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.

KeystoneJS features and specs

  • Ease of Use
    KeystoneJS offers a straightforward and developer-friendly environment with its intuitive Admin UI, making it easy to work with for beginners and experienced developers alike.
  • Flexible Schema
    Its flexible data modeling allows developers to define custom schemas and relationships, which can be tailored to meet the specific needs of a project.
  • Built on Node.js
    Being built on Node.js, KeystoneJS benefits from Node's vast ecosystem, allowing for easy integration with other Node packages and tools.

    As an open-source project, KeystoneJS has an active community that contributes to its development, ensuring regular updates and community support.
  • GraphQL API
    KeystoneJS automatically generates a GraphQL API based on your schema, providing modern API capabilities and powerful querying options.

Possible disadvantages of KeystoneJS

  • Development Community
    While active, the development community is smaller compared to other popular frameworks, which might limit the availability of third-party plugins and resources.
  • Documentation
    Some users have reported gaps in the documentation, which can pose challenges when trying to implement advanced features or debug issues.
  • Performance Overhead
    Like many CMS solutions, there can be significant overhead, and performance might not match solutions built from scratch for high-performance demands.
  • Learning Curve
    Though easy to start with, mastering its full potential requires a deep understanding of GraphQL and Node.js, which might be a hurdle for some developers.
  • Limited Built-in Features
    KeystoneJS provides a basic set of features out of the box, meaning additional functionality may often need to be custom-developed, increasing development time.

Keystone was created by this Australian company called Thinkmill. They have used it to help businesses build custom backend systems for more than a decade. But it needed to be deployed separately from Next and they were using emotion css... - Source: Hacker News / 2 months ago
  • Is Prisma ORM ready for production?
    Also, there are lots of exciting web frameworks that use Prisma as their default ORM layer (like RedwoodJS which is built by the founder of GitHub, Amplication which recently raised $6.6M in seed funding, Wasp (YC W21) or KeystoneJS) which should give you some more validation that Prisma is being used in a lot production applications :).
