There are two ways to ship a web app with AI today. In 2026, both are already breaking.
The app builders. Lovable, Replit, v0, Bolt, and a dozen more from the last six months. You type a sentence, you get a page, and the first hour feels like magic. Then you ask for a second user on the same document, an external API, or scale past a few hundred sessions. You then enter vibe slop hell. You built a sketch inside someone else's app, and the moment the idea carries weight, you have to leave to finish it somewhere real.
A coding agent on a real stack. The serious path if you actually want to ship a product. Direct an agent to create a webapp, and Claude's usual recommendation is Vercel for frontend, Supabase for database, Clerk for auth, Railway for backend, and Cloudflare for realtime. Before you even touch the product, you're half a day into accounts, keys, and OAuth callbacks, and the agent is burning tokens coordinating various services. Five dashboards. Five bills.
The wiring is not the only problem. There's a bigger one: judgment.
Left to assemble the stack itself, the agent makes choices a senior engineer would never sign off on: auth checks that don't hold, data models that throttle past a few hundred users, shortcuts that become vulnerabilities. The model can code, and it codes fairly well. It just can't reliably tell "runs on my laptop" from "safe in production," and we ask it to make that judgment from scratch every time.
I spent months blaming the model. But the model wasn't the problem. The stack was. None of it was designed for an agent to drive. It was built for humans to assemble by hand, and we gave that to an agent and acted surprised when the seams showed.
So we built the thing the agent should have been importing all along.
DeepSpace is an SDK built for the way code gets written now. One install. Auth, database, realtime, storage, AI, payments, deploy, custom domains, and hundreds of integrations, behind a single import. No second vendor, dashboard, or key. The decisions that used to need a senior team (how state is shared, how identity is verified, what scales and stays secure) are made once, inside the SDK. The agent doesn't reinvent the foundation on every project. It inherits one that already holds.
In our testing, cloning something like Google Docs or Slack runs 5x faster with the SDK than from scratch, and what ships is more scalable and secure. This isn't an exaggeration. The coordination and architecture layer was 80% of the time and the pain. We took it off the agent's plate so it can spend its tokens on your product instead of the plumbing.
And the end result is yours, not a no-code box you rent until you outgrow it. You own the runtime, extend it freely, ship it on your own domain.
This category will consolidate. The only question is around what: builders that produce convincing prototypes, or infrastructure an agent can actually drive to production.
We've made our bet.
