Limits

This is pre-1.0. Nobody has independently audited it. X-Wing is still an IETF draft. I am the only maintainer.

The CLI stays free. I am not selling a hosted version.

About

I came from electrical and electronics engineering into software. Sindook is the only product I am building now.

Other work

I still keep these online. They are not the product.
