The Verdict
Kong is built for platform engineers and microservices teams, with a focus on api-gateway and service-mesh. Penpot targets open source teams and privacy focused designers and leads with vector-editing and prototyping.
On pricing, Kong is the clear winner for budget-conscious users — starting at $0.05/mo compared to $8/mo for Penpot. That $7.95/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Kong offers broader built-in capabilities (8 features vs 7), while Penpot takes a more focused approach — which can mean a simpler, faster onboarding experience.
