Feature flags save lives (okay, at least your weekends). They let you release features safely, test ideas with real users, and roll back when things break.

LaunchDarkly is the biggest name in the game, but it's not always the best fit. Maybe you need simple pricing, zero data collection, or an open-source option you can self-host. The good news: there are amazing LaunchDarkly alternatives out there.

In this guide, we compare some of the best LaunchDarkly alternatives in 2026, including ConfigCat, Flagsmith, Harness, Unleash, PostHog, Statsig, GrowthBook, and DevCycle.

Bun is making waves in the JavaScript ecosystem. This speedy new toolkit promises faster startup times, native TypeScript support, and improved performance compared to Node.js. But as Bun gains adoption, developers require modern tooling to match its capabilities. Feature flags are one such tool, and are perfect for Bun applications.

Coming up, we'll learn what Bun is and how it compares to Node.js, then dive into using ConfigCat feature flags in Bun projects. Finally, we'll discuss how to safely roll out new features, A/B test them, and quickly fix problems in production, all with the help of feature flags.

Manually recreating dozens of feature flags across platforms is tedious and error-prone. This guide shows you how to automate the entire migration from Prefab to ConfigCat in minutes using CLI export and natural language commands via an AI agent.

Rather than rebuilding every flag by hand, you'll export your entire Prefab configuration into a data file and use ConfigCat's AI-powered Model Context Protocol (MCP) server to transfer your configuration with minimal effort.

Prefab was acquired by Reforge and is being rebranded as Reforge Launch. If you're evaluating Prefab alternatives, ConfigCat offers a comparable feature set. With this simple migration process, you can see exactly how your Prefab feature flags behave in ConfigCat.

In this step-by-step guide, you’ll learn how to automate your Statsig feature flags migration with AI-powered Model Context Protocol (MCP) servers. Instead of writing custom scripts or manually recreating each flag, you can use natural language commands to transfer your entire configuration reducing migration time by up to 80%.

In this guide, you’ll learn how to connect your AI client to ConfigCat so you can list, create, and target feature flags using natural language with ConfigCat’s MCP server.

Feature flags help teams release features safely and quickly, but if left unmanaged, they can become stale and accumulate technical debt. To keep your codebase clean, you can use the Zombie Flags page, the Zombie Flags Report, and the Zombie Flags API. Let’s take a closer look at each of them.

Are you considering a switch from LaunchDarkly? Whether you're looking for more flexibility, cost-efficiency, or just a smoother developer experience, ConfigCat offers a refreshingly straightforward alternative. With a built-in import tool and transparent SDKs, moving your feature flags over is quicker than you might think. In this guide, we’ll walk you through the migration process - without breaking a sweat (or your codebase).

Before the open source movement, software programs were 'closed source,' meaning only software developers employed by the company could access and modify them. Outsiders were kept out through non-disclosure agreements and licenses. This exclusivity motivated the creation of the open-source movement, aiming to preserve the freedom to modify and distribute software through publicly accessible code. Today, many commercial companies actively participate in the open-source ecosystem, maintaining software that is open to the public for access and contributions. One such company supporting this effort is ConfigCat.

As the gaming industry continues to evolve, driven by technological advancement and an ever-growing demand for more immersive, engaging experiences, players no longer settle for static and predictable game worlds—they crave dynamic environments that respond and adapt to their actions in real-time.

This shift toward adaptive gaming revolutionizes development techniques, enabling developers to craft personalized gameplay as unique as the player behind the controller. At the heart of this transformation lies a powerful tool: feature flags.

We've been working on some updates to make the ConfigCat dashboard easier and more enjoyable for managing your feature flags. Let's take a quick look at these new features.
