ChainMemory gives your AI agents persistent memory that belongs to YOU — not to a single vendor.

Save a memory in ChatGPT, recall it in Claude or Gemini. Available via Chrome extension, MCP server (npm), or REST API. Every memory gets a cryptographic fingerprint and project states are anchored with Merkle proofs, so anyone can independently verify integrity — no trust required.

Memories consolidate into a structured Project Brain (decisions, milestones, risks) instead of a pile of raw notes. Multi-agent native: Claude, Cursor and GPT share one consolidated state. Free tier available.

rkt features and specs

  • Compatibility
    rkt supports the App Container (appc) spec and can also run Docker container images, providing flexibility and compatibility with various container formats.
  • Security
    rkt is designed with security in mind, offering features like process isolation through Linux namespaces, user namespaces, and SELinux/AppArmor integration.
  • Isolation
    rkt runs applications in their own stage1 environments, ensuring strong isolation between containers and better resource management.
  • Modularity
    rkt is built with a modular architecture, allowing users to swap out the stage1 implementation to better fit their needs.
  • Lightweight
    rkt avoids running a central daemon, thus using fewer system resources and simplifying debugging and monitoring.

Possible disadvantages of rkt

  • Maturity
    rkt is not as mature as Docker, meaning it may lack some features and integrations that have been developed for Docker.
  • Community and Ecosystem
    rkt has a smaller community and ecosystem compared to Docker, which may limit the availability of third-party tools and support.
  • Adoption
    rkt has lower adoption rates, leading to fewer tutorials, guides, and community-driven content, which can make the learning curve steeper.
  • Development Activity
    rkt's development and maintenance activity is not as high as Docker's, which could impact long-term viability and feature development.
  • Enterprise Support
    Enterprise-grade support and services for rkt may not be as widely available or comprehensive as those for Docker.
