Comparison	Perseus	Eleventy
Language The programming language this framework is built in. (Hint: Rust is the fastest!)	Rust	JavaScript/TypeScript
Static generation Whether or not the framework supports pre-rendering pages at build-time.	✅	✅
Server-side rendering Whether or not the framework supports rendering pages dynamically when they're requested.	✅	❌
SSG & SSR in same page Whether or not the framework supports SSG and SSR (see above) in the very same page.	✅	❌
Internationalization Whether or not the framework supports building a multilingual app. Some frameworks support this through plugins.	✅	🟡
Incremental generation Whether or not the framework supports rendering pages on-demand and then caching them for future use.	✅	❌
Revalidation Whether or not the framework supports rebuilding pages that were built at build-time at request-time. Some frameworks can do this by time, or by custom logic. Perseus supports both.	✅	❌
Inbuilt CLI Whether or not the framework has a command-line interface for convenient usage. Some frameworks use third-party CLIs.	✅	✅
Routing support Whether or not the framework supports inbuilt routing. Most frameworks have their own way of doing this if they do support it.	✅	✅
App shell Whether or not this framework has an app shell, which makes switching pages much faster and cleaner.	✅	❌
Easy deployment Whether or not this framework supports easy deployment. Perseus can deploy in one command.	✅	✅
Static exporting Whether or not this framework can operate without a server, as a series of purely static files.	✅	✅
Homepage Lighthouse Score (Desktop) The Lighthouse score out of 100 for desktop (higher is better). These are collected from Google's PageSpeed Insights tool. These are for the framework's website, and may not reflect the performance of all sites made with the framework.	💯	💯

Perseus vs Eleventy

Eleventy is an extremely capable static site generator that creates websites that are usually as performant as Perseus ones, though it lacks the state platform necessary for app development. With a host of integrations out of the box, Eleventy is an excellent choice for small websites, though Perseus' app shell and state platform make it outperform Eleventy at runtime, while enabling the development of more advanced apps that take advantage of features like request-time state generation, and incremental generation.

Perseus vs Sycamore

Perseus is a framework that uses Sycamore to write views (the things users see), so there's not much point in comparing the two as competitors. However, Sycamore can be used without Perseus, which works perfectly well, though you'll miss out on features like inbuilt internationalization, static generation (though you could build this yourself), and incremental generation. If you want to build just a bit of your site with Rust, Sycamore is the perfect tool, Perseus is a full framework designed for building entire websites.
