Capacities vs Prowlarr: at a glance
What is Capacities?
Capacities adds whiteboards and a global graph to its object-based notes.
Capacities is a structured personal knowledge tool shipping a named release about monthly. The October release adds whiteboards and a global graph view, a visual layer over existing notes, plus a polish pass. September brought audio recording and transcription, bulk property editing and AI chats that can edit and act on objects. AI image generation and a Pro+ tier with a larger AI budget arrived in August.
What is Prowlarr?
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.

Capacities adds whiteboards and a global graph to its object-based notes.
◆ Current state
Capacities is a structured personal knowledge tool shipping a named release about monthly. The October release adds whiteboards and a global graph view, a visual layer over existing notes, plus a polish pass. September brought audio recording and transcription, bulk property editing and AI chats that can edit and act on objects. AI image generation and a Pro+ tier with a larger AI budget arrived in August.
◆ Where it's heading
Two threads run together: AI that acts inside the workspace (connectors, chats that edit, a paid AI budget) and better ways to see and capture what is already stored (graph, whiteboards, audio). API 2.0 in July opened the space to outside tools.
◆ Prediction
Expect more AI actions inside chats and further work on the graph and whiteboard surfaces; the entries do not say whether whiteboards will reach the API.
Prowlarr
5.0COLLAB
Prowlarr adds Trusted Networks and host validation, then moves to 2.7
◆ Current state
Prowlarr, the indexer manager for the *arr apps, ships patch releases every one to three weeks. 2.6.5 added a Trusted Networks setting and hostname validation, with follow-up fixes to Allowed Hosts logging and health checks. 2.7.0 bundled wildcard IP support in Allowed Hosts, IMDb search for BroadcasTheNet, a longer AvistaZ rate limit and base64 decoding in Cardigann definitions.
◆ Where it's heading
Security settings that limit which hosts and networks can reach the app are the main thread since September, rolled out in step with Lidarr. Indexer definitions keep getting small compatibility fixes.
◆ Prediction
More indexer-level fixes and Allowed Hosts follow-ups are likely in 2.7 patches.
