Host your Lovable, Bolt or v0 app
You built it in an afternoon. Now put it somewhere you control: your own domain, your own bill, in EU data centres. Paste your GitHub link, paste your .env, and it's live, with the values your app needs when it builds already in place.
Public repositories deploy straight from the link. Private one? Use the CLI from your project folder.
It built fine. It just can't find its backend.
Apps from AI builders are usually a Vite or Next.js front end. Both copy some settings into
the JavaScript while they build: anything starting VITE_ or
NEXT_PUBLIC_, like your Supabase URL or your API address.
Most hosts only hand your app its environment variables once it's running, which is too late.
The build succeeds, the page loads, and every request goes to undefined.
On velixir those values are passed to the build, so the app you deploy is the app you previewed.
VITE_, NEXT_PUBLIC_ and the like are used at build automatically. Everything else is set when your app runs.
Three steps, about two minutes.
Connect the repository
Sync your project to GitHub from your AI builder, then paste the repository link above. velixir fetches it and works out how to build it, with no Dockerfile.
Paste your .env
The deploy form has a box for your environment variables. They're saved before the first build, so your VITE_ and NEXT_PUBLIC_ values are there when it runs.
It's live
You get a velixir.run address straight away. Add your own domain whenever you like, with HTTPS set up for you.
Whichever tool you used
Lovable and Bolt: Vite and React
Built and served as a fast static site, no server code needed. Links straight to a page inside
your app (/dashboard, /settings) work,
because every unknown path falls back to your app for its router to handle. A static front end is light
enough for the Free plan.
v0: Next.js
Runs as a Next.js server, so server components, API routes and server actions work as they did in the preview. Small apps run on Free; give a busier one a paid plan so it never sleeps.
Your backend stays where it is
If your app talks to Supabase, keep using it: only the front end moves. If you'd rather run the database yourself, add managed Postgres in the same project, in the EU.
Public keys in the build, secret keys never
A value used at build ends up in the JavaScript every visitor downloads. That's fine for the values these frameworks are designed to expose: a Supabase project URL and its anon key are meant to be public, and your data is protected by row-level security.
A Supabase service role key, a Stripe secret key or an OpenAI key is different. If your AI builder put
one in a VITE_ variable, move it to server code before you deploy.
velixir won't let a secret be used at build, so marking it secret keeps it out of the browser.
Questions
Why does my exported app show a blank page on other hosts?
Vite and Next.js copy VITE_ and NEXT_PUBLIC_ values into your JavaScript while they build. Most hosts only provide environment variables once the app is running, so the build has nothing to copy. velixir passes those values to the build, so they're there.
Do I need a Dockerfile or any config?
No. velixir reads your project, sees it's a Vite or Next.js app, and builds it. A Vite app with React, Vue, Svelte, Preact, Solid or Lit is served as a static site; a Next.js app runs with next start.
My GitHub repository is private. Can I still deploy it?
Yes, with the velixir CLI from your project folder: run velixir init, then velixir deploy, and add your variables with velixir env import .env. Deploying straight from a link works for public repositories.
I changed a VITE_ value and nothing happened. Why?
Values used at build are inside the built app, so a restart keeps the old ones. When they change, the Environment tab offers Rebuild now, which builds your app again with the new values. From the CLI, run velixir rebuild.
Will client-side routes like /dashboard work?
Yes. For a Vite app, any path that isn't a file falls back to your index.html, so your app's router handles it, including when someone opens or refreshes a deep link.
Is it free?
You can start free, with no card. The Free plan runs one app that sleeps when nobody's using it and wakes on the next visit, which suits a static front end. Paid plans that never sleep start at €3.49 a month.
Can I use my own domain?
Yes. Add it on your app's Domains tab and point your DNS at velixir. HTTPS certificates are issued and renewed for you.
