Extremely simple, fast, efficient, cross-platform serialization format

In plain words

This is a cross-platform serialization format designed to be simple, fast, and efficient. It launched in 2020 and is available on GitHub. The tool is suitable for developers who need to serialize data across different platforms. Its main distinction is prioritizing simplicity and performance over complexity, making it accessible for projects that require reliable data exchange without unnecessary overhead.

  Apache Fory Rust – 10-20x faster serialization than JSON/ProtobufOct 2025 · fory.apache.org · ▲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:…

  Hexi – Modern header-only network binary serialisation for C++2025 · github.com · ▲118

  Over the last few years, I've needed an easy way to quickly serialise and deserialise various network protocols safely and efficiently. Most of the libraries that existed at the time were either quite heavy, had less than stellar performance, or were an abstraction level above what I was looking for. I decided to put together my own class to do the job, starting with an easy, low-overhead way to move bytes in and out of arbitrary buffers. Along the way, it picked up useful bits and pieces, such as buffer structures and allocators that made the byte shuffling faster, often being able to do it…

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  After 2.5 years on my side project, it has hit £500/month revenue▲647

  It's been a long slow hog and I almost gave up a few times (more than a few) but when covid hit this year it gave me some time to really focus on my product. There were stupid user journey things that I knew needed fixed. There were some features I knew needed added. And I knew the pricing was wrong. I spent some hardcore time working on these things back in March / April and since then my MRR has continued to grow. My product is SongBox (https://songbox.rocks) - it's an alternative to things like bandcamp and soundcloud for creators who need to share audio files privately.…
