Simple, Reliable, and Developer-Friendly Feature Toggle Tool

  • May 27, 2025
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
ConfigCat helps us reduce deployment risk by decoupling code releases from feature rollouts. It allows our development and product teams to test features in production with specific users or groups, gather feedback, and make adjustments before a full release. This results in faster iteration cycles, fewer rollbacks, and a more stable user experience. Additionally, its easy-to-use dashboard and robust SDKs help our teams stay productive without unnecessary complexity.

Best combination of capability and price

  • May 23, 2025
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
ConfigCat allows our R&D team move more quickly by enabling our team in having confidence that a feature can be turned completely off at run-time.

Simple integration for powerful and controlled feature rollout

  • April 10, 2025
  • Review provided by G2

What do you like best about the product?
Flexible for gated access to features and also for on the fly performance optimisation settings on early adopters in early stages of application rollouts
What do you dislike about the product?
History not massively useful - would be great to have longer retention
What problems is the product solving and how is that benefiting you?
Single place for all feature config related aspects including enablement/disablement

Fairly priced product for bigger teams with excellent support and industry leading feature set

  • December 30, 2024
  • Review provided by G2

What do you like best about the product?
- 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.
What do you dislike about the product?
- 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
What problems is the product solving and how is that benefiting you?
Allowing us to separate deployments from releases. Also allows us to gradually release a feature to users. Enables to do more controlled feature releases.

ConfigCat is a Game-Changer for Our Release Flow

  • December 06, 2024
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
We can easily perform A/B tests and canary releases using ConfigCat, which helps us boost both the productivity of the development team and test new features only with a subset of users.

Critical to our business

  • November 27, 2024
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
Feature flags are critical to our ability to rapidly deliver features to our clients. Being able to test features early makes it far more likely that we deliver things our clients need and that work as intended.

Excellent product

  • November 19, 2024
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
Usage of segments does not include validations and a missing comma can break the entire segment list
What problems is the product solving and how is that benefiting you?
Feature flags and A/B testing

Reliable feature flag solution for our engineering and PM teams

  • July 15, 2024
  • Review provided by G2

What do you like best about the product?
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.
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
We're regularly releasing feature iterations or new features in our product and need a solution that lets us control what gets released to which user cohort, measuring results and reacting quickly if a release introduces issues in the product. Configcat's feature flagging solution solves this problem for us.

Great product, fair pricing model, and fantastic support!

  • May 14, 2024
  • Review provided by G2

What do you like best about the product?
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!
What do you dislike about the product?
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.
What problems is the product solving and how is that benefiting you?
* Simplify coordination of release timing
* Incremental releases, targeted releases
* Kill-switch
* Maintenance mode, forced updates, graceful degredation

Easy to setup and get going!

  • August 10, 2023
  • Review provided by G2

What do you like best about the product?
Its easy to use and implement, which does not mean its lacking in features!

There a lot of targetting rules, segments, environment and configs all make sense, clients and sample implementations for a lot of coding languages.

We've used split in the past and configcat to us has been easier to understand and onboard other folks while maintaining the set of features we liked from split
What do you dislike about the product?
The one thing I would recommend improving is how segments are use, segments allow you to group how to target your users but you can change them and affect all environments, I found that to be a bit scary if you dont know what you are doing
What problems is the product solving and how is that benefiting you?
We are releasing quite frequently our product and configcat is allowing us to not slow down, continue to build and ship and engage with our customers as beta testers and allow them an early view of what we are building-
