   Gosax – A high-performance SAX XML parser for Go▲76

   I've just released gosax, a new Go library for high-performance SAX (Simple API for XML) parsing. It's designed for efficient, memory-conscious XML processing, drawing inspiration from quick-xml and pkg/json. https://github.com/orisano/gosax Key features: - Read-only SAX parsing - Highly efficient parsing using techniques inspired by quick-xml and pkg/json - SWAR (SIMD Within A Register) optimizations for fast text processing gosax is particularly useful for processing large XML files or streams without loading the entire document into memory. It's well-suited…

    Apache Fory Rust – 10-20x faster serialization than JSON/Protobuf▲67

    Serialization framework with some interesting numbers: 10-20x faster on nested objects than json/protobuf. Technical approach: compile-time codegen (no reflection), compact binary protocol with meta-packing, little-endian layout optimized for modern CPUs. Unique features that other fast serializers don't have: - Cross-language without IDL files (Rust ↔ Python/Java/Go) - Trait object serialization (Box) - Automatic circular reference handling - Schema evolution without coordination Happy to discuss design trade-offs. Benchmarks:…

    gq – like jq or zq, but you use Go▲107

    Hi HN. I've gotten pretty tired of needing to learn a custom programming language for a tool I use once a week or less. So I figured, it might be easier to pick up if `jq` used a programming language I already know. Voila, gq.

    A new stdlib for Golang focusing on platform native support▲154

    No gc, No goroutines, Produces small binaries while using the unmodified official go toolchain, and comes with complete Web SDK (generated from w3c/webref). We are building `pcz` to provide a reimagination of Go the language, in an effort to make it suitable for all kinds of programming tasks, and currently you can use it to build efficient web applications in Go using the generated Web SDK (as shown with the live web demo[1]). The journey is just starting, any suggestions? or any critics? [1]: https://primecitizens.github.io/livedemos/10-plat-web/

    Gonzo – A Go-based TUI for log analysis (OpenTelemetry/OTLP support)▲74

    We built Gonzo to make log analysis faster and friendlier in the terminal. Think of it like k9s for logs — a TUI that can ingest JSON, text, or OpenTelemetry (OTLP) logs, highlight and boil up patterns, and even run AI models locally or via API to summarize logs. We’re still iterating, so ideas and contributions are welcome!

    - What's different? It's fast. On my machine, the stream decoder is faster than bytedance/sonic which claim to be the fastest even though mine is written in pure Go and Sonic is written in Go + C + Assembly. It also is a drop-in replacement of the standard library. - Why is it fast? technologies used are in my articles (available in English and Japanese) EN: https://sugawarayuuta.medium.com/still-i-wanted-to-build-the...
