Hound is an Elixir library for browser automation and integration testing. It wraps the WebDriver protocol, allowing developers to write ExUnit tests that control browsers like Firefox, Chrome, or PhantomJS via Selenium or ChromeDriver. Hound supports parallel sessions, asynchronous test execution, JavaScript-heavy interactions, screenshots, and more—all directly in Elixir test suites.

Wallaby helps you test your web applications by simulating realistic user interactions. By default, it runs each test case concurrently and manages browsers for you. Here's an example test for a simple Todo application. Because Wallaby manages multiple browsers for you, it's possible to test several users interacting with a page simultaneously. Read on to see what else Wallaby can do or check out the Official Documentation. Wallaby also requires bash to be installed. Generally, bash is widely available, but it does not come pre-installed on Alpine Linux. If you're testing a Phoenix application with Ecto and a database that supports sandbox mode, you can enable concurrent testing by adding the Phoenix.Ecto.SQL.Sandbox plug to your Endpoint. It's important that this is at the top of endpoint.ex before any other plugs.

This library can be configured to handle encoding and decoding requests and responses automatically based on the accept and/or content-type headers. An Elixir OAuth 2.0 Client Library. This library can be configured to handle encoding and decoding requests and responses automatically based on the accept and/or content-type headers. The http client library used is tesla, the default adapter is Httpc, since it comes out of the box with every Erlang instance but you can easily change it to something better.

Plausible is lightweight and open-source web analytics. No cookies and fully compliant with GDPR, CCPA and PECR. Made and hosted in the EU, powered by European-owned cloud infrastructure. Frustrated with Google Analytics? So are we and that's why we built Plausible Analytics, a simple, lightweight (< 1 KB), open source, and privacy-friendly alternative that doesn't come from the adtech world. Web analytics went from a simple, fun and useful practice for site owners to a data-grabbing machine for surveillance capitalism. Google Analytics is frustrating to use, difficult to understand, slow to load and privacy-invasive too. Plausible Analytics is built for privacy-conscious site owners. You get valuable and actionable stats to help you improve your efforts while your visitors keep having a nice and enjoyable experience. Plausible is simple analytics. It is easy to understand and it cuts through the noise.

Beacon is a modern open-source CMS built with Phoenix LiveView, offering fast server-rendered HTML for content-heavy pages with LiveView interactivity layered on top. It includes runtime content reloading, SEO-optimized rendering, and an admin interface (Beacon LiveAdmin) for managing pages, layouts, and components in a cluster-friendly setup. Developed by DockYard, Beacon aims to deliver high performance content sites fully within the Elixir ecosystem.

HTTP client for Elixir, based on HTTPotion. HTTPoison uses hackney to execute HTTP requests instead of ibrowse. Using hackney we work only with binaries instead of string lists. First, add HTTPoison to your mix.exs dependencies. Add :httpoison to your applications list if your Elixir version is 1.3 or lower. You can also easily pattern match on the HTTPoison.Response struct. There are a number of supported options(not to be confused with the HTTP options method), documented here, that can be added to your request. The example below shows the use of the :ssl and :recv_timeout options for a post request to an api that requires a bearer token. The :ssl option allows you to set options accepted by the Erlang SSL module, and :recv_timeout sets a timeout on receiving a response, the default is 5000ms.

Static Site Generator for Elixir.

The flexible HTTP client library for Elixir, with support for middleware and multiple adapters. Tesla is an HTTP client loosely based on Faraday. It embraces the concept of middleware when processing the request/response cycle. Define module with use Tesla and choose from a variety of middleware. Tesla is built around the concept of composable middlewares. This is very similar to how Plug Router works. All HTTP functions, such as Tesla.get/3 and Tesla.post/4, can take a dynamic client as the first argument. This allows using convenient syntax for modifying the behavior in runtime. Tesla supports multiple HTTP adapter that do the actual HTTP request processing. Each piece of the stream will be encoded as JSON and sent as a new line (conforming to JSON stream format). You can set the adapter to Tesla.Mock in tests.

Crawly is a high-level application framework for crawling websites and extracting structured data using the Elixir programming language. It provides a complete environment for building web crawlers that systematically visit pages, collect information, and transform that data into structured formats for further processing. Crawly is designed for tasks such as data mining, information processing, and building historical archives of web content. Crawly follows the Elixir and OTP architecture model, enabling concurrent and fault-tolerant crawling processes that can handle many requests efficiently. Developers define specialized components called spiders to control how pages are visited and how information is extracted from them. It also supports extensibility through middlewares, pipelines, and fetchers that allow customization of request handling, data processing, and crawling behavior.

Firezone is a modern, self-hosted VPN solution built on WireGuard, designed to provide secure remote access for teams and infrastructure. It offers a sleek web interface, automatic configuration management, and strong encryption. Unlike traditional VPNs, Firezone focuses on ease of deployment, scalability, and integration with identity providers, making it ideal for developers and teams needing secure networking without relying on third-party services.
