Wayfinder Router is an open-source tool that deterministically routes queries between local and hosted large language models. Developers define rules to decide which requests go to a local model and which to a hosted API like OpenAI. This approach balances privacy concerns with computational power, keeping sensitive data local while leveraging cloud models for complex tasks. The tool is available on GitHub under the MIT license.


Wayfinder Router is a quiet revolution. It gives developers control. They decide what data stays private and what goes to the cloud. No more black-box routing. No more trusting a single provider with everything. This is sovereignty in the age of AI.

Think about it. Local models for sensitive documents. Hosted models for creative writing. The router makes this seamless. It’s like having a smart switchboard for your AI queries. Privacy doesn’t have to mean compromise. Power doesn’t have to mean exposure. Wayfinder Router bridges that gap.
