How It came into being

It was just another evening. I was mindlessly scrolling through my podcast list when this gem caught my eye -

The guest once mentioned something called Feature Flags and my interest piqued, I turned up the volume.

Feature Flags vs. Environment Variables

As I dug deeper, I realized that while feature flags and environment variables share some similarities, they serve fundamentally different purposes.

Environment variables are static configuration settings that typically differ between environments (development, staging, production). They're great for storing API keys, database URLs, or toggling simple boolean flags.

Feature flags, on the other hand, are dynamic configuration points in your application that can be changed on the fly, without redeploying your code. They allow for fine-grained control over feature rollouts, A/B testing, and even personalized user experiences.

What is Switchr?

Switchr is a Dynamic Feature Flag Management Tool.
It is a powerful, designed to streamline feature flag implementation in your development process. This tool allows for real-time feature flag management, project-based organization, and role-based access control (RBAC).

Key features:

  • Project-based feature flag management

  • User management and RBAC

  • Real-time feature flag updates

  • REST API access

  • High-performance flag retrieval using Redis

Building the Tool

I built the tool using a modern tech stack:

  • Frontend: NextJS for a snappy, responsive user interface

  • Backend: Golang for high-performance API and business logic

  • Database: Redis for lightning-fast feature flag retrieval and PostgreSQL for persistence.

Features of Switchr

  • Speed up development - Deploy faster by decoupling code deployment from feature release

  • Improved Collaboration - Manage your development teams effortlessly. Add or remove members, assign roles, and control permissions within each project.

  • Flexibility and Control - Toggle features on or off instantly to test, manage, or roll back releases

  • Scaling - Switchr's Redis-backed architecture ensures fast and reliable performance, no matter the scale

  • Easy Feature Flag management - Effortlessly create, update, and delete feature flags with full CRUD support, directly from the dashboard.

Conclusion

What started as a casual listen to a tech podcast turned into a journey of discovery and creation. Feature flags have transformed how we think about deploying and managing software features. They provide a level of flexibility and control that goes far beyond what traditional environment variables can offer.

If you're still relying solely on environment variables for feature toggles, I encourage you to explore the world of dynamic feature flags. Whether you build your own system or use an existing solution, the power and flexibility they offer can be a game-changer for your development process.
