Zep

What it is for

Zep is a hosted context graph for agent memory: the official v4 quickstart still (see the cover: pip install zep-cloud and Initialize the Zep client) is the product. Use it when the job is store episodes and retrieve a Context Block on the next turn.

License is hosted commercial plus open-source Graphiti. Free prints 10,000 credits / month. Flex is the first public paid card.

What makes it unique: credits meter Episode ingestion only; retrieval, storage, threads, users, and graph storage print 0 credits on the same pricing page.

Key features

• Context Graph — users, threads, business data, and a retrieved Context Block (quickstart).
• Episode ingest — write a turn as an Episode the graph can recall later.
• Context Block — pull a ready-to-prompt memory blob on the next request.
• Context MCP Server — off-the-shelf agents share the same memory over MCP.
• Graphiti — temporal graph framework you can run beside the hosted API.
• Custom entity / edge types — teach the graph the nouns your product cares about.

Who it's for

Best fit: teams shipping agents that must remember users across sessions and will stay inside a monthly credit pool.
