Side project billingUpdated Jul 7, 2026

Billing for side projects

A practical guide to charging for small developer products with checkout, wallets, credits, webhooks, and billing UI handled by neonFin.

For developers who have a useful tool and want to charge for it without spending a week wiring billing infrastructure.

No-auth monetizationUpdated Jul 7, 2026

Monetize a tool without user accounts

Use anonymous credit wallets and recovery codes to sell access to small tools without adding a full auth system first.

For tools where forcing signup would add more friction than value, but users still need to buy and restore access.

Payment UIUpdated Jul 7, 2026

shadcn payment components

Install payment UI into your own codebase: balances, purchase dialogs, wallet recovery, credit gates, and feature gates for developer products.

For shadcn users who want billing UI that can be installed, inspected, themed, and changed instead of imported as a black-box widget.

Self-hosted billingUpdated Jul 7, 2026

Self-hosted payment layer

Run one small payment layer for all your side projects while Stripe or Polar keeps handling checkout, invoices, taxes, and payment methods.

For developers who want payment infrastructure they can run, inspect, and reuse across multiple apps.
