Strapi is an open-source headless CMS developed by Strapi Solutions. It is released under the MIT license, which allows users to freely use, modify, and distribute the software.

Some key things to know about Strapi's open-source nature:

Strapi core is 100% open source

The core framework of Strapi, including essential features like:

Content modeling
Content management

Plugin ecosystem
Admin panel and user interfaces

Are completely open source and available on GitHub.

Extensive plugin ecosystem

Strapi has a vibrant community of developers who have created over 300 open source plugins to extend Strapi's functionality. These plugins add capabilities like:

SEO optimization
Advanced media management
Multi-tenancy
Internationalization

And many more. You can browse and install these plugins for free.

Optional "Enterprise Edition"

Strapi Solutions offers an enterprise edition of Strapi for businesses that want additional support. This includes:

Overall, Strapi is a fully open-source headless CMS that gives developers flexibility to build customized solutions. Its optional enterprise edition caters to organizations with more advanced needs.

When not to use Strapi?

Strapi is a great open source headless CMS, but it may not be the ideal choice in certain situations:

Difficult to Migrate Existing APIs

If you already have an existing backend or API in place (e.g. WordPress), migrating it to Strapi can be challenging and time-consuming to get an exact match. Strapi works best for new projects rather than migrations.

Limited TypeScript Support

While Strapi offers JavaScript support, its TypeScript capabilities are still limited. If your project relies heavily on TypeScript, other headless CMS options may be better suited.

Not 100% Open Source

The core of Strapi is open source. However, some advanced features are only available in the paid "Enterprise Edition". If you require a 100% open source and free solution, alternatives like Directus may be preferable.

Frequent Updates

As an active open source project, Strapi releases frequent updates. While great for new features and fixes, this rapid release cycle can mean lots of potential breaking changes. If you value stability over bleeding-edge updates, infrequent update cycles may suit your needs better.

So in summary, Strapi works best for new, JavaScript-based projects that don't require full TypeScript support or absolute stability. For other needs, the alternatives listed below may be more suitable.

Is Strapi better than Contentful?

Strapi and Contentful both have their strengths and weaknesses when it comes to headless CMS solutions. Here is a high-level comparison:

Open Source vs Hosted

Strapi is 100% open source and can be self-hosted. This allows for more control and customization, but requires developers for setup/maintenance.
Contentful is a fully hosted SaaS solution. This reduces complexity for development teams, but can get expensive at scale.

Flexibility vs Ease of Use

Strapi offers extreme flexibility to build custom architectures. However, this requires more advanced developer skills.
Contentful simplifies headless CMS adoption through an intuitive interface and rich documentation. However, there are some constraints on data models.

Feature Set

Strapi comes bundled with core CMS features out of the box like authentication, localization, permissions. However, some more advanced capabilities need to be added through extensions.
Contentful offers enterprise-grade capabilities like collaboration, workflows, analytics and has an extensive marketplace of app integrations. However, the core open source feature set is more limited.

So in summary, Strapi excels in customizability given its open source nature, while Contentful leads in usability. Evaluate both options based on your level of technical expertise, budget constraints, and feature requirements.
