Common Questions
Why is it free right now?
We are a startup based in Kerala. We want to get Griham into the hands of as many site engineers as possible to perfect our engines. While in open beta, all current features are 100% free.
Will I be forced to pay later?
No. The Basic tier will remain free forever. When Pro officially launches, you can choose to upgrade for advanced cloud features, or seamlessly stay on Basic.
Can I request a specific calculator?
Yes. Pro users will have access to our Custom Formula builder, but you can email our dev team right now to request permanent additions to the main library.
