Fountain native
- Inkwell
- Slugline
Lean Fountain on Apple devices vs room-ready IDE.
Slugline is intentionally small — Fountain in, PDF out, on Mac and iOS, with almost no UI chrome. Inkwell is the opposite end of the spectrum: a full IDE with version control, collaboration, production-oriented workflows, and AI skills. Compare honestly for your workflow.
Credit where the competitor is genuinely strong

When the script grows up — version history, room collab, and production pipeline in one IDE.

Slugline fits solo Apple writers who want the thinnest Fountain tool. Inkwell fits professionals and rooms who outgrow a single file — parallel takes, reads as save points, and FDX handoff.
The Free plan includes the full editor and AI skill passes.
