grafbase vs jamjet
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.; jamjet: JamJet is an action-control plane for AI agents that enforces safety policy across hooks, guardrails, MCP gateways, SDKs, and custom runtimes. It blocks unsafe tool calls, requires human approval for risky actions, caps costs, and provides a durable audit trail. One policy file works everywhere, supporting frameworks like Claude Code, OpenAI Agents SDK, LangChain, and more.
