PiliPlus

PiliPlus is an unofficial third-party app for Bilibili, a major Chinese video-sharing platform. It is built with Flutter, which allows it to run on Android, iOS, Windows, and Linux from a single codebase. The app connects to Bilibili's official API to browse and play content; the README states that it does not include any unofficial decryption of protected material.

The README is primarily written in Chinese. Based on the feature list, the app covers the full range of Bilibili functionality: browsing recommended and trending videos, watching live streams, managing favorites folders, following and unfollowing users, and reading or posting comments and replies with emoji, rich text, and user mentions. It also handles the platform's social dynamics system, which works similarly to short-form posts or status updates.

Video playback includes DLNA casting to a TV or compatible device, offline caching for later viewing, hardware-accelerated decoding, adjustable subtitle and bullet-comment (danmaku) size, picture-in-picture mode, automatic skip of drama intros and endings, audio normalization on Android, and speed controls with a long-press shortcut for 2x speed. The player supports multiple video quality and audio quality options and can remember playback position. SponsorBlock integration is also included, which is a community system for skipping sponsored segments.

PiliPlus is a fork of two earlier open-source Bilibili clients (pilipala and PiliPalaX), with additional modifications. The disclaimer in the README describes the project as a personal effort for learning and testing, asks users to delete downloaded builds within 24 hours of download, and credits the community-maintained bilibili-API-collect project for the API documentation.
