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 Features

Deterministic & Reproducible Data
The same seed version always produces the same data, ensuring stable and debuggable test results across runs.

OpenAPI, Swagger & GraphQL Sync
Existing API specifications can be imported and used as the basis for test data. No manual mock rewriting required.

Schema-First Entity Modeling
Entities can be selected from a predefined pool, composed, or customized using a schema-first UI. Supports constraints and controlled edge cases.

API-First Integration
TestSeed 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 Versions
Structural changes create a new seed version with clear diffs. Older versions remain reproducible for debugging and CI re-runs.

100% Synthetic Data
All generated data is synthetic and contains no PII, supporting security and compliance requirements.

Use Cases

TestSeed 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 isolation

• generate valid, invalid, or boundary-case data

• replace fragile Faker scripts

• replay failing CI builds with the exact same dataset

This results in stateless CI/CD pipelines and significantly reduced debugging time.

Pricing Information

TestSeed 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 Control
  Custom pricing for unlimited generations and self-hosted or dedicated infrastructure.

User Experience and Support

TestSeed 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 Details

TestSeed 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 definitions

• explicit constraints

• deterministic seeds and versions

This ensures reproducibility across environments without shared databases or stateful setup.

Pros and Cons

Pros

• Eliminates flaky tests caused by data drift

• Reproducible results across local dev and CI/CD

• Stateless pipelines without test databases or SQL dumps

• Strong security through fully synthetic data

• Supports OpenAPI, Swagger, and GraphQL

• Clean, API-first integration into existing workflows

Cons

• Not designed to simulate complex business logic or financial calculations

• Requires an initial understanding of schemas or existing API contracts

• Free and lower-tier plans have generation limits

Conclusion

TestSeed 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.
