SSISOFT is an engineering software company founded in 2008, primarily serving engineers, researchers, and technical professionals with tools for structural analysis, foundation design, and technical calculations. Its flagship product, KCW, was first released in 2000 and has been continuously updated since then. It is positioned as software for structural analysis and engineering calculations. The company also offers DFD for pile foundation design and SFD for shallow foundation design.
Based on the publicly available content, KCW covers the basic workflow of structural analysis: rapid modeling, load management, linear analysis, internal force diagrams, design checks, engineering reports, as well as 3D models, deformed shapes, and result visualization. DFD focuses on pile foundations, supporting axial bearing capacity, pile group evaluation, settlement checks, and design summaries. SFD is used for shallow foundation design, including bearing capacity and settlement assessment, stability checks, and design output. Overall, these products are more like traditional civil engineering desktop software than a general-purpose development framework or cloud development platform.
Pricing is relatively clear: both DFD and SFD are free to use with no time limit. KCW offers both perpetual licenses and subscriptions. The perpetual hardware-lock license costs USD 999, requires a USB hard key, and includes free updates for the first 3 years. The subscription version uses a soft key/online registration model, priced at USD 400 for 1 year, USD 250 for 6 months, and USD 150 for 3 months. For short-term projects, the short subscription plans are more flexible; long-term teams can compare them against the cost of a perpetual license.
The advantages are its focused use cases, transparent pricing, and the fact that two foundation design tools are free, making it easier for engineers to get started at a low cost. KCW covers modeling, analysis, design checks, reporting, and visualization, offering a relatively complete workflow. The downsides are that the website does not specify supported operating systems, design codes, input/output formats, API/SDK availability, third-party integrations, documentation/manuals, or technical support channels. The hardware-lock licensing model may also be inconvenient for remote work, cloud desktops, or centralized IT management.
It is suitable for engineers, small design teams, and teaching/research scenarios involving structural analysis, pile foundation design, and shallow foundation design. If a team needs clear support for local design codes, BIM/CAD integration, batch automation APIs, or enterprise-level support, it should confirm these details with the vendor first.
