grafbase vs mex
grafbase: Grafbase is a self-hosted, Rust-powered GraphQL Federation Gateway for high-scale, mission-critical applications. It unifies diverse data sources and microservices into a single, performant GraphQL API, offering enterprise-grade security and flexible deployment options.; mex: mex provides persistent, navigable project memory for AI coding agents, allowing every session to start with the right context instead of a cold prompt. It structures agent memory through a markdown scaffold, offers CLI tools for drift detection against the real codebase, and synchronizes context to keep agents aligned and reduce token usage.
01
TL;DR
Choose grafbase if…Unifying disparate microservices, legacy systems, and third-party APIs into a single federated GraphQL API.
Choose mex if…Maintaining consistent project context for AI coding agents across multiple sessions.
