Frequently Asked Questions

What is Thinkfree Office?

Thinkfree Office is an online office suite that combines a word processor, spreadsheet, and presentation tool in one platform. Unlike cloud-based SaaS products, it can be deployed on-premise or in a private cloud, so your documents and data stay within your own infrastructure rather than on an external server.

The key difference is data location and control. Thinkfree Office can be installed directly on your own servers or private cloud (BYOC), so your documents and user data never leave your infrastructure. This makes it well suited for regulated industries like finance, government, and healthcare where data sovereignty and security are critical.

You can choose between on-premise, private cloud (BYOC), and Hosted API deployment. Self-hosting is the right fit if you want to run the full office suite on your own infrastructure, while the Hosted API is better if you just need to integrate document editing into an existing application quickly. If you’re unsure which fits your case, our self-hosted vs. hosted API guide breaks down the differences.
