Summary

JetBrains updated its built-in IDE terminal starting with version 2026.3 to run on libghostty, replacing JediTerm. The new engine adds support for modern terminal protocols used by AI coding agents, matches IDE themes, and renders rich output properly.

What changed

  • Switched the built-in IDE terminal engine from JediTerm to libghostty starting with 2026.3.
  • Added support for the Kitty keyboard protocol and xterm's modifyOtherKeys to handle multi-line prompts correctly.
  • Added automatic theme switching based on the current IDE dark or light mode.
  • Added support for nearly 50 control sequences to properly render output from AI agents and system tools.

Availability

Rolling out

“The libghostty -based engine is already on by default in the reworked terminal in the 2026.3 EAP builds of your IDEs, and it will stay that way through the Beta and Release Candidate builds and in the stable release.”

Founder takeaway

If you use JetBrains IDEs with AI coding agents in the terminal, check your 2026.3 builds to benefit from the new libghostty integration and report any rendering issues.
