Charts with Plotto
Plotto is a 100% Elixir charting library with no NIFs or external dependencies. In this episode, we’ll use it to add interactive SVG charts to a Phoenix LiveView dashboard.
Doggo 0.15.0 released
Doggo is a headless component library for Phoenix LiveView. 0.15.0 adds hooks for 14 components to implement the APG patterns and contains plenty other improvements.
Release notes: https://github.com/woylie/doggo/releases/tag/0.15.0
SeedFactory v0.9.0 Released
This release has a new dependency planner. It searches for a complete plan and backtracks when a choice doesn’t work out, including deciding the order in which commands run.
SmolBox: running code in disposable microVMs from Elixir
I built SmolBox, an Elixir library for running programs in disposable microVMs through SmolVM workers, on Linux and macOS Apple Silicon.
This article walks through a Python example, from submitting work to collecting output files and confirming cleanup. It explains how execution continues independently of the submitting process, how stable execution identities work, and why SmolBox doesn’t silently rerun a command when its outcome is unknown.
Python is just the example. The same lifecycle supports JavaScript, TypeScript and other programs when the approved guest image includes the required runtime and dependencies.
I also explain why I chose SmolVM and when an embedded interpreter, local process or function platform might fit better.
How are you handling execution, results and cleanup when running code outside the BEAM?
Gleam Gathering 2027 next Feburary in London
Gleam Gathering is happening again on 27th of February 2027 in London, UK. Tickets sales are up and the Call For Talks is open. https://gleamgathering.com/ The first edition held last year in Bristol was great, even if we had to introduce a lot of people to the concept of Bristol. Come and meet the super friendly community, no surprises there coming from the BEAM.
ExIcon 1.0.0: Generic icon downloader and component generator
ExIcon is a generic and extensible icon set downloader and Phoenix LiveView icon component generator. It also works with SVGs in local folders, has various options to configure the generated attributes, and it is a dev-only dependency. Version 1.0.0 was recently released.
If it’s going to be read by a human, it should be written by a human
This article aims to show you why I hate AI prose. This includes an explanation of why the text LLMs produce is uniquely difficult to read and comprehend, and why it’s a burden and not a boon to human communication. Use LLMs to write code, by all means: but please, don’t use them to write prose.

ReqCircuitBreaker: Circuit breaker using Fuse for Req
ReqCircuitBreaker is a new circuit breaker plugin for Req that uses Fuse under the hood.
Finding Your Broken Glass: A Flaky Test Prompt for GitHub Actions
✏️ CI goes red on a test you never touched, so you click re-run and hope. Nobody on the team can say how often that happens or what it costs.
Your GitHub Actions history already knows. I wrote a prompt that reads it, names the confirmed flakes, and puts an annual dollar figure on the re-runs. Plus the usual Elixir causes to look for.

ReqSSRF: SSRF protection for Req
ReqSSRF is a new package for preventing SSRF vulnerabilities when making requests to user-provided URLs with Req.
SafeRedirect: Redirect URI validation for preventing open redirects
We just open-sourced SafeRedirect, a new package for validating, resolving, and redirecting to user-provided URIs to prevent open redirect vulnerabilities.

Aurora Meter: real-time usage metering and plan entitlements for Phoenix
A free MIT library that counts usage on an ETS hot path (no DB on the write path), gates features by plan with an atomic with_quota/4, and renders live usage in LiveView over PubSub, Syncs with Stripe.

Texttile: a multiplayer blog engine in Phoenix and LiveView
My wife and I write a travel blog together. Every day, photos and videos had to move from one phone to the other before we could sort them into a post.
So I wrote Texttile. Multiple people can work in the same entry: one writes, the other follows live and arranges the gallery. Phoenix, LiveView and SQLite run in one Docker container. Photos and videos stay on your server, with no YouTube embeds.
The story, with a video of two people editing together: https://www.v01.io/posts/2026/08/texttile/
Demo: https://www.texttile.blog Source: https://github.com/texttile-blog/texttile
I’d love feedback from people who have built collaborative interfaces with LiveView.
Obscura 0.2.0: spaCy NER for Elixir on the CPU
Obscura 0.2.0 introduces :efficient, combining deterministic PII recognizers with spaCy NER for English names and locations.
Inference runs in a local Rust executable through an Erlang Port, with supervised workers and no Python required at runtime. It supports Linux servers and Apple Silicon macOS development.
On 5,000 heldout synthetic documents, it recovered more exact PII spans than :fast, but also produced more false positives. The article explains that tradeoff, CPU workload results, and why higher F1 doesn’t necessarily mean better privacy protection—with installation and Elixir integration examples.
Feedback and synthetic failure cases are welcome!

Build It With Phoenix is now Pay What You Want!
As of today (in time for @ElixirConf), my @ElixirLang and @ElixirPhoenix video course, Build It With Phoenix, is pay what you want! $0 is a legitimate option. Thank you to the 150+ of you that purchased it previously—you have made this possible. Keep learning!!!
One Pipe, One User Story: The Case for phoenix_test
✏️ Phoenix’s built-in LiveView test helpers require you to hand-build the form payload and start a fresh pipe after every click. Worse, that payload means a test can pass even when the button it “submits” was renamed.
phoenix_test writes the entire flow as a single pipe from the user’s point of view and fails with a focused error instead of the entire page’s HTML. I used it on my last side project, and I don’t want to turn back.

Building a Phased Microkernel Compiler in Elixir: How We Tamed Dependency Graphs in JusrisOS
Someone say useful.
However, as the system grew, standard compilation (mix compile.elixir) presented two distinct structural problems:
