Problem: handles subscriptions, billing, webhook verification and reconciliation, focused on Next.js and Python. Audience: SaaS and content builders adding paid subscriptions. Stack & setup: Python, configure merchant credentials and keys; webhooks need signature checks, idempotency and amount validation, difficulty medium-high. Difference: it currently appears in only one source (GitHub), so cross-checking is advisable. Risk: permissive terms still require preserving copyright and license notices, and trademark/patent clauses may apply.
