Ad Blocker Dev Summit is back for 2026 — new location, old name
Some of you might notice something different about the title of this post.
You’re not imagining it: we’re bringing back the original name. What started in 2018 as the Ad Blocker Developer Summit later became the Ad-Filtering Dev Summit — but this year, we’re going back to our roots. Old-new name, same community.
And speaking of coming back: Ad Blocker Dev Summit 2026 is officially happening!
This year we're bringing it somewhere new: Copenhagen, Denmark, on November 3–4. ABDS 2026 is once again co-organized by AdGuard and eyeo, and it's free to attend.
Zoku Hotel, Copenhagen
Have something to share?
The call for speakers is open! If you’re working on something relevant to ad blocking or privacy protection, we want to hear from you.
Talk submission deadline: August 16, 2026.
After reviewing all submissions, we’ll get back to you in late August with decisions.
Just want to attend as a guest?

What is the Ad Blocker Dev Summit?
If you’re new here: ABDS (formerly Ad-Filtering Dev Summit) is the annual gathering for everyone who works on making the web a less intrusive, more private place — developers, filter list maintainers, browser engineers, privacy researchers and advocates, and everyone in between. Last year’s edition in Limassol brought together speakers from AdGuard, Brave, eyeo, Ghostery, Google, Malwarebytes, Mozilla, Opera, and more.
Watch the trailer from 2025:
And here is the full playlist of talks from last year’s summit.

We hope to see you in Copenhagen this November ;)
