I wanted to see how far I could go building a notes app using only what modern browsers already provide – no frameworks, no storage APIs, no build step.
What it does:
Single HTML file, no deps, 111 loc
Notes live in the URL hash (shareable links!)
Auto-compressed with CompressionStream
Plain-text editor (contenteditable)
History support
Page title from first # heading
Respects light/dark mode
No storage, cookies, or tracking
The entire app is the page source.
