AntiAdBlock Core vs BlockAdblock
AntiAdBlock Core vs BlockAdblock
A multi-signal managed detector vs a free, static bait script the filter lists already know.
BlockAdblock is the best-known free anti-adblock script: a small open-source snippet you self-host that drops a bait element on the page and checks whether an ad blocker hides it. For years it was the default DIY option for publishers who wanted detection without paying for it.
That is also its weakness. A single-signal bait script is easy to fingerprint, so BlockAdblock has long been targeted directly by EasyList and the major anti-adblock filter lists. Once a rule ships, the script stops detecting and gets no update. AntiAdBlock Core is the maintained, multi-vector alternative built for the way blockers work now.
| Feature | BlockAdblock | AntiAdBlock Core |
|---|---|---|
| Transparent public pricing | Free, open source (you self-host) | Public: every tier listed ($0–$29.99/mo) |
| Free plan | Yes, but static and effectively unmaintained | Yes, 10k requests/mo, full detection engine |
| Detection vectors | One bait-element check | multiple independent signals, voted in real time |
| uBlock Origin Lite (Chrome MV3) | No, and its pattern is in filter lists | Detected: Basic, Optimal & Complete |
| Time to first detection | Manual: host, configure and wire it yourself | ~60 seconds, one async script tag |
| Domain-locked + signed script | No, the snippet runs anywhere it is pasted | Yes, origin-pinned, tamper-proof |
| Real-time analytics | None, no dashboard or reporting | Per-detector breakdown + revenue model |
| GDPR: no tracking cookies | No managed data handling either way | No tracking cookies, no visitor IDs, daily aggregates |

Where we win
The filter lists already know it
BlockAdblock's detection pattern is a known signature that EasyList and anti-adblock filter lists neutralise by name. AntiAdBlock Core votes across multiple independent signals and updates continuously, so no single filter rule blinds it.
Detection is only half the job
BlockAdblock tells you a blocker is present and stops there. AntiAdBlock Core adds a live dashboard, your real ad-block rate, recoveries and revenue at stake, plus a customizable recovery overlay, so detection turns into recovered revenue.
Maintained, not frozen
A free script is only as current as its last commit, and blockers change monthly. AntiAdBlock Core is kept current against the major filter lists, including uBlock Origin Lite under Chrome MV3.
The verdict
BlockAdblock is a fine way to learn how ad-block detection works, but as a production defence it is a fixed target the filter lists already neutralise. If you actually need to recover revenue, a maintained multi-vector detector with reporting is the difference between catching some blockers and catching almost all of them.

Frequently asked questions
Is BlockAdblock still effective in 2026?
Only partially. Because it relies on a single, well-known bait pattern, BlockAdblock is targeted directly by EasyList and the major anti-adblock filter lists, so on many visitors it no longer detects at all. It also has no handling for Manifest V3 blockers like uBlock Origin Lite.
Is AntiAdBlock Core free like BlockAdblock?
There is a real free plan, 10,000 detections a month with the full engine, so you can replace a free static script without paying. Paid plans are public, from $5 to $29.99/month, with no revenue share.
Can I just self-host a free anti-adblock script instead?
You can, but you take on the maintenance, and a single-signal script is easy to fingerprint and filter. A managed detector votes across many vectors and updates as filter lists change, which is what keeps detection working over time.
