Flagsmith Reviews & Product Details

Unlike other providers, Flagsmith gives us the perfect balance of power and simplicity: enterprise-grade control without unnecessary complexity. It makes safe, targeted rollouts easy, gives our product and engineering teams the same clear view and adapts seamlessly to different environments. We found Flagsmith faster to integrate, more transparent, and better aligned with how our modern team want to ship features.

Flagsmith’s customer support has been excellent: responsive, knowledgeable and genuinely invested in our success. Compared to other providers, the team feels more like a partner than a vendor, helping us get up and running quickly and connected with us on Slack for technical support.

There’s very little to dislike - Flagsmith does what it promises really well. If anything, we’d love to see even more built-in analytics and experimentation features to extend beyond feature flags. Review collected by and hosted on G2.com.

Flagsmith offers a clear UI that both technical and business user have no problem to understand.

Managing flags and integrating them in our workflow is straightforward and does not get in the way, without hiding everything behind dark magic.

Last but not least, its integration with the

OpenFeature standard give us great testing capabilities and reduce the fear of vendor locking Review collected by and hosted on G2.com.

I wish the Jira integration would also work with on-prem instances Review collected by and hosted on G2.com.

Flagsmith has been a remarkably easy to use and performant flagging solution for our enterprise. Not only does it have the segmentation capabilities that we were looking for, but it's auditing capabilities and its integration with downstream tooling has been extremely helpful. Additionally, thanks to its terraform drivers, we've been able to automate and manage through source control our configuration. Finally, the fact that it can be self-hosted means that we are able to meet our security requirements. Review collected by and hosted on G2.com.

The only real disadadvantage we've run into so far is that there isn't an integration with JAM stack providers like Vercel. I suspect that in time, this will not be an issue. Review collected by and hosted on G2.com.

Working with Flagsmith has been a fantastic experience. Their product is top-notch—high-quality, reliable, and well-designed. The support team has been incredibly responsive and helpful, making implementation smooth and hassle-free. It’s been a pleasure collaborating with them, and I highly recommend Flagsmith to anyone looking for a robust feature flagging solution! Review collected by and hosted on G2.com.

Nothing really, they had all functions we were looking for Review collected by and hosted on G2.com.

Flagsmith is pretty simple to use, it has all the basics feature but also powerful enough segmentations, integration for clients is easy and does the trick. We are a small startup and we didn't have any limitation but I also worked in big orgs with not that powerful feature flagging systems where flagsmith could have been used instead. Review collected by and hosted on G2.com.

The UI / dashboard is intuitive, perhaps I would like the environment to be merged so that you can create a flag and without switching around you decide the values for each environment.

the SDKs could be more complete, they are quite flexible as it only exposes the basics but sometime I wish we had a few-liner solution that takes care of caching and loading the flags without opening to mistakes. Review collected by and hosted on G2.com.

Flagsmith has been an incredibly useful tool for me in the past year. I have used it for more than 5 projects of mine. The projects are based on different tech stacks like Java, Python, Go, JavaScript and the integration was extremely seamless. These are large size projects with multiple features.

The best part about it is the extremely low latency and high availability of the system. The local feature flag evaluation mode proved to be a game changer, allowing me to quickly check all feature flag values without any additional delay.

Flagsmith has made feature flagging and A/B testing mechanism so simple to implement that it is the first name which comes to my mind now when I hear about Feature flagging. They already support most of the programming languages and are building so many new integrations, that everytime you visit their website there is something or the other that's new.

The Flagsmith UI is also so easy to understand and get onboarded which makes it super convinient to use by both developers and non technical folks.

I would highly recommend everyone to use Flagsmith for their projects and save a lot of time. Review collected by and hosted on G2.com.

Nothing at all, I love the way they are expanding and would love it see it growing always. Review collected by and hosted on G2.com.
