For my Chrome extension Checkbot (https://www.checkbot.io/ https://www.checkbot.io/), I got the idea when I was working as a freelance web developer on several websites at a time. I was doing a lot of manual checks for SEO, speed and security best practices, and wanted something to automate the process for me. I wanted a tool that could check many pages at the same time, check for many best practices, check localhost sites, check unlimited sites and let you recheck whenever you made a change. I couldn't find one at the time so I made my own. I showed Checkbot in its early stages to several people I knew and after I had the feeling enough other people would find it useful I spent time packaging it into something I could try to sell. This included polishing the UX, creating a website and writing a web best practices guide which was a lot of work. I launched a free beta on reddit and Product Hunt which I got a lot of feedback from. After refining the product some more, I launched payment plans and now I'm slowly growing a paid customer base.
