Flagsmith Reviews

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.

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.

It has improved deployment safety by allowing quick rollbacks and environment-specific configurations. For us, this streamlines e-commerce feature releases, improve experimentation capabilities, and, thanks to its self-hosted option, ensures security compliance.

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!

Nothing really, they had all functions we were looking for

Minimize branching

I like how Flagsmith changes the game of testing things out, just like toggling a switch instead of going the complete DevOps route. With that, a developer can easily test features in production.

Nothing. The product is well-built and open for feedback

I think a major benefit of Flagsmith is reducing the old tedious and time-consuming process of testing in production, which was highly dependent on roles like a DevOps engineer.

What I love about Flagsmith:

✅ Supports a wide variety of programming languages

✅ Offers powerful segmentation for targeted rollouts

✅ Provides analytics to track feature performance

.Flexibility, ease of use, work-flows, organization

Not much to complain about here, maybe that it's not completely free?

The quick start guide, UI and library functionality works exactly as you would expect. I rolled my own feature flag systems in the past and now that Flagsmith exists as a mature product, there would never be a good reason to again!

Nothing so far - my current usage is fairly routine.

Feature flag system that caches local state and integrates well with my choice of tech stack. Benefits me through a simple, discoverable UI and clear documentation.

It is Open Source! Quick and easy to integrate, then all the powerful features come alive. Plus great support from the team.

Nothing, I really enjoy using it. Highly recommend.

Decoupling release from deployment and allowing non coders to change text and public features.

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.

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.

We mostly use flagsmith for continuous delivery, to turn off features that are in development and do incremntal rollouts

Easy to implement and quick to production. Great customer support

It allows me as a

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.
