Anytype

Overview

Anytype was built by a Swiss/Cyprus-based team to offer a Notion-like block and database editing experience without depending on a company’s cloud servers. Early versions ran on an invite-only closed beta with a proprietary backend, which drew criticism from open source advocates given the project’s positioning. The team subsequently published the client’s source and moved to a local-first architecture built on their own “any-sync” protocol, storing data on the user’s device and syncing directly between devices or through self-hosted infrastructure rather than a mandatory central service.

Anytype’s licensing is not fully open source and should be stated precisely: the underlying any-sync and any-block protocol layers are MIT-licensed, but the actual client applications (desktop, iOS, Android) and the any-heart middleware are released under the Any Source Available License — a source-available license that is not OSI-approved, restricting commercial redistribution. Users can read and self-compile the code, but Anytype does not meet the standard definition of open source at the application layer.

Anytype’s data model is close to Notion’s: pages are built from blocks, and structured data lives in “sets” and “collections” similar to Notion databases, with relations linking objects together. Because the underlying storage is local-first, Anytype spaces remain accessible offline and aren’t tied to the availability of a hosted product, which is the main trade-off users are making relative to Notion’s simpler, always-online cloud model.

Key Features

• Local-first storage — Data lives on-device by default, with peer-to-peer or self-hosted sync
• Block-based editor — Notion-style composable blocks for pages
• Objects and sets — Structured, relational data similar to Notion databases
• Offline access — Full functionality without an internet connection
• End-to-end encryption — Sync traffic between devices is encrypted
• Cross-platform — Native apps for desktop and mobile

Use Cases

• Personal knowledge management — Notion-style notes and databases without cloud lock-in
• Offline-first workflows — Working without reliable internet access
• Privacy-conscious teams — Keeping structured workspace data off third-party servers
• Self-hosters — Running their own sync infrastructure instead of a vendor’s

Who It’s For

Anytype suits users who like Notion’s block-and-database editing model but want their data stored locally and synced without a mandatory central server. It’s a reasonable fit for privacy-conscious individuals and small teams willing to trade some of Notion’s collaboration polish and template ecosystem for data ownership and offline access.
