Webrecorder pywb 2.6

Web Archiving Tools for All

View the full pywb documentation

pywb is a Python (2 and 3) web archiving toolkit for replaying web archives large and small as accurately as possible. The toolkit now also includes new features for creating high-fidelity web archives.

This toolset forms the foundation of Webrecorder project, but also provides a generic web archiving toolkit that is used by other web archives, including the traditional "Wayback Machine" functionality.

New Features

The 2.x release included a major overhaul of pywb and introduces many new features, including the following:

  • Dynamic multi-collection configuration system with no-restart updates.
  • New recording capability to create new web archives from the live web or other archives.
  • Componentized architecture with standalone Warcserver, Recorder and Rewriter components.
  • Support for Memento API aggregation and fallback chains for querying multiple remote and local archival sources.
  • HTTP/S Proxy Mode with customizable certificate authority for proxy mode recording and replay.
  • Flexible rewriting system with pluggable rewriters for different content-types.
  • Standalone, modular client-side rewriting system (wombat.js) to handle most modern web sites.
  • Improved 'calendar' query UI with incremental loading, grouping results by year and month, and updated replay banner.
  • Extensible UI customizations system for modifying all aspects of the UI.
  • Robust access control system for blocking or excluding URLs, by prefix or by exact match.
  • New in 2.6: Access Control embargo and http-header control access settings.
  • New in 2.6: Support for localization and multi-language deployment.

Please see the full documentation for more detailed info on all these features.
