AI cost of JavaScript frameworks
The gist
Blogger Nolan Lawson had AI agents build the same Pokémon app in 12 JavaScript frameworks, with costs ranging from $2.67 to $4.97.
The test targets framework choices made on hype rather than evidence as agents take over coding.
How it unfolded
- Oct 28, 2026Nolan Lawson publishes "The AI cost of JavaScript frameworks" on Read the Tea Leaves, describing a benchmark in which agents build a Pokémon app with different JavaScript frameworks and meta-frameworks.
- Nov 1, 2026LavX News publishes an article summarizing the benchmark's results across 12 frameworks.
- recentlyEach framework built the same PokéAPI app 5 times with the median taken, except Angular, which failed to create a working app twice and got 3 iterations. Cost per run ranged from $2.67 (Hono+htmx) to $4.97 (Angular).
