Capacities alternatives: 3 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Bloques tipados, relaciones y vistas de base de datos para quienes disfrutan ver la maquinaria.
licenseAGPL-3.0
runsyour machine or their cloud
installDesktop/mobile package, or Docker image for browser-based self-hosting
enginesBuilt-in AI features connect to OpenAI-compatible APIs using a configured endpoint and key
dataA workspace stores block documents as structured .sy JSON files plus assets on disk; SQLite files hold indexes and auxiliary state; documents can export to Markdown, HTML, PDF, and Word
the catch vs CapacitiesSiYuan exposes blocks, attributes, and database mechanics more directly, so creating and browsing coherent object types is less elegant than in Capacities.
setupThe desktop app installs cleanly, but free cross-device sync is not a turnkey feature: official cloud sync is a paid membership feature and Docker hosting does not transparently become desktop/mobile sync

Las notas se convierten en objetos mediante atributos, relaciones y plantillas reutilizables.
licenseAGPL-3.0+
runsyour machine or their cloud
installDesktop release package, or Docker Compose/image for a server and browser client
dataNotes, hierarchy, attributes, revisions, and most attachments live in a local or server-side SQLite database named document.db; notes can be exported to HTML, Markdown, or OPML
the catch vs CapacitiesTrilium remains fundamentally tree-first, making typed objects and cross-cutting collections feel bolted on compared with Capacities' object-native design.
setupThe desktop app is straightforward, but cross-device sync and browser access require operating a Trilium server, persisting document.db, and handling backups and upgrades

Capacities con la misma obsesión por los objetos, datos locales y solo 100 MB de almacenamiento gratuito de retransmisión.
licenseAny Source Available-1.0
runsyour machine or their cloud
installOfficial desktop or mobile installer; optional self-hosted Any-Sync network for advanced deployments
dataObjects are encrypted and stored locally in Anytype's object store; optional encrypted peer/backup-node copies use Any-Sync, and exports are available as Markdown or Any-Block JSON
the catch vs CapacitiesAnytype's typed-object graph is rougher to navigate and gives up Capacities' polished calendar integrations, object workflows, and built-in AI experience.
setupThe recovery Key must be saved because Anytype cannot recover it; local-only users must manage backups, while synced use is subject to the included network-storage allowance

La gente todavía paga por Capacities porque la gente sigue pagando cuando el sistema de notas es confiable en todos los dispositivos y desaparece en sus hábitos diarios de captura. El costo recurrente compra monitoreo de archivos, manejo de conflictos, indexación, aplicaciones móviles, cifrado, copias de seguridad y migraciones, no solo la interfaz visible. If none of that applies to you, any pick above saves $143.88 a year.
Is there a free alternative to Capacities?
Yes: SiYuan, Trilium Notes, Anytype. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Capacities?
Our verdict is SÍ. El bucle central es lo suficientemente pequeño para que un agente de programación capaz produzca una versión local útil en una sola sesión. Para Capacities, organiza notas vinculadas como objetos tipados, como personas, libros, reuniones e ideas. El límite difícil es el pulido del modelo de objetos, la captura móvil, la sincronización, la integración de calendario y las funciones de IA, además de la sincronización, la colaboración y el pulido de la captura. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/capacities.
