The Verdict
Miro is built for designers and product teams, with a focus on whiteboard and templates. Spline targets web designers and product designers and leads with 3d-modeling and real-time-collaboration.
Pricing is close: Miro starts at $8/mo versus $9/mo for Spline — 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, Spline offers broader built-in capabilities (7 features vs 6), while Miro 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.
