PyByteBuffer
A bytes manipulation library inspired by Java ByteBuffer
Decision gist · record as of 2026-08-14
No, unless you have a specific legacy requirement. The package is abandoned and will not receive updates or security patches. For new projects, use Python's built-in capabilities for byte manipulation, which are actively maintained. The copyleft GPL 3.0 license also restricts use in proprietary code.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is straightforward with no runtime dependencies.
- However, the package is abandoned—last commit was 2020-10-25 and no releases since 2020-12-28.
- It remains compatible with modern Python versions but will receive no maintenance or security updates.

What it is and what it does
PyByteBuffer is a bytes manipulation library modeled after Java's java.nio.ByteBuffer. It wraps Python's byte handling to provide a familiar API for developers coming from Java, with methods to allocate buffers, write and read data at a tracked position, and control endianness during conversions. The library handles single bytes, byte arrays, strings, and multi-byte integers with explicit byte-order specification.
The package has no external runtime dependencies and installs cleanly, but it is no longer maintained. The last commit was 2020-10-25, and no updates have been released since 2020-12-28. While it may still work on current Python versions, it will not receive bug fixes, security patches, or compatibility updates for future Python releases.
Use it for
- Porting Java code that uses ByteBuffer to Python while preserving the original API and logic
- Implementing binary protocol parsers or network packet handlers that require precise byte-order control
- Building low-level serialization or deserialization routines for binary file formats
- Prototyping or learning byte-level data manipulation with a familiar Java-style interface
