Charlie Cheever posted on X on Nov. 9 (US time) a preview of Exact, a new agent-native app framework written in Rust (about 1,500 likes). He described it as "extremely fast" and built to let you create exactly the experience you want with no compromises.
Cheever claimed Exact is faster on the web than any other fully featured web framework he has found. As evidence he used the Pokédex benchmark proposed by Nolan Lawson in an Oct. 28 post, "The AI cost of JavaScript frameworks." He said Exact is neck and neck with Astro and meaningfully ahead of Next.js and SvelteKit.
The notable part is the cost of AI authoring. Cheever wrote that although Exact is not in the weights of any AI model, agents produced a correct result faster than with Next.js for about the same cost. He conceded that a static site in Astro is still cheaper and faster. UI is written in a new language called Contract, designed from the ground up for AI agents. The framework is a preview and the numbers come from its developer; no independent check has appeared.
“I want to share a preview of something I've been working on called Exact. It's a new Agent Native app framework written in Rust.”
