ChainMemory gives your AI agents persistent memory that belongs to YOU โ€” 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 โ€” 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.

Thunder Client features and specs

  • User-Friendly Interface
    Thunder Client offers a clean and intuitive interface that makes it easy for users to create and manage API requests without getting overwhelmed by complex features.
  • VS Code Integration
    Being an extension for Visual Studio Code, it is convenient for developers who already use VS Code, enabling seamless API testing within their development environment.
  • Lightweight
    Compared to other API testing tools, Thunder Client is lightweight, making it ideal for users who need a quick and simple solution for testing APIs without extensive configuration.
  • Environment Variables
    The tool allows the use of environment variables, enabling users to manage different environments effectively and switch between them easily.

Possible disadvantages of Thunder Client

  • Limited Advanced Features

    Unlike some other API testing tools, Thunder Client does not have built-in collaboration features, which can limit its use in team environments.

    It is primarily designed for use within Visual Studio Code, which may not be ideal for users who work across multiple platforms or require a standalone solution.
