About ThinCMS
Built from frustration
ThinCMS started as an internal tool. We were tired of managing dozens of WordPress installations for our clients — the constant updates, the plugin conflicts, the 3 AM security alerts. So we built something better.
From internal tool to product
We ran a web development agency. We managed client websites. And like every agency, we spent more time maintaining WordPress than building things our clients actually needed.
Every new client meant another WordPress installation. Another set of plugins to maintain. Another database server to monitor. Another target for automated attacks. We were spending 40% of our time on infrastructure that had nothing to do with content.
So we asked ourselves: what if one installation could serve all our clients? What if the database was just a file? What if security meant having less attack surface instead of more firewalls? What if AI could handle the routine content management tasks?
ThinCMS is the answer to those questions. We built it on Next.js because that's what modern development looks like. We chose SQLite because simplicity beats complexity. We added multi-tenant architecture because one installation should serve many sites. And we built in MCP integration because AI agents are the future of content management.
When we showed it to other developers and agencies, they wanted it too. That's how an internal tool became a product.
Our principles
Less is more
Every feature in ThinCMS earns its place. We don't add functionality to check a marketing box. If it doesn't solve a real problem for real developers, it doesn't ship.
Own your stack
Self-hosted means self-owned. Your data, your server, your rules. No vendor lock-in, no surprise pricing changes, no third-party outages taking your sites offline.
Honest marketing
We tell you what ThinCMS does well and what it doesn't. We're not trying to replace every CMS — we're building the best option for developers and small agencies who want simplicity.

Source-available by design
ThinCMS is source-available. You get the complete codebase with your license. Read it, audit it, customize it, extend it. We believe that if you're self-hosting software, you should be able to understand exactly what's running on your server.
This approach means you're never locked in. If ThinCMS stops being the right tool for you, you still have full access to your data (it's a SQLite file) and your code (it's in your Git repository). We earn your continued business by being useful, not by making it hard to leave.
