Adding new pages without generate a build

Technical Questions

Hi @yuval222, We have a default 404 page that you can use, which you can see an example of in our NextJS starter examples here: builder/[[…page]].tsx at 2e199acfe6979ec799724898cdc8b4243e5b1827 · BuilderIO/builder · GitHub

If you wanted to create a custom 404 page within the builder then I would recommend making a new page or section model, which you can call “error-page” or whatever you like, and then based on the logic linked above, instead of the default error page you could do something like:

 if (!page && isLive) {
    return (
      <>
        <BuilderComponent model="error-page"  />
      </>
    )
  }

  return (
    <>
      <BuilderComponent model="page" />
    </>
  )
}

Let me know if that makes sense and works for you!
