Designed, written, and operated solo · dnschkr.com
A domain intelligence platform that analyzes more than 240 million domains a day. I own
every layer: ingestion, the Elasticsearch index, the API, the front end, and the servers it
runs on. Nobody else has ever had a commit in it, which is either a good sign or a warning,
depending on your view of bus factor. Most people meet it through the free DNS Checker, which pulls every record type for a domain in one pass, then the DNS propagation checker to watch a change land on resolvers around the world, and the email authentication tools for SPF, DKIM, and DMARC. Most of my Linux, DNS, and networking articles come from keeping it up.
700+ articles, single author
Field notes on shipping real systems, written from work that went to production rather than from tutorials. The bulk is WordPress, Linux, DevOps, and application security, roughly 130 pieces each, then databases, JavaScript, CSS, AI engineering, and regex. The most-read articles and the topic map are on the writing page. Start with the Tor bridges setup guide or the yt-dlp cheat sheet, which is where most readers start.
Birth charts and horoscopes, calculated in both zodiacs
Kendraya is a free birth chart calculator that works from the sky rather than from a table of dates: a birth date, time, and place give the rising sign, Moon sign, and houses, and the same positions drawn as a Vedic astrology chart with the nakshatra and dated Vimshottari dasha periods. Western and Vedic views sit side by side and are never mixed, the positions are labelled as calculation and the readings as tradition, and nothing needs an account.
The pages built to come back to are the daily horoscope for all twelve signs, worked out from the day's real planetary positions, with a page per sign such as Leo horoscope today and Libra horoscope today that also carries the week and the month. The reference pages answer one question each: is Mercury in retrograde right now, with the Mercury retrograde 2026 dates and every other planet's stations, and the zodiac signs dates for the year in both zodiacs. The baby name finder lists girl, boy, and gender-neutral names with meanings and origins, and can narrow them by the naming sound of a birth date and time.
Privacy-first comment system
Threaded comments, reactions, and star ratings you embed with one script tag, funded by subscriptions instead of by watching the people reading your site. AI moderation, a REST API, and TypeScript SDKs. The embed and API documentation covers the one-script install and the webhooks, and the plans are what funds it instead of ad tracking.
14,333 licensed providers, Texas first
Daycare Index is a childcare directory covering 14,333 licensed providers across Texas. Parents search by city or ZIP, then compare programs and ages, hours, locations, and licensing and inspection information side by side. Listings are ordered on the record alone: nobody can buy a better position, and there is no sponsored tier. The heaviest catchments are daycare in Houston and Dallas, and the guides answer the two questions parents actually open with: how to choose a daycare and what daycare costs in Texas.
Height comparison tool, 550 real and fictional subjects at true scale
The quickest answer to "what's taller?" I could build. Whats Taller drops Godzilla next to the Eiffel Tower, the Statue of Liberty next to Burj Khalifa, or your own height next to a T. rex, and the scene renders every subject at true relative scale. Each measurement carries its source, fictional heights say which version they come from, and any comparison can be shared as a link or downloaded as an image. Free, no account, and nothing you enter leaves your browser.
The ready-made scenes are the quickest way in: the world's tallest buildings side by side, or Godzilla against the rockets. Every subject also has its own height page, including each Godzilla incarnation, and how to compare heights explains the scaling underneath. Anyone who just wants to settle what is taller between two particular things can start from the home page and pick both subjects themselves.
51 states and DC, 8 practice areas
An independent attorney directory built on state bar records rather than paid placement. No firm owns it and nobody can buy a better position in the listings. Coverage runs deepest in Texas and California, and firms wanting their own record corrected go through the attorney page.
228 US car seats, 15 brands, compared on the manual
A baby car seat catalog built from manufacturer manuals rather than from marketing copy: 228 US models across 15 brands, each one carrying the weight, height, and age limits its own manual publishes, with the source cited and unknown values left blank instead of guessed. Parents come in by stage, so the shelves are infant car seats, convertible car seats, and booster seats, and the comparison tool puts up to four of them side by side. There is no hands-on or crash testing behind it and the site says so on every page.
