Kascade vs Substack

The modern alternative to Substack.

Substack is a newsletter tool — it reaches inboxes, but it isn't a system for product knowledge. Kascade connects blog, release notes, changelog, and docs on one source of truth, on your domain, kept current as the product changes.

Comparison

Kascade vs Substack

Substack is excellent for paid newsletters, but a newsletter is one surface. Your changelog, release notes, and docs live elsewhere, and there's no way to keep them aligned when the product ships. Kascade structures one input into every surface, keeps them current, and handles migration and hosting for you — at flat pricing, no revenue cut.
