Flyde – an open-source visual programming language
Hi HN! I’m Gabriel, and I’m happy to share a project I’ve been working on for the last few years: Flyde, an open-source visual programming language. Check out the interactive examples and online playground on the website: https://www.flyde.dev. In my last role as an engineering manager for a B2B-oriented product, I authored and reviewed many diagrams for backend applications, mostly for integrations between 2 third-party services. Some of these diagrams were elaborate enough that I started dreaming of a way to simply run a diagram as is; I imagined a “run” button on the top-right…
Flyde – an open-source visual programming language launched on March 7, 2024 with 298 votes, #129 of 4,270 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
Flyde is an open-source visual programming language that allows developers to create and execute programs by drawing diagrams rather than writing code. It targets backend developers and integration specialists who work on connections between third-party services. The software includes an interactive online playground and examples, enabling users to design workflows visually and run them directly without translating diagrams into traditional code.

Ecode – A minimalist and fast open-source code editor2023 · github.com · ▲233Hi HN! I've been working on a code editor and I think that it's mature enough to catch some interest. It's using a custom GPU accelerated GUI written in C++. Currently implements some interesting features: LSP, terminal, auto-completion, linters, formatters, custom keybindings, plugins and more. It's a hobby project but still intends to be an alternative to other popular code editors like Sublime, Kate, Lapce, Lite XL (and takes inspiration from them). The project was born as a playground for the GUI I'm developing (eepp GUI) and is advanced enough to currently be my main code editor, but…
- FGFlyCode – Git-Based Copy and Translations Editor for Web Apps2022 · flycode.com · ▲185
Hi HN community, Over the last six months, we’ve been building FlyCode, a product editing DevTool. We make it easy for team members to edit product copy in web and native apps’ code through FlyCode’s dashboard with auto-generated PRs instead of using a code editor. From the beginning, we built around the belief that codebase ownership should stay with developers and that tools should flexibly coexist with a codebase rather than dictate infra changes. The key shift for us was to identify ways to include non-technical teams as individual contributors in the development process. At FlyCode,…
- FTFlowcode – Turing-complete visual programming platform2025 · app.getflowcode.io · ▲176
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…
- AVA Visual IDE for React2022 · dev.aspect.app · ▲479
I made this because building UIs in a lexical medium like code is super annoying. I have to pre-render what I’m making in my head, and then jump between the browser and IDE to test. I was inspired by the developer console in chrome and safari since I end up editing css there because it’s ironically more convenient. Hope it’s useful!

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
