Mocklets is a HTTP-based mock API simulator, which helps simulate APIs for faster parallel development and more comprehensive testing.

Mocklets enables you to stay productive when an API you depend on doesn't exist or isn't complete. It supports testing of edge cases and failure modes that the real API won't reliably produce.

Possible disadvantages of Cal.com

  • Learning Curve
    Although it is highly customizable, the plethora of options and features may result in a steeper learning curve for new users who are not familiar with such scheduling tools.
  • Limited Free Version
    The free version of Cal.com comes with limitations that may not be sufficient for growing businesses or advanced users who require more comprehensive features.
  • Dependency on Integrations
    Cal.com's effectiveness heavily depends on its integrations. Without these integrations, some users might find the tool less useful or incomplete, especially if their primary tools are not supported.
  • Support
    While open-source has many benefits, it may also mean that immediate, personalized support could be limited compared to fully commercial solutions. This might pose a challenge for users needing quick resolutions.
  • Performance
    As an open-source platform, the performance might vary depending on how it is hosted and managed. Suboptimal configurations could lead to slower performance or downtimes.

Mocklets features and specs

  • Easy API Mocking
    Mocklets allows developers to easily create and manage API mocks, which can be extremely beneficial during the early stages of development when the actual APIs are not yet available.
  • Supports Automated Testing
    With Mocklets, you can simulate different API responses which is useful for automated testing, ensuring that your application handles various scenarios and errors gracefully.
  • Scalability
    Mocklets can handle high traffic loads, making it suitable for testing environments that need to simulate a large number of API requests.
  • Free Tier Available
    Mocklets offers a free tier, allowing developers to get started without financial commitment. This is great for individual developers or small teams.
  • Customizable Responses
    Developers can configure Mocklets to return specific responses based on request parameters, which aids in testing different application paths without changing the backend.

Possible disadvantages of Mocklets

  • Limited Features in Free Plan
    While there is a free plan, it comes with limitations such as restricted requests per month or limited concurrent mocks which might not suffice for larger projects.
  • Not a Full Replacement for Live APIs
    Mocklets is useful for simulating API responses but cannot fully replace the need for testing with live APIs under real-world conditions.
  • Learning Curve
    New users might encounter a learning curve when getting acquainted with the setup and customization of API mocks, potentially impacting the initial productivity.
  • Service Dependency
    Relying on an external service like Mocklets introduces a dependency which might not be ideal for projects requiring high security or offline capability.
  • Performance Overhead
    Although the service is scalable, adding a mock layer can introduce minor latency and performance overhead, which should be considered in performance-critical applications.

I tried using https://cal.com for a bit but ended up just switching over to https://zcal.co and it has been great so far. All these other scheduling tools end up trying to do too much and always seem to end up a bit clunky and charge absurd amounts for it

    Then, I came across Cal.com, a fantastic open-source project for scheduling meetings and managing tasks (super useful for productivity!). I knew the basics of Git but wasn’t quite there with forking, merging branches, and all the intricate Git processes. After some YouTube tutorials, I started to get the hang of things. 😅. - Source: dev.to / 7 months ago

  • Fellow HSP entrepreneurs, how do you manage your energy and stress?
    I force clients who want to talk to me to book a call. I use cal.com (free) and my Google Calendar (which its linked to) only allows calls on specific days/times. I have a few "Call Blocks" where they can book. That let's me do calls in a small section of my week, with ample downtime to recover the rest of the week. I'm still learning how many calls a day I can handle. Currently anything more than 2 is too much. Source: over 1 year ago
