Open-source Linux games, tools and coding agents

Seven free projects I have built, mostly small Linux-native C++: two games, an artificial-life rat, two coding-agent harnesses, a local finance assistant and a disk-cleanup app. Each has its own page with requirements, how to run it and how it works; the code lives on GitHub, so you can clone it, read it and run it locally.

Game · RTS

One Hour

A compact skirmish real-time strategy game in the spirit of Command & Conquer: Generals – Zero Hour. One map, two armies (Cyber and Clanker), you against one to three AI opponents. No campaign, no multiplayer.

C++
Linux

Requires

g++ and make
SDL2 runtime (libsdl2-2.0-0); SDL2 headers are vendored

Get it

Clone the repository, then run ./run.sh.

Game · arcade

Mini Space Shooter

A pixel-art space shooter written in C11 and C++17 with endless levels. Fixed-capacity pools and its own online learners adapt enemy movement and tactics to how you fly, with hard limits on raw difficulty.

C / C++
MIT licence
Linux (Wayland and X11)

Requires

build-essential, libx11-dev, libxext-dev
Optional: SDL2 runtime for native Wayland

Get it

Clone the repository, then run ./run.sh.

Artificial life · ML

Self Improving Rat

A persistent artificial-life rat in a procedurally generated maze: a recurrent reinforcement-learning agent with homeostasis, curiosity and episodic memory that saves its whole state between runs. No GPU, no ML framework, no network.

C++20
Linux (tested on Ubuntu 26.04)

Requires

cmake 3.16+, g++ and make or ninja
libsdl2-dev (the test suite needs no SDL)

Get it

Clone the repository, then run ./run.sh.

Developer tool · coding agent

PocketHarness

A deliberately tiny, Linux-native coding-agent harness in a single C++ binary: a chat TUI, slash commands and autonomous goals, with no SDKs, plugins or MCP layer. Linux does the general-purpose work.

C++20
MIT licence
Linux x86_64

Requires

g++ (C++20), make and curl
Optional: Chrome, FFmpeg, llama.cpp for screenshots, video and the local judge

Get it

Source and a tagged release are on GitHub; the README has the install steps.

Developer tool · coding agent

YunusPi

An independently maintained coding agent harness with its own core (historically derived from Pi 0.85.1): persistent project memory, bounded subagents, an advisory layer and safety hooks. You bring the model provider.

JavaScript
MIT licence
Linux
Windows via WSL2 Ubuntu
macOS via an Ubuntu VM

Requires

Node.js 22.19+ and npm
git, curl, bash, ripgrep, python3, build-essential, bubblewrap

Get it

Source and a tagged release are on GitHub; the README has the install steps.

Desktop app · finance

Finny

A local-first personal finance assistant with a native desktop window. It answers rates, inflation, FX and calculator questions with a Naive-Bayes classifier and fuzzy matching, not a language model, and cites public sources.

Rust
Linux (Ubuntu)

Requires

Rust stable toolchain (run.sh can install it via rustup)
X11 or Wayland client libraries

Get it

Clone the repository, then run ./run.sh.

Desktop app · disk cleanup

Dataclean

A small GTK 4 app that shows where your disk space goes and finds byte-identical duplicates and forgotten leftovers. Nothing is deleted: files go to the Trash after a confirmation, with checks right before each move and an undo.

C
MIT licence
Linux (GTK 4)

Requires

gcc and make tools (build-essential)
GTK 4 runtime; run.sh fetches the dev headers locally if missing

Get it

Clone the repository, then run ./run.sh.
