Show HN: Robyn – “Batman Inspired” Python Web Framework Built with Rust

Can someone explain how it works under the hood. A Rust server for python obviously needs to still run the python interpreter. Is it running many instances to get around the GIL, and doing the request management / reverse proxy / runtime management in rust?

I'm confused, in the example application I see all these async endpoints interacting with the database, but the function bodies are entirely sync. Wouldn't this block the event loop?

It looks like a nice design! I&#x27;d love to hear a bit more about what it offers over Django&#x2F;Flask&#x2F;FastAPI though!<p>The examples look very similar to Fast API and the requests per second comparisons make Robyn look very speedy![0]<p>I&#x27;m sure the developer has more of a vision than just &quot;faster fast api&quot; though - would love to hear more!<p>[0] <a href="https:&#x2F;&#x2F;github.com&#x2F;sparckles&#x2F;robyn">https:&#x2F;&#x2F;github.com&#x2F;sparckles&#x2F;robyn</a>

It having types makes me accept the Python bit. I&#x27;d still rather go for something in golang though, hard to beat it for web servers.

Why do all those micro framework copy the worst aspects of flask?<p>The global request object, the bad integration with sqlalchemy, the strong coupling with an application object that forced the indirection of blueprints...<p>If you start again from scratch, forcing people to migrate their stack and therefor leave their ecosystem behind, at least fix the glaring API problems.

By looking at the “File Upload” example: <a href="https:&#x2F;&#x2F;robyn.tech&#x2F;documentation&#x2F;en&#x2F;api_reference&#x2F;file-uploads" rel="nofollow">https:&#x2F;&#x2F;robyn.tech&#x2F;documentation&#x2F;en&#x2F;api_reference&#x2F;file-uploa...</a>. Robyn is subject to DoS. While it may be fast but it seems poorly designed. This day and age should use a &quot;reader&quot; concept like Go.

which part of this framework is Batman inspired?

If you hate Python so much you need to replace the linters, package managers, and now Web frameworks with Rust, why not just go all the way and write everything in Rust?

What is Batman? My Google skills are failing

The biggest differentiator between Robyn and frameworks like FastAPI or Sanic seems to be the Rust runtime. But is Python&#x27;s async actually the bottleneck that Rust is solving here?

Ugh we already have BATMAN and ROBIN as meshnet. Can&#x27;t you go with... sea man or some other thing that&#x27;s not taken?
