Tried out the new native debugging proxy @proxyman_app, and it’s awesomely simple and just works - I love it 👍🏼. Glad to see it works with Websockets too so works with @ablyrealtime.

DeLynn Berry

@delynn

I use Dash ( @kapeli ) almost every day. I find Paw ( @luckymarmot ) indispensable when dealing with APIs. I recently discovered Proxyman ( @proxyman_app ) and I’m glad I’ll never need to use Charles ever again.

Guillermo Rauch

@rauchg

On 2️⃣, I highly recommend http://proxyman.io – you'd be surprised how much you can learn about any system by watching what it does over the network

Wes Bos

@wesbos

Proxyman is such a cool app. You can view http/ws requests from any app on your computer, and install an SSL proxy cert so you can see requests/responses that apps on your computer are making.
I've used many - wireshark, charles, etc - and this is the best one i've used.

Shai Mishali

@freak4pc

Have to say @proxyman_app is an absolutely phenomenal tool. I can't imagine using Charles with a native macOS app that works so well. One thing I'm really missing is the ability to run diffs between requests to the same endpoint, that would be such a valuable feature.

Felix Krause

@KrauseFx

proxyman.app a new app to intercept network traffic on your Mac, a beautiful, native Mac app. Still a huge fan of Charles web proxy, but this one just looks so nice @proxyman_app

Officially switching to @proxyman_app after 10 years of using Charles! Much better interface, app performance, and also shows what process is making a particular web request!

Donny Wals 👾

@DonnyWals

Started using @proxyman_app instead of Charles recently and I’m enjoying it more and more 😁 it basically does everything Charles does, except slightly nicer and more convenient. Especially the way it installs certs on the simulator for proxying 👍🏼

Dave DeLong

@davedelong

Hey @luckymarmot … please acquire and integrate @proxyman_app 🙏 #OneAppToRuleThemAll

Daniel Jalkut

@danielpunkass

I've just discovered @proxyman_app and it looks like a pretty great Mac-only alternative to Charles Proxy. Super streamlined UI that gets right to the heart of what most of us want: to see the request and response being made from a specific app.
