Poster CMS 3 – Call for Papers

Hi everyone,

I’m excited to share that development on Poster CMS 3 has officially begun!

This will be a major new version of Poster CMS, built exclusively for Stacks 6, bringing a modernized architecture, enhanced performance, updated PHP version compatibility, and exciting new features — while staying true to the simplicity and power you’ve come to expect.

✅ What’s Planned So Far

  • Stacks 6 only: Poster CMS 3 will be built for Stacks 6 only to deliver better performance and flexibility.
  • Seamless upgrade path: Full compatibility with Poster 2. Just copy and paste your content into Stacks 6 and continue building. Only minimal changes, e.g. to the layout, should be required.
  • Online Markdown Editor: A powerful web-based editor for creating and managing blog posts — working directly with your existing .md files.
  • Alloy Markdown importer: Bring your Alloy blog content over to Poster CMS 3 with minimal effort.
  • Editable content areas: Add individually editable areas anywhere on your site — ideal for clients or micro-CMS needs, which can be changed online via the markdown editor.
  • PHP 8.4 support: Built to work flawlessly with the latest PHP versions.

And yes — Poster CMS 2 is already compatible with the latest Stacks 6 beta!

💡 Your Input Wanted

Now’s your chance to shape the future of Poster CMS. I’d love to hear:

  • What features are missing for you in Poster CMS 2?
  • How are you using Poster today — and what would make your workflow easier?
  • Are you looking for any specific integrations (e.g., search, third-party APIs, image galleries)?
  • Would you use Poster CMS for non-blog use cases? (Documentation, portfolios, client content areas?)

Post your ideas, feature requests, or pain points below — or message me directly 💬

Looking forward to your ideas!

Cheers
Jannis

Great news, Jannis!

  1. I would definitely like to start using Poster 3 for non-blog purposes (along with a blog, of course);
  2. RSS is an important form of communication for me. I would love it, if Poster’s RSS function would include a Full-Post Content capability (instead of, or in addition to, the Summary Content) – the thing you’ve promised to consider.

I’m interested which purposes you think of.

Mainly – documentation. Maybe galleries, too.

In Poster 3, I would like to have maximum compatibility with Iconic Gallery Stack especially in text search.
For example in a post I insert Iconic Gallery with photos of variants of a product with a precise description in each single photo (example “gluten free”).
I would like the Poster 3 search to be able to search for text in the descriptions of the photos for a targeted search, as in this case, “gluten free” product variant.
