SQLite Is Enough for Local AI Agent Memory

About

hi HN,While building Wolbarg (an open-source shared memory SDK for AI agents), I assumed PostgreSQL would be the obvious choice for memory storage.After benchmarking SQLite under realistic agent workloads, I was surprised by the results. For local-first and single-node deployments, SQLite handled far more than I expected while keeping the architecture much simpler.I wrote up the benchmarks, methodology, trade-offs, and where I still think PostgreSQL is the better choice.
