I built a little browser game to practice Vim commands
I made hjkl to help myself remember Vim commands. It’s a little browser game you can play when you want to unwind and get a bit of Vim practice in.There are still a lot of commands I want to add, but I hope someone finds it useful in the meantime :)

The pain of remembering Vim commands is real but niche, the game fills a small gap, few would pay for it, and it is easy for one person to build.
Value Equation
Dream outcome and how likely it feels, against the time and effort it costs.
The value to users is limited and mostly for casual practice, making it hard to justify strong demand or monetization.
One-Person Business
Curiosity pull, identity fit, and a path from free value to paid for a solo creator.
The idea targets a small, specialized audience with moderate engagement potential but lacks clear monetization or growth paths.
Viral Frameworks
Hook strength, shareability, and how cheaply it can be tested.
The concept is simple and feasible but has low market size and unclear customer acquisition strategies.
Builder Lens
Evidence the problem exists, timing, defensibility, and a model that fits on a napkin.
The product solves a niche problem with a minimal viable solution but lacks evidence of strong user traction or scalable business model.

Every CEO and CFO change at US public companies, live from SEC
Built this solo. It watches SEC filings for executive and board changes, extracts the data, and shows it in real time. 2,100+ changes in the last 30 days. The comp data is interesting: average new CEO total comp is $8.4M across 284 appointments. The /explore page is fully open, no login needed.

µJS, a 5KB alternative to Htmx and Turbo with zero dependencies
I built µJS because I wanted AJAX navigation without the verbosity of HTMX or the overhead of Turbo.It intercepts links and form submissions, fetches pages via AJAX, and swaps fragments of the DOM. Single <script> tag, one call to `mu.init()`. No build step, no dependencies.Key features: patch mode (update multiple fragments in one request), SSE support, DOM morphing via idiomorph, View Transitions, prefetch on hover, polling, and full HTTP verb support on any element.At ~5KB gzipped, it's smaller than HTMX (16KB) and Turbo (25KB), and works with any backend: PHP, Python, Go, Ruby, whatever.Playground: https://mujs.org/playgroundComparison with HTMX and Turbo: https://mujs.org/comparisonAbout the project creation, why and when: https://mujs.org/aboutGitHub: https://github.com/Digicreon/muJSHappy to discuss the project.
