StreetPass is a browser extension that helps you find your people on Mastodon. Users verify themselves by adding a custom link to their personal site. StreetPass lets you know when you've found one of these links, and adds them to your StreetPass list. Browse the web as usual. StreetPass will build a list of Mastodon users made up of the websites you go to.
Available for Chrome and Firefox.
This is an independent DIY search engine that focuses on non-commercial content, and attempts to show you sites you perhaps weren't aware of in favor of the sort of sites you probably already knew existed.
The software for this search engine is all custom-built, and all crawling and indexing is done in-house.
This search engine isn't particularly well equipped to answering queries posed like questions, instead try to imagine some text that might appear in the website you are looking for, and search for that.
Where this search engine really shines is finding small, old and obscure websites about some given topic.

Selfauth is a self-hosted Authorization Endpoint used to login with a personal URL (as Web sign-in) via IndieAuth.
Requires only two files in a subdirectory, index.php and config.php. Does not require a database, writes its own config file. Then hide a link like this in your site's <head></head> block:
<link rel="authorization_endpoint" href="https://example.com/auth/" />
When logging into a site that supports it, your username is the URL of your website (https://example.com/) and your password is the password you gave when you set up selfauth.
The indieweb is a movement in which people own their data, and run their own applications rather than other people's walled gardens. content is there and isn't censored arbitrarily. federation with some or all services is done with interoperable-by-design protocols and data formats. User interaction (replies, likes, stuff like that) are also federated back to your site(s).
