What blog platform to use for my SaaS

My two cents. If you are successful you will eventually have a marketing team. WordPress (self-hosted) requires very little technical know-how to operate. I think that is important because the marketing team can own all things WordPress, keeping your engineering team focused on the product.

For the same reason I think it makes a lot of sense to use WordPress if you are just starting out because it is simple and easy to use. You can just write and you won't burn cycles messing with non-writing tasks to make it work.

Another vote for self-hosted WordPress. It just works and has all the necessary batteries for SEO etc. No need to reinvent the wheel.

WordPress remains the best platform for blogging. You should always self-host the blog because you can control it. There isn't any traffic advantage of hosting it on Medium - you need to build your own traffic. WordPress is easy to install, configure and manage. WP developers are affordable

Is there any specific reason why you need a blog platform? I add posts under /blog and that works fine. Static site, most content is written in markdown so it's super easy.

I'd say use a static site generator (e.g Hugo) with a CMS (like https://forestry.io/).

This gives you the best of both worlds -- never have to worry about your blog going down due to traffic spikes, can host it for nothing (or next to nothing). With a CMS, it'll make it easy to collaborate with non-technical writers down the road.

It's not as easy or familiar as wordpress but much more robust traffic wise

I use https://gohugo.io because I like writing content in markdown with vim
