Remix launched as "Figma, but on your production app."

#9 on Product Hunt with 94 upvotes for editing and testing variants directly against the running production app. It's config-over-code applied to design tooling: source of truth moves from a separate design file that must be handed off and reimplemented to the deployed app itself. The category it erodes isn't Figma's editor, it's the design-to-code handoff and the A/B testing SaaS stacked on top. Single-source launch, but as someone who spent 20 years on the design side of that handoff, this is the right thing to attack.
