Squidex review
Open source, self-hosted
Squidex is a .NET headless CMS built on event sourcing, meaning every change is an event and the full history of a document is inherent to the architecture rather than a feature bolted on. It is 100% MIT licensed with no enterprise edition, which is rarer than it should be.
The managed cloud is priced in euros and starts very low, and self-hosting via docker-compose or Kubernetes costs nothing in software.
Who Squidex is for
Teams on .NET who want an open-source CMS without an open-core catch, and anyone who wants complete content history as a structural guarantee.
Less suitable for marketing teams: the editing interface is developer-shaped.
Strengths and limits
What it does well
- Genuinely 100% MIT with no gated features, which distinguishes it from most open-source CMS options here.
- Event sourcing gives complete, reliable content history and audit by design.
- Cloud pricing is among the cheapest here at €19 a month for 100,000 API calls and 10 contributors.
- REST and GraphQL both available with no extra work.
Where it falls short
- MongoDB is required, which is a specific operational commitment for self-hosting.
- The editor experience is functional rather than polished, and it is not a tool for a marketing department.
- Small community relative to Strapi or Directus, so fewer worked examples.
- Cloud tiers cap API calls tightly at the low end: 20,000 a month on the free Starter tier.
Squidex pricing
Self-hosting is free under MIT with no limits; you run it on Docker or Kubernetes with MongoDB.
Squidex Cloud: Starter is free with 20,000 API calls, 2GB traffic, 500MB storage and 2 contributors. Basic is €19 a month with 100,000 calls, 20GB traffic, 5GB storage and 10 contributors.

Verdict
Underrated, especially for .NET teams who want an open-source CMS with no licence asterisk. Event sourcing is a genuinely good architectural fit for content.
The editor experience is the limiting factor. If non-technical people will use it daily, look elsewhere.
