Parser for Adblock Plus rules
Decision gist · record as of 2026-08-14
No. The package is abandoned (last commit 2019, last release 2016) with no active maintenance. While it has low install friction and no security vulnerabilities, the lack of updates means it may not handle modern Adblock Plus syntax changes or work reliably on current Python versions. Use only if you have a legacy codebase already depending on it.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- pyre2 library is optional but highly recommended for performance; it requires C++ re2 library installed on the system.
- Low install friction with no runtime dependencies.
- However, the package is abandoned as of 2019 with no active maintenance, and the last release was in 2016.

What it is and what it does
adblockparser is a Python library for parsing and applying Adblock Plus filter rules. It reads filter rules (either manually written or from sources like EasyList) and provides a method to check whether a given URL should be blocked according to those rules. The library handles both simple wildcard-style filters and more complex rules with options like domain-specific matching and script-type filtering.
The package creates large regex patterns internally to match filters efficiently. It optionally integrates with pyre2 for dramatic performance improvements—potentially over 1000x faster for large filter lists. Without pyre2, it falls back to Python's standard re module. Rules with options are evaluated individually, which can be slower with thousands of such rules, but the library provides configuration options to optimize this scenario.
Use it for
- Build a web scraper or crawler that respects Adblock Plus rules to avoid fetching blocked resources
- Implement ad filtering in a browser extension or application using standard filter lists
- Filter URLs in a content management system or proxy to block ads and trackers based on EasyList rules
- Test URL filtering logic by programmatically checking whether specific URLs match filter rules
- Load and apply custom Adblock Plus filters to control which domains or resources are accessible
