harrow is a thin HTTP framework built directly on Hyper 1.0. The goal is explicit, macro-free routing with built-in observability: tracing spans, Prometheus metrics, and structured request IDs from the start, not bolted on after the fact.
ro11y is a Rust observability library that implements OTLP protobuf export over HTTP without pulling in the full OpenTelemetry SDK. Seven direct dependencies instead of a hundred and twenty. It builds on the tracing crate for structured logging and distributed tracing.
marie-ssg is a static site generator built to do one thing well: turn markdown files paired with TOML metadata into HTML pages. It powers this site. The design prioritizes build speed, minimal configuration, and staying out of the way.
qrst is a hybrid search engine that runs entirely on-device. No API calls, no cloud, just a Rust binary and an embedding model. It combines BM25 keyword search (SQLite FTS5) with vector semantic search (ONNX embeddings + HNSW) and fuses results using configurable strategies including Reciprocal Rank Fusion and learned-to-rank models.
