Clipzy Media PWA - High-speed, zero-watermark HD media downloader

Hi Product Hunt! 👋 I’m Jhon, a 17-year-old developer, and I built Clipzy because I wanted to move away from generic tutorial projects and tackle real-world software engineering challenges: cloud resource optimization and advanced anti-bot evasion. While Clipzy works as a seamless, ultra-fast PWA to download HD/4K media without watermarks, the real magic happens in the backend. To host it effectively on a micro-cloud tier (Koyeb Free), I had to engineer solutions for several heavy constraints: 🛡️ TLS/JA3 Fingerprint Bypass: Platforms like YouTube or TikTok block basic scrapers with 403 Forbidden errors. I integrated curl_cffi to dynamically impersonate real browser fingerprints (Chrome 120), bypassing modern bot detection natively. 🧠 FFmpeg Concurrency Tuning: Transcoding media is highly resource-intensive. To prevent Out-Of-Memory (OOM) container crashes, I fine-tuned Gunicorn to use a single worker with a pool of 8 async threads—centralizing heavy buffers while serving multiple parallel requests. 🧹 Atomic Auto-Clean Engine: A low-impact background thread purges orphan files older than 60 minutes, keeping the ephemeral storage pristine. Clipzy is 100% Open Source and free to use. I’d love to get your feedback on the architecture, thread handling, or overall UX! Check out the repo here: https://github.com/jhon-henao13/...
