How does this compare with Flask?

It seems to come with ORM and request validation, metrics, etc. built-in. Flask is fast for getting started but you end up rebuilding most of the things this framework does on your own as your application grows.

It seems like a good middle ground between Flask (minimal and no batteries included) and Django (bloated but very powerful).

I don't see the ORM or metrics in the docs.

After a cursory look at it, this seems like an interesting, modern replacement for Flask. Types-first frameworks are interesting, as they're still very rare right now.

"The molten.contrib package contains various functionality commonly required by APIs in the real world such as configuration files, prometheus metrics, request ids, sessions, SQLAlchemy, templating, websockets and more."

Ah! Missed that, thank you :)

It looks like there's no template rendering so it would seem that Molten:Flask :: Restify:Express in that it is mostly for build an API.

Author here - while molten is API-first, there is built in support for things like sessions[1] and templates[2] for when you need them. The docs could definitely do a better job of highlighting them, though.
