A meta-search engine a little like Searx. Not as featureful, not many features, but for something quick and dirty to just get stuff done it seems to do the job. No Javascript. Self hosted. Strips tracking codes out of URLs it finds. Lightweight - no Composer stuff, all self contained. Has an API but not REST.
Free and Open Source Machine Translation API, entirely self-hosted. Unlike other APIs, it doesn't rely on proprietary providers such as Google or Azure to perform translations. Instead, its translation engine is powered by the open source Argos Translate library.
Supports per-user limit quotas, e.g. you can issue API keys to users so that they can enjoy higher requests limits per minute (if you also set --req-limit). By default all users are rate-limited based on --req-limit, but passing an optional api_key parameter to the REST endpoints allows a user to enjoy higher request limits. To use API keys simply start LibreTranslate with the --api-keys option.
There are also F/OSS mobile clients for Android and browser plugins.
This tool aims at accumulating javascript files from a given set of subdomains to discover hidden API endpoints. It swims through JS files to find more JS files. It also creates a target-specific wordlist from the JS-files for further content discovery, appends new subdomains discovered from the JS files to the user specified subdomain file, and dumps all the discovered JS files neatly in a folder for static analysis.
It seems to set up a bunch of other tools and grinds up their output.
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.

Resty provides a simple, concise shell interface for interacting with REST services. Since it is implemented as functions in your shell and not in its own separate command environment you have access to all the usual shell tools. Cookies are supported automatically and stored in a file locally. Most of the arguments are remembered from one call to the next to save typing. It has pretty good defaults for most purposes. Additionally, resty allows you to easily provide your own options to be passed directly to curl, so even the most complex requests can be accomplished with the minimum amount of command line pain.
Implemented as a shell script that you source: . /path/to/resty
Basically, Resty lets you treat HTTP requests to a REST API like a series of CLI commands.
