Is CMSKite a headless CMS?

Yes, for blogs: your site can read published posts over a REST API with a read-only key. Unlike Contentful or Sanity, it also gives you pages that work without a developer: the free blog link and the two-line embed.

Can I add custom fields to CMSKite posts?

No. The post model is fixed. If you need fields of your own, Contentful or Sanity is the better fit.

Is Contentful free for a small business blog?

Contentful has a Free plan with 10 users, 2 locales and 100K API calls a month, which it describes as for learning and exploring. The next plan, Lite, is $300 a month. You still need a developer to build the pages.

Sanity’s Free plan allows up to 20 user seats and 10k documents, which is plenty of room for a blog’s posts. You still need a developer to configure the Studio and build the site that shows them.

Can I move my posts from Contentful or Sanity to CMSKite?

There is no importer. A developer can read the posts from either one’s API and ask an AI tool connected to CMSKite over MCP to create them.

Contentful, Sanity or CMSKite for a blog? General-purpose, or blog-shaped.

Contentful and Sanity are general-purpose headless CMSs: you design the content model, a developer builds every page that shows it, and the result can run anything from a blog to a product catalogue. CMSKite is a headless CMS with the blog already modelled: posts, categories, tags and authors, a dashboard for the people who write, and pages that work before any developer is involved.

DashboardOpen dashboard Start freeNo card. Your blog is live in a minute.

The CMSKite API keys page for a website: a Keys table with each key’s name, masked key, created and last-used dates and status, and a Create key button. — Writers publish in the dashboard; your code reads the same posts with a read-only key.

The short answer

Choose Contentful or Sanity if the blog is one part of a larger content system (product pages, landing pages, an app) that needs fields and structure of your own, and you have developers to build it.
Choose CMSKite if what you need is a blog: writers publish from day one, posts show on a free link or through two lines on any site, and developers still get an API, an SDK and webhooks.

The real difference: who designs the content

In Contentful, each space has a content model made of the content types you create. In Sanity, the Studio is configured in JavaScript or TypeScript, schemas included. Either way a “blog post” is something you define: its fields, its rich text, its search fields, its author. That freedom is the point of both products, and the reason a developer is part of every project.

CMSKite’s model is fixed and shaped like a blog. A post has a title, slug, excerpt, body (Markdown, HTML or plain text), status, one category, up to 50 tags, an author, a featured image, publish and schedule dates, and search settings. You cannot add fields of your own. In return there is nothing to model, and what a blog needs around its posts already exists: a sitemap, a feed, canonical links, article data and reader numbers.

Side by side

	Contentful	Sanity	CMSKite
Content model	Content types you create, per space.	Schemas written in code, in Sanity Studio.	Fixed: posts, categories, tags, authors and images. No custom fields.
Pages for readers	None included: your front end reads content through Contentful’s APIs.	None included: your front end queries content with GROQ or GraphQL.	A free blog link (finished HTML) from sign-up, and a two-line embed for any website. Or your own front end, through the API.
Who sets it up	A developer models the content and builds the site.	A developer configures the Studio and builds the site.	Nobody, to start: sign up and write. A developer only to render posts in your own code.
Free plan	10 users, 2 roles, 2 locales, 100K API calls a month, one Starter Space. Contentful describes it as for learning and exploring.	Up to 20 user seats, 2 permission roles, 2 public datasets, 10k documents, 250k API requests a month.	No card and no end date; the limits are in the table below.
Next plan up	Lite, $300 a month: 20 users, 3 locales, 1M API calls, scheduled publishing, comments and tasks.	Growth, $15 per seat a month.	Starter and Team, below.
Languages	Locales on each entry (2 on Free, 3 on Lite).	Locales on every plan.	A version of each post per language, 30 languages, on every plan.
Search basics for posts	The fields you model, written into pages by your front end.	The fields you model, written into pages by your front end.	Built in: search title, description, canonical link, BlogPosting data, a sitemap and slugs that redirect when renamed.

When Contentful or Sanity is the better choice

The blog is a small part of a bigger content system. Products, landing pages, help articles and an app can share one model and one editing tool. CMSKite holds blog posts and nothing else.
You need fields of your own. A recipe’s ingredients, an event’s date and venue, a review’s score: in Contentful or Sanity you add the field. In CMSKite there is nowhere to put it except the body of the post.
One piece of content in several languages. Both keep locales on the same entry. CMSKite treats each language as a separate post.
Editors need a tool shaped to your workflow. Sanity Studio is code you can change; Contentful adds comments, tasks and live collaboration from its Lite plan.
Your developers want full control of every page. Nothing about what the reader sees comes from the CMS.

When CMSKite is the better choice

The people who write are not developers, and there is no developer yet. Writers publish in the dashboard; posts are live on the free blog link at once, and on any website with the two-line embed.
You do not want to design a blog from scratch. Canonical links, BlogPosting data, a sitemap of posts at their addresses on your site, an RSS, Atom or JSON feed, and old slugs that keep working are already there. What every post gets.
You want reader numbers per post without adding an analytics tool or a cookie, on every plan. Blog analytics.
You want AI drafts that know your business. Write with AI writes into the same fields a person would fill, search title and description included.
Developers still get a proper API. REST with a public OpenAPI document, a TypeScript SDK, an MCP server for AI assistants, signed webhooks, and on paid plans your own MongoDB and storage bucket. For developers.

Using both

Some teams keep Contentful or Sanity for the site’s pages and product content, and use CMSKite for the blog, so writers never touch the main content model. The site’s code reads posts from CMSKite’s API next to its other content, and a webhook on post.published can start the rebuild. The Quickstart covers the key and the first request.

Moving an existing blog across is a developer’s job: there is no importer, but an AI tool connected over MCP can create the posts for you.
