Is the price for Spider high?

Absolutely no.

Please consider that you pay this amount for 1.8 million lines of code, 200.000 man-hours of work, and more than 400 engineering acts and functions for a lifetime license and its support, upgrade, and maintenance by an experienced team of engineers.

In addition, the time that this software saves returns your investment in the first or second project you work with Spider.

Furthermore, when you work with Spider you are sure that no part of your engineering responsibility is missed.

Why does the Spider price change in different countries?

The pricing policy for Spider is based on the GDP of the countries. Different countries have different GDPs and we set the price in a way that all engineers around the world could buy the Spider. On the other hand, the higher prices for richer countries would raise funds to develop Spider and the company. Based on this pricing policy, all of you in different countries would be winners.

We have heard that a cracked version of Spider exists in the market. Is this true?

Absolutely no.

After 20 years of presence in the market, no cracked version of Spider exists and with newly implemented technologies, actually, it’s not possible.

So, invest with confidence and complete your purchase. Reciprocally we invest your money in serving you better.

How reliable is your Money Back Guarantee policy?

Absolutely reliable with no question,

For your information from the thousands of users we have, only one of them returned his software during our MBG period which we returned the respected client's money with no question. He returned Spider because he was not a structural engineer.

Everyone who works with Spider would love it.

Is that hard to work with Spider?

If youre a structural engineer who is familiar with engineering terms and software environments like ETABS, SAP2000, or SAFE, working with Spider is really easy for you.

We have step-by-step instructions on how to use the software and a very well-developed manual. Please start Spider with the sample files we send you along with the installation link.

Furthermore, videos on the SPIDTECH YouTube channel can help in better understanding Spider.
