Filarr is a local-first workspace for notes, files, and a knowledge graph that links both. Everything is AES-256-GCM encrypted on your disk by default, with per-file keys. Optional zero-knowledge cloud sync — the server stores only opaque ciphertext. Just shipped E2EE file sharing where the share key lives in the URL fragment, never reaching our servers. Notion + Obsidian + Cryptomator in one app. Free local use, no account needed. Solo €4/mo, Pro €8/mo. Desktop client open source under BSL 1.1.
