These are online tools that I’ve been using for long enough to recommend.

Markdown
- stackedit - An almost perfect online markdown editor.
Regex & Text Manipulation

Online Compilers / Pens

- FilePizza - This is a clever little file send that uses WebRTC to send files peer-to-peer. Files are encrypted and you can password protect them. The file is gone after you close the tab.
Meme Creation
- ImgFlip - The best online meme generator I’ve found. Tons of templates, easy to use interface, and you can create an account to save your memes.
Shopping
- CamelCamelCamel - The best Amazon price tracker I’ve found. It shows price history charts and can alert you when prices drop.
Music
- Tune Find - The best site for finding music from your favorite TV shows and movies. Just enter the show or movie name and it will show you all the songs used in it.
