## Key points

- Hono with htmx had the lowest median cost at $2.67.
- Astro built and tested the app fastest, in 8.2 minutes.
- Server-centric tools generally suited the AI agent better.

## Summary

Nolan Lawson benchmarked 12 JavaScript frameworks by asking Claude Code to build the same Pokémon app with data from PokéAPI. The results suggest AI coding agents can work more efficiently with server-centric frameworks than with client-heavy single-page apps, especially when tools favour established conventions, stable APIs and concise code.

Lawson ran five sandbox trials per framework, then checked the apps with automated accessibility tests and Google Lighthouse. Hono with htmx had the lowest median build cost at $2.67, followed by Astro at $2.76; Astro also had the fastest median build-and-test time, at 8.2 minutes. Nuxt was the least costly option among the SPA-like approaches at $2.82 and used the fewest tokens, 3.85 million.
