AFFiNE vs Capacities
A side-by-side editorial comparison of AFFiNE and Capacities — release velocity, themes, recent moves, and the top alternatives to consider.
AFFiNE vs Capacities: at a glance
What is AFFiNE?
The nightly canary keeps shipping, and self-hosting just got a one-click path.
AFFiNE publishes a dated canary build most days alongside a slower beta line, and the two carry the same commits at different points on the maturity curve. The recent stream is maintenance-shaped: dependency security bumps in Mermaid and Electron, a journal lookup fix for trashed docs, retry handling for failed transcription jobs. The last directional move was workspace BYOK profiles with model catalogs and key rotation in early August, which sits on top of the MCP credential work from July.
What is Capacities?
Capacities pairs an AI-connected knowledge hub with a real developer API.
Capacities has spent 2026 turning a personal knowledge tool into an AI-connected, programmable workspace. The past two months shipped API 2.0 for developers, AI Chat Connectors that let ChatGPT, Claude, and Cursor create and edit objects, plus steady polish across the editor, dates, and presentation mode. The newest release is a reliability roundup rather than a feature push.
AFFiNE vs Capacities: editorial side-by-side
AFFiNE
6.3COLLAB
The nightly canary keeps shipping, and self-hosting just got a one-click path.
◆ Current state
AFFiNE publishes a dated canary build most days alongside a slower beta line, and the two carry the same commits at different points on the maturity curve. The recent stream is maintenance-shaped: dependency security bumps in Mermaid and Electron, a journal lookup fix for trashed docs, retry handling for failed transcription jobs. The last directional move was workspace BYOK profiles with model catalogs and key rotation in early August, which sits on top of the MCP credential work from July.
◆ Where it's heading
Two threads run in parallel. The AI thread is about who supplies and controls the model - BYOK profiles, MCP credentials, access modes - rather than adding model features. The other thread is self-host ergonomics, and the Render blueprint is the clearest recent instance: AFFiNE keeps lowering the cost of running your own instance while keeping the AI layer pluggable. Between those, the canary absorbs a steady flow of upstream security patches with little product change attached.
◆ Prediction
Expect the self-host track to keep collecting deploy targets and the BYOK work to extend to more provider surfaces; on current cadence the next 0.27 beta will consolidate the canary work rather than introduce anything new.
Capacities
6.3COLLAB
Capacities pairs an AI-connected knowledge hub with a real developer API.
◆ Current state
Capacities has spent 2026 turning a personal knowledge tool into an AI-connected, programmable workspace. The past two months shipped API 2.0 for developers, AI Chat Connectors that let ChatGPT, Claude, and Cursor create and edit objects, plus steady polish across the editor, dates, and presentation mode. The newest release is a reliability roundup rather than a feature push.
◆ Where it's heading
The direction is consistent: make a user's space reachable from both AI assistants and code, then harden it. Capability drops (API, connectors, bulk import, image analysis) now alternate with polish passes that stabilize the surface just expanded. Presentation mode is quietly maturing from a side feature into a first-class output.
◆ Prediction
Next likely move is deeper API coverage or an AI-connector upgrade that writes richer object types — extending the programmable surface it just opened rather than adding a net-new pillar.
