Hi There, Erlang-RED has been my project for the last couple of months and I would love to get some feedback from the HN community. The idea is to take advantage of Erlangs message passing and low overhead processes to have true concurrency in Node-RED flows. Plus also to bring low-code visual flow-based programming to Erlang.

This is a recent addition to Vexlio which I think the HN crowd may find interesting or useful. TL;DR: easy creation of interactive diagrams, meaning diagrams that have mouse click/hover hooks that you can use to display pop-up content. The end result can be shared with a no-sign-in-required web link. My thought is that this is useful for system docs, onboarding or user guides, presentations, etc. Anything where there is a high-level view that should remain uncluttered + important metadata or details that still need to be available somewhere. You can try it out without signing up for…

In the past I've used declarative diagram generation tools like Mermaid.js a lot for quickly drawing up things but for presentations or deliverables I find that I have to then move the generated diagrams over to a tool like Lucidchart which allows full control of the organization and customization. Therefore I am now working on this to combine the benefits of both into just one tool which can do both functions. The project is certainly in the early stages but if you find yourself making architecture diagrams I'd love to hear your thoughts on the idea or even a Github issue for a feature…

Hi HN! I’m Alex from Parabola (https://parabola.io). Parabola is a visual programming tool for creating functional data flows that everyone can use. It’s entirely drag-and-drop, handles data sizes much larger than a traditional spreadsheet, calculates everything live, and can run your flows on a schedule of your choosing. I used to work in strategy consulting, doing data analytics for SMBs and Fortune 500 companies. The amount of time wasted on menial tasks was astounding. Things like cleaning data, generating custom reports, creating human workflows to solve shortcomings in third…

Hello HN, It has been a while since I contributed to the web, so I decided to get back in shape and publish "something". This app is a POC of "what if diagrams were more dynamic". I'm a software engineer by trade, and with conventional tools, I often times struggle to explain flows of data in complex software systems. I got inspired by video games like The Incredible Machine and Factorio, as in some ways, software systems tend to become Rube Goldberg-esque machines ;) As a side quest, I also wanted to craft diagrams faster than text-based tools (ex: mermaid), as I am always forgetting their…

Hi HN folks, I'm a co-creator of the Dapr CNCF project and co-founder of Diagrid. Today we announced a free-to-use web app that takes any form of workflow diagram (UML, BPMN, scribble in your favorite drawing tool or even on paper) and generates code that runs in any IDE and that can be deployed to Kubernetes and other container based systems, based on Dapr's durable execution workflow engine. This essentially allows you to run durable workflows in minutes and leaves out the guesswork for how to structure, code and optimize a code-first workflow app. I'm happy for you to give this a try and…
