A toolkit for CDX indices such as Common Crawl and the Internet Archive's Wayback Machine
Summarize web archive capture index (CDX) files.
Python tools to retrieve text from CommonCrawl WARC files based on cdx index.
Fetch and normalize parameterized URLs from the Wayback CDX API (OSINT, inspired by ParamSpider).
Enables Mac roundtrip editing for ChemDraw scheme-contaning PowerPoints made in Windows
Zero-install, server-preserving web archiver and ISO 28500 forensic engine for offline replication and digital preservation.
View cdx and warc files, caching them locally as needed
A web crawler built from scratch in Python, one concept per stage: frontier, robots.txt, politeness, async workers, dedup, rendering, freshness, a distributed frontier, WARC archives, a CDX index and replay. Thirteen stages, 222 tests, verified against a corpus that declares its own ground truth.
Unofficial agent skills for the Internet Archive: CORS-aware HTTP/API access, browser widgets, Wayback/CDX and degraded-mode handling, per-mediatype metadata patterns. Complements internetarchive/internet-archive-skills.
The solution to extend the deadline for the virtual machines on CDX.
Wayback Machine scraper for Python and the command line: archived snapshots of a URL or a whole domain with capture time, HTTP status, MIME type, size, content digest and playback links, filtered by date range, as JSON or CSV.
