Ghost vs Substack

Self-hostable open source versus closed distribution network.

What matters for early-stage startups

At an early stage the deciding factors are what the free tier actually covers, what the first paid invoice looks like, and how much of a founding engineer's week the setup costs. Feature depth that only matters at a million sends a month is noise until it is not.

Priority Ghost Substack
Free tier Self-hosted is free (your infra cost) Free, 10% of paid subscriptions
Best published rate per 1,000 Tiers not published in comparable form Tiers not published in comparable form
Starts at Ghost Pro from $9/mo 10% revenue cut
DX score 7/10 2/10
Deliverability Depends on the SMTP provider configured (often Mailgun for Pro). Reasonable for content-driven newsletters.
Operating since 2013 2017
Scheduling Yes Yes
SDKs node None
Webhooks Yes No

For a pre-revenue or early-revenue team running a waitlist, a launch announcement, onboarding email, and the first transactional sends, Ghost takes every priority that separates them here (developer experience, operating track record, SDK breadth, and webhook coverage), while Substack matches it on the rest. On free tier, Ghost offers Self-hosted is free (your infra cost) against Free, 10% of paid subscriptions from Substack. That ordering reflects this audience. Weigh the same table differently and the answer changes.
