Its core promise is direct access to serialized data without a separate parsing or unpacking step while preserving forwards and backwards compatibility. ### Project history The public repository began in January 2014, followed by a v1.0.0 tag in June 2014. The project centers on the flatc compiler, schemas, generated language code, and runtime libraries rather than a single runtime format implementation. ### Adoption history FlatBuffers broadened from C++ into a multi-language serialization ecosystem. The official README lists code generation and runtime support for languages including C, C++, C#, Dart, Go, Java, JavaScript, Kotlin, Lua, PHP, Python, Rust, Swift, TypeScript, and others, with package surfaces on registries such as NuGet, pub.dev, go.dev, Maven, npm, PyPI, crates.io, and Swift Package Index. ### How it is used The documented workflow is to write a .fbs schema, build or install flatc, generate language-specific code, serialize data with generated builders, and read buffers through generated accessors. The package manager executable flatc is therefore central to most FlatBuffers workflows. ### Why package nerds care FlatBuffers is significant because one source package feeds many language package ecosystems. It combines a native compiler, schema files, generated code, and runtime libraries, and its README explicitly notes that the project uses date-style versioning rather than traditional SemVer. ### Timeline - 2014: Initial public repository and FlatBuffers code commit. - 2014: v1.0.0 release tag. - 2021: v2.0.0 release tag. - 2025: v25.2.10 release tag using the date-style versioning scheme. ### Related projects - The official README points to language-specific FlatBuffers packages and ecosystems, while flatc is the compiler used to generate language bindings from schemas. ### Sources - - - - ## Security Notes No matching local secret-handling manifest was found for flatbuffers.
