There are a some amazing tools that can run in a browser. This page is a collection of some of those tools.
An amazing Font Creater. Font tools have been pricey for years. I've been really excited to watch the progress of this site since I stumbled upon it. It's beautiful. Have fun!
Real time lightning strikes. This is fun to monitor in a storm.
One of my favorite tools. No login required, and accessable from anywhere. Unfortuinately, this site is shutting down at the end of the month.
This is pretty amazing. "Airtable is a modern database created for everyone," "As simple as a spreadsheet."
A photo editor.
Similar to Airtable. Still in Beta and not quite as feature rich.
A processing editor. Easily collaborate on a sketch with a shared link.
Virtual Electronics Labs by Autodesk.
Collaberative music mixing.
"Be Prolific. DistroKid is the easiest way for musicians to get music into iTunes, Spotify, Amazon, Google Play, and more. Upload as much as you want, keep 100% of your royalties."
Seems to be a great service for musicians, Not exactly a web tool in the same way as these other sites, but I feel it is a valuable resource.
Another in-browser font creation studio.
Public e-mail addresses. I really dig this tool; send from and check any mail box. No login required. I would advice not to use this service for anything that might be security sensitive.
Yet another font creation tool. Yes, I really dig typography. Metaflop is based on Metafont. Instead of creating editing each glyph individually, Metaflop allows the user to adjust a series of parameters that adjust characteristics across all characters in the font.
Mozilla's in-browser front-end code editor. Instant preview!
My go-to site for when I need to generate QR Codes.
A color scheme creation and sharing tool.
A color picker! I started using this because my choice html editor didn't have a native color picker.
"The fastest way to swap cryptocurrencies." No account needed.
