A tiny, primitive, fast HTTP request/response parser written in C, designed to be stateless and memory-efficient.
PicoHTTPParser is a lightweight HTTP/1 parser written in C, designed to parse HTTP requests and responses quickly and efficiently. It solves the need for a fast, minimal parser that doesn't allocate memory or maintain state, making it ideal for high-performance networking applications.
Developers building web servers, proxies, or networking tools in C or languages that can bind to C libraries, especially those prioritizing speed and low memory overhead.
Developers choose PicoHTTPParser for its exceptional speed, simplicity, and reliability—it's battle-tested in production environments like H2O and popular Perl modules, offering a no-nonsense parsing solution without the bloat.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Does not maintain internal state, making integration flexible and straightforward, as evidenced by its use in diverse systems like H2O and Perl modules without side effects.
Operates entirely on provided buffers, eliminating dynamic memory management overhead and preventing leaks, which is critical for high-performance and embedded applications.
Optimized for performance with benchmarks shown in the README, and trusted in production servers like H2O for its efficient parsing, making it ideal for latency-sensitive systems.
Exposes only four functions (e.g., phr_parse_request, phr_decode_chunked), reducing complexity and learning curve, as demonstrated in the clear usage examples.
Only supports HTTP/1, with no built-in handling for HTTP/2 or newer versions, restricting its use in modern web environments that require multi-protocol support.
Requires the caller to manage buffers and state, which can lead to errors like buffer overflows if not handled carefully, increasing development complexity and risk.
Focused on speed, it may not validate all aspects of HTTP messages (e.g., malformed headers), potentially missing security vulnerabilities that need additional checks.
