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…

I built Nogic, a VSCode extension currently, because AI tools make code grow faster than developers can build a mental model by jumping between files. Exploring structure visually has been helping me onboard to unfamiliar codebases faster. It’s early and rough, but usable. Would love feedback on whether this is useful and what relationships are most valuable to visualize.

I've been programming since I'm 6 and I don't want to quit. Since Agents came into existence I've been increasingly building more of the random ideas. BUT, like many I kept getting stuck and frustrated where I wanted to make changes with the Agent that I knew I could've made without it but I had *no clue* how things worked. I created Intraview to help me build and maintain a mental model of what I was building (or had vibed) so I could use my knowledge to either fix it myself, or provide more directed instruction. It grew into something that's transformed my workflow in a pleasant way.…

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…
