Frequently Asked Questions FAQs

We lowered the operating cost of e-signing to the floor by leveraging revolutionary AWS serverless computing architecture. It costs us less than $1 to process 1000 document signings. (In AWS speak, a 128-MB Lambda costs $0.0000000021 per millisecond.) Combined with some advertising revenue, RabbitSign is free and profitable.

We may create a paid tier for new users in the future. However, if you already have a RabbitSign account, whatever you are using for free today will remain free for you forever.

When the COVID-19 pandemic made e-signing essential, we were disappointed that no existing e-signing providers responded with a generous free offering. So we decided to make one that is unlimited free.
