The short version

  • ProtoPie is a tool for creating highly interactive prototypes without coding.
  • Free plans on both; paid from $25/mo and $300/mo.
  • Only ProtoPie lists interactive prototyping; only Restate lists durable execution.
  • Where ProtoPie falls short: the free plan allows 2 prototypes, 8 scenes per prototype and 50MB of cloud storage.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ProtoPie

  • The free plan allows 2 prototypes, 8 scenes per prototype and 50MB of cloud storage
  • Free prototypes carry a watermark and shareable links require the Basic plan
  • Saving prototypes locally requires the Pro plan
  • Team libraries and handoff recordings require the Pro plan
  • Basic caps storage at 500MB and prototypes at 20
  • Single sign on, private servers, custom fonts and custom hardware integrations are Enterprise only
  • Enterprise requires a minimum of 3 seats and is priced by quote
  • Connect Core is a paid add on at $20 per user per month

Restate

  • The runtime is under a Business Source Licence rather than an open source licence, so building a competing managed offering on it is prohibited and some procurement functions will reject it on licence grounds alone
  • Restate Cloud jumps from a free fifty thousand actions straight to 300 US dollars a month for twenty million, so a workload sitting at a few hundred thousand actions pays enterprise-shaped money for hobby-shaped volume
  • It is a young project against Temporal’s established base, so hiring engineers who already know it is unrealistic and the answer to most questions is in the docs rather than on Stack Overflow
  • The programming model requires structuring code around durable handlers and virtual objects, which is a genuine rewrite for existing services rather than a library you add
  • The single-binary simplicity that makes small deployments cheap also means fewer operational knobs at very large scale than a system designed as separable components

Answered from the vendors’ own pages

ProtoPie: How much does ProtoPie cost?

ProtoPie offers a free plan ($0/month), Basic at $25/month, and Pro at $47/month per editor. Annual billing offers up to 26% savings. Enterprise pricing is custom for minimum 3 seats.

Source
Restate: Is Restate open source?

The SDKs are MIT. The runtime is under a Business Source Licence, which permits self-hosting but not offering it as a competing service.

ProtoPie: Is there a free version of ProtoPie?

Yes. The free plan includes 2 prototypes, 8 scenes per prototype, and 50MB cloud storage. Perfect for trying the platform.

Source
Restate: How does it compare with Temporal?

Same problem, different shape: one Rust binary with embedded storage instead of a server plus database plus workers, and lower per-step latency.

ProtoPie: What is included in the Pro plan?

Pro plan at $47/month includes unlimited prototypes, unlimited handoff recordings, 5GB team storage, local saving, and team libraries per editor.

Source
Restate: Is there a free tier?

Yes, fifty thousand durable actions a month on Restate Cloud with no card required.

ProtoPie: What add-on products does ProtoPie offer?

Connect Core ($20/month per user), Connect Enterprise and Connect Embedded (custom pricing), and User Testing (custom pricing, annual-only for Pro plan users).
