KoalaStuff

I read an article about "Dopamine sites" in South Korea (sites with fake shopping carts and fictional parcel tracking designed to release dopamine without spending money). I thought the idea was hilarious and wanted to see how hard it would be to build, while also testing Svelte as an alternative to Astro.

Flatland TD was heavily inspired by the game 'The Tower'. It really annoyed me that it wasn't playable on PC, which is why I turned it into a responsive web app. Also, the pay-to-win system of the developers got on my nerves – they simply became way too greedy.

KoalaSync was born out of frustration that popular watch party alternatives like Teleparty do not support self-hosted platforms (e.g., Emby). I wanted to create a privacy-first solution that remains permanently free, ad-free, and fully self-hostable.

Tired of searching for a new, working graphical user interface every time I wanted to use yt-dlp, I decided to build my own clean, native desktop UI.

While playing Cookie Clicker, I wanted an easy, safe way to quickly automate clicks without having to install untrustworthy browser extensions or external scripts.

I found existing cookie managers to be bloated or invasive. I wanted a minimal, privacy-focused extension that provided only the necessary tools for managing cookies locally.

Playing two characters in Flyff Universe manually is tedious. I built this extension to automate the boring support tasks by syncing inputs between tabs.

Modern movies often have extreme volume fluctuations between quiet dialogue and loud action scenes, forcing constant volume adjustments. KoalaSound was built as a proof of concept to solve this, with the goal of eventually integrating it directly into KoalaSync.

I needed a personalized new tab page that immediately links to all my key projects and servers to speed up my daily workflow. It also shows the local weather conditions at a glance.

I was frustrated by the chaos of keeping hundreds of unsaved tabs open in Notepad++ just to store SQL queries and code snippets. Since the popular alternative 'snippet-box' hadn't been updated in years, I built KoalaSnippets as a modern self-hosted replacement.

KoalaWeb started with the idea of a synchronized online timer to coordinate regular 30-minute breaks with a friend without having to ask how much time was left. It later expanded to include League of Legends esports trackers, betting games with play money, and other fun features.

This project was built as a proof of concept. After seeing someone on Reddit charge money for a chat mockup generator, I wanted to prove that a similar tool could be built in just one or two hours using a free AI model (DeepSeek).

I wanted a small, fast Markdown workspace that keeps drafts local by default and does not require accounts, sync services or a heavyweight writing suite.

I wanted to create a privacy-focused RSS reader and aggregator that allows me to simply open a single page and scroll through all my news feeds in one place without any tracking.

KoalaWorld was a proof of concept to evaluate the capabilities of local AI models. I wanted to see if they could generate a smooth WebGL 3D rendering of Earth that visualizes real-time geospatial data from various open APIs.

To understand why users uninstall KoalaSync, I needed a privacy-focused survey tool. I wanted to avoid paying external providers and, most importantly, keep my users' data safe by not redirecting them to third-party platforms with questionable privacy policies.

I wanted a personal finance tool that doesn't connect to banks or rely on external services. Every existing solution either requires full bank API access or runs on someone else's servers. KoalaFinance is my attempt at a self-hosted, encrypted, manual-budgeting alternative where only the user holds the keys.

Existing TTRPG campaign tools are either bloated with features I don't need or require accounts and cloud storage. I wanted a simple, local-first notebook that works offline, keeps player data private, and optionally syncs when I choose — without lock-in or subscriptions.
