Convincing case for SQLite over Postgres for single-node agent memory.

Strengths
  • •Concrete benchmarks comparing latency and overhead for realistic agent workloads.
  • •Eliminates Docker and connection pool complexity for local development setups.
  • •ACID transactions ensure text and embedding data stay strictly synchronized.
Weaknesses
  • •Limited utility for developers already committed to networked multi-agent clusters.
  • •SDK wrapper around SQLite doesn't add significant value beyond the blog post.

Post Description

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.

Lore – Cross-Agent Memory SDK (Python and TypeScript)

Local-first design — SQLite plus on-device ONNX embeddings — provides a small-footprint way to share operational lessons between agents, and automatic PII redaction is a thoughtful, tangible safeguard. The one-line publish/query API, cross-language SDKs (Python + TypeScript), and a planned FastAPI/Postgres+pgvector server show practical engineering trade-offs rather than vaporware.
