Nextcloud vs Stackfield

Synchronisation et partage sécurisés de fichiers

Synchronisation chiffrée de bout en bout sur tous les appareils, avec liens publics, permissions et dates d'expiration. Avantages : accès distant sécurisé sans fuite de données — idéal pour les équipes manipulant des fichiers sensibles.

Collaboration et bureautique en temps réel

Intégration de Collabora et OnlyOffice pour l'édition collaborative de documents. Talk permet chat et visioconférence. Productivité comparable à Google Workspace, mais auto-hébergée pour la confidentialité.

Groupware et suite de productivité

Calendrier, contacts, mail et tâches dans une seule application. Flow automatise les workflows ; Assistant utilise l'IA locale pour traductions et résumés. Centralise les outils et réduit la fragmentation applicative.

Optional client-side E2E rooms (AES-256 + RSA-2048)

Rooms and direct messages can add browser-side end-to-end encryption so Stackfield cannot read covered content at rest. Admins can force E2E, ban it, or let creators choose. Trade-offs include room-password recovery after login resets, limited lock-screen/email previews, and client-side search cost—plan org policy before migrating sensitive rooms.

Tasks, Gantt, portfolios, and workflows in the same rooms as chat

List/Kanban/Gantt views, milestones, dependencies, automatic scheduling, critical path, custom fields, time tracking, reports, and project portfolios sit next to room chat and discussions. Suited to PMOs that refuse a separate tool silo; less deep than specialist ALM suites for software engineering pipelines.

Video conferences, screen share, and guest/external roles

Built-in audio/video/screen-sharing (plan-dependent) plus guest and external roles that only see assigned rooms. Useful for law firms, agencies, and public-sector projects with outside counsel or contractors without granting full org access.

Germany cloud (IONOS) plus commercial on-premise

Cloud tenants store data in German data centres; Stackfield names IONOS SE as infrastructure provider and claims no AWS/GCP/Azure product subprocessors. On-premise is a paid subscription (vendor-installed/updated, high minimum seat count) for air-gapped or policy-bound estates—test first in cloud; local PoC installs are not offered.

Enterprise access controls and in-product DPA

Higher tiers add enforced 2FA (including YubiKey options), IP allowlists, password policies, SSO, API provisioning, org-wide exports, and compliance-confirmation workflows. Organisation admins can conclude the GDPR DPA inside settings and download the signed PDF once per organisation.
