Is Primer really free or is there a hidden fee?
Primer offers a free plan for sandbox and development use, but live payment processing typically requires a paid plan, often based on transaction volume and features. You should check Primer's official pricing page for current tiers and any volume-based fees.
Can I use Primer to switch from Stripe to Adyen without rewriting my frontend?
Yes, that's a core feature. With Primer's unified API, your frontend stays the same while you manage processors and routing rules on the backend, so switching providers doesn't require frontend code changes.
