Small things, each on its own path. All of them run entirely in your browser — no accounts, no servers, nothing uploaded. Close the tab and nothing of yours went anywhere.
Base64, JWT decoding, UUIDs, hashes, a regex tester, cron parsing, timestamps, JSON formatting and a text diff. The pile of things you normally paste into somebody else's ad-riddled website.
/wortOne five-letter puzzle a day, the same for everyone, derived from the date. Six guesses, a streak that survives reloads, and a spoiler-free result grid to share.
/kaomojiA searchable pile of (=^･ω･^=) and relatives. Type to filter, arrow keys to move, enter to copy. No network requests once the page has loaded.
/nyanifierText in, cat nonsense out, in four escalating levels. Deterministic — the same text always transforms the same way. Usable as a library and a command line tool too.
/cafeAn idle game made of numbers and curves: twelve tiers of staff, upgrades that multiply each other, synergies, achievements, a bean shop for prestige currency and earnings while the tab is shut.
/casinoSlots, roulette and blackjack with chips that cannot be bought and refill for free. The odds are the real ones, each game shows its true house edge, and the bank panel tracks what you have actually got back against it.
/testdataFixtures from a seed: names, addresses, IBANs that pass a real mod-97 check. JSON, NDJSON, CSV or SQL. The settings live in the URL, so the link regenerates the exact same rows instead of committing a blob.
/whenA day laid out across everyone's time zones, with the hours nobody has to be awake at 4am for picked out. Daylight saving and half-hour offsets included; the whole plan is the link.
