OpenProject vs Microsoft Project

Why Switch from Microsoft Project to OpenProject?

Microsoft Project remains the reference for traditional project management at large enterprises. For European organisations — particularly those in the German Mittelstand, public sector, construction, and regulated industries — the structural concerns are familiar: Microsoft Project is a US-headquartered product, your project plans live on Microsoft infrastructure under US legal jurisdiction, and the licensing economics scale aggressively at enterprise tiers.

OpenProject is the German open-source alternative. Full feature parity for most PM use cases, EU jurisdiction, self-hostable for maximum sovereignty, with strong adoption across German federal and Länder governments, infrastructure operators, and Mittelstand companies.

For European traditional PM use cases, OpenProject is structurally competitive.

Pricing

OpenProject pricing options:

• Community Edition: Free forever (GPLv3) — self-host, full PM functionality
• OpenProject Cloud: €7.25/user/month — EU-hosted by OpenProject GmbH
• OpenProject Enterprise (on-premise): €7.25/user/month — self-hosted with Enterprise features
• BIM Edition: additional pricing for construction-specific bundle

Microsoft Project pricing:

• Project Plan 1: $10/user/month — basic
• Project Plan 3: $30/user/month — desktop client included
• Project Plan 5: $55/user/month — portfolio management

For a typical 50-person team needing portfolio capability, OpenProject Enterprise at €4,350/year vs MS Project Plan 5 at $33,000/year is a material difference.

Privacy & Data Sovereignty

OpenProject’s structural advantages:

• German corporate jurisdiction — OpenProject GmbH subject to German and EU law
• EU data centres for OpenProject Cloud (Germany)
• GDPR-native with Article 28 DPA
• Self-host option for full data sovereignty
• Open-source codebase auditable on GitHub
• No US legal exposure at any layer

For German public-sector buyers, the combination of EU jurisdiction + on-premise option + open-source code makes OpenProject the default rather than the exception.

Migration Guide

Moving from MS Project to OpenProject:

1. Set up OpenProject — Community Edition self-host, or OpenProject Cloud account (1 hour - 1 day)
2. Configure project structure — work packages, types, statuses to match your MS Project conventions (2-4 hours)
3. Import MS Project files (.mpp) — OpenProject imports tasks, dependencies, durations, resources (15 min per project file)
4. Reconstruct custom fields — if you use MS Project custom fields heavily, expect manual mapping (1-3 hours per project)
5. Set up team accounts and project memberships (1-2 hours)
6. Configure reporting and dashboards (2-4 hours)
7. Train team on OpenProject interface (half-day session)
8. Parallel-run with MS Project for 2-4 weeks (operational)
9. Decommission MS Project at next renewal

Estimated total time: 1-2 weeks for a 50-person organisation; significantly longer for large enterprise MS Project deployments with custom infrastructure. Difficulty: Moderate; primary complexity is workflow reconstruction and team training.

Real-World Use Cases

A German federal agency uses self-hosted OpenProject Community for cross-departmental project coordination. The on-premise deployment is mandatory under their data sovereignty requirements; OpenProject’s German jurisdiction and open-source nature made it the natural choice.

A Munich engineering consultancy moved from MS Project to OpenProject BIM Edition. The native BIM integration replaced expensive specialised tools; annual licensing costs dropped by approximately €25,000 across their 40-person team.

A Swiss construction company uses OpenProject for project portfolio management across multiple concurrent infrastructure projects. The combination of Gantt-based planning, BIM integration, and EU/Swiss jurisdiction matched their procurement requirements.

Company Background

OpenProject GmbH is a Berlin-based German company developing and operating the OpenProject open-source PM platform. The project began as a fork of ChiliProject in 2010 and has been actively developed since. OpenProject GmbH was founded to provide commercial support, managed hosting, and Enterprise features while maintaining the open-source Community Edition.

As of 2026, OpenProject serves significant deployments in German federal agencies, Deutsche Bahn, multiple German Länder governments, EU institutions, and thousands of SMB and enterprise customers across Europe. The company has been consistently profitable and product-focused.

Security & Compliance

• GPLv3 open-source licence
• ISO 27001 aligned
• BSI C5 alignment for German public-sector buyers
• GDPR-native with Article 28 DPA
• TLS 1.3 in transit, AES-256 at rest
• SSO/SAML support
• Audit logs with retention policies
• NIS2-aligned for essential entities

Integration Ecosystem

• Nextcloud integration (German EU stack pattern)
• GitHub / GitLab integration for code-aware project tracking
• Slack, Microsoft Teams, Element notifications
• OneDrive, Nextcloud, S3 for document attachments
• LDAP / Active Directory for enterprise auth
• API: comprehensive REST API + webhooks
• CalDAV for calendar sync
• BIM: IFC standard for construction integration

Who Should Switch?

OpenProject is ideal for:

• German public-sector and Mittelstand organisations
• European construction and engineering firms (BIM integration)
• Regulated industries needing on-premise deployment
• Organisations migrating off MS Project for cost or sovereignty reasons
• Open-source advocates wanting auditable PM software

The Bottom Line

Microsoft Project remains the dominant tool for large enterprises deeply embedded in the Microsoft ecosystem. For European organisations — particularly German public sector, construction, engineering, and Mittelstand — OpenProject is the better choice: comparable feature set, dramatically lower cost, EU jurisdiction, on-premise option, and an open-source codebase that no future business decision can take away.

Frequently Asked Questions

What's the difference between Community and Enterprise editions?

Community Edition is the free open-source version under GPLv3 — fully functional for core PM use cases including Gantt, agile boards, time tracking, and team collaboration. Enterprise Edition adds enterprise features (project portfolio management dashboards, custom themes, advanced reporting, BIM integration, premium support) and is licensed per user. Both options share the same core codebase.

Where is the cloud version hosted?

OpenProject Cloud is hosted in EU data centres operated by OpenProject GmbH (Germany). OpenProject GmbH is a German company subject to German and EU law — no US legal exposure. For maximum sovereignty, self-host OpenProject on your own infrastructure.

Can I migrate from Microsoft Project?

Yes. OpenProject imports MS Project files (.mpp) directly. The import preserves task structures, dependencies, durations, and resource assignments. For complex MS Project Pro deployments with custom fields and macros, plan for additional manual reconstruction. Most SMB migrations complete within a week.

How does OpenProject compare to Jira and Asana?

Different positioning. Jira is the dominant agile-software-development tool. Asana is more lightweight collaborative work management. OpenProject is closer to traditional PM (Gantt, dependencies, resource planning) with EU jurisdiction. For software teams in pure agile, Jira often wins. For mixed environments — construction, engineering, government, traditional project work — OpenProject's classic PM features matter more.

Is BIM integration really included?

Yes. OpenProject has native BIM (Building Information Modeling) integration via the OpenProject BIM Edition. This is significant for construction and engineering project management — typically requiring expensive specialised tools elsewhere. BIM integration is one of OpenProject's structural differentiators in the German construction and infrastructure markets.
