The Verdict
Botpress is built for customer support teams and developers, with a focus on visual-flow-builder and knowledge-base. Signal targets privacy advocates and journalists and leads with end-to-end-encryption and group-chats.
Signal uses custom enterprise pricing, while Botpress starts at $79/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Bottom line: Signal has a slight overall edge — but if visual flow builder is intuitive matters most to you, Botpress may still be the right call.
