Login Fatigue
Users authenticate 5-10 times daily across separate apps. SSO exists but requires custom integration for each tool. Password managers become mandatory, not convenience.

THE PROBLEM
The Workplace Tech Paradox
European organizations invest millions in open source workplace apps—email, document collaboration, project management, video conferencing—yet these tools remain isolated islands. Users juggle multiple logins, data sits in silos, and workflows break at app boundaries. The promise of open source flexibility becomes a burden of fragmentation.
Data Islands
Customer mentions in email don't link to CRM records. Meeting notes live separately from project tasks. Search works within apps, never across them. Knowledge scatters.
Context Switching Tax
Moving between apps means mental model switching. Different navigation patterns, inconsistent terminology, no shared workspace. Productivity bleeds at every boundary.
THE VISION
From Fragmentation to Unity
Open Buro orchestrates existing apps into a cohesive platform—no vendor lock-in, no rip-and-replace.
Universal Packaging
Standard app format. One registry. Any publisher can contribute.
Shared Navigation
Common home, unified app grid, global search. Users never lost.
Cross-App Data
Business objects flow between apps. Semantic graph connects knowledge.
Collective Identity
Organization-wide groups, permissions, presence. Manage once, apply everywhere.
Open Buro doesn't replace your apps. It makes them work together.
TWO PILLARS
Standard + Alliance
Technical orchestration meets ecosystem coordination
The Standard
Unified SSO with OIDC flow, standard app packaging format, centralized registry for discovery, common settings API for consistent UX. Publishers integrate once, users authenticate once.
Shared home screen, unified navigation bars, global app grid with search, cross-app command palette, integrated support system. Users navigate the platform, not individual apps.
Business object definitions (contacts, documents, tasks), cross-app event streaming, semantic knowledge graph, unified RAG/search APIs. Data flows between apps with context preserved.
Cross-service workspaces, threaded comments on any object, notification center aggregating all apps, shared presence and status. Collaboration transcends app boundaries.
Capability/intent casting (apps expose functions to platform), unified video conferencing, shared file picker, integrated image editing. Apps compose into workflows, AI agents orchestrate across tools.
Platform-level end-to-end encryption vault, granular permission models, audit logging, secure secret storage. Security is orchestrated, not fragmented across apps.
Flagship mobile app (iOS/Android) with embedded webviews, dedicated native apps for core tools, desktop client (Electron/Tauri), augmented browser extension. One platform, all devices.
The Alliance
A Manifesto
Open Buro exists to prevent European workplace fragmentation. Open source without orchestration creates chaos. We establish founding principles before code.
Open Governance
Neutral foundation structure modeled on Linux Foundation, CNCF. No single vendor controls the standard. Transparent decision-making, public roadmap.
Adoption Actions
Implementation support for publishers: reference architectures, migration guides, certification program. Alliance members don't just endorse—they implement.
International Visibility
European-scale promotion: conferences, government outreach, media relations. Make Open Buro the default assumption for workplace tech procurement.
Funding
Resource mobilization through member contributions, public grants (EU innovation funds), commercial services. Sustainable funding model ensures long-term viability.
"Code is Law... but Architecture is Politics"

FIRST IMPLEMENTATION
First Implementation in Twake.AI
Twake.AI is the first platform to integrate La Suite numérique components from DINUM, built on the Open Buro beta specification. It brings together messaging, videoconferencing, document editing, email, and more into a unified sovereign workplace.
The Twake Workplace dashboard — a unified interface orchestrating 15+ open source applications following the Open Buro standard.
