deja-vu vs MemWhale

deja-vu: Deja-vu is a zero-dependency, local-first binary that indexes and makes searchable the historical sessions of various AI coding agents. It acts as a universal memory layer, allowing agents to recall past solutions and context efficiently, even from before its installation.; MemWhale: MemoryWhale is a local-first persistent debugging memory system for developers and coding agents. It records commands, output, failures, and fixes into a local SQLite database, allowing recovery of development history across sessions and tools without relying on hosted services.
