Open-source apps that replace Google Search and Bing
SearXNG is a free search tool that shows results from many other search engines in one place, without tracking or profiling users. It is for people who want to search the web privately and can run it themselves or use a public instance.
YaCy is a search engine you run yourself, with its own index of web pages. It suits people who want private search or a search tool for an intranet.
Librengine is a privacy-focused web search engine that crawls websites and searches its own index instead of using large commercial search services. It is aimed at people who want to run a private search site, and the README says the project is no longer maintained.

Fix the list itself
A project or closed app missing from this list, or a mistake on it? These open a short form on GitHub, and a mod reviews it. To say what a project can't do, use What's missing.
About this page
Replaces fully means it does the main job of these apps; Replaces partly means it covers some of it.
Licenses: every project here uses an open-source license (what each one means). Open core means some parts are paid or under another license.
GitHub stars are shown for reference. They measure popularity, not whether it replaces anything.
Verified means r/TrueOpenSource mods checked it: open-source license, maintained, and it really does the job.
