Discover MediaGo, a free open-source tool that sniffs web videos without packet capture. Download B站 and m3u8 streams effortlessly across Windows, macOS, Linux, and Docker.
No packet capture needed — one-click sniffing of web video resources, efficient downloads at your fingertips.
Have you ever wanted to save your favorite online videos but had no idea where to start? Or been put off by the technical complexity of packet capture? Today, I'm recommending an open-source and free cross-platform video extraction tool — MediaGo — that makes video downloading simple and efficient!
I've been using it for a while now, and it truly meets many of my needs: downloading B站 (Bilibili) educational videos for offline viewing, saving precious live stream replays, and grabbing streaming content I need temporarily. The best part? It requires no technical background — just a few simple clicks and you're done.
🔍 What is MediaGo?
MediaGo is a powerful and efficient cross-platform video extraction tool that supports streaming media downloads, m3u8 video downloads, and B站 video downloads. With MediaGo, users can easily download and manage various video resources, enjoying a seamless mobile playback experience.
Although it shares its name with a multimedia management software developed by Sony years ago, this tool — open-sourced on GitHub by Chinese developer caorushizi — focuses more specifically on video extraction and downloading, making it far more practical.
✨ Key Features of MediaGo
✅ No Packet Capture Required
MediaGo comes with a built-in browser that can easily sniff video resources from web pages. Simply select the resources you want to download from the detected list — quick and straightforward. This means you don't need to open browser developer tools or hunt for m3u8 links; everything is automated.
📱 Mobile Playback
Easily switch between PC and mobile devices for seamless viewing. Once downloaded, you can watch the videos on your phone right away. I've tested this, and the downloaded videos are typically in MP4 format with excellent compatibility, playing smoothly across various devices.
⚡️ Batch Downloads
Supports simultaneous downloads of multiple videos and live stream resources, making full use of high-speed bandwidth. This is especially handy for users who need to download entire course series or multi-episode videos.
🐳 Docker Deployment
In addition to the desktop client, MediaGo also supports Docker deployment of a Web version, ideal for enterprises and developers, with simple and quick installation and configuration. This allows you to deploy it on a NAS or server and access it remotely anytime.
🎯 Multi-Format & Multi-Platform Support
MediaGo supports downloads in multiple video formats, including m3u8 and mp4, with particularly strong support for B站 videos and m3u8 streams. It runs on Windows, macOS, and Linux, so you can use it on a wide range of devices.

Batch Download Tips
MediaGo supports adding multiple download tasks at once. You can open several video pages for the software to sniff, or manually add multiple video links. The software will download them in parallel, fully utilizing your network bandwidth.
🐳 MediaGo Docker Deployment (Advanced Usage)
For users familiar with Docker, MediaGo offers a convenient Docker deployment method, allowing you to run a Web version on your NAS or server for remote access.
Basic Docker Deployment Command
docker run -d --name mediago -p 8899:8899 -v /your/mediago/data:/root/mediago registry.cn-beijing.aliyuncs.com/caorushizi/mediago:latestUsing Docker Compose (Recommended)
Create a docker-compose.yml file with the following content:
services:
mediago:
image: registry.cn-beijing.aliyuncs.com/caorushizi/mediago:latest
container_name: mediago
restart: unless-stopped
network_mode: bridge
ports:
- "8899:8899"
volumes:
- /your/mediago/data:/root/mediagoThen run:
docker-compose up -dOnce deployed, access the Web version of MediaGo by visiting http://your-server-IP:8899 in your browser.
Note that the Web version offers fewer features than the desktop client — it only supports manual downloads and has no account protection. If you expose it to the public internet, be sure to implement proper security measures.
🔄 MediaGo Remote Access via Intranet Penetration
If you've deployed MediaGo on a home NAS or intranet server, you may want to access it from outside. This can be achieved using intranet penetration tools.
cpolar is a simple and easy-to-use intranet penetration tool that supports Linux and can be installed on NAS systems like Feiniu Cloud and Synology. Basic steps:
- Install cpolar on your NAS
- Create an HTTP tunnel specifying local port 8899
- Obtain a public access address
- Use that address to remotely access your MediaGo service
This way, you can access your deployed MediaGo service from anywhere via the internet, downloading and managing videos remotely.