The two pages people actually arrive on are the reference ones: US car seat laws by state, which keeps every state's rear-facing, forward-facing, and booster thresholds on one page with the statute and the date each was checked, and the NHTSA car seat recall list, 71 recalls since 2010, refreshed daily, with the hazard and the remedy for each. The stages guide is the starting point for anyone who does not yet know which type they are shopping for.
10,225+ Sinhala songs, 3,390 artists · lyrics-lk.com
Lyrics LK is the largest Sinhala lyrics archive on the web: 10,225 songs by 3,390 artists as of 13 September 2026, every one in Sinhala script and in Singlish, indexed by song, artist, and lyricist. Sri Lankan music was badly served online, so I built the archive I wanted to exist: searchable, checked against the recordings, corrected in the open, and with no popups between you and the words. It now answers more than 650,000 Sinhala lyric searches a month.
The songs people are searching for most this month are Chamara Weerasinghe's Mathakayan Obe lyrics, H.R. Jothipala's Hanga Gal Lene lyrics, Nimesh Chamika's Mandaram Handawe lyrics, Bachi Susan's Bambara Nade lyrics, and Pradeep Rangana's Pem Sihine lyrics, which between them draw more than 110,000 searches a quarter.
1,700+ Sinhala songs with guitar chords · chordslk.com
Chords LK is the largest collection of Sinhala guitar chords online: more than 1,700 songs with chords and tabs as of 13 September 2026, with a built-in transposer so any song plays in your key. The companion to the lyrics archive, for the people actually trying to play the songs rather than just read along.
The most-played pages right now are Jayasri's Sheela chords, Sanuka Wickramasinghe's Saragaye chords, Bathiya and Santhush's Mal Pan Podak chords, and Priya Sooriyasena's Atha Ran Viman chords.
521 Jurassic World Alive creatures, exported from the game itself
A Jurassic World Alive database where the numbers come out of the game rather than off a wiki edit. The whole catalog, 521 creatures, 2,005 ability records, and 250 fusion recipes, is exported from the game's own static database and its live server data, so every patch regenerates the site instead of being typed in by hand. The dinosaur guide is the front door: filter by rarity, class, or hybrid type, then open any creature for its stats, moves, resistances, and level costs.
The pages built for players mid-battle are the hybrids and fusion recipes, the ability reference that the usual fan sites skip entirely, the stat comparison tool, and raid strategies. Tournament leaderboards cover the competitive side.
19 varieties, caffeine data, and a joke
Half the fun of this one is the joke and the other half is real. It catalogues every Dr Pepper variety with the caffeine and nutrition numbers, and takes the caffeine-dependence part more seriously than the name suggests. The pages doing the real work are the per-variety breakdowns like Dr Pepper Zero, the am I addicted to Dr Pepper self-check, and the recipes. It is also the test bed for the structured data and search work I later apply to the bigger sites.
Three DNS games and a twelve-mission learning path
DNS taught by making you run one. DNS Rush is a resolver strategy game: a finite cache, finite lookup capacity, and a queue of queries that has to keep moving, across twelve campaign levels plus daily and endless modes with a server-verified leaderboard. It's Always DNS hands you a broken site, a limited investigation budget, and twelve authored incidents to diagnose and repair, and Packet Quest walks a query through referrals, aliases, and expired answers as a maze.
Underneath the games is a twelve-mission DNS learning path that teaches how DNS works through experiments and explanation checks, with teaching notes and protocol references for anyone using it in a classroom. Progress records stay in the learner's browser and are self-reported, not a verified qualification. It is the teaching half of what DNS Checker does in production.
Code paste for WordPress developers
A paste bin that knows what it is looking at. PHP and JavaScript syntax highlighting, and every WordPress function and hook in your snippet auto-linked to its documentation. Behind that sits a full core reference, so the pages developers land on are the ones they were already searching for: the init hook, get_posts(), WP_Query, register_post_type(), add_filter(), wp_enqueue_scripts, and save_post.
Single-purpose encoder
Paste text in, get Base64 out. Nothing else on the page, no account, and no step between
arriving and having the answer. The encoder is the whole product; the guides cover doing it in code instead, in PHP and in Python.
Single-purpose decoder
The other direction, on its own domain rather than as a tab on the encoder, because that is
how people actually search for it. Same shape: a decoder, a decoding guide, and the explainer on Base64 padding that most "invalid string" complaints turn out to be.
