How do I move an AI-built app to production properly?

An AI builder gets you a working app fast, often on its own temporary-looking subdomain with no real plan behind it for what happens when something goes wrong. Moving that app to production, meaning genuinely live and relied on, isn't a single step. It's a short, specific checklist, and skipping any item on it is usually what turns a small problem into a real one.

Step 1: Real hosting and a custom domain

Netlify is a platform that deploys and hosts websites and apps directly from your code, from an AI tool's output, or from a connected Git repository, and it's a sensible home for the front-end half of most AI-built apps once you're ready to go live properly. Its current plans, checked directly: Free includes 300 monthly credits with custom domains and SSL included at no extra cost; Personal runs $9 a month with 1,000 credits and adds smart secret detection; Pro runs $20 a month with 3,000 credits and supports unlimited team members. Credits cover usage like production deploys (15 credits each) and bandwidth (20 credits per gigabyte), so a typical small business app comfortably fits the free or Personal tier.

Point your own domain at it rather than staying on the builder tool's default subdomain. A business running on yourcompany.com looks and feels more trustworthy to customers than one running on a generic test address, and it also means you're not locked to one tool's hosting if you ever need to move the app elsewhere.

Step 2: Monitoring, so you find out first

Finding out your app is broken from a customer complaint, hours after the fact, is a worse experience for everyone than catching it the moment it happens. Basic monitoring, an alert that fires the moment a deploy fails or the app goes down, is worth setting up before launch, not after the first real outage. Netlify's own extensions and deploy notifications cover this at a basic level without needing custom code. Getting a Slack alert when a build fails shows one way to route those alerts.

Step 3: A real backup, separate from the live app

Whatever database sits behind your AI-built app needs a backup that exists independently of the live app itself, not just the AI tool's own "undo" history. If the live data is ever accidentally changed or deleted, including by an AI-assisted edit gone wrong, a separate, recent backup is what actually gets you back to a working state. Confirm you know how to restore from it before you need to, not during an actual emergency.

Step 4: A written support plan

Decide, before launch, who gets alerted when something breaks, and what they're actually supposed to do about it. For a small team, this can be as simple as "if the deploy-failure alert fires, I check it within the hour, and if I can't fix it myself within a day, I call in help." Writing this down, even briefly, before launch means you're not improvising a plan during an actual outage, which is the worst possible time to figure one out.

The full pre-launch checklist

1. Custom domain connected, pointing away from the builder's default subdomain.
2. HTTPS and SSL confirmed working, which comes included on Netlify's plans without extra setup.
3. A deploy-failure or downtime alert set up, going somewhere you'll actually see it.
4. A real backup of your data, confirmed restorable, stored separately from the live app.
5. A written answer to "who gets alerted, and what do they do" for the most likely failure.
6. Security and payment checks from a dedicated review completed; my AI-built app security checklist covers exactly what that should include.

If your AI tool connects through Netlify's agent integration

Some AI coding tools can connect directly through Netlify's agent integration, which gives every AI-made change its own preview deploy at a unique address before you decide to publish it live. If your builder tool supports this, it's worth using during the final weeks before launch specifically, since it means you can see exactly what an AI-suggested change will do before it reaches real customers, rather than publishing and hoping.

A realistic launch-week timeline

Spreading this checklist across a short week, rather than trying to do it all the morning of launch, makes it far less stressful and far less likely something gets skipped under time pressure. A workable pace: connect the custom domain and confirm HTTPS a few days ahead, since domain changes sometimes take time to propagate and you don't want to discover that the night before. Set up the deploy-failure alert and test it deliberately by breaking something small in a test environment, confirming it actually reaches someone, a day or two before launch. Confirm the backup exists and, importantly, that you've actually tried restoring from it at least once, the day before. On launch day itself, the only new task is watching the alert channel closely for the first few hours after going live, since that's when an issue, if there is one, is most likely to surface.

Common mistakes at this stage

• Treating "it's deployed" as the same as "it's monitored." A deploy succeeding tells you the code published. It tells you nothing about whether the app is actually working correctly for a real visitor five minutes later.
• Never actually testing the backup restore. A backup you've never restored from is a backup you're assuming works, not one you know works. Test it before you need it for real.
• Launching on the builder's default subdomain "for now," then forgetting to switch. Set the custom domain up before launch, not as a follow-up task that quietly never happens once the app is live and attention moves elsewhere.
• Skipping the security review because the production checklist feels like enough on its own. This checklist covers hosting and reliability. It doesn't replace a dedicated look at data access rules and payment logic, which is a separate, equally necessary step covered in my security checklist.

What if the AI tool itself handles hosting already?

Many AI app builders, Emergent included, offer their own hosting as part of a paid plan, and for a genuinely low-stakes internal tool, staying on that built-in hosting is often fine and simpler than setting up a separate platform. The questions worth asking before deciding to stay there specifically: does the built-in hosting support your own custom domain, is there any monitoring or alerting at all if the app goes down, and is there a real backup mechanism separate from the app's own undo history. If the honest answer to any of these is no, and the app matters enough that downtime or lost data would be a real problem, that's the specific signal to move the hosting to a dedicated platform rather than staying on the builder's default setup out of convenience. Where Emergent hosts your app and how to move it covers that case in detail.

How I'd approach this

When a client is ready to take an AI-built app live for real, I work through exactly this checklist with them: proper hosting on their own domain, monitoring that actually alerts someone, a backup that's been tested, and a plain answer to what happens when something breaks. None of this needs to be expensive or complicated for a typical small business app. It just needs to actually be done before launch rather than assumed, because the gap between "it works" and "it's genuinely ready to run your business" is almost always exactly this list.
