Kilvin vs Lovable
Lovable is a strong tool for building a product and putting it in front of the public — a landing page, a SaaS front end, an MVP. Kilvin is for the software a business uses internally: trackers, dashboards, intake forms, approval workflows. The two overlap in how they build and differ in what they’re for.
Where the backend comes from
Lovable generates the front end and typically connects to Supabase for the database and authentication. That works well for a product team, but it means someone owns a separate database account, its schema, and its access rules.
Kilvin includes the databases. The agent creates tables inside your workspace, and every app can use them. There’s no second service to configure or pay for, and your data stays in the same place as your apps and files.
Who the software is for
Lovable projects are meant to be published to the web. Collaborators can work on a project together, and the result is usually a public app.
Kilvin apps are private to your workspace. Your team logs in once and sees what they’ve been granted. Permissions are per app and per dataset, with user groups, and they’re managed by whoever runs the workspace. The intended audience is your staff, not the public.
From prototype to daily use
Both tools build quickly and show you the result as it develops. The difference is the step after. A common Lovable workflow is to build most of an app, export the code to GitHub, and finish it in an IDE. In Kilvin, the workspace is the production environment: when you publish, your team can use the tool, and when you need a change, you describe it to the agent. There’s no handoff to a code editor.
Kilvin as a Lovable alternative for internal tools
Lovable is very good at what it's for. If you're a founder shipping a product to the public, it gives you a polished front end, a Supabase backend, and a path to real code fast. The friction shows up when an teams try to use it for internal software. Someone has to set up and own the Supabase project, work out roles and row-level security, and decide who's allowed to see what. The app is a standalone website, so the second app starts from scratch, and the usual finish line is exporting the code to GitHub - which only helps if there's a developer to receive it.
Kilvin is built for that internal case. The database lives in the workspace rather than in a separate service, so there's nothing to configure or pay for on the side. Apps are private by default and sit behind your team's login, with permissions per app and per dataset that the office manager can run. When you publish, the tool is live for your team; when something needs to change, you describe it to the agent. There's no handoff to an IDE and no second backend to maintain.

|
Best for | Teams running internal tools on shared data | Founders and builders shipping public web apps |
Collaboration | One shared workspace; everyone sees the apps, files, and data they’re permitted to | Collaborators invited per project |
Deployment | One-click publish to your private workspace; hosting, storage, and databases handled | One-click publish to the web; backend hosted separately (Supabase); export to GitHub |
AI-powered development | Agent builds from a description with the whole workspace as context | Agent builds from a description; context is the current project |
Prototyping | Live preview while the agent builds; iterate in plain English | Live preview; iterate in plain English; visual editor |
Security & access controls | Per-app and per-dataset permissions and user groups; HIPAA BAA on Enterprise | SSO and team roles on Business; app-level auth through Supabase |
Form factor | Desktop-style workspace, private to your team | Standalone web app per project |
Databases | Built in; shared across every app in the workspace | External (Supabase), configured per project |
Don't want to build it yourself?
Kilvin's engineers design and build your tools inside your workspace, then host, secure, and maintain them. Most go from first call to live in under a week, with regular progress updates along the way.
When Lovable is the better choice
Lovable is the right pick if you're building something the public will use: a marketing site with an app behind it, a SaaS front end, or an MVP you'll show to customers or investors. Its visual editor is strong, and for front-end polish it's ahead.
Kilvin is the better fit when the software is for your own staff, when you don't want to run a separate backend, when several tools need to share data, or when the person making changes six months from now won't be a developer.
Switching from Lovable
Moving to Kilvin is a rebuild rather than a migration. Your data lives in Supabase, which lets you export tables as CSV. Upload those to your workspace, describe to the agent what the app did and who used it, and the agent builds the new version and seeds its tables from your export.
Because authentication, hosting, and permissions are already part of the workspace, the rebuild is usually shorter than the original build, and you can retire the Supabase project once you're done. If you'd rather hand it off, Managed Build puts a Kilvin developer on the rebuild with regular updates.
