The Platform Effect Gap
Open source apps work — individually. But dominant suites win because they feel like one product: shared context, seamless workflows, unified experience. Individual excellence doesn't beat ecosystem cohesion.
Unifying open source workplace apps into a true platform alternative to Microsoft 365
Europe now has serious open source workplace tools — email, docs, project management, video, chat. They're mature, deployable, and increasingly adopted. Yet dependency on dominant suites keeps growing.
Why? Not because the alternatives are bad — but because Microsoft and Google have something more: the platform effect.
What's missing isn't better apps — it's the orchestration layer between them.
Open source apps work — individually. But dominant suites win because they feel like one product: shared context, seamless workflows, unified experience. Individual excellence doesn't beat ecosystem cohesion.
A single login across multiple tools sounds like progress — but it only produces an app catalog behind one door. What's missing is the orchestration layer: identity, rights, notifications, documents and workflows circulating between services.
The lock-in isn't just budgetary — it's political. Roadmaps, integrations, and platform orientations are decided outside Europe, durably structuring organizations that have no seat at the table. Sovereignty requires infrastructure, not just intentions.
Open Buro orchestrates existing apps into a cohesive platform—no vendor lock-in, no rip-and-replace.
Standard app format. One registry. Any publisher can contribute.
Common home, unified app grid, global search. Users never lost.
Business objects flow between apps. Semantic graph connects knowledge.
Organization-wide groups, permissions, presence. Manage once, apply everywhere.
Open Buro doesn't replace your apps. It makes them work together.
Technical orchestration meets ecosystem coordination
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.
Open Buro exists to prevent European workplace fragmentation. Open source without orchestration creates chaos. We establish founding principles before code.
Neutral foundation structure modeled on Linux Foundation, CNCF. No single vendor controls the standard. Transparent decision-making, public roadmap.
Implementation support for publishers: reference architectures, migration guides, certification program. Alliance members don't just endorse—they implement.
European-scale promotion: conferences, government outreach, media relations. Make Open Buro the default assumption for workplace tech procurement.
Resource mobilization through member contributions, public grants (EU innovation funds), commercial services. Sustainable funding model ensures long-term viability.
