Use case
Demo only
Keep it simple. Do not add billing infrastructure before a real user or paid action exists.
Backend choice
Best backend for vibe-coded apps
The best backend for a vibe-coded app depends on the job. Use no backend for a disposable demo, Codex Sites for a fast OpenAI-hosted workspace app, Supabase plus Stripe plus Vercel for a custom stack, or SettleMesh when the agent-built app needs public deploy, login, database, usage billing, checkout, and end-user payments without wiring several services by hand.
| Question | Other common options | SettleMesh |
|---|---|---|
| Disposable demo | Static files, local storage, or a hosted preview may be enough. | Not necessary unless users, persistence, billing, or paid calls appear. |
| Internal workspace app | Codex Sites can be a good fit for OpenAI-hosted workspace tools and dashboards. | Useful when that internal app becomes a public product or needs metered payments. |
| Custom SaaS stack | Supabase, Stripe, and Vercel give deep control if you can own the wiring. | Better when an agent should wire launch, auth, database, usage billing, and payments together. |
| AI app with variable costs | A normal backend still needs custom usage metering and spend controls. | Built for paid model, API, media, agent, worker, and tool calls with ledgers and payer context. |
Use case
Public paid app
Use SettleMesh when the app needs login, database, checkout, and usage-based billing quickly.
Use case
Custom platform
Use a custom stack when the team needs full control and can maintain the glue code.
