The homepage header is about landing your core product message.
For Modal it is basically LLM infrastructure with great developer experience.
And they do a great job delivering it:
- Input/output visual: I think for infra products this is a great choice. Show what code you run, show how to run it, show what you get. Ideally, this all looks nice and easy.
- Headline/subheadline: They explain "what is it" and "for whom is it" (or what use case): "what": Serverless infra platform, "whom" ML teams.
- Great calls to action: If you don't know what to put this is the best baseline imho. Get started (Signup) and Docs.
- Social proof: devs want to know if others like them and/or respectable companies use it in production. While dev testimonials do that better, logos is what people expect to see here. Don't have them and you raise flags, especially if you are unknown.
- Branding: if you can make your page/company memorable on top of landing that message -> great. And with that green gradient and uncommon colours they definitely do.
Top job on that header folks!
