Cursor
App Terminal
AI code editor with integrated terminal. Based on VS Code, uses xterm.js for terminal emulation.
Cursor is an AI-focused code editor created by Anysphere, a San Francisco startup founded in 2022 by MIT graduates. Built as a fork of VS Code, Cursor adds AI pair programming features — chat, command generation, multi-file edits, and code completion powered by large language models. It became one of the fastest-growing developer tools in 2024, attracting significant venture funding and crossing 100,000 paying users.
Since Cursor's terminal is powered by xterm.js (the same engine as VS Code), its terminal capabilities are identical — good basic support with truecolor, mouse tracking, and Unicode, but lacking some modern protocols like kitty keyboard and graphics protocols. Cursor inherits VS Code's OSC 633 shell integration protocol for command decorations and navigation.
The terminal is a secondary interface in Cursor; its focus is squarely on the editor and AI experience. For terminal feature support, Cursor tracks upstream xterm.js releases — improvements there benefit Cursor automatically.
