FlowRun
Title says it all, you can make a flowchart and run it in your browser. I hated it in school when we were just drawing these on a piece of paper.. Only later when we started with Pascal it kinda clicked to me. It is mostly intended for teaching basics of programming. Used in lots of schools all around the world. Gets around 500 daily users. There is a series of interactive tutorials: https://flowrun.io/tutorials Also a free ebook: https://leanpub.com/learnprogrammingwithflowrun Editor is open source: https://github.com/sacode387/FlowRun…

What it does
Interactive visual editor for making programs. Works in any browser. Generates real-world code for many popular programming languages.
FlowRun - runnable, executable flowcharts. Visual programming. Visualize complex flows and algorithms
Start in the scratchpad, keep learning with tutorials, then use the open learning hub for docs, the paperback, and optional support. My students love the FlowRun app because it's possible to run the flowchart (not just draw it), so they can follow the execution and find bugs in an easier way. I'm using it in 3 of my classrooms with great results. The concepts were understood faster and the automatic code generation is very nice. It is a lot easier to teach flowcharts theory by making examples in a very fast way. I'm using FlowRun with my highschool students with great success. Since Flowrun runs in browser it's very useful for students who often don't have a computer. The most intuitive way…from flowrun.io

Hey HN! I’m Gabriel, and I’m excited to share a project I’ve been working on for the last few years. Flowcode is a visual programming platform that tries to combine the best of both worlds (code and visual). Over the years I found myself repeatedly drawing architectures and logic. It was always my dream to just press “run” instead of having to write them in code afterwards. But none of the visual tools I found were flexible and transparent enough for building real products. I think that visual programming fits perfectly with modern backend dev tasks that revolve around connecting different…

SpeedVitals▲829Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals. Until now, our platform has only focused on Synthetic/Lab testing, such as Lighthouse tests and TTFB tests. But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits. Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
