LaunchDarkly vs GitLab

GitLab compared to other DevOps tools



Launchdarkly is a feature delivery and feature management service offering. This means that the service they provide allows their customers to dynamically control when new features (within their application) become available to their end users. Launchdarkly’s service offering represents a tool within the DevOps Toolchain that aligns within the Continuous Delivery (CD) tool category.


Launchdarkly provides a very sophisticated feature management service that enables Development and Operations teams to deliver code faster with minimal risk by using feature flags to deploy code when they want while keeping new features hidden until product and marketing teams are ready to share. Their service allows customers to take full control of feature releases through:

-Fast feature delivery: separating code deployments from feature deliveries

-Incremental changes: controlling feature rollouts into predefined stages and slowly test the functionality within production before confirming it’s safe to proceed to the next step

-Canary launches: rolling features out to a small number of users to assess the reaction of the overall system (also known as Percentage Releases)

-Dynamic feature control: coordinating and delegating release control to other teams in your organization, turning off features when they are causing performance issues or poor user experiences (feature kill switch), and retiring features.

-Automated feature delivery: setup scripts that automatically turn features off/on or adjust a flag’s targeting rules based on metrics from Application Performance Management (APM) tools

-Analytics: providing deep insights across all features and how they are performing with Flag Insights; understanding how the application and team members are using LaunchDarkly.


Launchdarkly is a niche solution that must be overlaid within a customer's existing DevOps Toolchain. Though they do provide more comprehensive feature flag configuration capabilities, they lack:

-A Holistic DevOps Solution: unable to meet customers complete DevOps needs with a single application Toolchain

-Reasonable/Economical pricing: high per-user price point for a single tool (Launchdarkly’s pricing starts at $90/user for their lower tier plan, $390/user for their mid-tier plan and they don't offer a free base tier)

-Industry recognition: no industry recognition by research and advisory bodies such as Gartner and Forrester.

-Meeting/Phone Support: no option to request escalating a technical support inquiry to a troubleshooting call/meeting

Gitlab’s DevOps Toolchain includes feature flags for feature management as Launchdarkly does. Unlike Launchdarkly, Gitlab’s Toolchain offers deeper features/functionalities necessary for quickly delivering high quality applications and services for the entire software lifecycle in a single application. Examples of GitLab features/functionalities that are not offered by Launchdarkly include Source Code Management (SCM), Continuous Integration (CI) and Security Embedded within the DevOps workflow (DevSecOps).

この機能を使うと、ソフトウェアのフィーチャーフラグを製品内で直接設定・監査・管理することができます。 新しいフィーチャーフラグを作成し、ソフトウェア内の簡単な API の指示で検証するだけで、 GitLab 内のフィーチャーフラグを使ってソフトウェアの動作を制御することができます。 フィーチャーフラグの戦略は環境ごとに設定することができます。 GitLab のフィーチャーフラグには、フィーチャーフラグを操作するためのAPI が含まれています。


Percent of Users Strategy for Feature Flags

You can select "Percent of Users" as a rollout strategy for your feature flags. This allows percentages to be set individually for each environment and each flag. When "Percent of Users" is configured and the flag is enabled, the feature will be shown to the configured percentage of logged-in users. This allows you to do controlled rollouts, monitoring the behavior of the target environment to ensure the results are as expected.



フィーチャーフラグのロールアウト戦略として「ユーザID」を選択することができます。 ユーザーID戦略では、ユーザーIDをカンマで区切ったリストを指定し、指定したユーザーのみにフィーチャーフラグを有効にすることができます。 これにより、ユーザーベースの特定のコホートやセグメントをターゲットにして、機能をテストすることができます。





User List Strategy for Feature Flags

You can choose "User List" as a rollout strategy for your feature flags. User lists can be reused for multiple feature flags while allowing you to manage them in a single location. You can create Feature Flag user lists from the API, and edit or delete them from the API or UI.


Associate Feature Flags with the issue(s) that is related to them

You can create a link from the issue that introduced the feature flag to the feature flag itself. That relationship is visible in the feature flag details.
