how to choose a Substack alternative
Easiest to get running
Listmonk — a one-click install, no server to maintain.
Most proven
Ghost, with 54,700 GitHub stars — the largest community of the 3, which usually means more answers when something breaks.
Needs real ops to self-host
Ghost is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Substack
- reader network, recommendations, app distribution, payments, and brand familiarity
- inbox-placement expertise
- advanced automations
- commerce integrations
- recommendation and ad networks

why people still pay for Substack
People still pay for Substack because newsletter operators pay for inbox placement, growth mechanics, and operational confidence on publication day. The recurring cost buys DNS authentication, reputation, bounces, complaints, unsubscribe compliance, templates, queues, analytics, backups, and support, not just the visible interface.
