The short version

  • Free plans on both; paid from $1.5/mo and $300/mo.
  • Only Materialize lists real-time Data Ingestion; only Restate lists durable execution.
  • Where Materialize falls short: community tier limited to 24GB memory, restricting production deployments.
  • Prices and features on this page were last checked on 31 August 2026.

Where each one falls short

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

Materialize

  • Community tier limited to 24GB memory, restricting production deployments
  • Compute credit pricing requires predicting usage patterns
  • Learning SQL transformation models adds complexity vs pre-built solutions
  • Self-managed deployments require operational expertise

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

Materialize: What is included in the free Community tier?

The Community tier is free forever for deployments up to 24GB memory and 48GB disk with community Slack support and self-service setup.

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.

Materialize: What are the storage and networking costs?

Cloud plans charge for storage at $0.00004110-$0.00003151 per GB/hour and networking at $0.12-$0.09 per GB, with lower rates on the Capacity plan.

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.

Materialize: How do I get started with Materialize?

Start with the free Community tier for development and non-production use, then migrate to Cloud On-Demand or Cloud Capacity when you need production scale.

Source
Restate: Is there a free tier?

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

Restate: Which languages are supported?

TypeScript, Java, Kotlin, Go, Python and Rust.
