The Verdict
Novu is built for saas developers and product teams, with a focus on multi-channel-notifications and notification-center. Signal targets privacy advocates and journalists and leads with end-to-end-encryption and group-chats.
Signal uses custom enterprise pricing, while Novu starts at $0.0025/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.
Feature-wise, Novu offers broader built-in capabilities (7 features vs 6), while Signal takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Signal has a slight overall edge — but if single api for all notification channels matters most to you, Novu may still be the right call.
