Visual Logic Without Code - Can This Change the Way We Build Flow-Based Systems?

SteamPixel — Mon, 07 Jul 2025 12:08:44 +0000

What if logic wasn’t hidden behind blocks – but was the blocks?

With Wanderer, I’ve built a free visual flow builder where the logic is the structure.

No function bodies. No hidden scripts. Just nodes and edges - and a graph that executes itself in real time, right in your browser.

You can build things like AND, OR, XOR, and NOT gates - all 100% no-code.

🧠 The twist?
Edges are the logic. They define behavior, and the whole system reacts live.

🎯 Try the interactive logic gate demo (no login): https://wanderer-flow.de/builder?flow=https://wanderer-flow.de/flows/logic/different-logical-gates.json

It’s for builders, educators, and anyone curious about what visual programming can become when it’s truly visual.

Let me know what you think – and what you'd build with it.

Hey Dev.to 👋

I’ve been working on a side project that started from a simple frustration:

I just wanted to build a chatbot

but every tool forced me to write complex code, bury logic inside nodes, or sign up for yet another cloud service.

So I built my own.

Introducing Wanderer Flow – a reactive, visual, and open flow engine that runs 100% in the browser.
No backend. No login. Just open a tab and start building.

What makes it different?

Flow-based: You build logic by connecting nodes and edges, not writing scripts.
Reactive: The flow is constantly traversed, like a living system.
No server: It’s fully client-side. Nothing gets uploaded. You own your data and logic.
Fork & share: Every flow can be exported as JSON or shared via URL.
GPT support: You can add GPT nodes, define your own prompts, and react to responses in the graph.
Instant preview: The flow runs while you’re building. You see your changes live.

Example use cases

Chatbots that adapt to changing context (like weather or inputs)
Interactive decision trees
Lightweight, offline-ready AI agents
Guided flows for websites or tools — without backend dependencies

Tech stack

Nuxt3 / Vue / Tailwind/ Vanilla JS / TypeScript
Open source (soon on Codeberg)
Designed to run on the edge, Raspberry Pi, or inside any CMS
