What do you like best about Unleash?

Unleash has made our release process much more flexible. Feature flags let us deploy changes safely and roll out features gradually. It has become one of the most essential tools in our development, testing, and release workflow. It is now a part of our daily operations.

The Python and React SDKs integrated smoothly into our code and tests.

The Unleash UI is intuitive and provides all the necessary tools to manage the entire feature flag lifecycle, from creation to cleanup.

The service has been reliable with excellent uptime, and the support team checks in proactively, even though we have not had issues.

Unleash does exactly what we need. It is a simple and reliable feature flag management solution. Review collected by and hosted on G2.com.

What do you dislike about Unleash?

I don’t have any major complaints, but if I had to mention something, I’d love more advanced querying capabilities, potentially supported by AI-driven insights. Review collected by and hosted on G2.com.

What problems is Unleash solving and how is that benefiting you?

Unleash solves the problem of having to change configuration values or redeploy services every time we need to enable or disable a feature. Instead, we can manage feature flags in real time, making it much easier to control and deploy changes without requiring a full deployment cycle. This flexibility allows us to react quickly to customer feedback and make gradual changes without interrupting the system.

Additionally, Unleash simplifies monitoring feature flag states across all our customers and gives us the ability to define advanced conditions for how flags behave. This ensures better control and fine-tuning of our features, benefiting both our internal teams and end-users. Review collected by and hosted on G2.com.

What do you like best about Unleash?

Unleash was beneficial in these 6 key areas for our team:

1. Reduced release anxiety: By making it easier to roll back changes, it took the pressure off release days.

2. Minimized downtime: This was a key improvement for our stakeholders.

3. Improved our codebase: Unleash gave us the breathing room to refactor and upgrade our aging Java codebase.

4. Gained confidence in releases: Both our team and stakeholders felt more secure with the release process.

5. Decoupled front-end and API development: By putting API features behind feature flags, we could develop and deploy API features independantly of when front-end changes could be made.

6. Self-hosted offering: This made it easy and low cost to evaluate Unleash. Review collected by and hosted on G2.com.

What do you dislike about Unleash?

There wasn't a good path to migrate from the self-hosted option to a paid option hosted by Unleash without starting from scratch with feature flags. Review collected by and hosted on G2.com.

What problems is Unleash solving and how is that benefiting you?

Unleash reduced our release anxiety, minimized our release downtime due to rollbacks, assisted us in improving our codebase, and helped stakeholders gain confidence in our releases. Review collected by and hosted on G2.com.

What do you like best about Unleash?

Unleash is an exceptional service that has truly transformed our release management process. Its user-friendly interface makes it incredibly easy to deploy and test features in our lower environments, while also offering robust support for production releases. One of its standout features is the ability to execute gradual rollouts, allowing us to introduce new functionalities in a controlled and reliable manner.

Overall, Unleash has streamlined our deployment strategy and significantly reduced the risks associated with feature launches. I highly recommend it to any team looking for a flexible and efficient release management solution. Review collected by and hosted on G2.com.

What do you dislike about Unleash?

Nothing, I really like how it is right now Review collected by and hosted on G2.com.

What problems is Unleash solving and how is that benefiting you?

Unleash solves the challenge of managing feature flags by providing a centralized, user-friendly platform that lets you easily organize and control a large number of flags across different projects. Previously, handling multiple feature flags was cumbersome and often led to mismanagement or inconsistent configurations, especially when flags were scattered or managed manually.

What do you like best about Unleash?

First and foremost the team is very responsive and push fixes and address vulns super fast.

The categorization of the flags per projects is just awesome. The differentes Strategies available per environment are simple and perfect to keep continuously deploying app upgrades while keeping the app stable.

We are using Stretegy constraints a lot and permit to even rollout features on a per customer basis or even date.

The proxy, easy to deploy is also a very smart approach to keep things tidy and safe. Review collected by and hosted on G2.com.

What do you dislike about Unleash?

If I had to nit pick... let's say that some aspect of the UI could be improved. Review collected by and hosted on G2.com.

What do you like best about Unleash?

I enjoyed reading their documentation to understand how it works, which I found useful while researching the best way to use unleash within our infrastructure at work.

The UI is simple and intuitive, it was really easy to get started and create our first feature flags!

Their sales team does a good balanced job in engaging with you without exaggerating. Review collected by and hosted on G2.com.

What do you dislike about Unleash?

The Enterprise plan used to be a bit expensive, but with the new payg offer is now very reasonable.

Nothing major really, maybe it would be nice if unleash service could also host the proxy for you. Review collected by and hosted on G2.com.

What problems is Unleash solving and how is that benefiting you?

We use git trunk as our development strategy and it has been hard to push the team to not be worried about merging often. Feature flags will greatly help with that.

The product team will also be able to test features before we release them to a wider audience, this is great when some features are not exactly identical on staging environments. Review collected by and hosted on G2.com.
