Bilibili Comments & Replies Scraper

Extract public comments and nested replies from known Bilibili videos. Provide BVIDs or video URLs and get structured rows for social listening, creator research, brand monitoring, market research, and AI dataset preparation.

What does this Actor do?

Bilibili comment threads contain buyer opinions, fandom reactions, creator feedback, and product/community signals. This Actor turns public Bilibili comment and reply text into clean, exportable rows with stable IDs and parent-child links.

• Scrapes public top-level Bilibili video comments.
• Optionally collects bounded nested replies for each comment.
• Resolves video metadata such as BVID, AID, title, and owner name.
• Preserves parent-child relationships with rpid, rootRpid, and parentRpid.
• Supports anonymization of public commenter fields while keeping a stable hash.

Creator researchers: study comment engagement, frequent topics, and reply chains.

Market researchers: export Chinese video-platform discussion data for qualitative analysis.

AI dataset builders: collect public CJK/emoji-rich conversation text with timestamps and IDs.

FAQ

Does it scrape private or logged-in content? No. It only uses public Bilibili video/comment endpoints.

Can it discover videos by keyword? No. Use the related video search Actor first, then pass selected BVIDs here.

Why are there zero rows for a video? The video may be unavailable, comments may be disabled, or Bilibili may return no public comments for the requested sort/region.

Responsible use

This actor collects only public Bilibili video comments and replies. Do not use it for private, logged-in, paid, or restricted content. Comments can contain personal or user-generated content; use anonymizeUsers when sharing datasets or building AI/sentiment workflows.
