Free, open-source alternatives to Evernote

Evernote collects notes, files and clipped web pages into notebooks, tags them and keeps everything searchable and synced across devices. The open-source apps below cover the same core job: a general notes library with notebooks or tags, search and synchronisation between devices.

Joplin is the closest match in structure, with notebooks, to-dos, attachments and a choice of sync targets, including services you run yourself. Notesnook and Standard Notes put end-to-end encryption at the centre of their sync, and Simplenote keeps things light, with plain-text notes sorted by tags rather than notebooks. Trilium Notes arranges a large library in a tree of rich notes and attachments, with optional sync through a server you host. Their hosted services, where offered, have their own plans and limits.
