Looking for a Sparx Systems Enterprise Architect alternative?
What is the best alternative to the legacy UML modeling tool? Discover the benefits of Boldo for companies seeking agility and collaboration.
From technical engineering to collective intelligence

Sparx Systems Enterprise Architect
For two decades, Sparx Systems Enterprise Architect has been an essential reference for system and software modeling (UML, SysML). Its functional depth and attractive licensing costs have made it the standard for engineers and technical architects. However, this exhaustiveness results in an austere, 'bloated' interface and a steep learning curve, creating an insurmountable barrier for business stakeholders and non-technical decision-makers.
Boldo reinvents enterprise architecture by moving it out of pure technical territory and turning it into a strategic dialogue tool. Thanks to a 'Consumer Grade' user experience and a 100% web-based approach, the platform allows you to map, visualize, and share enterprise knowledge without the need for extensive training. Boldo thus transforms complex repositories into understandable narratives for the entire organization.
Adopt ergonomics designed for widespread adoption
While Sparx Enterprise Architect offers unmatched technical depth for software engineers, its complex interface and overloaded menus quickly discourage occasional users. The tool often remains confined to a small circle of experts, unintentionally creating knowledge silos inaccessible to the rest of the company.
Boldo removes this barrier by offering a sleek and intuitive interface inspired by the best consumer tools. The No-Code approach allows any collaborator to navigate the architecture and contribute to documentation without prior training, ensuring broad and sustainable adoption across teams.

Move from local modeling to real-time collaboration
While Sparx allows teamwork, it often requires complex setups of shared SQL databases or third-party services (Prolaborate). Historically, the model relies on 'Check-in / Check-out' logic, creating version conflicts and hindering fluid communication between architects.
Conversely, Boldo is a natively collaborative SaaS platform. Multiple users can work on the same views simultaneously, with a system of contextual comments and mentions (@). Boldo streamlines interactions and ensures that the data presented is always up-to-date and synchronized for all stakeholders.

Transform your diagrams into communication tools
Rooted in engineering logic, Sparx excels at producing static technical diagrams for project documentation. However, transforming these models into presentation materials for the Executive Committee requires considerable effort, as the tool lacks simplification or storytelling features for non-expert audiences.
Boldo allows you to instantly transform architecture data into dynamic and scripted views. Thanks to its storytelling features, architects can guide decision-makers through IT evolutions, presenting impacts and transformation scenarios in a visual and educational manner.

Designed for collaboration across all stakeholders
Architecture should not live in silos. With Boldo, business teams, IT and leadership work on the same views, in a shared and living workspace. Everyone explores, comments and aligns in real time. Architecture becomes a collective alignment tool, directly understood and adopted across the organization.

Built on European data sovereignty
Boldo is a French platform, with data hosted in Europe on Scaleway, a trusted sovereign cloud infrastructure. Your architecture repository stays fully under your control, in an environment designed to meet regulatory requirements. No ambiguity, no hidden dependencies: clear hosting, clear rules, full transparency.

A flexible metamodel that adapts to your reality
Every organization has its own constraints and maturity. Boldo relies on a flexible and evolving metamodel that adapts to your context instead of forcing a rigid framework. Start simple, enrich progressively, and let your architecture evolve at your own pace.

Visual storytelling at the core of the experience
In Boldo, diagramming is not an afterthought, it's the heart of the product. Views are intuitive, visually refined and immediately readable. Clear hierarchies, smooth navigation and embedded diagrams make architecture easy to grasp and easy to share, from executive committees to hands-on workshops.

Fair and transparent pricing
Boldo offers Pro and Team plans in self-service, with public and predictable per-user pricing. No opaque licenses, no hidden bundles, no constant renegotiation. From day one, you know what you pay, what you get, and how it scales.

We are here to drive adoption and value
Customer Success is central to our approach. We work closely with teams to build an architecture governance that is useful, alive and truly adopted. Responsive support, continuous exchanges and a long-term vision ensure architecture becomes a concrete decision-making asset, not a theoretical exercise.
