What is Massvai?
Massvai is an AI full-stack Next.js app builder that turns prompts into production apps. Describe the product, screens and data you want in plain language, and Massvai scaffolds the frontend, backend and database, then keeps everything in sync as you iterate. Key features: prompt-to-app generation for full-stack Next.js projects; live preview while you build; Supabase authentication, database and storage wired in automatically; GitHub sync so every iteration lands in your own repository; one-click deployment to Vercel; code export at any time with no lock-in. It is built for solo builders, indie hackers, designers and small teams who want to validate ideas quickly: SaaS dashboards, internal admin tools, storefronts and landing pages connected to a real backend. Freemium: start free and upgrade when you need more capacity.

Brandon frames paywall view rate as the primary traffic metric to optimize — more eyeballs on the paywall multiplies the impact of every subsequent conversion experiment.
Gruber had a good line — the last thing you want to do if you're a sports team in a high-stakes sporting event is piss off the refs. That's what Apple's doing. They're just inviting more regulation. South Korea is already threatening to fine them. They're squandering developer goodwill.
Apple is pissing off the refs in a game it's already winning
David's read on Apple's strategic blunder. By choosing maximum hostility in DMA compliance, Apple signals to every other regulator in the world that they won't cooperate — which guarantees more aggressive future regulation in other jurisdictions and slowly erodes the developer goodwill that built the platform.
There's a play for whatever you're stuck on.
