LaunchDarkly Alternatives: 8 Tools to Consider in 2024

What Is LaunchDarkly? 

LaunchDarkly is a feature management platform that enables developers to manage new features and updates to their applications. It allows teams to manage feature flags, which are conditional statements in code that control availability for software features. 

By using LaunchDarkly, developers can decouple feature rollout from code deployments, enabling more granular control and reducing the risk of introducing bugs into production systems. This platform supports multiple environments, such as development, testing, and production, making it easier to ensure feature consistency.

LaunchDarkly also provides detailed analytics on how features are being used, helping teams make data-driven decisions. It supports A/B testing, allowing developers to experiment with different feature versions and measure their impact on user behavior. Additionally, LaunchDarkly integrates with popular development tools and CI/CD pipelines.

Limitations of LaunchDarkly 

LaunchDarkly has several limitations that are leading some organizations to seek alternatives. These limitations were reported by users on the G2 platform:

• Not fully turn-key: The platform only allows the delivery of hard-coded string values based on a true-false flag set in the interface. This simplicity falls short of the initial concept of a turn-key options management system.
• Integration complexity: Integrating LaunchDarkly into a codebase can be less smooth than expected, with users reporting frequent outages that disrupt workflow. 
• User experience issues: The user interface has been described as confusing. Some users struggle to perform basic tasks such as cloning a flag. There is also a lack of attention to certain SDKs, such as the Flutter SDK, which can be problematic for developers using that platform.
• Cost: LaunchDarkly can be expensive for basic use cases, which may deter medium-sized organizations from adopting the tool. 
• Limited applications: As a software as a service (SaaS) solution, it is not suitable for on-premises deployments, limiting its applicability in certain scenarios. Additionally, storing essential secret key information on the client side can pose security risks.
• Steep learning curve: The setup process for LaunchDarkly is time-consuming, and the learning curve can be steep for new users. Day-to-day operations require multiple clicks and screens, while more complex tasks can be executed with a single click, highlighting inconsistency in the UI design. 

Notable LaunchDarkly Alternatives and Competitors 

1. Configu

Configu is an end-to-end ConfigOps infrastructure that empowers engineering teams to seamlessly manage and collaborate on software configuration data—such as environment variables, secrets, and feature flags—across any system or environment.

Features:

• A Powerful Config Validation System: Before write or read, Configu validates that the configuration input complies with the defined schema (the cfgu file), including type, pattern (regex), required, and depend.
• Prevents Missing Configurations: If a config is defined as “required” Configu won’t let the service compile, build or run. If a configuration is missing during a CI/CD build, Configu will prevent it from deploying.
• Configuration Test Framework: As a single source of truth, Configu lets you enforce security, eliminating the need to keep passwords in text files.
• Prevents Config Duplications: Configu prevents config duplications in two ways:
  • Values propagate consistently to sub-sets
  • Keys are defined once and applied everywhere
• Orchestrate Configs Across All Systems: Configu works with everything you use to manage configurations: secrets and feature flag managers, databases, PaaS & clouds, IaC, CI/CD and more.
• Configuration-as-Code: With Configu’s CaC format (.cfgu), the configuration declaration is written and stored alongside the application’s source code 
in a Git-like version control system.
• Version History and Recovery: Configurations can be versioned alongside the code, allowing developers to always match between them, roll back to previous versions, and have 
a historical record of all modifications.
• Auto-Completion & Linting: When working on a CFGU file in VSCode,  the Configu plugin auto-completes with configs you have anywhere in your code and can use. 
It enables linting, preventing broken cfgus, and validating the schema structure.
