The AI Cost of JavaScript Frameworks: What Nolan Lawson's Benchmark Tells Us
· 7 min read
"Rewrite it in X, agents are better at X" has become a common argument in frontend teams, and it almost never comes with numbers. Nolan Lawson's The AI cost of JavaScript frameworks (October 28, 2026) is one of the first attempts to measure it. He had the same coding agent build the same app in 12 frameworks, five times each, and tracked what it cost, how long it took, how much code it produced, and how fast the result loaded. This post summarizes the findings, the caveats that matter, and what they mean for the Aliz tech stack.
