# In-House vs. Commercial System Simulation Tools
> For decades, ambitious engineering teams have developed system simulation tools themselves. While “in-house tools” offer advantages once they’re de-bugged and deployed, development costs quickly add up. It's helpful to compare in-house tools vs. commercial tools to ensure the best outcome for your organization.

The new eBook, ‘In-House vs. Commercial Tools - Trade-offs and Opportunities’, explores the costs of development and capabilities of different tools.

In-house tools are a mainstay for system engineers. Built with accessible coding languages such as FORTRAN or MATLAB, these tools are custom-built to describe the systems that make each organization unique. For decades, they’ve been thought to be the most accurate and cost-effective tools for enabling system design, simulation, and optimization. But is that still the case?

In this eBook, we discuss how the benefits of in-house tools stack up with the benefits of commercial tools such as Modelon Impact. From case studies of industrial companies replacing their in-house tools to cost comparisons over time, you’ll find that commercial tools may offer advantages for your team.
