Editors and IDEs

All 10

Alphabetical. Checked on 2026-09-04; anything that did not answer says so.

• Fleet
  JetBrains' distributed editor, using the IntelliJ engine but separating the interface from where the code is processed.
  JetBrains' answer to the editor being somewhere else.
• GoCodeo
  An agent inside the editor that builds, questions and tests, sold on producing code that is ready rather than illustrative.
  Insists on the test step.
• IntelliJ IDEA
  JetBrains' Java and Kotlin IDE. Its static analysis and refactoring engine set the standard the rest of the field measures against.
  Still the deepest understanding of a codebase in any editor.
• Kite
  An early completion product that shut down and open-sourced its work. The domain is listed for sale.
  Gone: the domain is for sale.
• MarsCode
  ByteDance's cloud IDE with a built-in assistant, supporting a wide language range.
  A reminder that this market is not only Western.
• Neovim
  A Vim fork with an embedded Lua runtime and a language server protocol client, which made the modern plugin ecosystem possible.
  Rebuilt Vim's foundations without breaking Vim.
• OneCompiler
  An online IDE covering seventy languages, useful when the environment matters less than running the snippet.
  For the language you need once.
• Sublime Text
  A fast native editor, still commercial, whose speed and multiple cursors set expectations everything since has had to meet.
  Still the benchmark for how fast an editor can feel.
• VSCode
  The editor that took the market. Free, extensible, and now shipping agent workflows in the box.
  Won on extensions, then kept winning.
• WebStorm
  JetBrains' JavaScript and TypeScript IDE, with the deepest static understanding available for those languages.
  Knows your JavaScript better than your JavaScript does.
