Here's most of the stuff that I built myself (and that I still use on a regular basis):

- fae [https://h3rald.com/fae] · a minuscule find and edit utility

- h3 [https://h3.js.org] · an extremely simple javascript microframework

- hastyscribe [https://h3rald.com/hastyscribe] · a professional markdown compiler

- hastysite [https://hastysite.h3rald.com] · a high-performance static site generator

- herald [https://h3rald.com/herald-vim-color-scheme] · a well-balanced vim color scheme

- litestore [https://h3rald.com/litestore] · a minimalist nosql document store

- min [https://min-lang.org] · a small but practical concatenative programming language

- mn [https://h3rald.com/mn] · a truly minimal concatenative programming language

- nifty [https://h3rald.com/nifty] · a tiny (pseudo) package manager and script runner

- nimhttpd [https://h3rald.com/nimhttpd] · a static file web server
