Should we deploy Collabora Online (Nextcloud Office) or ONLYOFFICE?

Choose Collabora Online when open document standards (ODF), server-side rendering security, and WOPI integration are priorities; choose ONLYOFFICE when pixel-perfect Microsoft Office (DOCX/XLSX/PPTX) compatibility and a familiar ribbon UI matter most to your users. In both cases, we deploy dedicated document server containers rather than the built-in single-node development server.

How does the Nextcloud + OpenProject + Keycloak integration work?

Both Nextcloud and OpenProject authenticate against the same Keycloak OIDC realm. OpenProject work packages link directly to Nextcloud files, and Nextcloud's Automatically Managed Folders dynamically grant project members file access based on their OpenProject roles.

Can we run Nextcloud Assistant and Context Chat completely on-premise?

Yes. We connect Nextcloud Assistant and Context Chat to self-hosted inference servers (vLLM, Ollama, or LocalAI) and local vector stores so employees can summarize documents, query project folders, and transcribe Talk meetings without sending a single byte to external cloud APIs.

Do you offer managed operations or handover to our internal IT team?

Both. We can design, deploy, and hand over the complete stack with GitOps/Ansible playbooks, backup verification, and admin training—or support your team on an ongoing retainer for major Hub upgrades and monitoring.

Nextcloud enterprise consulting, integration & sovereign hosting

Why Nextcloud succeeds as an integrated platform—and stalls as a standalone install

Installing Nextcloud on a single VM is easy; operating Nextcloud Hub for hundreds or thousands of users requires deliberate systems engineering. Without centralized OIDC/SAML identity, tuned PHP-FPM/Redis/PostgreSQL/S3 storage layers, dedicated Collabora or ONLYOFFICE document servers, and clean hooks into your project and workflow tools, Nextcloud quickly becomes an isolated file silo. We design, integrate, and migrate enterprise Nextcloud environments that fit seamlessly into your existing IT landscape.

What we deliver

Identity, SSO & directory integration (Keycloak, AD/LDAP, Entra ID)

Single Sign-On via OpenID Connect (OIDC) or SAML 2.0, automated group and team-folder provisioning, fine-grained ACLs, and shared token exchange across connected apps.

Deep application integrations (OpenProject, Office, n8n, ERP/DMS)

Bi-directional OpenProject work-package file linking with automatically managed project folders, standalone Collabora Online or ONLYOFFICE clusters, and event-driven n8n/OCS/WebDAV automations.

High-availability architecture, S3 storage & local AI Assistant

Kubernetes or multi-node deployments with S3-compatible object storage, Redis locking, High-Performance Backends (Notify Push, Talk signaling), and Nextcloud Assistant Context Chat wired to self-hosted LLMs (Ollama, vLLM, LocalAI).

Engineering standards in production

How we keep Nextcloud fast, compliant, and maintainable

Server & storage tuning from day one

Dedicated Redis transactional file locking, PostgreSQL connection pooling, S3 primary storage, and Rust-based Notify Push so desktop and mobile sync stays instantaneous.

Sovereign AI without silent data export

Nextcloud Assistant, Context Chat, and Context Agent configured strictly opt-in against self-hosted models or approved EU endpoints—with EU AI Act content labeling enabled.

Auditable SharePoint / OneDrive migrations

Phased migration of folder hierarchies, group permissions, and external share policies with checksum verification and rollback checkpoints.

When engagement makes sense

Replacing or complementing Microsoft 365 / SharePoint

When public-sector rules, client confidentiality, or GDPR/Schrems II requirements demand sovereign document storage and collaborative editing under your control.

Integrating Nextcloud with OpenProject, Keycloak & n8n

When you want one cohesive open-source workplace where login, project tasks, shared folders, and automated document workflows work together without manual admin overhead.

Fixing performance bottlenecks on an existing instance

When slow WebDAV syncs, Collabora/ONLYOFFICE timeouts, or database lock contention need an architectural audit and production hardening.
