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.

OpenCVE lets you search the CVE you want filtered by vendor, product, CVSS or CWE. Synchronized with the feed provided by the NVD. So each CVE displays the standards you already know (CVE, CPE, CWE, CVSS). You can then subscribe as many vendors or products as you want, and you will be notified as soon as a CVE concerning them is published or updated. Your custom dashboards and reports only include the CVEs associated with your subscriptions, and you can filter the list by keywords of CVSS score. OpenCVE keeps track of the changes, so you can find the history of your alerts in your Reports page. Can be self-hosted if you're concerned about leaking information outside of your organization.
