As a full-stack developer, I have a habit of building tools to scratch my own itch. Here are two I recently shipped — both free, no ads, no signup required.
Tool 1: Thumb Extract — YouTube Thumbnail Downloader
Every time I needed a YouTube thumbnail for a project or reference, I'd end up on some spammy site with 10 popups before I could download anything. So I built a clean version.
What it does:
- Paste any YouTube URL → get the thumbnail instantly
- All resolutions: HD (1280×720), SD (640×480), and default
- Also downloads channel profile pictures in full resolution
- Downloads channel banner/cover art at full size (2560×1440)
- Zero ads, zero signup, zero watermarks
- Works on videos, Shorts, live streams, and old videos
Tech approach:
The key insight was using YouTube's image CDN directly rather than scraping the page. This makes it near-instant and works for any public video.
Tool 2: Quick CPS Test — 0-Latency Click Speed Tester
Every CPS (clicks per second) test site I tried had noticeable input lag caused by event debouncing or heavy DOM manipulation. The results were inaccurate by design.
What it does:
- Measures your CPS with 0-latency click detection
- Test modes: 1s, 5s, 10s, 60s, 100 clicks
- Tracks personal best and average CPS
- Clean UI with zero ads or distractions
- Works perfectly on mobile (touch events)
Tech approach:
Used raw mousedown events instead of click events to eliminate the browser's built-in click delay. Removed all unnecessary DOM reflows during the test interval.
What I learned building these
- Simple tools get used. Both tools do one thing extremely well. No feature creep.
- Performance is a feature. Users immediately notice when something feels instant vs. sluggish.
- SEO from day one matters. Even small tools benefit from clean URLs, fast load times, and descriptive meta tags.
If you try either tool, let me know what you think — especially if you find any edge cases or bugs. Always looking to improve.
