I'm in your target market, and in my opinion you have an opportunity to rephrase your tagline "The first open-source Infrastructure-as-Code framework" because your tagline makes me think you're ancient and retro-- think back twenty years or more to Capistrano, Chef, Puppet, etc. as just a few examples.

Just to double-check, here's what Google shows me for your own tagline:

"Chef is an open source infrastructure as code framework, or set of solutions and approaches that helps you automate your infrastructure and applications."

"Terraform is an open source Infrastructure-as-Code framework originally created by HashiCorp"

"Pulumi is an open source Infrastructure-as-Code framework that provisions resources utilizing common programming languages."

etc.

If you're open to adjusting your marketing, I can also suggest you add OpenTofu to your homepage where you currently list Terraform. OpenTofu is more up to date with the open source community especially for IaC. It's a crowded space so aim to highlight your value proposition instead of writing "first".

Just my two cents. Hope this helps.
