Proxy direct links through Cloudflare's edge network for ultimate stability and speed.
FastLink is a tool I built to fix slow and unstable direct downloads. It uses Cloudflare's massive global network as a proxy, so your downloads go through their edge nodes instead of directly from the slow source.
It also grabs detailed metadata from video and audio files instantly, right in the browser, without needing to download the whole file first.
| Feature | How it works |
|---|---|
| Global Acceleration | Routes traffic through Cloudflare Edge to bypass throttling and strict network limits. |
| Resume Support | Keeps Byte-Range headers intact. Pausing and resuming your downloads actually works. |
| Deep Media Analysis | Runs mediainfo.js via WebAssembly to grab things like Bitrate, Codec, and Resolution on the fly. |
| Edge Security | Comes with SSRF mitigation, TLS fingerprinting, and dynamic browser emulation so links don't get blocked. |

# 2. Drop it into FastLink
-> The UI validates it instantly on the client side
# 3. Get your results
-> A proxied, high-speed download link
-> Extracted Codec & Container dataBuilt on top of some awesome open-source projects.
