grafbase vs locus
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.; locus: Locus provides persistent project-aware memory for AI coding tools, using three memory layers: structural, semantic, and episodic. It works with any MCP-compatible client and offers 14 tools and 3 resources for exploring, searching, and managing memory. Carbon Copy enables passive conversation capture for later recall.
