memvid

What it does

Bundles data, embeddings and search structure into a single versioned file, so long-term memory travels with the agent instead of requiring a database to stand up alongside it. Retrieval is fast and the file can simply be handed to another environment. The published accuracy and latency gains are the project's own benchmarks, worth reproducing on your workload. Note the flip side of portability: one file leaking means the entire memory leaks. Apache-2.0.
