Best OneNote Alternatives (2026)
Microsoft OneNote is a free digital notebook app by Microsoft with rich media support and cross-platform access.
TL;DR Note Cargo is the #2 OneNote alternative. Unlike OneNote, Note Cargo uses plain Markdown files stored in your own S3/R2 bucket — no Microsoft ecosystem required, no OneDrive dependency.
It's self-hosted, runs on ~30 MB RAM, and deploys with a single Docker command. Your notes are portable plain text files accessible from any browser.
Plans start at a one-time $4 with no subscriptions. Note Cargo wins on data ownership and Markdown portability — OneNote wins on freeform layouts and handwriting support.
