Show HN: SnapConfig – Superfast config loader for Python, powered by Rust
github.comI built snapconfig because loading large configs across AI worker processes was too slow.
Inspired by uv's use of rkyv, snapconfig compiles JSON/YAML/TOML/INI/env files to a binary cache, then memory-maps them for zero-copy reads. Cold loads are slower than Python's json module, but cached loads are 10-1000x faster. Benchmark results are available on github repo.
Perfect for Celery workers, serverless functions, AI workflows, or any setup where multiple processes read the same config.
