2 of my most used web apps are ones I made (technically 3 but the 3rd is a platform service that handles stuff common to all of the services that run on it, there's 5 currently)
1 is a sort of a virtual notebook where I put things I want to remember. Things like guides for setting up new services on top of that platform service. Or random 1 line commands that I don't quite use enough to remember but still need to. Page content in this app is stored in encrypted Markdown files, the metadata (ie the title, publish date, etc) is stored in a local MongoDB instance. It has a feature where you share individual pages publicly if you want, but otherwise pages are viewable only by their original creator. Server is Go, frontend is Angular 10. I don't remember how long it took to build as it started as something else and I kinda reset the development half way through. Probably a few weeks, but I also wasn't constant working on it, so probably longer.
2 is a thing I built out of frustration with my self-hosted Gitlab instance constantly OOM-ing the VM it was on and crashing. It has like a tenth or less of the functionality of Gitlab, but also uses substantially less memory and CPU and does exactly what I want so hasn't seen much if any further development. Also Go for the server and some even older version of Angular for the frontend.
