№ 02 / Story
Why it exists.
AppsGolem started as a personal tool. John kept cutting clips out of long YouTube podcasts and lectures by hand — pasting URLs into yt1s, hitting watermarks, dodging popups, then editing the result in a second tool. It was tedious, and the free cutters online were either ad-laden, malware-prone, or capped at 720p.
The first version of AppsGolem was a single page: paste a URL, set the in and out, get a clean MP4 in 4K with no watermark. Over time it grew into a freemium toolkit — cutter, TikTok downloader, Twitch VOD downloader, most-replayed extractor — still built and supported by one person.
200,000+ clips later, the pitch hasn't changed: a tool that does the job, doesn't watermark the output, and doesn't serve you malware to keep the lights on. Paying customers fund the workers and the bandwidth; the free trial exists so you can verify the workflow before paying.
Every line of code, every refund email, every new feature ships from the same place. If you have questions or feedback, that's the address it lands at too.

What's actually inside.

Encoding pipeline — yt-dlp pulls source video at the highest available stream, ffmpeg cuts to the selected range with
libx264 veryfast CRF 22and bit-perfect AAC audio copy. Optional fast mode skips re-encode entirely (~10× faster, frame-accurate to keyframe boundaries). - → 4K source pass-through — if YouTube serves 2160p for the source, the cutter outputs 2160p. No transcoding to 1080p, no quality cap on paid plans.
- → Architecture — Django on the web side, Huey workers on dedicated machines for the yt-dlp + ffmpeg pipeline, Redis for job queues and progress polling. Worker boxes are kept thin (no user data) so a worker crash never touches paying users' accounts.
- → Privacy posture — no third-party ads, no tracking pixels, no session replay. The only outbound network calls are to Stripe (payments) and your YouTube/TikTok/Twitch source. Cookies are session-only.
- → Languages — the entire UI is translated into 38 languages. Translations are reviewed by native speakers for the top 10 traffic locales; the rest are machine-translated with manual spot-checks.
