What was actually said
“I maintain a set of REST microservices (Go and Node.js, in Docker on Linux) and our API regression suite is mostly hand-written Postman collections. Keeping them updated takes too much time, and our mocks for downstream services drift from real behaviour.”

Background and pain
The pain
Manual suites are expensive to maintain and mocks drift from real downstream behaviour: green CI no longer means nothing broke.
A buildable angle
The opening
Record real traffic to auto-generate regression tests with downstream mock snapshots and derived assertions, CI-friendly. Open-source core plus a paid team tier.
How to validate it
- Read the whole thread and note the recurring scenarios — repetition is the density of the need.
- Search existing tools around "api testing / regression" and check which single step they actually cover.
- Put up a one-line landing page, share it back to Stack Exchange, and see whether anyone asks about pricing.
