The text editor that's all tentacles.

A pure core. Everything else is a plugin.

OctoEdit starts as a small, fast core that does one thing well: edit text. Syntax colouring, themes, side panels, custom commands and shortcuts are all added on demand — so you run only the tentacles you need.

• ⚡

  Instant startup

  A small, focused core that opens in a blink and stays out of your way.

• 🧩

  Plugin-powered

  Almost every feature is a plugin you can add, replace or remove.

• 🔧

  Made to extend

  A documented plugin SDK and Python scripting let anyone build and share new features.

• 🔀

  Cross-platform

  The same editor, with the same experience, on Windows and macOS.

• 🎨

  Themeable

  Custom syntax colouring and themes for every language and panel.

• 🌍

  Speaks your language

  The interface ships in 15 languages, the documentation in 14.

Start light. Add only what you need.

Open a clean, quick core, then switch on the plugins your work calls for — language tools, panels, commands, shortcuts and themes. Nothing you don't use, nothing in your way. See what ships in the box.

Free for personal and educational use. One-time price for work.

No subscription, no account, no activation server. A licence is a file you import, and you can move it to another machine by importing it again.
