TestSeed
TestSeed is a SaaS platform for deterministic, schema-driven test data.It eliminates flaky tests caused by random or drifting data by providing a reproducible data baseline across local development and CI/CD pipelines.Unlike random data generators or database seeding approaches, TestSeed guarantees that the same seed version always produces the same dataset (given the same parameters). This makes CI failures reproducible instead of guesswork.TestSeed acts as a single source of truth for test data in API-first and microservice architectures.Key FeaturesDeterministic & Reproducible DataThe same seed version always produces the same data, ensuring stable and debuggable test results across runs.OpenAPI, Swagger & GraphQL SyncExisting API specifications can be imported and used as the basis for test data. No manual mock rewriting required.Schema-First Entity ModelingEntities can be selected from a predefined pool, composed, or customized using a schema-first UI. Supports constraints and controlled edge cases.API-First IntegrationTestSeed integrates as an API-driven data layer. CI/CD pipelines load an API key and seed ID to fetch deterministic test data on demand.Immutable Seed VersionsStructural changes create a new seed version with clear diffs. Older versions remain reproducible for debugging and CI re-runs.100% Synthetic DataAll generated data is synthetic and contains no PII, supporting security and compliance requirements.Use CasesTestSeed is designed for teams testing API-first and microservice-based systems.It allows services such as an orders-api or auth-service to consume deterministic test data without relying on shared databases or production data copies. Multiple services can independently use the same Seed-ID, ensuring consistent users, orders, or states without synchronization.Teams use TestSeed to:test APIs in isolationgenerate valid, invalid, or boundary-case datareplace fragile Faker scriptsreplay failing CI builds with the exact same datasetThis results in stateless CI/CD pipelines and significantly reduced debugging time.Pricing InformationTestSeed follows a freemium model.Solo Dev (Free)500 generations per month, suitable for schema exploration and local testing.Team Pipeline ($25/month)10,000 generations per month, including features like Smart Import and GraphQL support.Enterprise ControlCustom pricing for unlimited generations and self-hosted or dedicated infrastructure.User Experience and SupportTestSeed provides a schema-first UI for defining and managing entities.Getting started typically involves defining or importing a schema, assigning a Seed-ID, and calling the API from tests or CI.Comprehensive documentation is available. Paid plans include prioritized or dedicated support.Technical DetailsTestSeed is not a random data generator.It is deterministic test data infrastructure designed for CI/CD and automated testing.It integrates via HTTP and generates data based on:schema definitionsexplicit constraintsdeterministic seeds and versionsThis ensures reproducibility across environments without shared databases or stateful setup.Pros and ConsProsEliminates flaky tests caused by data driftReproducible results across local dev and CI/CDStateless pipelines without test databases or SQL dumpsStrong security through fully synthetic dataSupports OpenAPI, Swagger, and GraphQLClean, API-first integration into existing workflowsConsNot designed to simulate complex business logic or financial calculationsRequires an initial understanding of schemas or existing API contractsFree and lower-tier plans have generation limitsConclusionTestSeed focuses on one core problem: reliable test data for automated tests.By combining deterministic seeds, schema-driven data, and API-first integration, it helps teams stabilize CI/CD pipelines, reduce debugging time, and test modern distributed systems with confidence.If flaky tests are slowing down your pipeline because test data keeps changing, TestSeed provides a deterministic baseline you can finally trust.
