TDengine provides a rich set of application development interfaces. To help users quickly develop their applications, TDengine supports connectors for multiple programming languages. Official connectors include those for C/C++, Java, Python, Go, Node.js, C#, and Rust. These connectors support both native interfaces (taosc) and WebSocket interfaces to connect to the TDengine cluster. Community developers have also contributed several unofficial connectors, such as ADO.NET, Lua, and PHP connectors.
Supported Platforms
Currently, TDengine's native interface connectors support the following platforms: X64/ARM64 hardware and Linux/Win64 development environments. The compatibility matrix is as follows:
| CPU | OS | Java | Python | Go | Node.js | C# | Rust | C/C++ |
|---|---|---|---|---|---|---|---|---|
| X86 64bit | Linux | ● | ● | ● | ● | ● | ● | ● |
| X86 64bit | Win64 | ● | ● | ● | ● | ● | ● | ● |
| X86 64bit | macOS | ● | ● | ● | ○ | ○ | ● | ● |
| ARM64 | Linux | ● | ● | ● | ● | ○ | ○ | ● |
| ARM64 | macOS | ● | ● | ● | ○ | ○ | ● | ● |
Here, ● indicates official testing and verification, ○ indicates unofficial testing and verification, and -- means untested.
Using the REST connection, which does not depend on client drivers, enables support for a broader range of operating systems.
Version Support
TDengine updates often introduce new features. The connector versions listed correspond to the optimal versions for each TDengine release.

:::warning For TDengine version 2.0 and above, it is recommended that each thread in the application establish its own connection or use a connection pool based on threads to avoid interference between thread states caused by the "USE statement." However, query and write operations on connections are thread-safe. :::

Installing Client Drivers
:::info Client drivers are only required when using native interface connectors on systems without TDengine server software installed. :::
Installation Steps
Installation Verification
After completing the installation and configuration, and ensuring the TDengine service is running properly, you can log in using the TDengine CLI tool.
