Ask HN: What's your 2025 "quality stack"?
Feels like we’re all shipping faster, but the old “just write more tests” advice isn’t keeping up.
Teams are smaller, release cycles are tighter, and AI is sneaking into a lot of workflows.
I’m curious what people here are actually relying on these days to keep things from breaking:
- What layers are in your stack? (types/linters, unit, contract, integration, E2E, monitoring, flags, SLOs, etc.)
- Is AI playing a real role yet for you? test gen, self-healing, triage, anomaly detection?
- Anything you dropped recently because it wasn’t worth the effort? (flaky UI tests, snapshot tests, staging envs…)
- For smaller teams, do you still bother with classic QA, or do you lean more on flags/observability/canaries?
- Anyone tried managed or AI-assisted QA instead of DIY? Curious if it actually worked, esp. around trust/cost/lock-in.
- How do you measure “confidence to release” beyond code coverage?
Would love to hear quick snapshots like: - team size / release cadence
- stack (web, mobile, regulated or not)
- pre-merge checks
- post-deploy safeguards
- tools you kept vs abandoned
- biggest source of flakiness right now
- what you’d do differently if starting today
Looking for real, on-the-ground stories from folks shipping in 2025. What’s working for you?
