I didn't see a public source repository for keet, just compiled releases. Why would you trust closed source for a privacy app?

I’ve talked to their devs/met them in person and trust them, most of their stack is public/all the primitives they use are available and well documented (see https://github.com/holepunchto and https://docs.pears.com/), I’ve used that stack and verified it does what is advertised, and I believe they’re planning a full open source release of the parts that aren’t already public.
