About

Crawler.sh is a fast, local-first web crawling and SEO analysis tool that enables users to crawl entire websites, extract clean content, and export structured data in seconds. It is available as both a command-line interface and a native desktop application, giving developers and SEO professionals flexibility depending on their workflow. It performs high-speed concurrent crawling within the same domain, with configurable depth limits, concurrency controls, and polite request delays suitable for large sites. It automatically extracts the main article content from pages and converts it into clean Markdown, including metadata such as word count, author byline, and excerpts. It also runs sixteen automated SEO checks per page to detect issues like missing titles, duplicate descriptions, thin content, long URLs, and noindex directives. Results can be streamed or exported in multiple formats, including NDJSON, JSON, Sitemap XML, CSV, and TXT.

About

LexVec is a word embedding model that achieves state-of-the-art results in multiple natural language processing tasks by factorizing the Positive Pointwise Mutual Information (PPMI) matrix using stochastic gradient descent. This approach assigns heavier penalties for errors on frequent co-occurrences while accounting for negative co-occurrences. Pre-trained vectors are available, including a common crawl dataset with 58 billion tokens and 2 million words in 300 dimensions, and an English Wikipedia 2015 + NewsCrawl dataset with 7 billion tokens and 368,999 words in 300 dimensions. Evaluations demonstrate that LexVec matches or outperforms other models like word2vec in terms of word similarity and analogy tasks. The implementation is open source under the MIT License and is available on GitHub.
