Apollo Studio vs Assertible

Apollo Studio is the interface for Apollo GraphOS, a platform for managing a supergraph and coordinating GraphQL development. Studio Explorer lets developers create, run, and share GraphQL operations, with query linting and autocomplete. GraphOS maintains a central registry of schemas and metadata, generates changelogs, and visualizes graphs. Teams can review proposed schema changes asynchronously and validate them against past requests from registered clients to check for breaking changes. Composition, validation, and approvals can connect to CI/CD pipelines. Access controls include granular roles and filtered graph variants for specific clients or partners. Studio tracks usage by field, client, and operation, showing trends, request volume, rates, errors, and service traces; OpenTelemetry support can send metrics to a chosen APM tool. Rover CLI supports schema publishing, CI checks, and local supergraph testing, while the Platform API enables custom automation. GraphOS supports any GraphQL API, including Federation and Connectors. Free costs nothing, supports up to three developers, and retains checks and insights data for one day. Developer starts at $5 a month, based on $5 per million requests.

Assertible tests and monitors APIs, websites, and other HTTP services for uptime, availability, and correct behavior. Users create HTTP assertions, inspect request details, and review assertion results. The service can run smoke tests automatically after deployments to staging or production environments. API tests can be imported and synchronized with OpenAPI or Swagger specifications and Postman collections. Integrations listed in its documentation include GitHub deployments and status checks, Slack, PagerDuty, and Zapier. Monitoring schedules range from once per minute to once per day, with shorter intervals available on paid plans. Plans limit services, tests per service, retained results, team members, and schedule frequency rather than monthly request counts. The Personal plan costs nothing and includes two web services, 10 tests per service, 1,000 results, one to two members, and Standard monitoring with two monitors. Paid plans are Standard at $25 a month, Startup at $50 a month, and Business at $100 a month; each includes a one-month trial.
