So, how does SkyCiv compare?

Reasons why SkyCiv stands out.

Enercalc Alternative

Enercalc offers a range of design modules for specific calculations. This collection of calculations provides a mix of analysis/design calculations.

The software is install-download and mostly based on spreadsheets. Enercalc has more specific design calculations, but the user experience leaves a lot to be desired. Good for component design, but not as strong in analysis, modeling, and graphics.

SkyCiv offers the core design requirements of Enercalc, with a faster, easier, and online interface. All of the SkyCiv products are fully integrated, so going from analysis to design is a seamless process

SkyCiv Strengths

  • Monthly Subscriptions
  • Live Chat Software Support
  • Powerful FEA with Clean Interface and Graphics
  • Easier to Learn and Use
  • No Download/Installation Necessary
  • Integrated Design Modules
  • Includes a Mobile App for Beam Calculations, Section Database and more...

Microstran Alternative

Multiframe is a Bentley-owned product that has been in the market for over 30 years. It's a frame analysis software with design capabilities (mainly focused on AS and US). It has similar graphics, modeling, and design capabilities to an older desktop interface.

The product has a slower development cycle, with the last update in May 2020. SkyCiv's software is updated on a weekly basis, with new features, bug fixes, and products being actively released based on user feedback.

SkyCiv also has active and responsive customer support. Via our live chat, customer questions are usually addressed and resolved in a couple of hours (if not minutes!). This helps engineers move forward on projects without software-related delays.

SkyCiv Strengths

  • Active, Regular Product Updates
  • Nothing to Download
  • Cleaner and Easier User Interface
  • No Download/Installation Necessary
  • Simple Monthly Subscription Licensing
  • Includes a Mobile App for Beam Calculations, Section Database and more...

Spacegass Alternative

Spacegass is a predominately Australian product that offers frame analysis and design capabilities. It also has similar graphics, modeling, and design capabilities to an older desktop interface. SkyCiv's analysis and design capabilities go beyond Spacegass and are being actively developed and improved on a weekly basis.

SkyCiv also offers flexible, monthly pricing and is a lot more affordable with no large upfront cost associated with the product.
