Feature Flag Service

feature flag service icon
A leading feature flag service that provides a friendly dashboard to manage features and several SDKs supporting all significant technologies. Just flip the visual feature toggles on the feature management dashboard to change the feature flag values, and let the SDKs distribute those changes to your applications.

Feature Management

feature management icon
Product managers can do canary releases, target individual users, or have random-based percentage rollouts. Dark launch new features and mitigate release relates risks by testing in production.

Public Management API

public management api icon
Development teams can create and update feature flags from any script or program using the API. It provides all the functionality of the dashboard but is built for programs.

Configuration Management

configuration management api icon
Supporting DevOps engineers to manage application configurations remotely via a comfortable UI. Able to store string, number, and text-type variables on top of boolean feature switches. Mandatory notes and audit log helps the remote configuration management to stay compliant.

LaunchDarkly Alternative

launchdarkly alternative icon
LaunchDarkly is a great service, but we have heard those asking for an alternative release management solution. ConfigCat offers a transparent, flat pricing structure, a simple UI, a forever free plan, plus all the security features even in the Free subscription. How does it compare to LaunchDarkly? We aim at 90% of the power with only 10% of the complexity.

Feature Flag Best Practices

feature flag best practices icon
Software developers apply feature flag best practices like using their own consistent naming convention, leaving notes, keeping the feature flags' scope clear, connecting your feature flag service with your project management system (JIRA, Trello), and removing zombie (stale) feature flags.

Canary Release or Phased Rollout

canary release icon
Product managers can deploy experiments to a smaller number of users first. And make them available for a wider audience only when confident. It’s good to roll out new features gradually and feature changes to production, test on low-risk user groups first and move slowly.

Security

security icon
Enterprise-level security features are available in all plans for site reliability engineers, including SSO, SAML, 2FA, because security shouldn’t be a question of money.

A/B Testing

A/B testing icon
To do A/B tests, you have to solve two problems. First, you have to split your users into random segments. Then you have to measure the successful conversions. Percentage rules let you create random segments, and the ConfigCat SDKs help you send feature flag data into analytics tools to visualize the test results.

User Targeting and Segments

targeting and segmentation icon
Target a particular group of your users with segments. User segments can be assigned to multiple feature flags, making them ideal for beta testing.

Free Feature Flag Service

feature flag service icon
The Free plan lets you use all features, including essential security features like SSO, multi-factor authentication, and SAML. You can use the forever-free plan to manage your features or evaluate the feature flag service in case the purchase decision takes longer.

Trunk-based Development

trunk-based development icon
At the code level, using feature flags is an alternative to using feature branches. Using fewer feature branches means less merge hell and a happier developer team.

Tech Debt

tech debt icon
While feature flags are a great way to decouple releases from deployments, having unused flags in the source code adds to the technical debt. Engineers can use the code scanner CLI tool to eliminate tech debt and help them keep the code clean. The zombie flags report warns about flags that are likely not in use anymore.

GDPR compliant

GDPR icon
We are in the European Union under the GDPR regulation. Your site reliability engineers can set up the service to store your data only within the EU. The EU-only option is included in all plans, even in the forever-free plan. You can always switch to the Global option that provides improved performance for your users outside of the EU as an alternative. Starting with the Dedicated plans, you can opt for other regions, including the US, Canada, UK, or Australia.

Open-Source SDKs

open-source icon
They are supporting every major technology with step-by-step guides for easy integration. All SDKs are on GitHub, and we are happy to receive improvement requests. The SDKs are MIT licensed to use in your application without any restrictions.

Easy to learn UI

easy to learn icon
Enables customer care and support professionals to be productive in managing feature flags on an easy-to-use browser interface. The feature management dashboard is designed to take less than 10 minutes to learn, even for non-technical people to learn basic feature flagging. Just log in, flip the feature toggles, and see the application features turned ON or OFF.

Emergency Kill Switch

emergency kill switch icon
Release with confidence and rollback changes if anything goes wrong. The emergency kill switch takes out the stress from the most critical point of the software delivery lifecycle, resulting in a more confident product manager, a content release manager, and a happy software engineering team.

Premium Support

premium support icon
