01Children and family
KidSpaceYou moved to Bali or Luxembourg with a child and have no idea where to take them. 2,500 places — schools, classes, playgrounds, shops, cafés — with the district, price, language of instruction, and one button that asks the owner about a trial class.upkidspace.id →BULUYou are on Bali and want a game of badminton or padel, but search only turns up hotels. Eleven halls and clubs with addresses, opening hours and a booking link.upbulu.alftech.space →02Life in Luxembourg
LuxFlashLuxembourgish is required for the Sproochentest and textbooks barely exist. 2400 words as cards: what you know comes back less often, what you forget comes back sooner.upluxflash.alftech.space →Luxembourg net payYou were quoted a gross figure and have no idea what lands in your account. Works it out by tax class and contributions, including the deductions nobody mentions. A detailed mode covers the awkward cases.upluxtax.alftech.space →Vivre ensembleYou are taking the Luxembourg citizenship test and do not know what to expect. 367 questions with every answer explained, and a mock exam in the real format — 40 questions in an hour, 28 correct to pass.upvivre.alftech.space →État des lieuxRecord the flat room by room before the keys change hands: numbered photos, meter readings, keys, both parties’ remarks — one FR/EN PDF to sign together. Nothing leaves your phone.uphandover.alftech.space →Letter decoderA letter arrives from the tax office or the commune in a language you do not read, and you cannot tell a fine from an advert. Paste the text and find out what is wanted, by when, and what happens if you are late — with a draft reply.uprazbor.alftech.space →Luxembourg homesThe portal shows fifteen listings and will not page further, so the rest of the market has to be prised out one filter at a time. This sweeps every price band onto one page: filter by price, bedrooms, region and type. Listings across the border in Saarland and Lorraine are marked as such.upimmo.alftech.space →
03Fix a file — nothing leaves your browser
CutYou filmed something long and need ten seconds from the middle — or a looping GIF that plays by itself. Cuts and builds it right in the browser; the file never leaves your machine.upcut.alftech.space →ShrinkYour photo weighs twelve megabytes and the form accepts five. Drop in a batch of images or video and get a zip of the right size. Nothing is uploaded anywhere — it is all recompressed in the browser, and GPS tags disappear along the way.upshrink.alftech.space →QRYou need to hand people a link, a Wi-Fi password or a business card, and all you have is a phone and a printer. Draws the code right on the page — links, passwords, contacts, in batches if needed; download as image or vector. Nothing is sent anywhere.upqr.alftech.space →MarkdownWrite Markdown and see the page as you type: tables, checklists, code. Save .md or a standalone .html, copy HTML, print to PDF — all inside your browser. No upload, no account, works offline.upmd.alftech.space →ConvertiPhone HEIC into JPG or PNG, JPG, PNG and WebP into each other, shrink to a size, metadata stripped — all inside your browser. No upload, no account, works offline.upconvert.alftech.space →TracesYou send a photo or a document to strangers, and along with it go the coordinates of your flat, your camera’s serial number and the author name inside the contract. Shows exactly what the file says about you, and strips it. All in the browser, nothing is uploaded.uptraces.alftech.space →PDFMerge PDFs, pull out pages, rotate, reorder, turn photos into a PDF and shrink a scan — all inside your browser. No upload, no account, works offline.uppdf.alftech.space →

Instructors bring their own CSV and get an unlisted paper for their class plus a report on what it still gets wrong.updfd.academy →CheckCVYou send your CV to dozens of openings and hear nothing back. Upload the file and a minute later get seven scores and a list of edits — what is wrong with the layout, which words are missing, and whether it survives the screening robots.upcheckcv.xyz →Invoice & actA Russian bank will not clear a payment from abroad on an invoice alone — currency control wants the full set.

06For developers
PrismaticYou need to look inside Elasticsearch and installing Kibana for five queries is too much. Shows the cluster, nodes, indices and shards, with a query console. You enter the cluster address; nothing is stored.upprismatic.alftech.space →JSON ToolsAn API answered with one line three screens long and something in it is broken. Formats it, points at the exact line and column of the error, minifies it back and converts it to CSV. All in the browser.upjson.alftech.space →Regex TesterYou wrote a regular expression and it does not match what it should. Highlights matches as you type and explains the pattern piece by piece. Whatever it could not parse it labels as unparsed, instead of pretending it understood.upregex.alftech.space →README MakerYou published a project with no description and cannot face writing one. Fill the form and get a finished README with badges, install and usage sections, straight to the clipboard.upreadme.alftech.space →PaletteYou need colours for a page and your eye has gone numb. Builds combinations — complementary, analogous, triadic — with a lock on the one you like, and hands them over as ready CSS and Tailwind variables.uppalette.alftech.space →
07Body and mind
LevelingLevel up a character with real actions: pick a class, get daily tasks, grow six stats. Experience comes from what you actually did — no button gives it to you. A missed day takes nothing away, and coming back after a break earns an achievement of its own.upsolo.alftech.space →Circadian rhythmsWhen to sleep, when to catch daylight, when to skip coffee — calculated from the time of day and your schedule. Nothing is measured: it is a model, and it says so.upcircadian.alftech.space →SerenityA mood and connection journal: a daily check-in, a log of real contact with people, gentle suggestions. Help goes through an international directory of crisis lines with a country picker.upserenity.alftech.space →DiaryAccount requiredYou want to write for yourself, but not into notes your cloud reads. Markdown entries, mood, tags, highlighted search, a calendar. Its own sign-in, and entries are encrypted with a key that lives only on this server.updiary.alftech.space →NeuroForgeTwelve exercises for attention and memory — N-back, Schulte tables, the Stroop test. Difficulty adapts to you, and what you forget comes back at the right interval.upneuro.alftech.space →KlothoTelegram botA small chat helper.@klotho_bot →Fats FighterTelegram botLogging meals by hand gets abandoned around day three. Photograph the plate and the calories and macros come back; you can also dictate it or simply type it. Daily, weekly and monthly summaries, and one missed day does not burn the streak.@fatsfighter_bot →
