The short version

  • Only Asyncapi has a free tier, so it costs nothing to try first.
  • Each has a real cost: Asyncapi complex to implement and debug asynchronous operations due to their non-linear and concurrent nature; Razorpay international card payments cost up to 3% per transaction versus 2% domestically, per razorpay.com/pricing (Aug 2026), and an 18% GST is added on top of the platform fee

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Asyncapi

  • Complex to implement and debug asynchronous operations due to their non-linear and concurrent nature
  • Keeping AsyncAPI documents up to date is challenging as systems evolve
  • Tracing and debugging asynchronous operations is more difficult than synchronous request-response patterns

Razorpay

  • International card payments cost up to 3% per transaction versus 2% domestically, per razorpay.com/pricing (Aug 2026), and an 18% GST is added on top of the platform fee
  • Instant refunds cost between Rs. 7.99 and Rs. 14.99 per refund on top of the transaction fee, per Razorpay's own pricing page; standard refunds are free but instant ones are not
