Universal SDK for building cross‑platform chatbots in minutes
Wechaty lets developers write a chatbot once in JavaScript, Python, Go or Java and run it on WhatsApp, WeChat, and other messengers, with Docker, Linux, Windows, macOS support.
Wechaty is an RPA SDK that lets developers create conversational bots with as few as six lines of code. By providing a unified API, it abstracts the differences between messaging platforms such as WhatsApp, WeChat, and others, so the same source runs everywhere.
Targeted at JavaScript, Python, Go, and Java developers, the SDK runs on Linux, Windows, macOS, or inside Docker containers. After installing the package (Node ≥ 16) you can write a bot, set the desired puppet protocol via WECHATY_PUPPET, and launch it with wechaty.start(). The community supplies free tokens for the web‑based puppet and additional providers for Windows or custom protocols.
Bots can be started directly with Node, packaged with npm, or executed in a Docker image (wechaty/wechaty). The Docker workflow supports both JavaScript and TypeScript without a separate compile step, making scaling and CI/CD straightforward.
When teams consider Wechaty, these hosted platforms usually appear on the same shortlist.
