I built two dozen single-file HTML tools that run offline and need no back end
I'm a teacher who started making my own productivity tools. I was tired of subscriptions and paywalls. Every tool is a single HTML file. Download it, open it, data stays local. No server, no login, no API calls. Started as a personal project but I've now shipped habit trackers, journals, planners, invoice generators, and a bunch of teaching tools. Curious what HN thinks about this approach to software. 4 comments on Hacker News.
