CircuitSimCircuitSim'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.
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.
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.

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
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
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
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
Visit Request bin and create a new bin. Once created, copy the bin URL and paste it into the webhook field. - Source: dev.to / about 4 years ago
