WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
Scantron looks pretty awesome! liwasc isn't using nmap internally, the entire network scanner part (https://github.com/pojntfx/liwasc/blob/main/pkg/scanners/nod...) is <150 SLOC and the port scanner is <250 SLOC. Go has some really nice low-level networking APIs, especially when combined with `gopacket`.
I haven't really tested it on anything larger than /28 - it should probably work on larger ones as well though (it limits the maximum concurrent port & network scans so that ulimit etc. aren't an issue) :)
Glad to see more open source options (I develop and maintain Scantron https://github.com/rackerlabs/scantron/) when it comes to network scanning! Appreciate your contribution to the community.
So you're not using nmap under the hood?
What's the largest IP space you've tested it on so far?
