Show HN: Flowcode – Turing-complete visual programming platform

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 services with basic logic. Flowcode is meant to speed up and simplify those tasks, leaving more time to think about design and solve design problems. Visual programming also works really well for developing workflows involving LLM calls that are non-deterministic and require a lot of debugging and prompt tweaking.

There are many other visual/low code tools, but they all offer limited control and flexibility (no concurrency, loops, transparency) and most suffer from the same problems (vendor lock-in, hard to integrate with existing code etc.).

Flowcode is built on an open source visual programming language (Flyde https://github.com/flydelabs/flyde, which I launched last year here on HN - https://news.ycombinator.com/item?id=39628285). This means Flowcode has true concurrency, no vendor lock-in (you can export flows as .flyde files), is Turing-complete (loops, recursion, control flows, multiple IOs etc.), lets you fork any node, integrates with code via an SDK and more.

I’d love to hear your thoughts and feedback.
