Why B3

b3-cf-stack is already built and public. The hard part, an opinionated starter people actually use, exists.
Deep Cloudflare knowledge: Workers, KV, Drizzle adapters, PR previews. B3 has shipped the pieces.
Classic open-core motion: the template earns trust, the managed platform earns revenue.

Why now

Cloudflare's platform is maturing fast but the developer experience of wiring it all together is still rough. A batteries-included starter with a managed control plane rides that gap while it is still open.

What it could be

One-click deploy and managed upgrades for apps scaffolded from the starter.
Premium modules: auth, billing, admin, observability, pre-wired for Cloudflare.
A dashboard over Workers, D1, KV, and R2 that the raw Cloudflare console does not give.
Team features: environments, preview management, role-based access.

Open questions before it is real

Does this compete with Cloudflare itself, and does that end well?
Is the starter's usage large enough to convert into paid seats?
What is the wedge versus SST, Alchemy, or Cloudflare's own tooling roadmap?
Managed platforms are heavy to operate. Can two people carry the on-call?

This is a proposal, not a plan. No research pass has run on it yet. To promote it to a full brief with a market read, competitor scan, and a verdict — the way Estate Ops was done — say the word and it moves up the board.
