What I like most about ConfigCat is its simplicity and ease of use. The dashboard is clean and intuitive, and integrating it into our applications was fast and straightforward. It supports progressive feature rollouts and user targeting, which helps us test features safely in production. I also appreciate that the SDKs are open-source and well-documented, which builds confidence in the platform. Review collected by and hosted on G2.com.

While ConfigCat works really well, it lacks some advanced analytics and experimentation features, such as deeper A/B testing capabilities and native impact reports. Pricing can also become a concern as the number of environments and users grows, especially for larger teams or organizations with more complex needs. Review collected by and hosted on G2.com.

For real continuous delivery, the development of features needs to be isolated, so that the code is ready to go to production at any time. ConfigCat does that for us flawlessly without any integration issues. Its usage has been self-explanatory and without further need of documentation or customer support. The overview of feature toggles across all environments is very helpful to see the general status of development in a project. Review collected by and hosted on G2.com.

The only thing that is not really easy to do with the way we use ConfigCat is the isolation of features that span multiple teams and/or services. We would need to define an overarching product for that. Review collected by and hosted on G2.com.

- very easy and straightforward to implement with the many options they provide with their different SDKs for different languages.

- very responsive support

- extensive options to implement more advanced feature flags and rollout strategies

- Very competitive pricing in comparison to some of their competitors Review collected by and hosted on G2.com.

Their Dashboard sometimes has a little confusing UI, which could use some improvements. Review collected by and hosted on G2.com.

ConfigCat is a no-frills solution in a crowded space and is easy to get started with. Our team was able to get ConfigCat integrated into our first product in a matter of a couple of days with no real road blocks. The way that ConfigCat uses deterministic methods to ensure that users are segmented properly, whether it's through the UI SDK or server-side SDK is great, as data remains on your client. This makes feature flag segments extremely fast within the product. Review collected by and hosted on G2.com.

ConfigCat is not nearly as full-featured as some competitors in the feature flag space; I could see how trying to use ConfigCat to perform A/B testing may be difficult, as the analytics/usage are not extremely robust. Review collected by and hosted on G2.com.

Is so easy for new users start to create and integrate in our application Review collected by and hosted on G2.com.

there is nothing that i can mentionate, because we use it and we are loving it. Review collected by and hosted on G2.com.

The tool is great for the price to add to your platform out-of-the-box features for features progressive and segmented activation, pretty useful for running betas, a/b tests, etc.

Their support team is also great, highlighting where we are over the quota for instance and being flexible in us fixing certain things before asking to move to the next plan. Review collected by and hosted on G2.com.

Nothing that I'm aware of. Maybe the tool is not as sophisticated as others to support experimentation E2E. Review collected by and hosted on G2.com.

- We liked that instead of having a seat based pricing model, ConfigCat just has different packages, but all can have unlimited users. This makes pricing predictable and the product guilt-free to use with larger teams, where some members might need to use the platform very often, while others only few times a quarter or etc.

- Also having the free tier available to test everything out before commiting was crucial. During that testing period it was also very clear that their support is top-notch, always responding quickly and being there to guide us. The support materials they provide are also super helpful and the wide range of differnt SDK-s makes implementation easy.

- Commitment to initiative like OpenFeature shows that they are serious and ready to be industry leader in Feature Flagging.

- In terms of their product, we like the privacy and security focus and having ability to run proxies in our own infrastructure - this was a crucial element what we needed from a feature flagging platform and it has enabled us to use feature flagging platform without compromising our SLA-s.

- The UI and UX in general could be improved. The platform is mostly used by developers, so it has not been a big issue, but people outside engineering struggle.

- We rely on many custom targeting attributes and its currently not easy to manage those, as these need to typed in manually several times, leading to typos and other silly mistakes

- Flag change review process in currently missing

- Missing integrations with product analytics tools like Heap and Planhat Review collected by and hosted on G2.com.

ConfigCat is easy to use and has been rock solid for us. It has great support for multiple products, environments, and configs within them, providing centralized feature management across multiple products.

Feature flag services often price based on MAU which is impossibly expensive for a SaaS product like ours. ConfigCat has a fair pricing model based on config downloads and network traffic that makes it feasible for us to use the product. Additionally the add-ons make it easy to tailor the costs a bit before switching to a higher plan and they've been more than willing to work with us. Review collected by and hosted on G2.com.

The UI can be a bit complex for a first timer, but is workable once you understand the concepts. We have engineers, product managers, and support working in there. Review collected by and hosted on G2.com.

ConfigCat has been a game-changer for our release flow. We love how it enables us to seamlessly implement A/B testing and canary releases, which are critical for our deployment strategy. The tool is straightforward to integrate and use, allowing us to experiment and release features confidently without disrupting our users. Their support team is also a standout – always responsive and helpful whenever we need assistance, ensuring we can tackle any challenges promptly. Review collected by and hosted on G2.com.

One small limitation we encountered with the free plan is the cap of 100 specific email addresses that can be assigned to a feature flag. For our needs, this was a bit restrictive as we required a higher limit. That said, this is a minor issue compared to the overall value and quality of the service, which has been excellent.

History not massively useful - would be great to have longer retention Review collected by and hosted on G2.com.
