One prompt to production
An AI builder plans the app, constructs it in a sandbox, shows a live preview, and publishes to a public URL — hosting, database, and sign-in included.

From one prompt to a live application — in minutes.
Most great software ideas die in the backlog. LACE App Builder removes the bottleneck: describe the application you want, and LACE designs it, builds it in a safe sandbox, and deploys it as real, running software at a real web address.
Real applications, not demos
Secure authentication, role management, structured data with an admin panel, versioned releases, gradual rollouts, one-click rollback.
Monetize from day one
Built-in subscription and billing infrastructure — launch, price, and sell on the same platform.
Every app can talk
Applications ship with a built-in AI assistant wired to the app's own data and tools. Every product you launch is an AI product.
Remix and reuse
See an app you like? Remix it into your own editable copy in seconds. Templates compound — your hundredth app is dramatically faster than your first.
A professional lane for developers
A Git repository seeded with a working app and the SDK wired in. Open it in the editor and coding agent you already use, commit, and LACE builds, verifies, and releases it. See the developer lane →
In practice
“I described an inventory tracker in the Studio. Fifteen minutes later I opened a live URL, added our first records, and sent the link to my team.” That is the acceptance bar the App Builder is engineered — and tested — against.
App Builder · SaaS
Not just an app. A business.
Most builders stop at working software and leave you the hard part: the plan customers subscribe to, the checkout that takes their money, the domain, the certificates, the entity, the bank account. LACE ships that with the app.
Describe the product, price it, publish it. The first subscription can arrive the same afternoon.
Talk to us about launching →Billing
Plans, subscriptions, checkout
Tiers, trials, seats, and metered usage. Checkout, invoices, retries, and tax handling come with the platform — not with three vendors and a webhook you maintain.
Accounts
Sign-in, orgs, and roles
Email and SSO/OIDC sign-in, organization accounts, per-role permissions. Enforced by the runtime at every request, not by instructions in a prompt.
Address
Your domain, your certificates
Publish to a domain you own. Certificates are issued and renewed for you, and the app answers on it from the first release.
Capacity
Hosting that follows demand
Each application runs as its own isolated sidecar runtime. Capacity follows traffic; you never provision a server to launch a price change.
Releases
Versioned, gradual, reversible
Every deploy is a numbered release. Roll it out gradually, watch it, and roll back in one click — with the previous version still intact.
Company
Entity and payouts
Form the company, connect the account that receives the money, and take payouts on a schedule you set. The business exists, not just the software.
App Builder · lace-app-sdk
Build it where you already build.
The App Builder is one way in. The other is the one you already know: LACE hands you a Git repository, seeded with a working application, the SDK wired in, and agent instructions that tell your coding agent how this platform works — so it spends its context on your product instead of relearning ours. Open it in whatever you use. Commit. LACE takes it from there.

- Vim + a terminal
It is a Git repository. Anything that can open one, works.
Seeded, not scaffolded from scratch
The repository arrives with the manifest, a running app, example data collections and tools, tests, and the instruction files your agent reads first. Nothing to wire up before the first useful commit.
One import surface, versioned
Apps import lace_app_sdk and nothing deeper. It is a facade
over the live platform contracts — never a fork — so what you write
locally is what runs in production, and a breaking symbol is a major
version with a deprecation window.

Under the hood
A build pipeline you could show your auditors.
An audited lifecycle
Intent → architect session → scaffold → validate → proof lanes → seal and package → publish. Every stage recorded, every release versioned.
Isolated sidecars
Published apps run as their own sidecar runtimes. Core never imports app code; apps never bypass tenant or policy checks.
The public SDK
Generated and hand-written apps target the same lace-app-sdk contracts — so tenancy, policy, data governance, and audit come for free.
FAQ
What enterprise teams ask.
What does LACE App Builder create?+
It creates real web applications with a user interface, structured data, sign-in, permissions, hosting, versioned releases, and rollback. Applications can also include governed agents and AI assistants.
How does LACE make AI-generated applications safer?+
Generated code runs in an isolated sandbox and reaches identity, data, policy, limits, and audit only through governed SDK capabilities. It does not receive raw database credentials or unrestricted infrastructure access.
Can professional developers work on a LACE application?+
Yes. Generated and hand-written applications target the same public lace-app-sdk contracts. Developers can work locally, use version control, review changes, and deploy through the same release pipeline.
Can I build a LACE application in my own editor or coding agent?+
Yes. Developer access is a Git repository seeded with a working application, the lace-app-sdk wired in, and agent instructions describing the platform. Work in Claude Code, Codex, Cursor, VS Code, JetBrains, or a plain terminal — anything that opens a Git repository. On commit, LACE builds the app in isolation, runs contract, policy, and your own tests, then publishes a versioned release you can roll back.
Can I sell subscriptions to an application built on LACE?+
Yes. Applications can ship with subscription plans, checkout, invoicing, and metered usage, published on a domain you own with certificates issued and renewed for you. Hosting scales with the application, and every release is versioned and reversible.
Can applications run in a private or air-gapped environment?+
Yes. LACE supports managed cloud, private cloud, on-premises, and fully air-gapped deployment. The application inherits the same identity, policy, data governance, and audit controls in each footprint.
MCP Server
Works where you work.
The whole platform is an MCP server. Connect it once, and the AI tools your team already lives in can search your knowledge, ask the graph, and put governed agents to work — same permissions, same citations, same audit trail, wherever the question is asked.
