Looks like we have the same question.

Puck is focused on providing a solution for non technical folk to build on-brand web pages with their team’s existing React components. This enables them to build web pages with guard rails that respect their brand guidelines.

Plasmic is a no-code tool for building websites and applications from scratch. A great solution for a different problem.

Hi! I work on Plasmic. Plasmic's most common use case is actually the same one, letting content editors build pages in your existing website using your React components.

Congrats on this release! We are actually open sourcing Plasmic soon, would love to discuss any possible ways to collaborate.

Oh that's fantastic. I wasn't aware and applaud the decision to go open source.

Happy to discuss/collaborate. I'm @chrisvxd on GH/Twitter, and here's my LinkedIn: https://linkedin.com/in/chrisvilla/
