Bucket (rebranded to Reflag in 2026, reflag.com) is a TypeScript-first feature management platform built for B2B SaaS teams. It provides feature flags with self-cleaning lifecycle automation, AI/agent integration via a hosted MCP server, strongly typed SDKs for React, React Native, Vue, Next.js, Node.js and the browser, OpenFeature providers, local flag evaluation for zero-latency and downtime protection, feature entitlements, in-app feedback collection, and deep integrations with Linear, Slack, GitHub, Datadog, Vercel and analytics tools. The platform exposes two APIs — a Runtime API for evaluating flags for users and companies at request time, and a Management API for programmatically managing apps, environments, flags and targeting rules from CI/CD. Backed by 500 Global and Creandum.
