WhatsApp bot that monitors a team group chat and sends escalating standup reminders with a weekly leaderboard

ClimateWatch
75 years of Indonesian climate history turned into plain visual answers for 75 cities — free, no login

Chipfire
A browser game of chain-reaction explosions — play a friend on another device with no server, no account, and no backend anywhere

Falak
Hijri calendar, prayer times, and qibla direction computed from real moon/sun astronomy — every verdict shows its numbers

Faraid Visualizer
Islamic inheritance calculator that shows the full reasoning — every share traced to a Qur'an, hadith, or Indonesian state-law citation, with KHI and classical Syafi'i run side by side

GempaWatch
A free public site that tells anyone in Indonesia how earthquake-prone their own area is — using 57 years of official records, not just the latest tremor

Quranlytics
Quran reader with a full analysis layer — word/root frequency, structural patterns, and semantic search across 6,236 verses

Lontara
A free tool for reading and writing the Bugis Lontara script — and, crucially, showing every possible reading when the script itself doesn't say which word is meant

Sanad
Hadith reader and analysis platform — interactive narrator-chain graphs, corpus analytics, and honest scholar-attributed grading

Congklak
A browser congklak that lets you pick which region's rules you play by — each ruleset cited to its source — against a friend, the computer, or someone on another device

Myers Visualizer
An interactive tool that plays back, step by step, what happens inside `git diff` — and why it sometimes blames the wrong line

Git Rebase Simulator
A safe sandbox to practise the scariest parts of Git — rebase, hard reset, force-push — and watch what actually happens to your commits, with real content-addressed hashes

Stemmer Visualizer
Takes an Indonesian word and shows, step by step, how the standard algorithm strips it to its root — including the steps it abandoned, and the cases where more than one root is genuinely possible

Raft Simulator
Teaches how a fleet of servers agrees on one shared record — and lets you switch off individual safety rules to watch the system break in exactly the way the rule was there to prevent

Terbilang
Turns Indonesian numbers into the words required on invoices and cheques — 1.500 becomes seribu lima ratus — and reads them back, correctly, at any size an accounting system can throw at it

Selapan
A Javanese calendar that converts any date into its traditional reckoning — and, unlike every other site that does this, shows the arithmetic behind each number and cites where the reference points came from

Spectrogram
Turns sound into a picture in real time — speak, whistle or play into your mic and watch which pitches are present — with the underlying mathematics written from scratch, not borrowed from the browser

Gizi Masakan
Tells you the nutrition of Indonesian dishes — and shows the exact recipe it used to get that number, so you can correct it if your kitchen does it differently

KPR Simulator
A free, ad-free Indonesian mortgage calculator that shows what happens after the bank's fixed-rate period ends — the part every other calculator leaves out — and the exact floating rate at which your instalment stops being affordable

Sketch Lab
Shows how databases store approximate answers about huge amounts of data in a tiny fixed amount of memory — with the exact, slow version running side by side so you can watch how wrong the approximation actually is

Isolation Anomaly
Hand-build two overlapping database transactions, watch exactly where they corrupt each other's data, then re-run the identical scenario against PostgreSQL, MySQL, SQL Server and Oracle to see the same code produce four different outcomes

Congestion Lab
Shows, packet by packet, how the internet decides how fast to send data — and why your video call stutters the moment someone in the house starts a download

Angklung Simulator
A browser angklung that models the instrument's real constraint — one angklung plays exactly one note, so a song has to be shared across a room of people — with every sound computed from a physical model of a bamboo tube, not played back from a recording

Tanggal Merah
An Indonesian holiday planner that shows the year's public holidays and works out exactly where to spend annual leave for the longest stretches off — while making explicit the rule most people get wrong: whether cuti bersama is charged against your leave

Nusantara Languages
An interactive map of Indonesia's 726 languages, coloured by family, with a genealogical tree wired to the map — hover a branch and every territory in that group lights up, and the other way around

Tide Analysis
A site that watches the tide, does the math itself from raw sea-level readings, and tells you honestly when it doesn't have enough data to trust its own answer — instead of quoting numbers someone else calculated

Anatomi Rupiah
A bilingual explainer that teaches how to spot the genuine security features on Indonesian banknotes — using original illustrated diagrams instead of photos of money, because photographing currency for this is legally restricted

Zero Shadow Day
A free tool that tells anyone in Indonesia the exact two days a year the sun stands directly overhead where they live — and lets them re-run Eratosthenes' 2,200-year-old measurement of the Earth's circumference with a partner elsewhere in the country

Pola Hujan
Indonesia doesn't have one rainy season — it has three rainfall patterns, and this atlas derives them from satellite data instead of copying the official map

Bentuk Kota
Measures the street layouts of 33 Indonesian neighbourhoods twice — once by car, once on foot — because the standard academic metric only sees the driving network and misreads a kampung completely

Periodic Lens
An interactive periodic table that explains why the table has its famous shape — by animating the physics rule that builds it — and shows which elements Indonesia digs out of the ground as a share of world production

Rumah Adat Nusantara
An interactive collection of 35 traditional Indonesian buildings, each computed from the cultural rules that govern it — a household's rank, a family count, a body measurement — so changing one number rebuilds the structure in front of you

Query Planner
A browser-based SQL query planner and executor that shows every plan a database considered — not just the one it picked — and puts its estimate next to the truth at every step, so you can see exactly where and why it guessed wrong

Mixed Traffic Simulator
A browser simulator of Indonesian motorcycle-dominated traffic that runs the controlled experiment no field study can — proving the standard "one motorcycle equals 0.25 cars" planning constant is an artefact of how it was measured, not a fact about traffic

Anatomi QRIS
An interactive explainer that takes any text — including a real QRIS payment code — and shows exactly how it turns into a QR matrix, down to selecting a field in the payload and watching the specific black squares carrying those bytes light up

Suara ke Kursi
Shows how 151.8 million Indonesian votes became 580 parliamentary seats, and lets anyone drag the election threshold or swap the divisor method and watch the entire parliament recompose seat by seat

Compression Lab
Shows what a piece of text actually costs to store, and how that cost changes depending on how much a compressor is allowed to remember about it — with every number, including the cost of the model itself, computed live from code written from scratch
