    Postman vs Requestly Comments
    Abhishek Sachan
    Positive

    I think Requestly is coming up as a strong alternative to Postman. The power of request interception and modification combined with an API Client really simplifies the workflow. The major concern with Postman is its closed source is also resolved by Requestly being an Open Source project. I would rather pay for Requestly a single tool instead of paying for 2 tools to intercept and modify the request and API Client.
