How do you govern test data across microservices and teams?

In larger systems, test data isn t just a technical problem anymore, it becomes a governance problem.

Different services, different schemas, different teams.
Some rely on shared fixtures, others on generators, some add an extra abstraction layer (GraphQL, contract mocks, API gateways).

How do you handle:

  • Ownership of test data per service?

  • Keeping schemas in sync with production APIs?

  • Preventing teams from breaking each other s tests via shared data?

TestSeed - Deterministic test data for reliable CI/CD pipelines

TestSeed is an API-first tool for deterministic, schema-driven test data. Instead of random generators or brittle fixtures, TestSeed lets teams define reusable seeds from OpenAPI, GraphQL, or custom schemas and generate identical datasets across local dev and CI/CD. This makes integration test failures reproducible, eliminates flaky tests, and keeps microservice pipelines reliable.

Best developer tools launched on Product Hunt in 2025?

As we're wrapping up 2025, what are the best dev tools launched on Product Hunt this year in your opinion?

Dropping here some of my favorite, most inspiring dev-first product launches, in no particular order:

  • @v0 by Vercel - Runner-up in 2023, the v0 team launched twice this year, introducing v0 for iOS, ranked #1 Product of the Day.

  • @Cursor - The 2024 Product of the Year still hits the charts. This year, they launched 5 times, introduced 2.0, ranked #1 Product of the Day and #1 Product of the Week.

  • @Aikido Security - In the growing context of vibe coding and related security issues, the DevSecOps company is spot on: "Security is an everyone problem." This year, they acquired 2024 Golden Kitty Award nominee @Trag and nailed their first launch: #1 Product of the Day, #1 Developer Tool of the Month. Read on: A look at Aikido's first launch on Product Hunt.

  • @Lingo.dev - The AI localization engine (YC F24) launched on Product Hunt last February and crushed it: #2 Product of the Day, #1 Developer Tool of the Week, #1 Developer Tool of the Month.

  • @Appwrite - Launched Sites, the "open-source Vercel alternative," last May, ranked #1 Product of the Day, #1 Developer Tool of the Week, and #1 Developer Tool of the Month. The perfect Product Hunt launch?

  • @Kilo Code - The open-source AI coding agent founded by GitLab co-founder @sytses blasted it this year: Two launches on Product Hunt, ranked respectfully #5 Product of the Day and #1 Product of the Day, hit 500K+ downloads on VS Code and JetBrains, and recently raised $8M in seed funding. See: How Kilo Code launched on Product Hunt.

  • @Layercode - In the voice AI space, there's @ElevenLabs (2024 Product of the Year in the category, 16 launches in 2025) and new comers. Layercode is one of them. Launched last October, ranked #3 Product of the Day.

  • @Thesys - Launched three times this year, introduced C1, a GenUI API, and ranked #1 Developer Tool of the Week.

  • @Dimension - After months in stealth mode, the proactive AI assistant for engineering teams, among the most beautifully crafted products for developers, went GA, ranked #2 Product of the Day and #3 Developer Tool of the Week. Read on: How Dimension launched on Product Hunt.
