Chrome DevTools is the built-in browser inspector and debugger that ships with Google Chrome, giving testers ground-truth visibility into DOM state, network traffic, device rendering, and runtime behavior. In the context of Agentic Testing and QA — the emerging pattern where AI agents draft, execute, and summarize tests with reduced human supervision — DevTools remains the verification layer that confirms what an agent actually did inside the browser.

AI is now writing more of your code than ever. But the problem is that your test suite was built to catch errors, not to catch the difference between what an AI agent produced and what your original specification actually required. As AI tools accelerate development velocity, the volume of code moving through pipelines is outpacing traditional quality processes.

Quick summary: AI accelerates code creation, but its inherent confidence pushes structural risks downstream, where they surface as costly, release-blocking problems. As code output scales, performance validation that can’t keep pace becomes a headache and a business risk. Agentic performance testing embeds skepticism and performance awareness into the development process before risk can compound. Software development requires specialized expertise for a reason.

Most core banking systems were never designed to move. They were built to run reliably inside controlled environments, with tightly bound processes, batch cycles, and layers of regulatory logic stitched over time. Now, those same systems are expected to support real-time payments, embedded finance, and API-driven ecosystems, often without a fundamental redesign. That mismatch is forcing a shift.

I spoke at AI Engineer Europe last week, and came away with a clearer picture of where the industry actually is right now. My talk was about why AI user experience breaks at the transport layer. But the bigger takeaway wasn't from my own session. It was from watching what the rest of the room was building, and what problems they were running into.

For decades, software engineers have relied heavily on C and C++ to build embedded systems. These legacy languages offer the deep control and speed required for constrained environments, but they reveal gaps in memory management and concurrency. The Rust programming language has emerged as a solution.
