Best Free Screenwriting Software
for Windows, Linux & Mac.

Finding high-quality, completely free screenwriting software can be a challenge. Many legacy scriptwriting tools require expensive recurring subscriptions, place watermarks on your exported PDFs, or lock your scripts behind proprietary formats. Fortunately, the rise of Fountain—the open plain-text screenplay format—has sparked a revolution in modern screenplay software.

Whether you write on Windows, Linux, or macOS, you no longer need to pay hundreds of dollars to draft industry-standard screenplays. In this guide, we evaluate the best free Fountain screenplay editors available in 2026, comparing their features, platform support, and offline capabilities.
