Lovable, Bolt, Replit, Base44: hosting compared

Every AI app builder answers “how do I host this?” a little differently, and the differences don’t show up until you’ve got real users. This is a side-by-side of what each platform actually gives you out of the box, and where it stops being enough.

We wrote a full deep-dive on each platform separately (linked below); this page is the map that ties them together.

The short version

Platform	Database	Backups	Scaling limit that bites first
Lovable	Managed Postgres via Lovable Cloud	Daily snapshots, ~14-day retention, destructive restore	No point-in-time recovery, no own-Postgres export by default
Bolt.new	Shared connection pool	Platform-dependent	Connection limits under concurrent load (details)
Replit	Included Replit DB or connected Postgres	Platform-dependent	“Always On” keeps the process awake, but isn’t production hosting (details)
Base44	Managed, bundled with the platform	Platform-dependent	All-in-one bundling: no custom backend, no infra control (details)
v0	Connected database, limits vary by provider	Provider-dependent	Database limits that don’t show up until traffic grows (details)

What they all have in common

Every platform on this list is optimized for the same thing: get you from prompt to working app as fast as possible. That means the database, backups, and hosting are bundled, managed, and mostly invisible while you’re building. That’s a genuine strength early on. It’s also why none of them are built to be someone’s production infrastructure for the long run: the bundling that makes them fast to start with is the same bundling that limits what you can control once you have real users and real data.

Where each one actually runs out

Lovable gets you real Postgres through Lovable Cloud, which is further than most builders go. The gap is retention and restore: daily snapshots for about 14 days, and a restore that’s destructive (anything written after the snapshot you restore to is gone). No point-in-time recovery. If a bad migration or a bad actor touches your data at 2 p.m. and you don’t notice until 6 p.m., “restore to last night’s snapshot” costs you the whole day.

Bolt.new apps tend to fail quietly under concurrent load rather than dramatically. The app works perfectly while you’re the only one testing it, then a real launch sends 30 people at once and some of them hit connection errors. It’s rarely a code bug; it’s usually the connection pool. See the full breakdown.

Replit’s “Always On” is the feature people reach for first, and it solves exactly one problem: your process doesn’t sleep. It doesn’t add backups, monitoring, a real database, or anyone watching for downtime. See what it actually covers.

Base44 is the most bundled of the group: frontend, database, auth, and hosting as one managed unit, with no way to peel off just the infrastructure layer. That’s fast until you need something the bundle doesn’t offer. See the signs you’ve outgrown it.

v0 is strongest on the frontend and weakest on making database limits visible before they bite. Whatever provider it’s connected to has its own ceiling, and v0 doesn’t surface it until you hit it. See what changes at scale.

What “outgrowing” actually looks like

It’s rarely one dramatic moment. It’s a pattern: a backup you’ve never tested, a database you can’t export cleanly, a connection limit you didn’t know existed until launch day, and nobody but you who could fix any of it at 3 a.m. None of that means the platform failed. It means the app succeeded past what the platform’s hosting was built for.

FAQ

Do I have to leave my AI app builder to get real hosting?

No. You keep the app and the workflow you’re used to for building; Stackbastion takes over what happens after you hit deploy; your own Postgres, tested backups, monitoring, and a named engineer on call.

Which platform is “worst” for hosting?

None of them are bad at what they’re built for, which is speed to a working app. All five hand you the same category of gap once you have real users: no independently tested backup, no full control of your own database, and no human accountable if something breaks in production.

My platform isn’t on this list. Does the same logic apply?

Almost certainly. Cursor, Windsurf, Claude Code, and Framer AI all follow the same pattern: fast to build, bundled or minimal on the operations side. Check our platform-specific posts or get an audit either way.
