Feature Flags and DevOps

Empowering Continuous Delivery and Experimentation

Feature Flags and DevOps

In the fast-paced world of software development, the ability to deliver new features and updates swiftly and safely is paramount. DevOps practices have revolutionized the industry by emphasizing collaboration between development and operations teams to automate and streamline the deployment pipeline. One key tool in achieving this goal is the use of feature flags, and Flagsmith is at the forefront of making this process seamless and efficient.

Understanding Feature Flags

Feature flags, also known as feature toggles or feature switches, are a powerful technique that allows developers to enable or disable specific features within an application or service without modifying the codebase. They act as conditional branches, letting you control which features are visible or active for different users, environments, or segments of your audience.

Once upon a time in a bustling tech startup, Sarah, a talented DevOps engineer, found herself facing a dilemma. The development team was eager to release a major update to their flagship application, but they were concerned about potential bugs and performance issues that might arise after deployment. Sarah knew that a failed release could spell disaster for the company's reputation and bottom line. That's when she decided to implement feature flags into their deployment process.

With feature flags, Sarah could control the activation and deactivation of specific features within the application remotely. This meant that instead of releasing the entire update at once, she could gradually roll out features to a subset of users for testing and monitoring. If any issues arose, she could easily disable the problematic feature without affecting the rest of the application. This approach allowed Sarah to minimize the risk of a catastrophic release and gave her team the flexibility to iterate on features based on real user feedback. It also empowered the product team to gather valuable insights and make data-driven decisions and meant that they didn't have to rely on engineers to roll out to select users, ultimately leading to a smoother and more successful deployment process. Thanks to feature flags, Sarah became a hero in the company, ensuring that DevOps played a pivotal role in the organization's continuous delivery and improvement efforts.

Feature Flags and DevOps: A Synergistic Relationship

1. Continuous Integration and Continuous Delivery (CI/CD)

In the DevOps world, CI/CD pipelines are the backbone of software development and deployment. Feature flags seamlessly integrate with CI/CD practices by enabling you to safely release code to production while keeping features hidden from users. This allows for continuous integration, testing, and delivery without the need for complex branching strategies.

By using feature flags, you can release features incrementally and monitor their performance in real-time. If an issue arises, you can quickly disable the feature, preventing downtime or degradation in user experience.

2. Infrastructure as Code (IaC)

IaC is another fundamental DevOps practice that treats infrastructure provisioning as code. Flagsmith aligns with IaC by enabling you to manage feature flags as part of your infrastructure codebase. This means you can define and deploy feature flags alongside your infrastructure, making it easier to version control and replicate your setup across different environments.

With Flagsmith, you can apply feature flags to specific infrastructure components, allowing for dynamic control over resource allocation, scaling, and failover strategies.

3. Automation

Automation is at the heart of DevOps, and feature flags contribute by automating feature release and rollback processes. With Flagsmith's automation capabilities, you can schedule feature releases, set expiration dates, and automatically roll back features if they cause issues, all without manual intervention.

Flagsmith: Empowering DevOps with Feature Flags

Flagsmith is a standout player in the world of feature flag management, offering a comprehensive and developer-friendly solution. Here are some key aspects that set Flagsmith apart:

1. Integrations

Flagsmith excels in integration capabilities, seamlessly connecting with various tools in the DevOps ecosystem. You can integrate feature flags with observability tools to monitor the impact of feature changes on user experience or use feature flag data to fuel A/B tests in your analytics tool. This level of integration empowers data-driven decision-making and ensures a holistic view of your software's performance.

2. Bootstrapped Open Source

Flagsmith's commitment to being a bootstrapped open-source company is significant. It reflects their dedication to providing a genuinely useful developer tool while remaining transparent and avoiding pricing and lock-in concerns often associated with venture capital-funded companies. This approach aligns perfectly with DevOps principles of transparency, collaboration, and community-driven solutions.

3. Use Cases

Flagsmith offers a wide range of use cases, from simple feature toggling to advanced A/B testing and multivariate experimentation. DevOps teams can use feature flags to:

  • Phased Rollouts: Gradually release features to different user segments or environments.

  • Remote Configuration: Modify feature behavior without deploying new code.

  • A/B and Multivariate Testing: Conduct controlled experiments to optimize user experience.

  • Organization Management: Keep deployments organized with role-based access and project management features.

4. On-prem deployments

Flagsmith provides the flexibility of on-premises deployments, catering to the needs of teams seeking to exert complete control over their infrastructure. With the option to host Flagsmith on-premises, organizations can ensure that their feature flags are co-located within their own environment, thereby enhancing application-level security to the fullest extent. This approach not only bolsters security but also minimizes service-to-service latency, ensuring optimal performance and responsiveness within the system. Whether it's for stringent security requirements or the desire for greater control, Flagsmith's on-premises deployment option empowers teams to tailor their feature flag management according to their specific needs.


Feature flags are a pivotal element of DevOps practices, enabling teams to release software incrementally, manage infrastructure as code, and automate deployments effectively. Flagsmith, with its integrations, bootstrapped open-source approach, and versatile use cases, empowers DevOps teams to implement feature flags seamlessly and accelerate their software delivery lifecycle.
