MemU is an open-source memory framework (by NevaMind-AI) that gives LLM-based agents and AI companions a persistent, cross-agent memory layer with source-linked recall and human-readable Markdown storage. Built for developers and teams running agents like Codex, Claude, and Cursor, it autonomously organizes, links, and evolves stored preferences, decisions, and learned skills so context and conventions follow you from one agent to the next. Its differentiator is a file-system-style, inspectable memory that is shared across agents/devices and designed to cut token costs for always-on agents rather than locking memory inside a single tool.

Sentry is the application monitoring platform loved by over 4 million developers and 100,000 organizations. From error tracking to performance monitoring and session replay, Sentry helps teams resolve issues faster and improve code quality.
