There is a list of languages available to use with TT: Chinese, English, German, French, Japanese, Korean, and Russian. The developers created a support forum to answer inquiries and better understand what users wanted: new commands, features, Macro languages, etc. The most recent Tera Term Pro platform was built on the original open-source code and implemented features from the first Pro program: SSH2, etc. The first TeraTerm laid out the foundation for the Pro TT, and the Pro provided the basis for more open-source projects to emerge. Tera Term Pro provides a built-in server that has API integration with remote systems, ODBC support with the Macro Scripting Language, reoccurring commands, and SSH2 support.

Tera Term Pro is the edition that came after the original release and was not developed by the founding creator. The original and recent versions of TT are open-source and available for keen developers to modify. The software is free of malware and spyware. The emulation tool does not have in-app advertisements. If you can build with the C, C++, and Pascal programming languages, then you can modify Tera Term based on the BSD License agreement.

TT is an open-source project that began in 1994.
