CryptPad: the self-hosted, private alternative to Google Docs

What It Is and What It Replaces

CryptPad is a collaborative document suite that offers an alternative to Google Docs. Like its commercial counterpart, it supports real-time editing of documents, spreadsheets, presentations, and forms. It aims to replace the need for cloud-based productivity tools by providing similar functionality with stronger privacy protections.

Why Self-Host It for Privacy

CryptPad provides end-to-end encryption by default. This means that data is encrypted on the user's device before it leaves their computer, and remains unreadable to anyone managing or hosting the server — including administrators of the self-hosted instance. Unlike Google Docs, where content may be processed through third-party systems and indexed for advertising purposes, CryptPad ensures zero-knowledge encryption: no one but the users can access the unencrypted data.

What Setup Actually Involves

CryptPad is open source software licensed under AGPL-3.0 and designed to be deployed via Docker. While this makes it technically accessible, setup difficulty is considered medium due to dependencies on system administration knowledge such as configuring a web server, handling SSL certificates, and managing container environments.

• Users comfortable with command-line tools and basic Linux administration will find the process manageable.
• Those without technical experience may find Docker configuration or dependency management fiddly and time-consuming.

Cost vs Google Docs

CryptPad is free to use, both in terms of software licensing and server costs (if self-hosted). In contrast, Google Docs requires a free account for basic access but charges for advanced features through Google Workspace subscriptions. For organizations or individuals seeking cost-effective collaboration tools without recurring fees, CryptPad offers an attractive alternative.

Who It’s For and Who Should Not Bother

CryptPad is ideal for users who prioritize privacy over convenience and are willing to invest time in setup. It suits small teams, activists, journalists, or anyone handling sensitive data that should not be exposed to third parties.

• It is not suitable for non-technical users looking for a plug-and-play solution without configuration.
• Users who rely heavily on Google's ecosystem and integrations may find the transition less seamless due to limited external compatibility features in CryptPad.

How to Get Started

To begin using CryptPad, visit https://cryptpad.org. For self-hosting, follow these first steps:

• Install Docker and a compatible Linux environment.
• Clone the official repository from GitHub or use pre-built images.
• Configure your server with HTTPS using Let's Encrypt or another SSL provider.
• Access CryptPad via your browser once deployment is complete.

Documentation for setup and configuration can be found on the project’s website.
