Need advice: Any good platforms for unlimited mock APIs during local dev/testing? (Paywalls on existing tools are annoying)

Hey everyone,

I'm currently in the middle of building and testing my project, and I heavily rely on mock APIs to simulate endpoints, edge cases, and response payloads for frontend integration.

The problem is, most popular mock API tools/platforms out there quickly hit me with heavy rate limits, request caps, or paywalls on their free tiers just when I'm in the flow of heavy testing. Paying hefty monthly subscriptions just to mock endpoints during the early dev phase feels overkill.
