Unleash Reviews & Product Details

I find Unleash's easy setup both from an integration standpoint (code) and a non-technical UI very beneficial. This allows more exposure to people in the business, letting them tweak things without needing engineering expertise. I appreciate that picking up where we left off with Unleash, after prioritization shifts, was simple and quickly showed us the benefits. Unleash provides a straightforward interface with insightful information that many roles in the business will be keen to use. The quick setup tutorial helped us see it working in a short amount of time, and there are plenty of SDK options that suited our needs. I also like that Unleash allows us to kill a switch instantly when issues arise without needing to deploy, test, or lean on business resources, and it provides an easy way to handle rollouts in various ways.

Understanding segments and constraints has been a bit of a task as we switch to using this terminology. We were also surprised to not be able to use SSO without switching to a paywall. Review collected by and hosted on G2.com.

I believe Unleash makes feature toggling better managed and easier to use, especially for people who don’t have a technical background. Review collected by and hosted on G2.com.

Unleash should introduce more consumer-friendly pricing packages, such as a viewer-access-only option. Right now, users still have to pay the full seat price even when they don’t use many of its features. Review collected by and hosted on G2.com.

I love that Unleash is open source, easy to try before you buy, and provides all the advanced capabilities we need—like advanced rollout strategies, real-time governance, SDKs for every stack, and especially detailed metrics for feature flag exposure. It freed our engineers from maintaining in-house tools, letting us focus on delivering value to customers faster. The support and Slack community are also excellent, providing quick answers and valuable insights. Review collected by and hosted on G2.com.

Honestly, there isn't much to dislike. Our in-house solution worked, but maintaining and evolving it was a drain on engineering resources. With Unleash, we no longer waste time reinventing the wheel or struggling with limited capabilities and lack of documentation. If anything, I would say that for very simple scenarios, building your own might seem cheaper, but for complex use cases like ours, Unleash is much more efficient.

I love how Unleash enables us to manage feature flags and experiments seamlessly across multiple languages and environments. Its API-first approach let us automate provisioning and configuration, while the built-in support for multi-tenancy and constraints makes it ideal for our complex microservice architecture. The ability to extract experimentation data into our warehouse and the robust SDKs across languages have been game-changers for developer productivity and reliability.

At times, running multiple on-prem Unleash instances added operational overhead, especially as our architecture scaled and matured. Migrating to Unleash Cloud presents some challenges, particularly in consolidating environments and ensuring smooth service continuity, but we're optimistic about the benefits this change will bring.

I love how Unleash has brought us stability, scalability, and confidence at Wayfair. The switch from our in-house tool to Unleash solved our scalability and maintenance headaches, and features like Edge, segmentation, and the Admin UI have been game changers. We can now experiment and roll out features safely, recover instantly from issues, and manage thousands of feature flags with ease. The cost savings and reduction in engineering overhead have been huge, and the platform's observability and governance features are essential at our scale. Review collected by and hosted on G2.com.

Initially, we had to use a one-size-fits-all strategy for configuring Unleash, which led to some bottlenecks when all services queried the main server directly. However, adopting Unleash Edge quickly resolved those issues for us. We're also looking forward to leveraging new features like milestones in version 7, which aren't available yet in our current version. Review collected by and hosted on G2.com.

Feature on/off when deploCentrally manage feature flags (feature toggles) to instantly turn features on/off without deployment. Review collected by and hosted on G2.com.

The per-user subscription price is too high for the features it provides. Review collected by and hosted on G2.com.

I appreciate Unleash's enterprise-grade security, particularly its fine-grained role-based access control and seamless SAML integration with our corporate LDAP. Its context-aware, dynamic feature toggles enable fast experimentation and safe rollouts. The broad agent support across our complex technology stack, including proxies for single-page applications, made integration smooth. The ability to combine multiple rollout strategies, such as IP-based filtering and A/B testing, has been invaluable. Unleash has allowed us to decouple deployments, perform surgical rollbacks, and scale feature delivery intelligently, enhancing our innovation speed and confidence.

None so far after using it for 3+ years and rolling it out for multiple teams. Review collected by and hosted on G2.com.

I appreciate that Unleash also offers an open-source variant that we can run locally, especially in the development environment. It is helpful that the developers have Unleash directly locally and can test everything with it. Additionally, the initial setup was generally very easy, apart from a few specific adjustments we had to make. Review collected by and hosted on G2.com.

Nothing, we are completely happy Review collected by and hosted on G2.com.

We’ve been using the open-source self-hosted version of Unleash for over three years. Before that, we had a very simple in-house solution with many limitations. When searching for a more robust alternative to support our growth, Unleash stood out among the options. The best part is how it allows us to manage dozens of feature flags in a fast and simple way, enabling over 15 tech teams to work independently while implementing their own release strategies. Review collected by and hosted on G2.com.

The main limitation we face today with the open-source version is the inability to create multiple projects to organize and separate our feature flags. This makes it harder to scale the setup as our teams and number of flags grow. Review collected by and hosted on G2.com.

I love how Unleash empowers us to manage feature flags and experimentation across a complex, multi-tenant architecture with multiple programming languages. The API-first approach, robust SDKs for different languages, and the ability to standardize feature flag usage have made it easy for our developers to adopt. It's been especially valuable for running A-B tests, integrating analytics, and safely rolling out or fine-tuning models in production. The move to Unleash Cloud promises to simplify maintenance and centralize our management, which I'm excited about. Review collected by and hosted on G2.com.

One challenge we've encountered is the overhead of managing multiple on-prem Unleash instances, especially before features like progressive constraints were available. Migrating to Unleash Cloud requires careful planning and some custom tooling to ensure a smooth transition without disrupting existing services. While these aren't deal-breakers, they do add some complexity to our workflow. Review collected by and hosted on G2.com.
