Useful if you’re looking for the best way to generate and manage API documentation in your Elixir projects.

In this post, we dive into how to deploy Phoenix applications using Kamal: https://blog.appsignal.com/2025/06/10/deploying-phoenix-applications-with-kamal.html

Numbering a list is normally really easy - but it’s not obvious how to do it in LiveView for a nested form with <.inputs_for>

My new post explains how to do it, including an important extra consideration if your nested inputs are sortable: https://arrowsmithlabs.com/blog/numbering-nested-inputs-in-phoenix-liveview

A behind-the-scenes look at how Semaphore uses Elixir and a finite state machine to orchestrate thousands of CI/CD pipelines reliably and at scale.

After a great conversation with @joshcprice.bsky.social at ElixirConf EU about working with Excel files, I was inspired to create a wrapper for the excellent umya-spreadsheet Rust library.

Introducing umya_spreadsheet_ex — an Elixir wrapper that brings powerful Excel file manipulation to your projects!

You can do a lot with it — check it out!

✏️ With Phoenix 1.8, the authentication code generator inside phx.gen.auth has been revamped, favoring an emailed ‘magic link’ authentication flow.

In this blog post, I’ll give a visual tour of how this looks to the user, what the core schemas/contexts look like, and I’ll sprinkle in some personal commentary as we go.

I recently released a new error tracker Faulty, based largely on error_tracker, but instead of hosting your errors locally it sends them to the accompanying FaultyTower website. Errors are tracked from Logger and telemetry events, integrations are available for Phoenix, Plug, Oban and Quantum.
Installation is as simple as mix igniter.install faulty. The FaultyTower website allows you to create users, organizations and projects within those organizations. You can be notified of new errors by e-mail, integration with ntfy.sh or Github issues.
