TL;DR
Indie Kit Pro is built for indie founders who want to monetize fast: credits, a page to redeem lifetime-deal codes, and more payment providers than almost any other starter. supastack is built as a foundation for products that grow into teams, mobile apps and integrations.
- Pick supastack for B2B products, teams, mobile or desktop apps, API integrations, and a codebase with real tests.
- Pick Indie Kit Pro for a web product sold with credits or lifetime deals, especially if you need Paddle, PayPal or Dodo Payments.

Integrations and trust features — API keys, signed webhooks, audit log, GDPR export, admin impersonation and bans.
AI cost control — per-workspace BYOK keys and usage budgets.

Credits and lifetime deals — a credits system with expiry and history, plus a built-in flow to redeem lifetime-deal codes, useful for AppSumo-style launches.
Launch pages — waitlist, blog and docs are ready for launch day.
