Sanity holds a wide lead for real-time editing, structured content, and flexible APIs. For front-end developers seeking a simple API to pull content from, Contentful is the usual answer.
What you're looking for is typically called a headless CMS (Content Management System) — a platform that combines an API for developers with a visual content-editing interface for non-technical authors.
The key is to find one where authors can create, preview, approve, and publish content without needing to understand APIs or edit code, while your website, mobile app, or other front end retrieves content through an API.
Best API-driven content platforms to consider
1. Storyblok
(Best match for visual editing)
A visual, component-based editor lets authors click page elements, edit content, and preview changes on the actual site. Developers expose the content through an API and control the front end.
Best for: Marketing sites, landing pages, and teams that want a page-building experience.
A flexible content platform with a customizable editing studio, structured content, and real-time collaboration. Its visual editing features let authors preview pages and jump from page elements to the fields that control them.
Best for: Content-rich products, complex content models, and teams that want a customizable authoring experience.
A mature API-first CMS with a structured editing interface, reusable content models, and REST and GraphQL APIs. It is particularly suited to teams managing content across multiple channels.
Best for: Enterprise publishing, governance, localization, and multiple digital products.
An open-source CMS with an admin panel for managing content and built-in REST and GraphQL API options. You can self-host it or use its cloud offering. Its standard editing interface is more form-based than Storyblok's visual page editor.
Best for: Teams that want infrastructure control, extensibility, and less vendor lock-in.
These are broad capability distinctions; exact visual-editing features, plan limits, and pricing depend on the platform and plan.
My recommendation
Start by evaluating Storyblok if the most important requirement is letting non-technical authors edit and publish pages visually. Evaluate Sanity if structured, reusable content and a customizable editorial workflow matter more.
One important distinction: a headless CMS usually provides the content API and authoring interface, but you still need a front end to display the published content.
Let me narrow it down
1. What are you building?
Website or marketing site
Web or mobile application
Multi-channel platform (web, mobile, other APIs)
Internal content platform or knowledge base
2. What kind of visual interface do authors need?
Edit the page visually, with a live preview
Simple forms for articles, fields, images, and metadata
If you just want a dead-simple, lightning-fast API to pull content from without dealing with enterprise bloat, heavy infrastructure, or annoying configuration, front-end developers typically gravitate toward a few distinct options depending on how "simple" you want to go.
Here are the best choices for a front-end developer looking for a straightforward JSON/GraphQL API:
Ghost (as Headless) : If your content looks like a blog, documentation, or regular articles, Ghost CMS is arguably the cleanest choice. It gives you a gorgeous, distraction-free admin UI for writing, and its Content Delivery API is a pristine, read-only JSON API that requires almost zero configuration to query.[](https://jamstack.org/headless-cms/)
Prismic : Famous for its developer experience with modern JS frameworks (React, Vue, Svelte), Prismic uses a component-driven approach called "Slices". You define your visual sections in code, map them to Prismic, and pull clean JSON data via their simple REST/GraphQL client. It gets out of your way faster than Contentful or Strapi.
Sanity.io : Slightly more advanced, but worth mentioning because its API is so powerful. It treats content like a flexible JSON document store and uses GROQ (a query language akin to SQL for JSON) to let you shape the exact response payload you want on the front end.[](https://www.digital4design.com/blog/best-headless-cms-for-developers/)
To help narrow this down:
What kind of content are you managing (e.g., a simple blog, a marketing site, a mobile app backend)?
Do you prefer a hosted cloud dashboard or defining your content models directly in code/TypeScript?
If your priority is “I’m a frontend developer; give me content through a clean API and get out of my way,” I’d shortlist these:
CMS
API experience
Best fit
Sanity
Excellent — GROQ, REST, GraphQL, JS/TS client
Best general choice
Payload
REST + GraphQL, TypeScript-first
Next.js/TypeScript developers who want more control
Contentful
Structured editor + preview options
REST, GraphQL
Managed
Strapi
Admin panel and content forms
REST, GraphQL
Self-hosted or cloud
Directus
REST + GraphQL generated from your DB
You want CMS + database
Strapi
REST + GraphQL
Self-hosting and customization
Contentful
REST + GraphQL
Larger teams / enterprise workflows
My pick: Sanity
For a frontend developer who doesn't want to spend much time thinking about the CMS, Sanity is probably the first one I'd try.
Its big advantage is that the content model is structured data rather than “pages in a CMS.” You define schemas in code, then consume the resulting content through its API. Sanity provides an official JS/TS client, and its Query API uses GROQ; it also has REST and GraphQL options.
A frontend request can conceptually be as simple as:
Payload — If you're heavily invested in TypeScript/Next.js and want the CMS to feel more like part of your application. Current comparisons consistently put it among the strongest developer-first options.
Directus — If you already have a PostgreSQL/MySQL/etc. database and essentially want “put a nice CMS UI and API on top of my database.”
Strapi — If self-hosting and owning the backend matter. It provides REST and GraphQL and can be self-hosted.
Contentful — If you're building for a larger organization with more elaborate editorial/governance requirements. It's arguably more CMS than you need for a simple frontend project.
Storyblok — If the editor needs to visually construct pages from components. That's useful, but unnecessary if your goal is simply “give me JSON.”
So, for your exact description: Sanity first, Payload second, Directus if you already have a database.
If you tell me whether you're using Next.js, Astro, React, Vue, etc., I can narrow it down to 2–3 options and show what the actual API-fetching code looks like for each.
