The core difference: app builder vs. website builder
Lovable is strongest when you're describing an application: authentication, a database, custom workflows, dashboards. It hands you working code you own and can extend.
Bunstation is built around the website use case first: a business needs a site live today, with copy, layout, and responsive design handled, and the option to open the code editor when you want to change something specific.
Bottom line
If the deliverable is a website, Bunstation is the more direct path — it's built for that from the first prompt. If the deliverable is a working app prototype, Lovable's app-first approach is the better tool for the job. Some teams end up using both: Lovable for the product, Bunstation for the marketing site in front of it.
