering alone it’s heavier than you need.

Pick it if: You’re already a RES user or you want its non-filtering features. Skip it if: Filtering is all you need — install Ultimate Reddit Filter instead.

4. News Feed Eradicator — The nuclear option

Pricing: Free · Platforms: Chrome, Firefox · Rating: 4.3 / 5 · Profile

Not a keyword filter — a feed remover. Replaces the entire Reddit homepage with an inspirational quote. You can still browse specific subreddits, post, and message. The algorithmic firehose is gone.

Pick it if: You’ve tried keyword filtering and the feed still pulls you in. Skip it if: You want to keep browsing r/all selectively.

What we won’t recommend

• Any “Reddit filter” extension last updated before 2024. Reddit ships UI changes constantly; stale extensions break silently.
• Extensions requiring a login to a third-party service. Reddit filtering doesn’t need an account anywhere.
• Browser extensions that request permissions beyond reddit.com. Filtering Reddit doesn’t require access to “all websites you visit.”

When a keyword filter isn’t enough

If topics still get through or you’re opening Reddit compulsively rather than just seeing specific content, the next layer is a site blocker:

• Freedom [partner link] — blocks Reddit across every device simultaneously with a Locked Mode you can’t skip
• Cold Turkey [partner link] — desktop-only, one-time $39, the strictest available lockout
• News Feed Eradicator — removes the Reddit homepage entirely while keeping subreddit browsing, search, and messaging

What to do next

1. Install Ultimate Reddit Filter (60 seconds).
2. Copy one of our starter blocklists.
3. Reload Reddit. If the feed is still pulling you in after filtering, add Freedom [partner link] for scheduled lockouts.
