Custom diagram tools for software architecture

Improve your software architecture dia gram tool's performance, clarity, and usability with our custom design and development service.

Does your software architecture product hold you back?

We understand the frustrations tied to off-the-shelf software architecture tools and in-house diagram apps – and we know how to approach them.

Off-the-shelf tools with poor fit
Off-the-shelf tools with poor fit

Tools like Lucidchart, FigJam, or Miro lack proper architectural notations, validation capabilities, and customization, forcing workarounds that compromise productivity.

Complexity that creates confusion
Complexity that creates confusion

Large systems quickly become visual chaos with crossing lines, overlapping elements, and no way to filter or organize information effectively.

Performance issues

FAQ

  • Will the tool allow me to create interactive software architecture diagrams?

    Yes, we can build your solution with fully interactive diagrams where elements can be explored, edited, and manipulated in real time. This makes it easier to communicate system designs and collaborate effectively across teams.

  • Will the tool let me work on different levels of detail (e.g., high-level and low-level architecture)?

    Yes, we can design your solution to support multiple layers and levels of detail, so you can move easily between high-level views and more granular architecture diagrams. This flexibility ensures the tool reflects how your teams actually design and maintain systems.

  • What modeling standards will the tool support (C4, UML, DDD, others)?

    We can implement support for the modeling standards your organization relies on, whether that’s C4, UML, DDD, or other notations. The solution is built around your specific workflows, so your teams can work with familiar structures and methods.

  • Will the tool let my team collaborate on diagrams in real time?

    Yes, we can equip your solution with real-time collaboration features, including simultaneous editing and role-based permissions. This way, distributed teams can work together smoothly without conflicts or delays.

  • What systems and tools will the solution integrate with? Will there be an API available?

    We can design the solution to integrate with your existing development environment, documentation tools, or monitoring systems. An API can also be included to enable automated updates and seamless data exchange across platforms.

  • Can the solution be deployed on-premise, or will it work only in the cloud?

    You can choose the deployment model that best fits your organization. We can build the solution for secure on-premise use, cloud deployment, or a hybrid setup depending on your infrastructure and compliance requirements.

  • Will it be possible to extend the solution with additional modules or integrations in the future?

    Yes, we design the solution with scalability in mind, so new modules, features, or integrations can be added as your needs evolve. Whether ongoing development stays with us or is handed over to your team, the product is built to remain easy to extend and maintain.

  • What does the implementation process look like, and what kind of support will I receive afterwards?

    We start with discovery and design workshops, followed by development tailored to your goals. The code is then handed over to your team, and we support you during the implementation phase. You’ll also receive detailed documentation, training, and flexible support options – including SLAs and dedicated assistance – for a smooth handover and long-term reliability.
