There can be advantages to have a limited free plan. I offer limited free plans for 2 main reasons: * users can make sure they like the service before paying for it. This avoids costly refunds * users can integrate our API and doing tests without having to pay for it. It makes for a better experience, as they don't feel they are paying for missing documentation or limited libraries. If you make the free plan useful as a trial, this can be a win-win. With my service, I see people using the free plan as a trial only: after a few days they pay for it, or they stop using the service. I also use my free users for posting Tweets and other social sharing.
