The short version

  • Only Restate has a free tier, so it costs nothing to try first.
  • Each has a real cost: MetricStream implementation typically costs one and a half to two and a half times the first year licence, so a one million dollar licence carries a one and a half to two and a half million dollar rollout that rarely appears in the initial business case.; 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.
  • They diverge on capability: MetricStream covers Enterprise and operational risk, Restate covers Durable execution.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

MetricStream

  • A small team that wants durable workflows without operating a Temporal cluster and its databasenot MetricStream

Where each one falls short

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

MetricStream

  • Implementation typically costs one and a half to two and a half times the first year licence, so a one million dollar licence carries a one and a half to two and a half million dollar rollout that rarely appears in the initial business case.
  • Full deployment takes six to eighteen months, during which the organisation runs old and new processes in parallel and the promised efficiency gain is negative.
  • Per-user pricing in the low thousands per year per seat discourages giving access to the first line of defence, which is precisely where risk data originates, so many deployments end up with data still arriving by spreadsheet.
  • Configuration flexibility comes at the price of specialist skills, and organisations become dependent on MetricStream partners or a small internal team, making later changes slow and expensive.
  • The interface and workflow feel enterprise-heavy next to modern compliance tools, and infrequent business users find it hard, which suppresses the participation the platform is meant to enable.

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.

Does MetricStream or Restate run on more platforms?
MetricStream runs on Web. Restate runs on Linux, macOS, Web.
Can I use Restate for free?
Yes. Restate has a free tier, so you can try it without paying. MetricStream starts at On request.
What is MetricStream best used for?
MetricStream is most often used for a multinational bank mapping one control set against obligations from several regulators and needing to evidence the mapping to examiners, an insurer consolidating separate risk, audit and vendor systems that currently produce contradictory numbers to the board, a pharmaceutical company that must track regulatory change across jurisdictions and show what each change affected, an organisation whose three lines of defence must share one risk taxonomy rather than three overlapping spreadsheets. Of those, a multinational bank mapping one control set against obligations from several regulators and needing to evidence the mapping to examiners and an insurer consolidating separate risk, audit and vendor systems that currently produce contradictory numbers to the board are not what Restate is typically brought in for.

Answered from the vendors’ own pages

MetricStream: What does MetricStream cost?

It is quoted. Market data suggests roughly 75,000 to 150,000 US dollars a year for small enterprise deployments, 250,000 to 500,000 for medium and 750,000 upwards for large.

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.

MetricStream: How long is implementation?

Six to eighteen months for a full platform deployment, and the services cost usually exceeds the first year licence.

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.

MetricStream: Is it right for a mid-market company?

Usually not. Its depth suits organisations with several regulators and formal three lines of defence structures.

Restate: Is there a free tier?

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

MetricStream: Does it replace SOC 2 automation tools?

It can cover the framework, but it is not designed for the automated evidence collection those tools do cheaply.

Restate: Which languages are supported?

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