CryptPad
An open-source suite with documents, sheets, boards, whiteboards, forms, and encrypted storage in cloud or self-hosted form.
Why use it
Unannounced projects, publishing negotiations, and staffing plans can be shared without the server reading content.
Where it fits
Find engines, frameworks, code libraries, version control, and production automation.
What to check
Encryption limits some search, recovery, and integrations, free storage is small, and lost credentials can make data unrecoverable.
