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.

PHP Sandbox features and specs

Ease of Use
PHP Sandbox provides a user-friendly interface for developers to quickly test and experiment with PHP code without the need to set up a local environment.
Instant Setup
Users can start coding immediately without the hassle of server configurations or software installations, which accelerates the coding and testing process.
Collaboration
The platform allows for easy sharing and collaboration, enabling developers to work together on projects in real-time.
Cost-Effective
By using PHP Sandbox, developers can save on costs associated with setting up and maintaining local or cloud-based development environments.

Possible disadvantages of PHP Sandbox

Limited Resources
Compared to a full-fledged server environment, PHP Sandbox may have limitations in terms of processing power and available memory.
Restricted Environment
The sandboxing nature means some PHP extensions or functions may not be available, which could restrict certain testing scenarios.
Internet Dependency
An active internet connection is required to use the platform, which could be a disadvantage in areas with unreliable connectivity.
Security Concerns
Running code in an online environment can pose security risks, as sensitive data might be exposed if proper precautions are not taken.
