Over the past few months, I’ve been building a tool I always wished existed: Wanderer – a frontend-only, no-code logic and chatbot builder, designed for privacy, transparency, and full visual control.
The idea was simple:
What if you could build complex logic for chatbots, interactive flows, or decision systems entirely visually, using just nodes and edges – with no hidden code, no backend, and no setup?
What is Wanderer?
Wanderer is a visual programming tool that lets you create GPT-powered assistants, product configurators, forms, or logic-driven conversations – all through a visual interface.
It uses a graph-based traversal engine where edges, not nodes, define the logic. The graph is executed live, directly in the browser, and reacts to changes in real time.
- No hidden code
- No global state
- No user accounts
- No server-side logic
- Just pure, visible structure = the program
What makes Wanderer unique?
- Structure = logic
The visual graph is the program. No code is hiding behind a UI. - Privacy-friendly & offline-capable
Everything runs entirely in the browser. Nothing is sent to a server. - Forkable & shareable flows
Flows are stored as clean JSON – versionable, editable, and shareable. - Reacts live & connects to GPT
You can create live GPT interactions, fire logic from chat input, and connect APIs directly from nodes.
Who is it for?
Wanderer is for anyone who wants to build logic-rich applications without writing code:
- Therapists (e.g. intake flows, structured dialogs)
- No-code makers
- Chatbot developers
- Product designers & prototypers
- Coaches, educators, consultants
- Curious minds who think in systems
Try it out
Wanderer is free to use – no signup, no tracking, no limits.
You can build, edit, test and even fork public flows directly in the browser.
