# Unleash OSS and Unleash Enterprise comparison
> Compare Unleash Open Source and Unleash Enterprise features, including core feature management, governance, security, observability, and hosting options.
Unleash offers both an open-source (OSS) version and an Enterprise version.
[Unleash OSS](https://github.com/Unleash/unleash) is a great way to explore Unleash and experiment with feature flags. It gives you the core feature set of Unleash, but is designed for small-scale deployments with a limited number of server instances and direct SDK connections.
For production workloads, we recommend [Unleash Enterprise](https://www.getunleash.io/pricing). With our Enterprise plans, you have access to the full feature set, including higher resource limits, advanced governance, automation, observability, integrations for identity and compliance, and access to [Unleash Edge](/unleash-edge) for scalable SDK traffic.
Unleash Enterprise is suitable regardless of your team size, from small teams just getting started to large organizations running feature flags across thousands of services. It is designed to scale with you so you only pay for what you need, with flexible plan options from monthly pay-as-you-go to annual contracts, and flexible deployment options from [self-hosted](/guides/scaling-unleash#self-hosting-unleash-designing-for-high-availability) to [hybrid](/guides/scaling-unleash#choosing-the-right-deployment-option) to fully managed cloud.
This page highlights the key differences between Unleash OSS and Unleash Enterprise.
