PactFlow vs Signet
Both stand on contract testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Pick PactFlow if your team needs a managed broker for Pact or OpenAPI contract testing, especially when you want pull request checks and automation options. Starter is free for unlimited users but capped at two integrations; Team raises that to 50, and Enterprise offers unlimited integrations with dedicated support and an on-premises option. Look elsewhere if you need GraphQL or SOAP support.

Signet combines contract generation, provider verification and deployment checks for microservice teams. Its hosting choices are self-managed, and teams should account for its per-integration contract requirement.
