The Verdict
Flowise is built for developers and startups, with a focus on visual-builder and llm-chains. Relay.app targets operations teams and agencies and leads with workflow-builder and ai-steps.
Pricing is close: Relay.app starts at $16/mo versus $19/mo for Flowise — not a deciding factor on its own.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Flowise offers broader built-in capabilities (7 features vs 6), while Relay.app takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
