// Simple Blog Application (MIT License)
const KEY = 'darekdari.blog.v1';
export function loadPosts() {
try {
const raw = localStorage.getItem(KEY);
return raw ? JSON.parse(raw) : seedPosts();
} catch {
return seedPosts();
}
}
export function savePosts(posts) {
localStorage.setItem(KEY, JSON.stringify(posts));
}Built different.
On purpose.
Most tool sites are ad farms with a search bar. We built the opposite: fast utilities, real projects, and code you can actually learn from.
// no accounts · no paywalls · no dark patterns100% free, forever
Every tool, every project, every line of source code. No trials, no “premium” unlocks, no surprise invoices.
No unnecessary signup
Your browser is the backend. Open a tool, get your result, close the tab. That’s the whole flow.
Blazing fast by design
Client-side processing, zero bloat, sub-second loads. Tools that feel instant because they are.
Learn by real example
Each project teaches a genuine skill — APIs, auth, state management — with code written for humans.
