Safety First: Clean code or trusted origins only. No shady downloads.
Minimal Design: No clutter, no pop-ups, no fluff. Just the function, plain and simple.

Frequently Asked Questions

1. What makes a tool “under 50KB”?
It’s all about minimalism. A tool under 50KB has a total file size smaller than 50 kilobytes—smaller than most profile pictures. Whether it’s a browser extension, a script, or a standalone utility, it’s built lean to load fast and do its job without hogging resources.

2. Are these tools safe to use?
Generally, yes—especially if they’re from reputable sources like GitHub or Chrome Web Store. But as with anything on the internet, don’t just click blindly. Check the reviews, skim the source code (if open-source), and avoid sketchy sites promising magical results with mysterious downloads.

3. Can lightweight tools replace full-featured apps?
In many cases, absolutely. Think of them as laser-focused tools for specific tasks. You don’t need a Swiss Army knife to open a letter—a simple blade does the trick faster. Lightweight tools are perfect for streamlining one task instead of wading through bloated apps with features you’ll never use.

4. Where can I find more micro tools?
Treasure hunts aren’t just for pirates. Explore:

GitHub: Search keywords like “tiny tool” or “micro app.”
Product Hunt: Check the “Tiny Tools” collections.
Reddit: Subreddits like r/productivity, r/webdev, and r/software often feature minimalist gems shared by the community.

5. Do tiny tools work offline?
Many of them do! Bookmarklets, local scripts, and simple desktop apps are designed to run without an internet connection. Ideal for those Wi-Fi dead zones or distraction-free productivity sprints.

6. Are there risks with bookmarklets?
Only if you pick them up from shady corners of the web. Bookmarklets are just bits of JavaScript saved as bookmarks—but if maliciously crafted, they can be dangerous. Stick to open-source versions or build your own using trusted snippets. When in doubt, inspect the code.

7. Can I use these on mobile?
Some you can, especially browser-based ones or bookmarklets on mobile-friendly browsers. But mobile doesn’t play as nicely with scripts and extensions as desktop does. For now, the full magic of micro tools still lives on your laptop or PC.

8. How do I check the size of a tool?

Desktop tools: Right-click the file > Properties to view size.
Browser extensions: Use Chrome DevTools > Network tab to check asset sizes when loading.
GitHub projects: Look at the repo’s README or download size—many devs will list it clearly.
It’s detective work, but worth it if you’re aiming for a clutter-free workflow.

9. Can I create my own tiny tool?
Yes! If you know a little JavaScript, Bash, or Python, you’re halfway there. Bundle your script with tools like Rollup or Terser, trim the fat, and voila—a micro tool tailored just for your workflow. It’s like digital origami: small, efficient, and oddly satisfying.
