uBlock Origin vs AdGuard AdBlocker

Side-by-Side Comparison

Which Should You Choose?

uBlock Origin is the better-proven option given its large review base; AdGuard AdBlocker is worth considering if you specifically want a privacy-focused developer with dedicated filter maintenance.

Both extensions share a 4.7-star rating, but uBlock Origin's score is backed by 25,364 reviews versus a much smaller review base for AdGuard AdBlocker. uBlock Origin is open-source and community-maintained, while AdGuard AdBlocker is built by a dedicated commercial team that also ships broader AdGuard privacy tools. If review volume and track record matter most to you, uBlock Origin is the safer bet; if you want a blocker from a company solely focused on ad and privacy protection, AdGuard is a solid alternative.
