A real production layer for your AI-built app.

If you've shipped a prototype with Lovable, Bolt, or Replit and you're staring at the gap between "it works on my laptop" and real customers can use it — that's what we're building. A team of senior engineers that lives on your repo, a control plane that operates your app while you sleep, and the SDK that handles auth, billing, GDPR, observability, and everything else underneath. Open-source agents, hosted platform.

What we're building

An SDK, a fleet of agents, and a control plane. One platform.

Sulis brings 20+ years of production architecture — auth, billing, observability, the boring-but-critical stuff — together with a fleet of agents that help you use it without becoming an infrastructure engineer.

The SDK
9 domains. 172 operations.
Auth flows, billing, GDPR consent, custom roles & org groups, async compute for long-running jobs (crawling, data processing, model training), workflow orchestration, AI-native observability, secret rotation, custom domains. Production-tested inside the platform.
The Agents
A team of senior engineers on your repo.
A fleet of specialised Claude-based agents — security, codebase quality, production readiness, privacy, observability, cost. They run on every push from Lovable, Bolt, Replit, and the rest. Open-source foundations live today on github.com/sulis-ai/agents (MIT). Production fleet in active build.
The Control Plane
Runs your app while you sleep.
Ambient observability. A background agent self-heals known issues and only wakes you when judgement is needed. The default state is calm.

The agents, in action

They read your code. Tell you what's missing. Fix it for you — with your say-so.

Lovable, Bolt, and Replit sync your project to GitHub. The agents live on the repo and run on every push — reading what was generated, surfacing production gaps in plain English, drafting the fix as a pull request. Want to see the working state in your build tool? An optional side panel (shown below) brings the agents into Lovable. Either way, nothing changes without you reviewing.

Build tool
You Add a payments page with Stripe and user accounts.
AI I've added a /payments route, a Stripe checkout integration, and an /auth flow. The app now stores user emails for receipts and reads JWTs from cookies for authentication.
// api/auth.ts export function authUser(req) { const token = req.cookies.token; // no validation — just trust the token return { userId: token }; } // api/payments.ts export async function handlePayment(req, res) { const user = authUser(req); await stripe.charges.create({ amount: req.body.amount, customer: user.userId, }); // no rate limit, no idempotency, emails stored without consent }
You're in control. Each agent starts as an observer — it watches, suggests, and drafts pull requests for you to review. Nothing merges without you. As you trust an agent, you can graduate it to acting on whole classes of actions without asking. Every action logged. Every action reversible.

After you ship

Wake up to confirmation, not a fire.

Once your app is live, the control plane is your morning check. A background agent watches the system, self-heals known classes of issues, and only escalates when something needs a human. The default state is calm.

The morning after you shipped a new feature. The agent handled two real incidents while you slept — restarted a failing worker and scaled storage proactively. The attention queue is empty because nothing needed a human. That's the product.

Who's building it

I've been building production systems for 20+ years.

I moved from South Africa to the UK with nothing — my first job was stuffing envelopes. Technology got me out, and I've spent the last 20+ years building production systems for enterprises that couldn't afford to break. Sulis is what happens when that experience becomes a platform anyone can call. If you're building something with AI tools and you're stuck on the production side, I'd love to hear about it.
