IntelliJ IDEA

Still the deepest understanding of a codebase in any editor.

What it is sold for

Serious Java and Kotlin development.

Same shelf

The rest of editors and ides, alphabetically. Sharing a category is a filing decision, not a relationship.

• Fleet
  JetBrains' distributed editor, using the IntelliJ engine but separating the interface from where the code is processed.
• GoCodeo
  An agent inside the editor that builds, questions and tests, sold on producing code that is ready rather than illustrative.
• Kite
  An early completion product that shut down and open-sourced its work. The domain is listed for sale.
• MarsCode
  ByteDance's cloud IDE with a built-in assistant, supporting a wide language range.
• Neovim
  A Vim fork with an embedded Lua runtime and a language server protocol client, which made the modern plugin ecosystem possible.
• OneCompiler
  An online IDE covering seventy languages, useful when the environment matters less than running the snippet.
• Sublime Text
  A fast native editor, still commercial, whose speed and multiple cursors set expectations everything since has had to meet.
• VSCode
  The editor that took the market. Free, extensible, and now shipping agent workflows in the box.
