Open Source Elixir Communications Software for Linux

We have applied the lessons learned from projects like Plug, Ecto and Phoenix in designing clean and composable APIs, with clear separation of concerns between modules. Swoosh comes with many adapters, including SendGrid, Mandrill, Mailgun, Postmark and SMTP. Compose, deliver, and test your emails easily in Elixir. Swoosh supports the most popular transactional email providers out of the box and also has an SMTP adapter. Adding new adapters is super easy and we are definitely looking for contributions on that front. Get in touch if you want to help! Check the documentation of the adapter you want to use for more specific configurations and instructions. Swoosh does not make any special arrangements for sending emails in a non-blocking manner. Opposite to some stacks, sending emails, talking to third party apps, etc in Elixir do not block or interfere with other requests, so you should resort to async emails only when necessary.

Swap out your queries, data fetching, and caching for bulletproof sync that just works. Electric syncs little subsets of your Postgres data into local apps and services. So you can have the data you need, in in-sync, wherever you need it. And you can level-up all the way to syncing into a local embedded PGlite database. With built-in persistence and live reactivity.

Bamboo is part of the thoughtbot Elixir family of projects. Flexible and easy-to-use email for Elixir. Built-in support for popular mail delivery services. Bamboo ships with adapters for several popular mail delivery services, including Mandrill, Mailgun, and SendGrid. It's also quite easy to write your own delivery adapter if your platform isn't yet supported. Deliver emails in the background. Most of the time you don't want or need to wait for the email to send. Bamboo makes it easy with Mailer.deliver_later. A functional approach to mail delivery. Emails are created, manipulated, and sent using plain functions. This makes composition a breeze and fits naturally into your existing Elixir app. Unit test with ease. Bamboo separates email creation and email delivery allowing you to test by asserting against email fields without the need for special functions. Dead-simple integration tests. Bamboo provides helper functions to make integration testing easy and robust.

Magnetissimo is a self-hosted Elixir-based web application that crawls and indexes multiple popular torrent sites and stores magnet links in a local database—designed to run without JavaScript and optimized for high performance using Elixir’s GenServer and the BEAM VM. No JavaScript frontend—relies entirely on server-rendered content. High performance via Elixir’s GenServer and BEAM concurrency model. Easy integration with tools like Sonarr and Radarr. Readable, maintainable, and lean codebase.

Erlang and Elixir make it very easy to send messages between processes even across the network, but there are a few pitfalls. Sending a message to many PIDs across the network also copies the message across the network many times. Send calls cost about 70 µs/op so doing them in a loop eventually gets too expensive. Manifold distributes the work of sending messages to the remote nodes of the PIDs, which guarantees that the sending processes at most only calls send/2 equal to the number of involved remote nodes. Manifold does this by first grouping PIDs by their remote node and then sending to Manifold.Partitioner on each of those nodes. The partitioner then consistently hashes the PIDs using :erlang.phash2/2, groups them by the number of cores, sends to child workers, and finally those workers send to the actual PIDs. This ensures the partitioner does not get overloaded and still provides the linearizability guaranteed by send/2.

Papercups is an open-source live customer support tool web app written in Elixir. We offer a hosted version at app.papercups.io. You can check out how our chat widget looks and play around with customizing it on our demo page. The chat widget component is also open-sourced. We wanted to make a self-hosted customer support tool like Zendesk and Intercom for companies that have privacy and security concerns about having customer data going to third-party services. Use Papercups to answer support tickets via email. Forward Twilio conversations and respond to SMS requests from Papercups. A customizable chat widget you can embed on your website to talk to your customers. Connect with Mattermost, so you can view and reply to messages directly from Mattermost. Connect with Slack, so you can view and reply to messages directly from a Slack channel.
