Your flows adapt in real-time to changing conditions. Time-based offers, dynamic questions, context-aware responses—like real conversations should be.

Privacy by design

Runs fully in the browser. No data sent to our servers unless you choose to. Ideal for GDPR compliance, healthcare, or sensitive applications.

Open Source

No vendor lock-in. Export as JSON, host anywhere, share via URL. Your knowledge stays yours—fork, modify, redistribute freely.

AI can build flows for you

Flows are text-based JSON—no visual-only interfaces. GPT and other LLMs can generate, modify, or understand your flows directly.

Debug in real time

Watch your flow execute live as you build it. See which nodes fire, which edges are traversed, and what states change—all visualized directly in the editor.

Start instantly—no signup

No email, no registration wall. Just open your browser and start building.

Start building in 3 steps

1

Add nodes & connect them

Drag messages, questions, suggestions, and other nodes onto your canvas. Connect them with edges to define the flow.

2

Set conditions on edges

Use May, Must, and Not edges to create logic structures. No scripting — just pure visual connections.

3

Test & share instantly

Watch your flow execute live in the built-in chat. Share via URL or embed on your site.

Start free, upgrade when you grow

Build and share unlimited flows for free. They're yours— host them anywhere, fork them, inspect them.

Upgrade to embed on your website, remove branding, track analytics, or use our managed hosting.

Why we built this differently

Most chatbot builders hide their logic behind code and black boxes. We believe conversations should be transparent, knowledge should flow freely, and privacy should be the default—not an upgrade.

Wanderer runs entirely in your browser. No servers. No tracking. No vendor lock-in. Just open, visual logic you can see, share, and own. Because powerful tools shouldn't come with compromises.
