We offer a 30-day Free Trial version of Spider so that engineers can experience the software before making a purchase decision.

The Free Trial includes all of the core features of Spider. During the trial period, you can evaluate Spider on real projects, test its speed and accuracy, and ensure it meets your needs.

After 30 days, you can easily upgrade to a paid license (lifetime, 3-month, or 1-year) without losing your data or settings.

Completely reliable.

Out of thousands of users, only one has ever requested a refund — and that was because he was not a structural engineer.

You can be sure your investment is safe with us.

The answer is negative based on the following: When you purchase Spider, you are paying for 1.8 million lines of code, over 200,000 man-hours of engineering work, and more than 400 engineering functions — all covered by a lifetime license with support, upgrades, and maintenance by an experienced team.

The time you save using Spider usually pays back your investment within your first or second project.

With Spider, you can be confident that no part of your engineering responsibility is overlooked.

Spider’s pricing policy is based on the GDP of each country. Prices are adjusted so that engineers worldwide can afford the software.

In wealthier countries, higher prices contribute to the further development of Spider, while engineers in lower-GDP countries benefit from reduced pricing. This way, everyone wins.

If you are familiar with structural engineering and software such as ETABS, SAP2000, or SAFE, Spider will be easy for you.

We provide step-by-step instructions, a comprehensive user manual, and sample files to help you get started.

Since Spider runs inside AutoCAD, it is subject to AutoCAD’s memory and processor management limits.

For best performance and reliability, we recommend using Spider for mid-rise structures rather than extremely large or high-rise buildings.

This ensures smoother operation, faster processing, and more efficient use of your system resources.

When you buy Spider, you agree to use the software legally and ethically within the country of purchase.

From a technical perspective, it is also not possible to use Spider in a country different from where it was purchased, unless a special exemption is granted.
