BiliSmooth - Bilibili Playback Helper

Switch Bilibili video CDNs and see download speed, playable buffer time, and playback status in a floating panel.

BiliSmooth helps you manage Bilibili video playback when a delivery route is slow. A small floating panel shows download speed and how much buffered video remains at your current playback speed. The extension reads the active Bilibili page's title, URL, playback information, and media addresses for these controls. Analysis and settings stay in your browser. Playback and route probes connect to Bilibili/CDN services, which receive your IP address and signed media URLs; compatibility relays also receive the original media URL. There is no developer telemetry or automatic diagnostic upload. WHAT YOU CAN DO • View playback status, download speed, and playable buffer without leaving the video. • Let BiliSmooth choose a delivery route, or select one manually. • Try another route when playback stalls, with optional automatic recovery. • Open a separate dashboard for playback controls and video selection. • Choose English or Chinese, light or dark appearance, and the floating panel's position and visible metrics. HOW TO USE Open a video on bilibili.com. Hover over the BiliSmooth tab for metrics, or click it for playback controls. Click the extension's toolbar icon to open the dashboard. If the video page was already open when you installed the extension, refresh it once. BiliSmooth does not require an account of its own. Bilibili's normal account and content requirements still apply. It preserves the selected quality and does not unlock paid quality or restricted videos. Route availability depends on your connection and the video. BiliSmooth is an independent open-source project, based on Bilibili Accelerator by realzza. It is not affiliated with or endorsed by Bilibili.
