Lovable custom domain and login: what it costs, what it cannot do, and the alternative

The short answer

You can put a Lovable app on your own domain on any paid plan. You can also stop strangers from opening the published app by setting website access to your workspace. What you cannot do with a switch is give ten colleagues their own username and password without either making them Lovable workspace members or building an auth system inside the app.

That last part is what most people searching for "lovable login with username and password" want, and it is the part this guide is about.

Custom domains on Lovable

As of 2026, connecting a custom domain requires a paid plan. The Pro plan is $25 a month (about $21 a month billed yearly) and Business is $50 a month. There is no separate charge for the domain feature; you bring a domain you already own, add the DNS records Lovable shows you, and the app is served on it with TLS.

Common snags people search for:

• "lovable custom domain not working": almost always DNS. The records take time to propagate, and if the domain sits behind Cloudflare with the proxy on, the certificate step fails until you turn the orange cloud off for those records.
• "lovable custom domain free": not on the free plan. The free tier publishes to a lovable.app subdomain only.
• "lovable custom domain ssl": issued automatically once DNS resolves. If it does not, it is the DNS again.

Who can open the published app

Lovable separates two things. Project access controls who can open the editor and the code. Website access controls who can open the published URL. Since December 2025 the default for new projects is workspace-only, and since April 2026 fully public projects are gone from the editor side.

For the published website, the choices are, in Lovable's own terms, Public or Workspace. Workspace means a visitor has to be signed in to Lovable and be a member of your workspace. On Business and Enterprise plans you can restrict further to invited users.

That works for a two-person company. For a 15-person office it means 15 Lovable accounts and 15 workspace seats for people whose only job is to open a tracker.

Username and password for your own users

If you want your users to sign up with an email and password inside the app, the standard route is Supabase Auth, which Lovable wires up when you ask for it in the prompt. It is a real auth system and it works. What you take on:

• You now own a Supabase project, with its own free tier limits and its own pricing once you pass them.
• Roles (viewer, editor, admin) are yours to design and test. Row-level security policies are easy to get wrong and the failure mode is silent: someone sees data they should not.
• Password resets, invites, and removing a departed employee are all features you have to build.
• If you later move the app, the auth moves with it, which is good, but it means the app is now three services: Lovable, Supabase, and your domain registrar.

None of this is a criticism of Lovable. It is a product for building apps, and it is good at that. The plumbing for a private team tool is a different job.

The alternative: keep the code, change the host

Lovable lets you export the code to GitHub. Once it is in a folder, the app is just a web app and can be hosted anywhere. On Boat House, the deploy is one command from Claude Code, Codex, or any terminal:

• bh deploy puts the folder live behind Boat House sign-in, with a Postgres database and file storage. If the app has a Dockerfile, it is built; a plain static site is served as is.
• bh share app maria@company.com --tier viewer emails Maria a one-time link. She signs in with her own email and password. No Lovable seat, no Google account.
• bh domain buy company.com --yes buys and points a domain from the terminal, or bh domain point uses one you have.
• bh export app gives you the code and the data in one file if you ever want to leave.

The price is $10 a month a tool, no per-person charge, no card to sign up.
