Why free? Because renting a signature box month after month is silly.
I built SigFetch because I needed to do e-signatures several times, but didn't want to sign up for a monthly subscription for something I need once-a-year. Would I tip a couple bucks to get it done? Sure. Should I pay $15.99/month to keep track of one rental contract and a waiver form? No. That's why SigFetch was born.
So SigFetch is free for everyone. Not a free tier with a counter in the corner, waiting for a moment to pounce. The product, including the API for devs, is free, with no document limits, no upsell, and no surprise recurring charge that shows up on your monthly credit card statement.
What it costs to run
Well, it's not free to run. There is hosting, services, administration, and a variety of other charges I pay for every month. My hope is that by providing a good service, you'll donate to keep it going for others, just like you'd tip an Uber driver for a good ride. If everyone does a little bit when they can, we can keep it going.
Lots of software used to work this way. It was called freeware or shareware. SigFetch is embracing that model on the belief that if good people get good service, they'll chip in. If SigFetch saves you some time and money, and you can, then throw us a bone. If it doesn't, or you can't, then use it anyway.
There's no gimmick. There's no limited free version. The whole thing is free.
Signing up takes about a minute, you'll be sending docs in two. Every feature is live and waiting for you to try.
