I feel like the quickest I've ever moved and most innovative stuff I've ever done comes from doing it the "hacky" way. At our latest setup we're just relying on Framer (framer.com) to build all of our UI components using a free drawing canvas.

Then for more customization we have a setup where devs can just spin up a CodeSandbox link in the browser that imports the Framer component to add more interactivity (like custom hooks etc). Everything is deployed via CodeSandbox.

Devs/Designers/Anybody else just use CodeSandbox links, no editors. People responsible for content use these links to edit .json files inside CodeSandbox repository to quickly add/edit things. New images can be uploaded via drag & drop in and when saving the file it becomes part of the git repo. No CMS needed.

We have a bunch of lock-ins with this setup (like if Framer/CodeSandbox goes down we're f**ed) but I feel like going with anything else there will always be lock-in (AWS, Vercel, some open-source project which is now dead and nobody can maintain anymore).

It's amazingly fast to work this way & we love it.
