Mwmbl - a new, experimental search index
The following was added to the Alternative search engines that are more respectful of your privacy page:
Mwmbl is an open-source search index geared toward technology, particularly sites linked on Hacker News. The project is described as "a non-profit, ad-free, free-libre and free-lunch search engine with a focus on useability and speed.". The bulk of the code is written in Python which seems like an odd choice regarding efficiency. Mwmbl apparently uses a hybrid crawling system composed of its own crawler plus an optional browser extension (source code) which acts as a distributed crawler, however it only crawls the top scoring sites on Hacker News which it uses as seed pages rather than allowing users to submit pages they visit, though users can submit pages manually right from the search results pages. As of 1-Nov-2023, Mwmbl has 105 million pages indexed.
Given the current focus on sites linked on HN, the programming language choice, and the apparent inability to submit selected sites using the browser extension, i don't think this one is going to last long without some changes, but what do i know.
