Siteleaf vs prismic.io

Hi StackSharers, your help is dearly needed as we're making a move to which we will commit for the next few years.

Problem: As our Marketing team gets growing needs to publish content fast and autonomously, we're trying to add a CMS to our stack.

Specs:

• This CMS should have fairly advanced marketing features: either natively built, and/or be open source, so we can either find third parties' plugins suiting our needs or build our own plugins homebrew.

• "Advanced marketing features" like these: Non-devs should be able to handle content autonomously, Should have a non-dev friendly interface, should allow creating a library of reusable components/modules, should show the preview before publishing, should have a calendar with all publications, should show the history/tracking, should allow collaborating (Google Docs like), should display characters limit optimized for SEO.

Solution: We're considering an SSG + Headless CMS combination. We're fairly confident for the SSG (Gatsby), but we're still uncertain which CMS we should choose.

I wanted to use an open-source CMS for this project so that ruled out a lot of options (Contentful, Sanity, Prismic etc...). The only other open-source option I found worth considering was Payload CMS. Since this was my first headless CMS project, I chose Strapi over Payload CMS. Payload CMS is very powerful and flexible but may be TOO flexible and abstracted for my first crack at this. Strapi also seems to have a lot of momentum which is important for open-source projects.

I've been happy with Strapi so far and it's been able to do what I needed. I may try Payload CMS on a future project now that I have some experience.

Hi Community, Would like to ask for advice from people familiar with those tools. We are a small self-funded startup and initial cost for us is very important at that stage. That's why we are leaning towards Sanity. The CMS will be used to power our website and flutter cross-platform mobile applications.
