The open-source work behind our engineering.

Selected open-source work by Benoît Chesneau, including projects supported through Enki Multimedia, grouped by what each one demonstrates. Unless an entry says otherwise, Benoît is the author and current maintainer. The full list is on GitHub.

Python infrastructure

Serving Python applications in production, down to the HTTP parser.

GunicornThe Python WSGI HTTP server. Author, maintained. gunicorn_h1cFast HTTP/1.1 parser for Gunicorn, SIMD-optimised. http-parserHTTP parser for Python, written in C.

The Erlang HTTP and network stack

Livery, Hackney, erlang_h1, erlang_h2, erlang_quic and erlang-webtransport form one stack, from the HTTP framework down to QUIC. See the stack diagram

HackneyErlang HTTP client, now up to HTTP/3. Author, maintained. LiveryHTTP server framework over HTTP/1.1, 2 and 3. erlang_quicQUIC transport and HTTP/3 in pure Erlang. erlang_h2HTTP/2 protocol library. erlang_h1HTTP/1.1 client and server. erlang-webtransportWebTransport over HTTP/2 and HTTP/3. erlang_wsWebSocket, RFC 6455, 8441 and 9220. livery_grpcgRPC server and client on Livery. erlang_masqueMASQUE tunnels over HTTP.

Erlang/OTP distribution

Prebuilt Erlang/OTP packages for Linux, macOS and Windows, built from the upstream erlang/otp releases.

Despite its name, erlang-dist is not about Erlang distribution (clustering), and it is not a new runtime.

Help with OTP upgrades and builds, if you want it

erlang-distAPT and DNF repositories, tarballs and a Windows installer, with SHA256 checksums. Builds follow erlang/otp releases. Installation guideInstall commands, platforms and versions, maintained with the project.

Distributed systems

Membership, NAT traversal and transport for nodes spread across networks.

erlang-natNAT handling for Erlang applications. estunSTUN client for NAT traversal. erlang-derpDERP relay protocol in Erlang.

Runtimes and language interoperability

Python and JavaScript running inside Erlang systems.

erlang-pythonPython from Erlang, GIL-aware. HornbeamPython WSGI and ASGI applications on the BEAM. erlang-quickjsQuickJS JavaScript engine for Erlang. erllamallama.cpp runtime for Erlang. Experimental.

WebAssembly

Sandboxed, embedded execution and extension systems for Erlang applications. What it is used for

erlang_wasmA WebAssembly runtime implemented in Erlang/OTP. erlang-wasmtimeWasmtime bindings; guests can call Erlang. wasm_demoExample project using erlang_wasm.

Database & storage engineering

Document databases, replication and embedded storage. Database & storage engineering

Apache CouchDBFormer committer and PMC member; donated rcouch. CouchbeamCouchDB client for Erlang. Author, maintained. erlang-rocksdbErlang bindings for RocksDB. Author and maintainer since 2016; professional support from Enki Multimedia.

Observability and development tools

Production telemetry for Erlang, and small libraries many Erlang projects depend on.

instrumentOpenTelemetry-compatible traces, metrics and logs for Erlang, with OTLP and Prometheus export. hooksPlugin and hook system for Erlang applications. mimerlMIME types library, a Hackney dependency.
