Download OctoEdit

Which package is which

• 🧾

  Windows

  A zip archive: unpack it anywhere and start OctoEdit.exe. The HTML preview add-on is a separate download that adds the live browser-based preview of HTML and PHP documents; install it from Plugins inside OctoEdit.

• 🍎

  macOS

  A disk image: drag OctoEdit to Applications. Two packages are published that differ in one thing only — with the HTML preview bundles the browser engine for the live HTML preview and is considerably larger; without is the same editor with that one feature left out.

Everything else is identical, and your preferences and saved session live outside the application, so you can switch packages at any time. Details: the HTML preview in the documentation.

System requirements

• 🧾

  Windows

  Windows 10, version 1809 (build 17763) or later, 64-bit. Needs the Microsoft Visual C++ 2015–2022 Redistributable (x64), which most systems already have.

• 🍎

  macOS

  macOS 14.4 Sonoma or later on Apple Silicon. Every Mac with an M-series chip is supported; Intel Macs are not.
