First, a reassuring and verifiable fact: a generated application pins its dependencies to exact versions — Next, React, Prisma and the rest are fixed to the precise number, not to a range. So it reinstalls identically two years from now and does not break on its own. What does need upkeep is three separate things: security patches for the libraries, the hosting, and your own business changes. While the application lives at the included URL, the first two cost you nothing; the day you host it yourself or alter its code, it becomes software like any other — and since the code is standard Next.js and Prisma that belongs to you, any developer can pick it up.
An application that runs doesn't decay on its own
Intuition says software "ages" and eventually breaks by itself. That isn't what happens. A generated application's `package.json` pins every dependency to its EXACT version — no range, no "latest compatible": the precise number. Reinstalling the application two years from now rebuilds exactly the same library tree as on day one, and the code itself hasn't moved a byte.
What decays is the environment around it: the certificate that expires, the server being migrated, the Node version a host retires, and above all the security patches that pinned versions no longer receive. That is a difference in kind from "the software breaks", and it completely changes what you need to plan for.
Three separate kinds of upkeep, routinely conflated
The first is library SECURITY: a flaw found in a dependency calls for a version bump. It is the only upkeep with a clock, and it has nothing to do with your business.
The second is HOSTING: the domain, the certificate, the database, the backups. While the application is served at the included URL, the platform carries that — and it is also the precise question to ask, here as with any supplier: what is the backup policy, and how often. The day you bring the application onto your own server, that part becomes yours.
The third isn't maintenance at all, it's WORK: adding a field, a status, a screen because your business changed. That only happens if you ask for it, and it is handled on its own terms — the subject of the guide on evolving your application.
Who can do it, and why nobody has you cornered
The code is standard Next.js and Prisma, exportable as a ZIP archive or pushed to GitHub, and it belongs to you. There is no proprietary dialect and no format only the vendor can read: the developer picking up the file works with tooling they already know, and that is what makes a handover possible without us. It is the exact opposite of a closed tool, where "who will maintain it?" has only one answer — the vendor, for as long as they exist.
The trade-off is worth stating plainly: the day you change that code yourself, the running version stops being the one the platform knows how to regenerate. You gain complete freedom and you take on the upkeep with it. Plenty of small businesses never take that step and never need to — but the door stays open, which is what matters on the day you want to walk through it.
What you actually need to budget for
On bespoke software, industry writing puts corrective maintenance at roughly 15 to 20% of the initial cost per year, and maintenance plus evolutions at around half of total cost of ownership over five years. It is the line almost nobody budgets, and it is what turns a successful project into an abandoned tool three years later.
The arithmetic changes when the initial cost is small and hosting is included: there is nothing to set aside while the application runs as it is. The expense reappears in exactly two places — if you bring hosting in-house, or if you have the code modified. Deciding with those two forks in view beats paying insurance against a breakdown that, on pinned versions, doesn't happen.
