The short version

  • Only Restate has a free tier, so it costs nothing to try first.
  • Each has a real cost: Koyeb pricing starts at $29/month with additional compute costs; 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: Koyeb covers Serverless containers, Restate covers Durable execution.
  • Prices and features above 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.

Koyeb

  • Pricing starts at $29/month with additional compute costs
  • GPU compute is expensive at $0.75-$2.50 per hour
  • Limited customization for infrastructure configuration

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.

Koyeb: What are Koyeb's subscription plans?

Pro plan is $29/month with $10 included compute, Scale plan is $299/month with $100 included compute and 99.9% SLA, and Enterprise starts at $1,000/month with unlimited users and 99.99% SLA.

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.

Koyeb: How much does GPU compute cost?

GPU pricing is per-second: RTX-A6000 costs $0.75/hour, A100 costs $1.60/hour, H100 costs $2.50/hour, and 8x H100 costs $20.00/hour.

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.

Koyeb: What database options are available?

Koyeb offers serverless Postgres starting at free (0.25 vCPU, 1GB RAM) up to 3XL at $1.28/hour with 8 vCPU and 32GB RAM. Storage costs $0.50/month per GB.
