history

Project history and usage

FlatBuffers is Google's cross-platform serialization library designed for maximum memory efficiency. 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.

security posture

No protected-tool coverage found yet

No matching local secret-handling manifest was found for flatbuffers. Nucleus package metadata is still published here so future coverage has a stable package URL.

Install behavior

  • No Homebrew post-install hook is recorded in formula metadata.
  • Homebrew bottle metadata is available for 6 platform targets.
  • Build metadata lists 1 build dependencies.

Recommended review

Before unattended agent use, check whether the tool reads plaintext credentials, writes remote state, publishes artifacts, or shells out to plugins.
