Nullism

Basic Query Builder, a simple SQL query builder for Go. High performance, used in production by several companies, and 100% test coverage. Included in Awesome Go.

A simple top-down shooter using Construct 2 and later Phaser. Inkscape was used for vector graphics. Gameplay was simple. A few thousand active players at peak. Dependencies that I included remotely stopped working and I haven't been keen on fixing it as nobody still plays it.

A simple ReST API framework for Python built on WSGI. Very fast compared to Flask / Bottle. Deprecated due to so many better alternatives these days.

A simulation of N agents, all starting with the same amount of "wealth" and buying goods and services in a random manner. The simulation demonstrates how wealth gaps form from a completely even playing field. Includes settings like investments and wealth redistribution.

A simple incremental game inspired by Breaking Bad. Written in vanilla JS & CSS. Over 1 million unique players before Google rate limited the analytics. Originally used Python Flask to render but when it went "viral" I had to switch to a static site to handle the load, served via Apache (MPM).

An Android App version of Clicking Bad. Used Phonegap to bundle. Note: Google removed this in 2014 due to "promoting drug use" though I disagreed my appeals failed.

A 3D (2D pathing) tower defense written in C# and Unity. Published to Facebook via the Unity Web Player, which is now deprecated. Had a few thousand players at peak. The innovative piece (at the time) was that the enemies could attack your towers. Used Blender for the models and Gimp for UV texturing.

A simple static site generator written in Python. Became mildly popular but things like Hugo have taken over. The interesting feature was the built-in search index generator (keyword frequency) that allowed static client-side searching.
