Designing and building embedded UIs

24 Aug 2023

At Fintech Devcon 2023, I gave a talk on designing and building embedded UIs, based on my experiences contributing to Stripe Elements and then to Rainforest’s embedded components.

I got some great comments and questions afterwords and wanted to start a broader conversation to bring together engineers and product people working with <iframe>s.


You can download the slides as a pdf. although note that some of the diagrams have animations that won’t work well statically and really need video to do them justice.



I want to repeat what I said in the talk: while I have tried to gather together this information and make it easily available to more people, I am not primarily responsible for having learned or designed most of the things in this talk.

A huge thanks to the people who taught me or learned together with me, especially: Alex, Jenan, Michelle, David, and Tyler. You know who you are. I’m just trying to pay it forward.
