ShareX

ShareX is a wildly explosive, fiercely independent open-source disruptor that mathematically annihilated the "Power User Screenshot" market. It is a completely free, ridiculously complex workflow engine masquerading as a screenshot tool. It is the absolute weapon of choice for elite software developers and sysadmins who mathematically demand a tool that captures a screen, mathematically blurs out a password, uploads it to an AWS S3 bucket, and copies the URL to the clipboard in 0.5 seconds.
