ByteRover gives coding agents long-term, structured memory that persists across sessions and tools. It organizes project knowledge into hierarchical context trees, stores them locally by default, and serves relevant context back to agents through an MCP server and CLI. It plugs into Cursor, Claude Code, Windsurf, and other assistants, and an optional cloud tier lets teams sync and share context.

Pros & cons

  • Local-first, no telemetry by default
  • Works across Cursor/Claude Code/Windsurf
  • Source-available CLI (Elastic 2.0)
  • Free-forever tier
  • Source-available, not OSI open source
  • Younger than general-purpose memory APIs
  • Cloud sync and team sharing are paid

    Mem0

    Long-term memory layer for AI agents. Self-hostable.

    Persistent memory store + retrieval pipeline for agent applications. Handles per-user/per-session/per-agent scope cleanly; pairs with OpenAI, Anthropic, and local models.

    Worth knowing

    A YC S24 company that pivoted from the Embedchain RAG framework; raised a $24M Series A from YC and Peak XV in 2025.

    Supermemory

    Supermemory

    Memory API that gives any AI agent long-term recall.

    Supermemory is a memory and context engine for AI apps. It ingests documents, chat histories, and connector data (Drive, Gmail, Notion), turns them into a searchable store, and serves relevant context back to agents over a single API. It works with any model and ships an MCP server alongside official SDKs.

    Worth knowing

    Built by 19-year-old Dhravya Shah; its $2.6M seed was backed by Google AI chief Jeff Dean and Cloudflare execs.

    Zep

    Zep

    Temporal knowledge-graph memory for AI agents.

    Memory layer that gives agents long-term context by building a temporal knowledge graph from chat history and business data, tracking how facts evolve over time. It's powered by Graphiti, Zep's Apache-2.0 open-source temporal graph engine, with Zep Cloud offering a managed, credit-based service on top. Used to keep agent context relevant as conversations and data grow.

    Worth knowing

    A YC W24 startup; published a 2025 arXiv paper benchmarking its temporal knowledge-graph memory against prior agent-memory work.

    Cognee

    Open-source memory for AI agents.

    An open-source semantic memory layer for AI agents. Cognee ingests documents, relational data, and system context, then runs an Extract-Cognify-Load pipeline that uses an LLM to build a knowledge graph with embeddings and relationships. Agents query it for durable, cross-session context that captures how concepts connect. Self-host the Python SDK for free, or use the managed cloud tiers.

    Worth knowing

    Berlin-based; raised a $7.5M seed in Feb 2026 led by Pebblebed (run by OpenAI and FAIR co-founders).
