Free Browser Tools — LK Forge
LK Forge builds in-browser tools that each do one job well — word and text tools, a developer suite (JSON, Base64, JWT, text diff, regex, a REST API tester), network tools, converters, generators, everyday calculators, a world clock and timer, plus live-data tools for weather, space, and Earth (earthquakes, volcanoes and wildfires). Every tool runs in your browser with no sign-up and no download, and they are all free — VoiceFlow adds an optional one-time Pro unlock for heavier use.

Invoice Generator
A free invoice generator that runs entirely in your browser. Add your business details and logo, list each product or service with a quantity and unit price, and set a discount and tax — the subtotal and total update as you type. Pick from 14 currencies, then download a clean PDF invoice or print it. Need many invoices at once? The Bulk Invoice Generator creates them from an Excel file and downloads a ZIP of PDFs. No sign-up, no watermark, and nothing is uploaded.
/tools/documents/invoice-generator/ Receipt Generator
A free receipt generator that runs entirely in your browser. Record who paid, list what was paid for with a quantity and unit price, set the tax and the payment method, and enter the amount paid — the total and any balance due update as you type, and the receipt is marked PAID when nothing is left to pay. Pick from 14 currencies, then download a clean PDF receipt or print it. No sign-up, no watermark, and nothing is uploaded.

Earthquake Tracker
A live map and list of recent earthquakes worldwide and near you, straight from the USGS feeds — filter by magnitude and time, see depth, place and time, and tap "Near me" to sort by distance with your location kept in your browser. Plus a magnitude-scale reference (Richter vs moment magnitude) and plain-English explainers on how earthquakes, seismic waves, subduction and aftershocks work. Not an early-warning system. Free, no sign-up, no API key.
/tools/earthquakes/ Volcano Tracker
An interactive world map and list of the planet's Holocene volcanoes, from the Smithsonian Global Volcanism Program — each one coloured by how recently it last erupted, from active since 2000 down to no confirmed Holocene eruption. Filter by activity or type (stratovolcano, shield, caldera and more), tap "Near me" or search a place to sort by distance with your location kept in your browser, and open any volcano's official GVP page for its full eruptive history. A catalogue, not an eruption-warning system. Free, no sign-up, no API key.
/tools/volcanoes/ Wildfire Tracker
A live map and list of active fire detections near you, from NASA FIRMS satellite thermal data (VIIRS) — each hotspot coloured by fire radiative power, its heat intensity in megawatts. Tap "Near me", search a place or pick a fire-prone region to fetch detections in a box around it, sorted by distance with your location kept in your browser; filter by the past 24 hours to 3 days or by confidence, and open any detection on Google Maps. A hotspot is a heat signature, not a confirmed wildfire, and this is not an alert system. Free, no sign-up.

VoiceFlow
Free in-browser voice dictation with automatic punctuation — press the mic, speak naturally, and your words become text you can copy. Free up to 2,000 words a day; an optional one-time $8.99 Pro unlocks unlimited dictation plus save & sync. Desktop app coming soon.
/tools/voiceflow/ Screen Test Tools
Full-screen display test tools that run in your browser. Fill the whole screen with pure white as a lightbox or fill light, switch between solid colours to check a monitor, or run a dead pixel test that cycles red, green, blue, white and black so stuck and dead pixels stand out. Works on any monitor, laptop, phone or TV. Free, instant, no sign-up.
/tools/screens/ World Clock
See your live local time with an animated seconds ring and minute progress bar, plus your timezone name, UTC offset and copyable IANA ID. Toggle 12/24-hour format and switch dark or light mode — all in your browser, no sign-up.
/tools/worldclock/ Timer & Stopwatch
A countdown timer, stopwatch with laps and countdown to any date — all on one page. Stays accurate even in background tabs, with an alarm sound, quick presets (including Pomodoro), fullscreen mode and a shareable countdown link. Free, no sign-up.
/tools/timer/ Spin the Wheel
The wheel of choice: add names or options, spin the wheel and get a fair random winner — with ticks, confetti and a provably fair cryptographic pick. Paste whole lists, remove winners for no-repeat draws, share your wheel by link, or use the yes/no preset. Free, no sign-up.
