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. Review collected by and hosted on G2.com.

- 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.

Flexible for gated access to features and also for on the fly performance optimisation settings on early adopters in early stages of application rollouts Review collected by and hosted on G2.com.

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

Our product and engineering teams have been using Configcat for a number of years after evaluating it against some competitors. We have not regretted the decision and have expanded our use over the years. Setting up an org account and managing multiple products, running experiments, gradually rolling out new features and feature variants, all has been made easier thanks to Configcat.

It's worked reliably and offers all the features our team was looking for. Review collected by and hosted on G2.com.

At the beginning there were some team and org account management features missing, which made it a bit difficult to add and remove users and assign permissions. However these were added over time and the issue was resolved. Review collected by and hosted on G2.com.

When I tested your app and sdk I found it working perfectly well. The documentation was well defined and everything went smoothly.

I used the SDK for both Flutter and Nodejs and the interaction in both cases was very simple. Review collected by and hosted on G2.com.

Usage of segments does not include validations and a missing comma can break the entire segment list Review collected by and hosted on G2.com.

ConfigCat is simple and easy to integrate while still being quite powerful.

The SDKs are feature complete and consistent across languages, which has made onboarding our team much easier.

The pricing model is fair and based on actual usage rather than somewhat artifical limits like seats, installations, clients, etc.

SSO... in every plan!

Their support is highly responsive, going so far as patching an SDK bug in an hour and even delivering on feature requests.

The Terraform provider and Public API allow control over the vast majority of the product functionality.

If you're looking for a feature flag solution, make sure to try ConfigCat! Review collected by and hosted on G2.com.

ConfigCat may not be the best fit for organizations wanting very fine-grained access control. We were able to work around some of the shortcommings but had to make some concession.

- SSO doesn't support group assignment via claims. (SCIM is on the roadmap, which is likely a better approach)

- Permissions are largely granted at the product and environment level. I would have also liked the config level.

- Product members can only be part of a single group per product, which makes provisioning via pre-existing organization security groups more challenging. We ended up generating and provisioning a group per member per product.

- Products and configs are very isolated. Segments can only be used with-in a single product. Flags conditional on other flags only work with in a single config. Review collected by and hosted on G2.com.
