TL;DR — NudiTok is a free, browser-native short-video platform for adults 18+. It runs as a Progressive Web App on any modern browser, ranks videos via engagement-weighted scoring, and gives creators a profile page with follows, likes, comments, shares, and saves.
NudiTok is a NSFW short-video platform launched as a TikTok-style vertical swipe feed for adults 18+. As of April 2026 the catalogue holds thousands of 15-to-60-second clips from creators worldwide, playable in any modern browser without an app install or paywall.
NudiTok is a TikTok-style platform purpose-built for 18+ content. The feed works the same way — swipe up for the next video, tap to pause, double-tap to like — but the catalogue is adult-only and videos are served with HLS adaptive streaming tuned for mobile networks.
Every video on NudiTok plays in full at no cost, with no credits, tiers, or time-limited previews. The platform is ad-supported for sustaining bandwidth; creators keep ownership of their uploads and can remove them at any time.
No — browsing and playback are fully open without signing in. A Google account unlocks likes, comments, follows, saves, and a personalised For You feed, but the public feed, hashtag pages, and creator profiles all render the same for signed-out visitors.
Each video carries a precomputed feed_score that combines like, comment, share, and save counts weighted 3, 5, 8, 10 respectively, times an admin-tunable boost multiplier, times 0.7; the remaining 0.3 is a per-video randomiser. Signed-in users' feeds additionally filter videos they've already watched or marked "not interested".
Uploads are transcoded through an FFmpeg pipeline and stored on S3-compatible object storage behind a CDN. Playback uses HLS adaptive bitrate streaming on networks where it's available and falls back to progressive MP4 on networks or browsers where it isn't.
