Archilu vs Orbus: Sovereign, Transparent EA vs a Microsoft-Stack Suite

Operating model deep dive

Enterprise architecture software only creates value when it improves how decisions are made across strategy, portfolio, and delivery.

Before selecting a platform, define who makes which architecture decisions, what evidence is required, and how exceptions are tracked to closure.

• Map decision workflows by role (EA, domain leads, product, security, finance)
• Define minimal evidence pack for each decision type
• Set escalation path when standards and delivery pressure conflict

Two different bets: Microsoft-stack fit vs EU sovereignty

OrbusInfinity is a well-established enterprise architecture platform, named a Leader in the Gartner Magic Quadrant for EA Tools 2025. Its distinctive positioning is a tight fit with the Microsoft ecosystem: integration with Microsoft 365 and tools like Visio, plus freely available starter templates, including TOGAF and Visio content. In late 2024 it expanded by acquiring Capsifi, adding business-architecture capability to its offering.

Archilu makes a different bet: a focused model, transparent pricing, EU sovereignty and fast time-to-value. This comparison is honest about where each one leads, and it does not pretend Orbus's Microsoft-stack strength away.

Pricing: published vs on-quote

The clearest commercial difference is transparency. Archilu lists its plans publicly with unlimited users, so a team can estimate cost before engaging sales.

OrbusInfinity is priced on quote with no standard public list; any figure you find online is a third-party estimate negotiated per deal. For procurement that needs defensible, predictable budgeting, that is a structural advantage for Archilu.

• Archilu: 1,290 EUR/month Essential, 2,500 EUR/month Professional, Enterprise on quote — unlimited users
• Orbus: pricing on quote (no standard public list; any figure is an estimate)

Microsoft 365 integration vs vendor neutrality

Orbus's Microsoft-centric design is a genuine asset for organizations standardized on M365. Native integration with Visio and the Office ecosystem can lower the entry barrier for teams that already model in those tools, and the free TOGAF and Visio templates are a real, public on-ramp.

Archilu is deliberately not coupled to a single productivity suite. If your environment is mixed, or if you prefer a tool whose value does not depend on a particular vendor's ecosystem, that neutrality matters. Neither posture is wrong — the question is which one reduces friction for your teams.

Sovereignty, language and regulated finance

Archilu offers EU or on-premise hosting you control, is natively bilingual French and English, and is built around DORA/CSSF documentation and governance needs — relevant across Luxembourg, Belgium, France and Switzerland.

Orbus is a broad, English-first international platform. The question is whether native French, guaranteed EU residency and a regulation-first design reduce friction for your teams and auditors — particularly when the repository describes your critical functions and ICT dependencies.

Where Orbus is the stronger choice

We say it plainly: Orbus carries Gartner Leader recognition, deep Microsoft 365 integration, a Visio-based modeling heritage and, since the Capsifi acquisition, broader business-architecture capability. If your organization is standardized on Microsoft tooling or your procurement mandates an established, ecosystem-integrated vendor, Orbus's depth is a genuine advantage.

Archilu trades that ecosystem coupling for transparency, sovereignty and time-to-value. The decision guide below summarizes when each one fits.

Decide from your maturity, not a feature grid

Rather than choose on a feature grid alone, start from where your architecture practice actually stands. Archilu's free EA Maturity Assessment scores ten dimensions and returns a prioritized action plan in about ten minutes — a fast, concrete way to see which platform profile your organization really needs.

Metrics that matter

Use KPIs that measure decision quality and adoption, not tool activity volume.

• Decision lead time by workflow
• Adoption rate by role and business domain
• Architecture exception closure rate
• Portfolio decisions supported by evidence

Common mistakes

Most software selection failures are operating model failures before they are tooling failures.

• Comparing feature lists without testing real decision workflows
• Ignoring integration and data model constraints
• No adoption plan by stakeholder group
• No migration strategy for existing repositories
