We believe anyone should be able to run simple, low-volume workflows at no cost, sharing their workflows with the public so everyone benefits from the work of others. We also want to foster a positive community where people feel good about sharing their work and where everyone can learn from one another. In the future, we may offer features available on paid tiers which would be logical enterprise features such as single sign on (SSO), team collaboration and higher SLAs and throughput.

The constraints are listed in our docs - https://docs.pipedream.com/pricing/
