Quick answer
micro-jaymock - Micro-jaymock wins for most solo builders who just need a no-friction mock endpoint, while Mockfly wins when you need a hosted mock server with project structure, logging, and room to grow.
How the free tiers compare
The core difference is simplicity versus productized workflow. micro-jaymock is basically a public API for generating fake JSON from a template. There is no paid ladder in the data, no signup friction, and no credit card requirement, so it is best when you want to paste a template, get mock data back, and move on. Mockfly is a more traditional mock API platform. Its free tier is capped at 500 requests per day, 1 project, 4 endpoints, and 2 responses per endpoint, but it adds hosted-server features like request logging, version history, and auto-generated docs on the paid side. If you are evaluating free tiers only, micro-jaymock is the lighter tool. If you expect to manage multiple endpoints, teammates, or a longer-lived mock setup, Mockfly is the more complete product, even if the free tier is tighter.

After you outgrow the free tier
micro-jaymock has no paid plans in the provided data, so there is no documented upgrade path or pricing model to compare. Mockfly starts at a flat 8€ per month on the Profesional plan, with an annual option of 88€ per year. That makes Mockfly the product with a clear cost curve after free: once you need unlimited requests, projects, endpoints, or responses per endpoint, you move to a fixed monthly fee. For small teams, Mockfly is predictable but not free; micro-jaymock stays cheaper in the input because it remains always free.
When to pick each one
Pick micro-jaymock when…
- You want a quick fake JSON response from a JSON template with minimal setup.
- You are prototyping a frontend and only need a public endpoint for sample payloads.
- You prefer an always-free tool with no known paid cliff in the provided data.
- You want to test a one-off integration without managing projects or endpoint counts.
Pick Mockfly when…
- You need a hosted mock server with projects, endpoints, and multiple responses per endpoint.
- You want request logging, version history, or generated API docs as part of the workflow.
- You expect to outgrow a small free cap and want a clear paid upgrade path.
- You are working on a team and need the product to support more structured mock API management.
Bottom line
For the most common builder use case, micro-jaymock is the better free-tier pick if you just need to generate mock JSON quickly and do not want to think about limits or upgrades. Mockfly is the better choice if you are treating mocking as a shared workflow and need a hosted product with endpoint management, logs, and a real paid path once the free cap gets tight. In short: micro-jaymock for speed, Mockfly for structure.
