I added client-side Video Preview to my Safe Zone Checker (No server costs!)
Hey everyone! 👋
A few weeks ago, I shared OverlayCheck.com—a tool to check if TikTok/Reels UI blocks your content.
The #1 request I got was: "This is great for screenshots, but I need to check my actual DETAILS video files."
The Problem: Hosting user videos is expensive (bandwidth/storage) and risky (privacy/content moderation). As a bootstrapper, I didn't want a massive AWS bill just to let people preview an overlay.
The Update: Today I'm pushing a major update: Video Support that runs 100% in the browser.
I built a custom video player that interacts with the overlays in real-time.
🚫 No Server Uploads: The video file never leaves your device. It creates a local blob URL for instant preview.
🔒 Privacy First: Because it's client-side, your unreleased content stays private.
âš¡ Zero Latency: No "processing..." bars. It plays instantly.
I'd love for you to try it out with a 9:16 video and let me know if the playback feels native!
