I Built a TikTok Downloader with Go — Here's What I Learned

ClipTool is a free TikTok downloader built in Go that removes watermarks and focuses on speed, simplicity, and clean output.

The backend uses Go concurrency, PostgreSQL, ClickHouse, and S3-compatible storage to process and delete videos quickly.

The frontend is built with React and Vite, with SSR and Nginx-based bot detection to serve SEO-friendly pages to crawlers like Googlebot and Bingbot.

The design avoids user tracking and supports multiple formats and devices, making the downloader more privacy-friendly and usable.
