Open Source Tooling for Underserved Developer Workflows Getting Real Traction
Two Show HN posts landed well today with very similar reception. A WYSIWYG TikZ editor for LaTeX figures got immediate, warm response from researchers and STEM students who have wanted exactly this for years. FUTO Swipe, an open swipe typing model, got positive engagement from people who rely on swipe keyboards and had no open alternative. Both fill gaps that exist because the dominant tools are proprietary and closed.
The FUTO Swipe thread is particularly interesting because FUTO has a stated mission around software freedom and has been building a portfolio of open alternatives to closed consumer software. Commenters noted feature requests (word history for custom words) but the reception was genuinely warm rather than the usual 'why not just use X' skepticism.
The TikZ editor is a narrower but real win: it solves a specific, painful workflow for a technical audience that has been copy-pasting StackOverflow TikZ snippets for twenty years. These are not viral consumer apps. They are tools that will be quietly used by thousands of people who will tell no one.
So what?
The most durable open source projects often start by solving a specific, painful workflow for a technical audience that nobody else bothered to serve because the market looked too small. If you are looking for a project to build, start by listing workflows where the best available tool is either closed, expensive, or just old. The TikZ editor and FUTO Swipe both found their audience immediately because the audience had been waiting.
