Validate Spring Boot Upgrades with Traffic Replay
Spring Boot upgrades silently change JSON contracts and autoconfiguration. Use traffic replay to catch every regression before production.

The AI Code Explosion: Why Your Mocking Strategy is Breaking Down
AI-generated code breaks traditional mocking. Here's how BYOC capture and replay with proxymock keeps verification grounded in real production traffic.
Your AI agent is fixing the wrong service
I tested 100 bugs across 240 microservices the model has never seen. Alert only: 51% pass rate, wrong service 34% of the time. Traffic captures: 77%.
WireMock alternatives: pick the one that fits your problem
A 2026 take on WireMock alternatives. Keep WireMock for what it's good at; add Microcks (now CNCF Incubating) or proxymock for the gaps. The honest map.
Replay Real Customer API Sessions as Datadog Synthetics Tests
Export recorded proxymock traffic to Datadog Synthetics in one command. Auth headers redacted, global variables created. No scripting, no flaky journeys.
Replace API Synthetics with Traffic Replay
UI synthetics only tell you something is broken. Traffic replay per microservice isolates failures before any human walks up. Zero scripts required.
Dark Code: The AI-Generated Software Nobody Understands
Dark code is software no human has written, read, or reviewed. As AI tools accelerate, the gap between shipped code and understood code is widening fast.
From Datadog to CI Tests: Catch Regressions Before Deploy
Learn a practical workflow to convert Datadog metrics, traces, and incidents into CI tests that catch regressions before deploy.
AI Coding Agents Break What Works
AI agents silently modify working systems to force changes through. Three real patterns and the guardrails that catch them.
