CircuitSim features and specs

  • Free and accessible
    CircuitSim is a free, browser-based (and downloadable) digital logic circuit simulator, making it easy for students and hobbyists to access without any cost or licensing barriers.
  • Educational focus
    Designed primarily for teaching digital logic design, it provides an intuitive way to build and test circuits, making it popular in academic settings like computer science and engineering courses.
  • Simple, intuitive interface
    The drag-and-drop interface for placing gates, wires, and components is user-friendly, especially for beginners learning digital logic concepts for the first time.
  • Subcircuit support
    Users can create subcircuits and reuse them as components in larger designs, which helps in building more complex systems in a modular and organized way.
  • Open-source project
    CircuitSim is open-source, allowing developers and educators to inspect, modify, or contribute to the tool, and fostering community-driven improvements.

RequestBin features and specs

  • Ease of Use
    RequestBin provides a simple interface to quickly set up an endpoint to capture HTTP requests, making it easy for developers to debug webhook implementations without complex setup.
  • Real-time Monitoring
    It allows users to view the requests in real-time, enabling immediate analysis of incoming data at the endpoint, which is helpful for debugging and testing.
  • No Setup Required
    Users can create a new RequestBin endpoint instantly without any need for server configuration, simplifying testing processes.
  • Privacy and Security
    Although basic, RequestBin provides mechanisms to ensure some level of security by enabling endpoints to be private, so only those with the link can access the data.
  • Free Tier Availability
    RequestBin offers free-tier access, allowing users to try and use the service without an initial financial commitment, which is useful for small projects or individual developers.

Possible disadvantages of RequestBin

  • Limited Functionality
    RequestBin may lack advanced features necessary for complex testing or detailed analysis, such as request transformation or integration with other tools.
  • Temporary Data Storage
    Data from captured requests is stored temporarily and may be lost after a short period, which can be a limitation for users needing persistent logs.
  • Security Concerns
    Despite privacy settings, data can potentially be exposed if endpoint URLs are shared, leading to security concerns especially for sensitive information.
  • Rate Limits
    RequestBin may impose rate limits on the number of requests processed, which can restrict usage for high-throughput testing scenarios.
  • Dependency on External Service
    Relying on an external service means depending on its uptime and reliability, which could be a risk if the service experiences downtime or other issues.

Questions & Answers

As answered by people managing CircuitSim and RequestBin.

Why should a person choose your product over its competitors?

CircuitSim's answer

CircuitSim earns the choice when the constraint is the browser: students on Chromebooks, online courses, schools where IT will not install desktop software. Within that space, CircuitSim pairs true SPICE simulation with classroom licensing, private student seats that need no login, and an importer for Digilent's Multisim Live files.

What makes your product unique?

CircuitSim's answer

CircuitSim runs a real SPICE engine entirely in the browser. Simulation results match what desktop SPICE tools produce, with nothing to install. On top of the simulator there is a large searchable component catalog and classroom groups with private student seats: a teacher shares a join link and students work without creating accounts, which keeps classes clear of the student-privacy problems that come with provisioning accounts. CircuitSim also imports designs from Digilent's Multisim Live, which matters right now because Digilent is retiring Multisim Live in September 2026.

How would you describe the primary audience of your product?

CircuitSim's answer

Educators and students, mostly. The core user teaches circuits somewhere that desktop software is not an option: community college electronics programs, university ECE labs, online courses, and K-12 engineering classes where students are on Chromebooks. Outside the classroom, hobbyists and working engineers use CircuitSim for quick analog and digital simulation without installing anything. A large share of new users right now are instructors moving their courses over from Digilent's Multisim Live before it retires in September 2026.

Who are some of the biggest customers of your product?

CircuitSim's answer

Community college electronics and engineering technology programs University ECE departments running browser-based circuit labs K-12 engineering and CTE courses on Chromebooks Instructors migrating classes from Digilent's Multisim Live ahead of its September 2026 retirement

  • Testing Webhooks and Events Using Mock APIs
    Visit Mockbin.io, Beeceptor or RequestBin and click "Create endpoint." These platforms instantly generate a unique URL that captures incoming HTTP requests. Copy the provided URL, something like https://your-webhook-endpoint.com/hook. - Source: dev.to / about 1 year ago
  • Show HN: Rap song generate by Chat GDP based on recent NYTimes Article
    That's a fun example, because ChatGPT doesn't actually have the ability to fetch the contents of a URL. So it produced that summary (and the lyrics) entirely based on guessing the content of that URL! You can prove this to yourself by pasting in a URL to a site you own and watching the web server logs, or by using something like https://requestbin.com/. - Source: Hacker News / over 3 years ago
  • free-for.dev
    RequestBin.com — Create a free endpoint to which you can send HTTP requests. Any HTTP requests sent to that endpoint will be recorded with the associated payload and headers so you can observe requests from webhooks and other services. - Source: dev.to / almost 4 years ago
  • How to listen to webhooks
    But that said, if all your want to do is receive the hook and look at it, you can set it up using https://requestbin.com/ which will allow you to do exactly that. Source: about 4 years ago
