Which is better for someone who doesn't write code?
Both start from a prompt box, so neither asks you to write code to get a first version. Lovable is the narrower of the two, and that is its advantage for a non-developer: it builds web apps, hosts the backend on its own Cloud, and publishes to a lovable.app address from the free plan, so there are few decisions to make. Replit gives you more to hold — a workspace, a terminal, 50+ languages, several kinds of deployment — which pays off the moment you want to look underneath, and is more surface than you need if you never will.
Which one lets you leave with the code?
Both sync with GitHub in both directions, and they differ on the download. Lovable syncs to GitHub, GitLab or Bitbucket on every plan including free, but downloading the code as an archive, and editing it inside Lovable, start at Pro ($25 a month). Replit imports from GitHub and pushes back, and downloads any project as a zip from its file tree with no plan named. One more difference points the other way round: Lovable cannot start from a repository you already have — it exports to GitHub only — while Replit imports one.
How far does each free plan go?
Lovable Free grants 5 build credits a day, capped at 30 in a calendar month, plus 20 Cloud credits and 4 AI credits, and it publishes. Replit's free Starter plan grants daily Agent credits up to a monthly cap and 2GB of workspace storage, but publishes 1 app, which expires after 30 days and has to be published again; it also leaves out Plan Mode and third-party connectors and keeps the Made with Replit badge. For a site that has to stay up, Lovable's free plan goes further.
Which one builds phone apps?
Replit. Its docs walk through building a mobile app and taking it all the way to the App Store: an Apple Developer account, the upload to App Store Connect, TestFlight, and a final review you submit yourself. Lovable builds web apps; its publishing always goes to a web address. Lovable's own FAQ covers the stores only by exporting the code and wrapping the published web app in a third-party tool; Replit is the one of the two that builds the mobile app itself.
When is neither the right answer?
If the thing you care about is the source in a repository you own from the first commit, downloadable without a paid plan, and a phone app submitted for you rather than by you. That is the gap Buildra was built for: every commit its agent makes is mirrored out to a GitHub repository you own, the source downloads on the free tier — 5 credits a day, up to 25 a month, across up to 3 projects — a project can start from a repository you already have, and Buildra submits phone apps to the App Store and Google Play itself. It is the smallest of the three: the mirror runs one direction only, there are no roles, SSO or audit logs, and Lovable's free monthly allowance is larger.
