What growing out of the builder takes
Start from what the builder produced: the interface code, the records behind it, and the list of things the app actually does — sign-ups, uploads, emails, payments. Each behaviour becomes a declared resource: handlers as functions, records keyed into tables, uploads in buckets, and anything scheduled or multi-step as a workflow.
Nothing about that requires a rewrite of the visible app. The screens keep working; what changes is that the machinery behind them is now written down in stack.json, where a person — or an agent, supervised — can change it deliberately.
Building with agents, under approval
The fear teams bring from builder tools is losing the speed. KERNSTACK keeps the speed and adds the checkpoint: an agent drafts the change in a sandbox, the platform shows the plan, and a person approves it. The prompt-to-production leap becomes prompt, draft, review, production.

Why teams switch from Lovable to KERNSTACK
| Dimension | Lovable | KERNSTACK (Software Lifecycle Cloud) |
|---|---|---|
| Starting point | A prompt; the builder generates and hosts the app | A project whose stack.json declares what runs |
| How changes happen | Re-prompt and accept what the builder produces | Agents draft in a sandbox; people approve the plan diff |
| Backend | Hosted plumbing chosen by the builder | Functions, tables, buckets, and workers you declared |
| Background work | Limited to what the generated app wires up | Workers and workflows with human steps, as resources |
| Where it runs | The builder’s hosted platform | Our own bare metal in Europe, one zone per project |
| Bill | Builder subscription and credits | One credit balance metered on actual compute and storage |
Frequently asked questions
No. The generated code is the starting asset; it keeps running where it is until the KERNSTACK project is ready to take traffic. The move is a re-declaration of the backend and a repointing of the interface, not a bonfire.
Your team, with agents doing the drafting. That is the honest trade: you gain an owner’s control — declared data, reviewable changes, European hosting — and you take on an owner’s responsibility, with the platform’s sandboxes and plans keeping changes supervised.
The project meters one credit balance: compute at 0.01 credits per GiB-second, storage at 0.04 credits per GB-hour, egress at 9.00 credits per GiB. An idle project spends no compute credits, which suits the long tail of small apps builders leave behind.
