Douyin TikTok Download API is an open-source, high-performance asynchronous tool for scraping and downloading content from four major Chinese and international social media platforms: Douyin (抖音), TikTok, Kuaishou (快手), and Bilibili (哔哩哔哩). Created by developer Evil0ctal, the project has earned over 5,100 GitHub stars and serves as a goto solution for researchers, content creators, and developers who need programmatic access to short-form video platform data.
Unlike browser extensions or simple downloader scripts, this project provides a complete REST API backend with a web-based user interface, making it suitable for both automated pipelines and interactive use. It handles the increasingly sophisticated anti-crawling measures employed by these platforms, including the X-Bogus and A_Bogus signature algorithms that Douyin and TikTok use to protect their APIs.

At its core, this project is a data scraping middleware that translates complex, platform-specific API interactions into clean, developer-friendly REST endpoints. Instead of reverse-engineering each platform’s internal API, you simply send HTTP requests to the tool’s server, which handles authentication, signature generation, rate limiting, and response parsing.
The tool is particularly valuable because short-form video platforms do not offer official APIs for bulk data access. Researchers studying viral content trends, content creators managing cross-platform publishing, and developers building analytics dashboards all rely on tools like this to access the data they need.
Which Platforms Are Supported?
The project provides dedicated endpoints for each platform, with varying levels of feature coverage:
| Feature | Douyin | TikTok | Kuaishou | Bilibili |
|---|---|---|---|---|
| Video data & download | Yes | Yes | Yes | Yes |
| Photo album (no watermark) | Yes | No | Yes | No |
| User profile & posts | Yes | Yes | Yes | Yes |
| User likes & collections | Yes | Yes | No | Yes |
| Comments | Yes | Yes | No | Yes |
| Live stream data | Yes | No | Yes | Yes |
| Following / followers | No | Yes | No | No |
| Danmaku (弹幕) | No | No | No | Yes |
This broad platform support makes the tool suitable for cross-platform content analysis and migration workflows.
Can I Download Videos Without Watermarks?
Yes, watermark-free video and photo album downloads are a primary feature. The tool achieves this by intercepting the platform’s internal video delivery URLs that serve the original high-quality content before the watermark overlay is applied.
For Douyin, both single video and photo album downloads are supported without watermarks. The API returns direct media URLs that can be passed to any download tool. For TikTok, single videos are supported. The tool also supports an iOS Shortcut integration for in-app watermark-free downloads on iPhone devices.
What Tech Stack Does It Use?
The project is built on a modern Python async stack:
| Component | Technology | Role |
|---|---|---|
| Web Framework | FastAPI | REST API server with automatic OpenAPI docs |
| Web UI | PyWebIO | Browser-based interactive interface |
| HTTP Client | HTTPX | Async HTTP requests with connection pooling |
| Anti-crawler | X-Bogus, A_Bogus | Reverse-engineered signature algorithms |
| Serialization | Pydantic | Request/response validation |
| Containerization | Docker | Easy deployment with prebuilt images |
The X-Bogus and A_Bogus algorithms deserve special mention. These are the signature generation mechanisms that Douyin and TikTok use to verify that API requests come from legitimate clients. The fact that this open-source project reverse-engineers and maintains them is a significant technical achievement, as these algorithms are updated periodically by the platforms.
How Do I Deploy It?
Deployment is straightforward with Docker:
docker pull evil0ctal/douyin_tiktok_download_api:latest
docker run -d -p 8080:8080 evil0ctal/douyin_tiktok_download_api
The API documentation is automatically generated at http://localhost:8080/docs (Swagger UI) or http://localhost:8080/redoc (ReDoc). A demo site is available at douyin.wtf with API docs at douyin.wtf/docs, though the demo has downloads disabled for policy compliance.
You can also install via pip:
pip install douyin-tiktok-scraper
Note that you will need valid Douyin cookies from your browser to use the API, as the platforms’ anti-bot protections require authenticated sessions for most endpoints.
