Best for
Writers who want a minimalist, federated blog and happy to send emails via Listmonk.
WriteFreely strengths
- Deliberately simple — no trackers, no analytics, no bloat.
- ActivityPub support, so posts federate into Mastodon.
- Runs as a single Go binary.
WriteFreely weaknesses
- Not a full newsletter tool — pair with Listmonk for email sends.
- No paid-subscription or Stripe integration out of the box.
- Theming options are intentionally limited.
What's the catch with Substack?
- 10% revenue cut is expensive at scale vs. self-hosted Ghost or Listmonk.
- Content moderation policies have pushed some creators off-platform.
- You don't own your mailing list the same way you would on your own infra.
