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?
AFFiNE ships from a canary firehose — invitations, iOS sharing, and self-host fixes.
Releases land almost daily as dated canary tags, each carrying a single merged pull request with a CodeRabbit-generated summary. The recent run covers three areas: workspace onboarding, where invitation links now require sign-in and can switch accounts mid-accept; mobile capture, with an iOS share sheet that saves URLs, text, web pages, and images straight into a workspace; and self-hosting, including a Render one-click blueprint and a GitHub OAuth fix that had been breaking self-hosted login outright.
What is Capacities?
AI stopped being a bundled feature at Capacities and became the thing you buy more of
Capacities ships a numbered release every few weeks across its knowledge-base app — objects, tabs, the editor, presentation mode — with AI threaded through most of them. Recent releases added a choice of AI model provider, chat connectors, image analysis for Pro users, and in July a full public API. The newest release introduces Pro+ and Believer+, optional paid add-ons that raise the monthly AI budget and sell top-ups on top of it.

AFFiNE
6.3COLLAB
AFFiNE ships from a canary firehose — invitations, iOS sharing, and self-host fixes.
◆ Current state
Releases land almost daily as dated canary tags, each carrying a single merged pull request with a CodeRabbit-generated summary. The recent run covers three areas: workspace onboarding, where invitation links now require sign-in and can switch accounts mid-accept; mobile capture, with an iOS share sheet that saves URLs, text, web pages, and images straight into a workspace; and self-hosting, including a Render one-click blueprint and a GitHub OAuth fix that had been breaking self-hosted login outright.
◆ Where it's heading
Two audiences are being served in parallel. Self-hosters get deployment and authentication work — the OAuth token exchange was failing with a 403 for want of a User-Agent header, which is the kind of bug that blocks adoption entirely until someone hits it. Meanwhile the client work is about getting content into AFFiNE from outside it: the iOS share extension, HTML import that now maps hex, RGB, HSL, and named colors onto the app's themes. The pattern is a product working on capture and onboarding friction rather than new document capabilities.
◆ Prediction
Expect the canary cadence to continue at roughly one pull request per tag, with more import fidelity and mobile capture work, and further self-host deployment targets after the Render blueprint. A stable release consolidating this run is the likely next milestone.

AI stopped being a bundled feature at Capacities and became the thing you buy more of
◆ Current state
Capacities ships a numbered release every few weeks across its knowledge-base app — objects, tabs, the editor, presentation mode — with AI threaded through most of them. Recent releases added a choice of AI model provider, chat connectors, image analysis for Pro users, and in July a full public API. The newest release introduces Pro+ and Believer+, optional paid add-ons that raise the monthly AI budget and sell top-ups on top of it.
◆ Where it's heading
Two arcs are converging. The first opened the product up: API 2.0 made the knowledge base programmable, and connectors let outside assistants reach it. The second is now closing around cost — AI has moved from a bundled capability to a budgeted one, and the new tiers charge for consumption rather than for features. Read together, Capacities is treating the knowledge base as the durable asset and inference as a metered resource priced separately from it.
◆ Prediction
Expect AI budget to become an explicit dimension of the plan comparison, with limits and top-up sizing tuned in follow-up releases. The entries do not show how the budget is measured, so the unit being sold remains unclear.
