Total monthly cost
$28/month + $99/year (Apple Developer Program)
For comparison: a typical "indie hacker stack" runs $200-500/month. The trick is staying with tools that do one thing well, not buying the all-in-one platforms.
What I'd add if revenue justified it
ConvertKit / Beehiiv — better email automation than Substack ($29-79/mo). I'd switch when paid tier subscribers > $300 MRR.
Stripe — direct checkout for $500+ products. Currently Gumroad's 12.9% fee is acceptable for catalog scale.
Apple Search Ads — $30-100/day campaign. Worth testing at Day 90+ if cumulative iOS revenue exists.
Customer.io — drip email sequences. Worth at $1000 MRR.
What I'd skip
Webflow / Squarespace — GitHub Pages + plain HTML beats them at indie scale.
Notion-as-CMS — frontmatter + scanner is faster.
SEO tools (Ahrefs / SEMrush) — at $100+/mo, not justified until cumulative content > 200 articles.
Customer support platforms (Intercom, Zendesk) — email is fine until > 100 customers.
