Shipmunks

Shipmunks is a free resource hub for solo founders and tiny teams building with AI tools. It answers the practical questions that come up while you build and grow: which backend to pick (Supabase vs Firebase, Convex vs Supabase, Neon vs Supabase), how to run Claude Code and AI agents, how to get a new site indexed, and how to measure money. Every guide carries something you can check yourself, like a real test, live data or a template you can copy. It also has free calculators for MRR, NRR, ARPU, CAC, CAC payback and churn rate, plus downloadable templates. No sign-up, no paywall. Written by David, a solo founder.
