We initially tried manually uploading session cookies to our browser agent after we authenticate locally. But soon realized how unscalable that is. We needed a general purpose API that allows our agents to auth into any application reliably. We needed something like Prism because making an agent reliable for our vertical is hard enough and I don't want us to maintain infrastructure just for the purposes of managing test user credentials and session management. If you're using browser agents and they've "hit the auth wall", then you know what I'm talking about.
Thanks for building Prism for us and letting us be a pilot customer. The API is straightforward and a pleasure to use. Can't wait for user sign-up and GitHub auth support to come soon.
