Bilibili Danmaku Scraper: Full Bullet Comments (No Login)

Download the complete danmaku (弹幕, bullet comments) of any Bilibili video, without an account: every comment that flies across the video, with the exact second it appears, its text, color, position mode, send time and the sender's hash. All parts of multi-part videos, every segment of long videos.

• Complete, not a sample. Bilibili's old XML danmaku file is capped (often 1,000–3,000). This Actor reads the segmented danmaku feed the player itself uses, six minutes at a time, so long videos come back in full.
• Any video link: bilibili.com/video/..., b23.tv short links, BV or av ids. Add ?p=2 to take one part only.
• Analysis-ready: sorted by video time, with ISO timestamps, ready for sentiment, keyword or "hot moment" analysis.
• No login, no cookies, no API key.

Tested on the platform: 3 videos → 4,249 danmaku in 11 seconds, every request succeeding.

Input

{ "mode": "danmaku", "videoUrls": ["https://www.bilibili.com/video/BV1xx411c7XX", "https://b23.tv/AbCdEf1"], "maxDanmakuPerVideo": 20000 }

maxDanmakuPerVideo (default 5,000) caps each video, counted in video-time order. The same Actor can also search videos, fetch video details and creators (mode: search, videos, creators): see the Bilibili Scraper.

FAQ and limits

• Is it every danmaku ever sent? It is everything Bilibili currently serves for the video. Bilibili's danmaku counter on the video page also counts deleted or expired ones, so it can be higher than what any viewer sees.
• Comments (评论)? Not included: Bilibili shows only 3 comments per video to logged-out visitors.
• Account needed? No.
