Create diagrams of complex data flows in software systems
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…
Create diagrams of complex data flows in software systems launched on July 26, 2024 with 205 votes, #270 of 5,184 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
This tool helps software engineers visualize complex data flows in software systems through dynamic, interactive diagrams. Rather than using text-based syntax like Mermaid, users can create flowcharts more intuitively and quickly, inspired by game mechanics from titles like Factorio. Designed for developers who struggle to explain how data moves through Rube Goldberg-like systems, it aims to make diagram creation faster and more accessible than conventional alternatives.

Diagram as code tool with draggable customizationsOct 2025 · github.com · ▲266In 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…

Many years ago, I made VJ softwares (to mix live visuals in clubs) for unexpected platforms like the Game Boy Advance, the Playstation 2 and the Raspberry Pi. This year, I’m back with a new web-app: Pikimov. Inspired by Photopea (a free Photoshop clone), I created this web-based motion design & video editor as an alternative to After Effects, to fill empty void. It's free, without signup, without cloud uploads (your files stay on your machine), and your projects are not used for AI models training.
