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.

PM2 features and specs

  • Process Management
    PM2 provides efficient process management, allowing you to easily start, stop, and restart applications. It handles the daemonization of processes and ensures that all your services run continuously.
  • Monitoring & Logging
    PM2 offers robust monitoring and logging features, providing real-time metrics on CPU and memory usage, along with comprehensive logging to help debug issues and monitor application performance.
  • Cluster Mode
    PM2 supports cluster mode, enabling you to run multiple instances of your application to utilize multi-core systems effectively, thereby improving performance and handling more traffic.
  • Easy Deployment
    With PM2, deployment is simplified through built-in functionalities like management of environment variables and automatic startup scripts, making it easier to deploy applications across environments.
  • Platform Agnostic
    PM2 is platform-agnostic and can be used with diverse environments and languages, though it is optimized for Node.js applications, offering flexibility to manage various types of applications.

Possible disadvantages of PM2

  • Overhead
    While PM2 is lightweight, it can add some overhead, particularly in smaller or simpler applications where its full range of features may not be necessary.
  • Configuration Complexity
    For new users or simple applications, PM2's configuration options may seem complex, with a steep learning curve to understand and leverage all available features effectively.
  • Memory Usage
    PM2's memory usage can be higher compared to more minimal solutions, which might be a concern for resource-constrained environments or small-scale projects.
  • Limited to JavaScript by Default
    Although you can manage other types of applications, PM2 is primarily designed for Node.js, so managing non-JavaScript applications could require additional effort or wrappers.
  • Potential Issues with Large Projects
    In some cases, PM2 may face challenges scaling very large projects due to its process management design, requiring more thorough testing and configuration tuning.

    There's also a CommonJS version, index.js for those who prefer it. With either version, app instantiation is followed by the GET handler returning "Hello World!". The rest sets up the server on the designated PORT and exports the app. Unlike Flask, the Express server is much more performant and can be used in production, perhaps with the help of tools like cluster and PM2. - Source: dev.to / over 1 year ago
