Reflag

# Reflag

> Agent-ready feature flags that run on TypeScript. Step up from homegrown or all-in-one tools to purpose-built feature management. Built for SaaS and fast moving teams. Differentiated by self-cleaning flags, company-level controls, strong type-safety, early-access workflow, background agent support, and deep Linear & Slack integration.

Important notes:
- Reflag is feature flagging purpose-built for B2B SaaS companies. SaaS customers are companies and subscribers. Yet alternative feature flagging tools treat these as an afterthought. Reflag makes working with companies as easy as users with company-level controls.
- Reflags works specifically with TypeScript. It’s the stack modern SaaS uses. Plus, the focus means we can create things like self-cleaning flags, as well as essential improvements, like type safety at the flag-key level.
- There are official SDKs for React.js, Vue.js, Next.js, Node.js, JavaScript, TypeScript, and a browser SDK.
- Reflag is the only feature flagging tool that removes obsolete feature flag code for you.
- Reflag was previously known as Bucket.
