Samefile is a browser-only duplicate finder that groups files by size and hashes the first N bytes using SHA-256. It scans a user-selected folder via the File System Access API and reports matches as size hash path lines. Optional include/exclude globs and a minimum size filter help narrow the search.

Launchpad Mini Toolkit connects to the hardware via Web MIDI and provides three modes—Debug, Blob Tap, and Snake—for exercising or experimenting with the grid. The page mirrors pad activity on a canvas, streams MIDI log messages, and even lets you spawn animated blobs or run a playable snake game while syncing the Launchpad lights. Mode controls and hints switch dynamically so you can toggle behaviors without leaving the browser session.

Select any five cards (including the Joker) from the grid, and the advisor computes the top EV selections for which cards to keep or discard. The interface also accepts an optional Gemini API key so you can upload or photograph a hand and let the AI transcribe the five cards automatically. Results highlight the best three plays, show each card as part of the original hand, and score them using the in-page Jokeripokeri payoff logic.

Jokeripokeri Trainer deals a hand of five cards, lets you tap the ones you want to keep, and then shows message feedback once you press the deal button to rerun the next hand. The sidebar keeps running totals for games, winnings, average payout, and a separate optimistic strategy tracker so you can compare your selections to the theoretical expectation. An expandable table below documents the optimal combinatorics while the CSS-only cards keep everything sharp-looking on both desktop and mobile viewports.

Type a decimal number, pick how many digits of accuracy you need, and the page shows the nearest rational approximations up to that precision. It is a lightweight converter that keeps refining fractions as you increase the target decimal places and displays them in a monospaced answer box. No backend is involved—everything is done in the browser using the tiny script bundled in the HTML.

Piano Trainer draws a clean staff and piano keyboard in SVG, then prompts you with notes to emulate using left or right hand, selectable via the floating controls. Touch or click anywhere on the piano area and the script highlights the notes on the staff, plays the target, and advances when you hit each of eight notes correctly. The experience is optimized for touch devices with a fixed control bar, so you can practice bass (left) and treble (right) ranges purely in the browser.

Firefighter: Gingerbread Defense is a canvas-based action game where you aim a cannoniac water stream to quench spreading fires before they overwhelm the gingerbread village. Difficulty presets change how fast fires grow, how much water/health you have, and how aggressive shooting stars or fire spreads become, while on-screen gauges keep you aware of health, water, angle, and power. The UI includes start/game-over overlays, controls help, and feedback so you can adjust angle/power, keep firing, and survive long enough for bonus points.

Nordic Christmas Night layers WebGL aurora ribbons, a scene canvas, and a snow canvas to render a calm holiday screensaver entirely in the browser. The aurora shader demos simplex noise, fbm, and color blending to create flowing bands, while other layers add the silhouette scene, snow effects, and faint help hints for interaction. Everything is fullscreen, cursor-free, and tuned for atmosphere so you get a looping northern lights display without any manual input.

Drop a ZIP file that contains JPEG/PNG/GIF/WebP images anywhere on the page and the client decompresses it with fflate, filters to supported extensions, and populates a responsive thumbnail grid. Each thumbnail lazily loads a blob URL, and clicking one opens a fullscreen viewer that supports fit and pointer-locked 1:1 navigation plus keyboard or wheel-based image stepping. The app keeps your ZIP processing local, shows an extractor spinner while indexing contents, and overlays contextual tips for zooming and panning.

This ZIP Image Viewer decompresses archives entirely in the browser with fflate, lazily creating thumbnails as it filters supported image extensions, and it exposes a sticky top bar once content loads. Grid tiles overlay names, file sizes, and thumb placeholders while a fullscreen viewer supports fit/1:1 toggling, pointer-lock panning, and keyboard navigation between images. Drop hints, drag-over styling, and a reset button keep interactions discoverable, so it behaves like a polished photo review utility without ever uploading your files.
