ctx-open vs grafbase
ctx-open: CTX is a cognitive version control system for AI agents, preserving structured reasoning artifacts as durable state instead of ephemeral chat transcripts. It enables agents to maintain continuity across sessions, track decisions, and reproduce reasoning paths. The system includes a CLI, a local MCP server, and a web viewer.; 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.
01
TL;DR
Choose ctx-open if…Multi-session agent continuity: resume work across interruptions without re-investigation
Choose grafbase if…Unifying disparate microservices, legacy systems, and third-party APIs into a single federated GraphQL API.
