Themer

A Bluetooth transfer hub for the browser, in Portuguese, that works fully offline. It centers on transfers between devices over Bluetooth and adds a public terminal, connection logs, and a large UUID reference for working with Bluetooth services. Useful for tinkerers exploring Bluetooth on the web.

Lightning-fast color scheme generator. Press spacebar to generate palettes. Lock colors you like, adjust hues, export to CSS/SVG/PDF. Millions of designers use it daily. Palettes carry contrast ratios, which makes it usable for accessibility checks and not only for inspiration.

A small color picker utility packaged as a Progressive Web App. Its own description labels it a test app, and its page title, 'Dastur UZ', suggests an Uzbek developer's project. Best treated as a simple demo for picking colors in the browser rather than a full product.

Create beautiful screenshots of your code snippets. Customizable themes, backgrounds, and window decorations. Share code visually on social media — like Carbon.sh but installable. Syntax highlighting follows the language you pick rather than a screenshot, so the result stays legible when scaled down.

Fast, offline, and free documentation browser for developers. Search 100+ docs in one web app including HTML, CSS, JavaScript, PHP, Ruby, Python, Go, C, C++, and many more.

Open-source product analytics, session replay, feature flags, and A/B testing. Self-hostable alternative to Mixpanel/Amplitude — know how users really use your product. Session replays link to the events that triggered them, so a funnel drop can be watched rather than inferred.
