Requestly over Mockoon

1. Simple, Fast & Powerful

Creating mocks in requestly is very easy with cloud-based mocks. You don’t need to install any binary and mock works outside of your local system.

More Powerful than ModHeader

2. Gentle Learning Curve

Requestly is designed from bottom up to maintain a shallow learning curve. Moreover a detailed documentation, a learning academy, interactive guides & video tutorials make you a power user from Day 1.

3. Completely external to Codebase

Using HTTP Rules Requestly can intercept and override actual APIs, resulting in zero code changes. Not even hostname change required. Active Toggle with HTTP Rules makes switching between Mock and Real APIs a piece of cake.

4. Collaboration

Requestly is designed for teams and, hence, makes collaboration very smooth. You can work with your team in a common/shared workspace. You can also create and share groups for easy organization of HTTP rules.

5. API Mock Collections

Collections of Mock APIs help group APIs and serve them from a single endpoint. This enables you to mock a service completely.

6. Pre-built Mocks

Pre-built Mocks help you setup a mock with any manual work. Mocks with different status codes can be easily configured using these pre-built mocks like 4xx, 5xx, 2xx, etc.

7. Best Customer Support

Requestly is known to provide the best customer support to its customers. This is evident in the more than 1000 reviews on the Chrome Store testifying to the best support from the Requestly team.

8. Enterprise Ready


Requestly is enterprise-ready software, prioritizing security and organizational control with features like SSO, Team Management, SLAs, SOC-II compliance, Reporting and analytics, and Role-based access control.

9. GraphQL Support

Exclusive support for GraphQL APIs is available in Requestly. Unlike Mockoon, which is designed for REST APIs and struggles to handle GraphQL’s request structure. GraphQL relies on a schema-based approach, making it necessary to apply additional filtering to isolate specific operations within a request.
