Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability. Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging. Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance. OTP is set of Erlang libraries and design principles providing middle-ware to develop these systems. It includes its own distributed database, applications to interface towards other languages, debugging and release handling tools. Erlang/OTP is available as pre-built binary packages by most OS package managers. You can use Kerl, a script that lets you easily build Erlang with a few commands. We take security bugs in Erlang/OTP seriously. The Erlang distribution includes a step-by-step getting started guide.

hackney is an HTTP client library for Erlang. No message passing (except for asynchronous responses): response is directly streamed to the current process and state is kept in a #client{} record. Binary streams, SSL support, keepalive handling, basic authentication. Stream the response and the requests, fetch a response asynchronously, multipart support (streamed or not), and chunked encoding support. It can send files using the sendfile API. Optional socket pool, REST syntax, hackney, Method(URL) (where a method can get, post, put, delete, ...)

Engineered to scale and last, æternity is an easily accessible blockchain platform for the global public. With numerous innovative functionalities and performance far ahead of earlier blockchains, æternity allows its users and community to seamlessly venture into the new era of society, economy, and digital interactions. The æternity blockchain project was born out of a desire for a more fair Internet supported by scalable, open-source and cryptographic software, with a commitment to technical excellence. æternity blockchain itself launched as the public æternity mainnet in 2018. It is now a blossoming community of enthusiasts supported via the æternity crypto foundation. At its core, æternity is a blockchain protocol and a smart contract platform that goes beyond what traditional blockchains do. It is designed to be fault-tolerant and perfect for cases with billions of transactions in DEFI and more.

Zotonic is the content management system and framework for semantic data and high-connectivity websites. Your data outlives your website. Grow your data and share your data. The Zotonic content management system excels in managing structured data from multiple sources. It brings structure to your documents and makes semantic data manageable for normal humans. Real-time connectivity is deeply integrated using the Internet of Things publish/subscribe protocol MQTT. You can rapidly develop CMS-based sites on top of Zotonic. If you need more flexibility, you can customize all aspects of Zotonic. The included web server means can start working with Zotonic right away, without the need for installing Apache or Nginx separately. Zotonic is structured into modules. Each module offers a specific piece of functionality; the CMS is itself a module. There are modules for access control, social media integration, TLS, video embeds and much more.

CloudI is an open-source private cloud computing framework for efficient, secure, and internal data processing. CloudI provides scaling for previously unscalable source code with efficient fault-tolerant execution of ATS, C/C++, Erlang/Elixir, Go, Haskell, Java, JavaScript/node.js, OCaml, Perl, PHP, Python, Ruby, or Rust services. The bare essentials for efficient fault-tolerant processing on a cloud!

Popcorn is an experimental library that allows Elixir code to run locally in the browser with JavaScript interoperability. It is intended for developers who want to explore client-side Elixir workflows without relying entirely on server-side execution. The project is still early and may introduce breaking changes, so it is best suited for experimentation, prototypes, and research rather than stable production use. Popcorn connects Elixir’s programming model with browser-based execution, opening the door for local interactive experiences and future LiveView-style ideas. It is useful for developers interested in WebAssembly, local-first interfaces, and alternative ways to build browser applications. Its main value is exploring what Elixir development can look like when part of the application logic runs directly on the client.

The ERDialog project offers a simple browser framework for small projects written in Erlang. Written applets include a bittorrent client, address book, text editor, AI experiments and graphics and music applications.

Scalaris is a scalable, transactional, distributed key-value store. It was the first NoSQL database, that supported the ACID properties for multi-key transactions. It can be used for building scalable Web 2.0 services. Scalaris uses a structured overlay with a non-blocking Paxos commit protocol for transaction processing with strong consistency over replicas. Scalaris is implemented in Erlang.

Erlang OPENGL/SDL api and utilities.

Resource pool project is written in Erlang as a tiny library. The goal of the tool is reduce the overhead of creating new resources by reusing of the same resources among multiple processes. Achieving result is better performance and throughput. The resource pool was inspired by Java Apache's commons pool and adopts API and main principals from this project. Database connection is most popular example for pooling resource.

MQTT client is designed for communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts and implements MQTT protokol versions 3.1 and 3.1.1. The client is written in Erlang and tested with MQTT servers like Mosquitto and RabbitMQ.

ErlMySQL is a MySQL client written in Erlang and provides API that is very close to Connector/C library. The client is using low level (TCP/IP socket) connection to MySQL server and allows to exchange a data with maximum possible speed. Multiple datasource support and connection pool are incapsulated in the client that increases a performance in concurrent environment.

Meter Data Management written in Erlang -- This is an experiment based on use cases that I know well. Erlang should work well for real-time metering.

Modern software systems and application are commonly written in multiple languages, include scripting engines, and are frequently build on multiple specialized frameworks and middleware for a considerable diversity of runtime environments. The latest influencing update in development paradigm is the application of multicore processors. This projects is aimed to unify the required trace and logging output and integrate into debugging environments. The target is to provide general development, test, and production support of software environments based on multiple programming languages for distributed multicore environments.
