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
Try it now
Go to: wanderer-flow.de
No signup required. Try the builder or fork one of the included examples.
I’d love your feedback
- What’s clear or confusing?
- What would make it more useful for you?
- Would you use this for anything?
Thanks for reading!
Chris
