Strapi vs Sanity: Self-Hosted vs Managed CMS

Strapi and Sanity are both headless CMS platforms popular with developers, but they represent fundamentally different architectural choices. Strapi is an open-source, self-hosted CMS — you run it on your own server, control the database, and own the entire stack. Sanity is a managed service — content is stored in Sanity's cloud (the Content Lake), and you customise the editing interface through Sanity Studio.

Strapi launched in 2015 and has grown to over 60,000 GitHub stars, making it one of the most popular open-source CMS platforms. It is built with Node.js and supports PostgreSQL, MySQL, SQLite, and MongoDB as its database. You deploy Strapi to any hosting provider — AWS, DigitalOcean, Railway, or your own servers.

Sanity's managed approach means you never worry about database management, scaling, backups, or server maintenance. The Content Lake handles all of this, and you interact with content through APIs and the customisable Studio interface. For teams that want to focus on content and frontend development without managing infrastructure, Sanity's model removes significant operational burden.

Strapi's self-hosting model gives you complete control over your content infrastructure. Your database runs on your servers, your content never leaves your network, and you can inspect, modify, and optimise every aspect of the system. This is essential for organisations with data residency requirements, strict compliance obligations, or existing infrastructure they want to keep using.

The trade-off is operational responsibility. You manage database backups, server updates, security patches, scaling during traffic spikes, and uptime monitoring. A Strapi instance that crashes at 2 AM is your team's problem to resolve. For teams with DevOps experience, this is manageable. For small teams without infrastructure expertise, it adds significant overhead.

Sanity's managed model eliminates infrastructure concerns. The Content Lake has a 99.99% uptime SLA, automatic backups, global CDN distribution, and managed scaling. You never SSH into a server or worry about database maintenance. The cost is vendor dependency — your content lives in Sanity's infrastructure, and migrating away requires exporting all content and assets. For most teams, the convenience of managed hosting outweighs the control of self-hosting.

Strapi provides full source code access. You can modify the admin panel, create custom controllers and services, add middleware, build custom plugins, and extend the API in any way that Node.js allows. The content type builder creates database models with fields, relations, and validation rules. Custom endpoints can implement any business logic your application requires.

Sanity's customisation operates at the Studio level. You define schemas in TypeScript, create custom input components in React, and build custom document actions and workflows. The Content Lake API is fixed — you query content using GROQ or GraphQL, and mutations follow Sanity's document model. You cannot add custom server-side logic to Sanity's backend; any business logic must live in your frontend application or a separate backend service.

For projects that need custom backend logic alongside the CMS — webhook processing, file transformation, complex data validation, or integration with legacy systems — Strapi's full-stack access is advantageous. For projects where the CMS purely manages content and the frontend handles all logic, Sanity's Studio customisation provides sufficient flexibility with less infrastructure overhead.

Sanity's developer experience is widely regarded as excellent. Schema definitions in TypeScript are expressive and well-documented. GROQ queries are concise and powerful. The next-sanity package provides direct Next.js integration with real-time preview and visual editing. Sanity's documentation is thorough, and the developer community is active and helpful.

Strapi's developer experience is good but involves more friction. Initial setup requires choosing a database, configuring environment variables, and deploying the server. The admin panel provides a visual content type builder that is intuitive for simple models but becomes complex for deeply nested content structures. Strapi's REST and GraphQL APIs are automatically generated from your content types, which is convenient but can produce overly generic endpoints.

Strapi v5 (the current major version) has improved significantly in TypeScript support and API design compared to earlier versions. However, Sanity's developer experience still feels more polished for modern frontend development workflows, particularly with Next.js and React. For backend-focused developers comfortable with Node.js, Strapi feels familiar and powerful.

Strapi Community Edition is free and open source. You pay only for hosting infrastructure — a basic DigitalOcean droplet at $12 per month can run Strapi with PostgreSQL for small to medium projects. Strapi Cloud (their managed hosting) starts at $99 per month for the Pro plan. The Enterprise Edition with SSO, audit logs, and premium support requires custom pricing.

Sanity's free tier includes generous usage limits — 500K API requests per month, 20GB bandwidth, and 10GB asset storage. The Growth plan at $15 per project per month increases these limits. Enterprise pricing is custom. Because Sanity charges based on API usage rather than per-seat, costs scale predictably with traffic.

For budget-constrained projects, self-hosted Strapi is the cheapest option — effectively free beyond infrastructure costs. However, when you factor in the time cost of managing infrastructure, Sanity's $15 per month Growth plan provides better total value for teams whose time is expensive. The comparison changes at enterprise scale where Strapi Cloud at $99+ per month competes less favourably against Sanity's usage-based model.

Both platforms support rich content modelling with different approaches. Strapi's content type builder is visual — you add fields through a UI, define relations between content types, and configure validation rules. The resulting models map directly to database tables, making the data structure transparent and queryable with standard SQL tools if needed.

Sanity's schemas are defined in TypeScript code. Document types, objects, arrays, references, and custom types are all specified programmatically. Portable Text — Sanity's rich text format — stores structured content as a data tree rather than HTML, enabling multi-channel content delivery. Content in Sanity is stored as JSON documents in the Content Lake, not in relational database tables.

Sanity's Portable Text is particularly powerful for content that must render across multiple platforms (web, mobile, email). Because rich text is stored as structured data rather than HTML strings, you can render it differently for each platform. Strapi's rich text is stored as HTML or Markdown, which works well for web delivery but requires transformation for other platforms.

Choose Strapi if self-hosting is a hard requirement, if you need custom server-side business logic alongside your CMS, or if you want complete ownership of your content infrastructure. Strapi is the better choice for backend-focused teams who want a CMS that fits into their existing Node.js architecture. The open-source Community Edition provides excellent value for budget-conscious projects.

Choose Sanity if you want a managed service with excellent developer experience, real-time collaboration, and best-in-class Next.js integration. Sanity is the better choice for frontend-focused teams who want to focus on building great user experiences without managing CMS infrastructure. The pricing is fair and scales predictably with usage.

For most modern web projects — particularly those using Next.js or similar React frameworks — Sanity's managed model and developer experience provide a smoother path to production. For projects with specific infrastructure requirements, legacy system integrations, or teams with strong Node.js backend expertise, Strapi's self-hosted flexibility is the deciding factor.
