For Bolt builders
Bolt built your MVP in a weekend.
Production is a different machine.
Bolt is genuinely great at what it does: an idea becomes a working app in your browser, sometimes in hours. But the moment real customers show up, you need machinery Bolt never built — background jobs, payment webhooks, rate limits, monitoring. That's the boring engine room of a SaaS, and it's the part that decides whether you can take people's money. useDeploy is that engine room, finished and tested, waiting for your product to sit on top.
Why the MVP feeling doesn't survive contact with customers
Bolt runs your app in WebContainers — a brilliant trick that boots a full development environment inside a browser tab. It's perfect for building fast and demoing faster. But production isn't a browser tab. Real customers mean payment webhooks arriving while you sleep, receipts that must send even if the server hiccups, and the same subscription event showing up twice without anyone being double-charged. Community verdicts are blunt: “These vibe coding apps are very good for MVP and that's it. If you want a serious production app, then these tools can't help” (rednuggets on indiehackers.com) — and a securityscanner.dev audit found 15% of Bolt apps shipping with hardcoded API keys exposed. None of that means Bolt failed you. It means the MVP stage ended.
The machinery a paying-customer app runs on
Background jobs with retries
Sending receipts, syncing data, cleaning up expired invites — work that runs on a schedule and retries when it fails, instead of silently not happening.
Webhooks that can't double-charge
Stripe and MercadoPago resend events. Your app has to recognize a repeat delivery and ignore it, every single time.
Rate limiting
One buggy script or one bad actor shouldn't be able to hammer your signup endpoint until the app falls over.
Monitoring you can actually read
Structured logs and error alerts, so “the app is slow” becomes a line you can look up instead of a mystery.
Emails customers expect
Invites, password resets, magic links — delivered reliably, not only when the original request happens to succeed.
Watch a crashed webhook finish anyway
In useDeploy, side effects run through a durable outbox: when a payment webhook arrives, the work it triggers is written down first, then executed. If the server crashes halfway, nothing is lost — the outbox picks the task back up and retries until it's done. This is the difference between “it usually works” and “it works.”
1 [outbox] event billing.subscription.activated queued
2 [outbox] handler send-welcome-email failed (SMTP timeout)
3 [outbox] retry 1/5 in 30s…
4 [outbox] handler send-welcome-email ✓ delivered
5 [outbox] event marked processed
The engine room, already assembled
Payments, three providers deep
One billing interface covers Stripe, MercadoPago subscriptions, and Polar — and duplicate webhook deliveries are filtered by order ID before they can touch your data.
BullMQ job queues
Scheduled and retried background work, ready for receipts, syncs, and cleanups.
Tiered rate limiting
Separate limits for reads, writes, and auth attempts — backed by Redis in production, plain memory while you develop.
Observability that stays out of the way
Structured logs, error tracking, and a metrics endpoint — all off by default, each one a single env var away.
Real multi-user accounts
Organizations with roles, invitations, and API keys, with cross-organization access blocked at the database layer.
A CI gate that walks the money path
An end-to-end browser test registers, creates a team, invites, and subscribes on every change — with 450+ tests underneath it.
Your migration path from Bolt
Bolt's honest superpower is that it hands you real code — download your project and it's a standard web app, no proprietary runtime to escape. That makes the move mechanical rather than heroic. Keep your UI and product logic; retire the improvised backend parts — ad-hoc API calls, half-wired auth — and connect to useDeploy's typed endpoints for accounts, teams, and billing instead. Because useDeploy's frontend is Next.js and yours is standard React, most components move with a copy and an import fix. Start it locally with four env vars, run the golden-path test to watch the whole system work end to end, then put your screens on top piece by piece.
