“No official API for building on top of Signal. The protocol is brilliant but the platform is intentionally closed.”
“The best encrypted messaging app. Zero compromise on privacy. But it's a user tool, not a developer platform.”
“The Signal Protocol is the most important encryption innovation of the decade. Every major messenger uses it.”
