Overseas Video Speedup for bilibili автор John_H

(If you have a Tampermonkey/Greasemonkey script with the same functionality installed, please remove it first to avoid conflicts.)

Did you pay for a bilibili Premium membership, only to spend the whole time staring at a buffering wheel — money straight down the drain?

This bugged me for a long time, until I finally found something that actually works

So I decided to turn it into a browser extension. There must be plenty of people with the same problem — I hope it helps you too!

🆓 This extension is completely FREE, and guaranteed to stay "FREE FOREVER"!
⚡ Nothing to configure, just install it and it works!

Open any bilibili video after installing and it switches you to a faster route for your region behind the scenes. Faster loading, less buffering, and even 4K plays straight through.

Celebrating the big 2.0.0 update!!

■ Key features
・Works out of the box — no setup at all, it just works once installed
・Worldwide support — expanded from Taiwan / Singapore to support every country! Use the "Custom node list" to cover any country not yet listed
・Hand-tested nodes — listed countries have their fastest nodes picked through real hands-on testing, with more countries coming soon... Use the "Custom node list" to cover any country not yet listed
・Live stream support — new in 2.0! Switch live rooms between the international and China routes and their backups; falls back to the international route automatically when the route is poor
・Greatly expanded CDN nodes — around 300 nodes across Alibaba Cloud, Tencent Cloud, Huawei Cloud, Akamai, and more
・Custom node list — add as many nodes of your own as you like, with speed test and sorting too; pair it with the official CDNSpeedTest tool (Windows) to find the smoothest nodes for you and add them automatically
・Automatic failover — detects failed requests or stalled playback and silently switches to bilibili's own backup node first; only asks you if the backup also fails
・Per-node speed test — dedicated pages for videos and live streams compare each node's / route's speed in real time, with crowns for the top 3; stop anytime, adjust the test limits, and optionally sort nodes by the results
・Auto-switch to the fastest node — optional (off by default): speed-tests in the background for each video and switches to the fastest node automatically
・Live status display — shows the CDN route actually in use in the top-left corner of the player, handy for comparing results
・Multi-language UI — automatically switches between Traditional Chinese / Simplified Chinese / English based on your browser language
・One-click disable — turns off completely, restoring the browser's original behavior; videos and live streams can also be turned off separately

■ How to use
