Build a company about the editor. JetBrains earns $200m yearly from selling IDEs, so the market is big enough to sustain development.
either go closed-source/open-core (basically, the JetBrains way)
- doesn’t allow growing a healthy community around the product
or build an open-source SaaS editor
- requires more features, collaborative editing, etc. (otherwise, why doing SaaS?)
- much harder but also is more rewarding as it allows growing a healthy community
