Petri, a drop-in Postgres image with a Golang proxy.
Technical Positioning
A solution for parallelizing database-dependent tests by forking a fresh database instance per connection, eliminating in-band test runs and DB mocking issues.
SaaS Insight & Market Implications
Database-dependent integration tests are a notorious bottleneck in modern software development, often leading to slow, flaky, and non-parallelizable test suites. Petri directly addresses this critical developer pain point by providing a mechanism to isolate database states for each test connection. By leveraging a drop-in Postgres image and a Golang proxy to fork databases on demand, it enables true parallelization and eliminates the need for complex, often unreliable, DB mocking strategies. This innovation significantly improves CI/CD efficiency, reduces test execution times, and enhances test reliability. For B2B SaaS, this represents a clear demand for specialized tooling that optimizes developer workflows, particularly in environments with microservices and complex data dependencies, driving faster release cycles and higher code quality.

Show HN: Petri – Drop-in Postgres image that forks a DB per test
Rolling it out at work to parallelize 4,257 tests across 5 services. It fixes our tests running in band and DB mocking in API tests.It's a drop-in Postgres image, with a Golang proxy. :5432 is passthrough, :5433 forks the DB per conn (CREATE DATABASE … TEMPLATE …, dropped on disconnect).If you use it, let me know what you like or don't like, so I can make it better. Cheers!
