All starting points

Build a small web app.

Try one working interaction, with a clear path to previewing and keeping control of the code.

What does a useful result look like?

How would you like to work?
What matters for this first build?

Open questions will travel with your prompt. Nothing is assumed on your behalf.

Two ways into this work.

Keep the wider workflow in view as you decide.

From idea to preview

ReplitBrowser app builder

Agent writes code, sets up infrastructure, and tests the result from a plain-language description — no coding knowledge required.

LovableBrowser app builder

One credit balance covers building your app, chatting with Lovable, hosting your app and running its built-in backend (Cloud), and powering AI features in deployed apps.

Keeping control

ReplitBrowser app builder

Agent creates checkpoints as it works so users can roll back to any previous state, and Plan mode lets users review and approve a task list before any code is written.

LovableBrowser app builder

Workspace owners and admins on all paid plans can cap credits per member, project, or the whole workspace, and set alerts when usage or balance crosses a threshold, via Workspace settings → Usage limits & alerts.

Ongoing cost

ReplitBrowser app builder

Free Mode is no-cost everyday Agent work within a plan's allowance (Core and Pro allowances reset every five hours with weekly limits); Power and Max are paid tiers requiring confirmation before each paid action.

LovableBrowser app builder

Credit top-ups are available on Pro and Business plans only: Pro at $0.30 per credit ($15 per 50 credits) and Business at $0.60 per credit ($30 per 50 credits), billed as one-time payments through Stripe and valid for 12 months.

Latest source check: 2026-10-15. These are product offerings, not individual model benchmarks. Plans and availability can change.

Models to evaluate now

Candidates reflect current provider identities and documented capability coverage. A newer release is not evidence of better output quality.

Model and API access can differ from the models available in your chosen app.

Provider coverage and freshness

Source checks and verification rotate within the collection budget. A failed check does not make an old record current.

We’ll help clear the way.

Take the prompt and keep building. If you hit a roadblock, we can help with the architecture, integrations, or an AI-built app that needs experienced hands.
