ruby-mcp-client: An MCP (Model Control Protocol) Client Library — We’ve recently highlight Fast MCP which provides a way to create MCP servers from Ruby – this project provides the other angle, giving you a way to use MCP servers, such as an AI agent would. Even if you don’t use AI, this could provide an interesting alternative to certain APIs.

HUGLO: A Forthcoming Hyper-Ultra-Giga Low-Overhead Tracing Profiler — A tracing profiler that captures function calls, system calls, thread state changes and GC activity with overhead “low enough for continuous use in large-scale production systems.” It’s not open source yet but Matt says if there’s enough interest he’ll consider it..

Itsi: A Fast, New Ruby Rack Server — Itsi is an interesting new player joining the world of Ruby app servers. It’s written in Rust, is Rack compliant, and works as a reverse proxy, API gateway and static file server. You can choose between a typical blocking model, an (optional) fiber-based scheduling approach, or even mix the two in a hybrid model.

📊 Ruby Gem Analytics Powered by ClickHouse and Ruby Central — How would you like to quickly run SQL queries to do analytics over every single Ruby gem download since 2017? Now you can. There’s a lot of interesting data in here, and it’s a fascinating collaboration to boot.

Rails Is Super Easy to Upgrade … — … as long as you're on 6.0 or higher. You don't need to pay a retainer to keep Rails up-to-date, but if you're stuck on Rails 5, 4, or 3, or a custom fork of 2 (we’ve seen it!) you might need help getting over the hump. Ready to enter the 2020s?

Inline RBS Comments Support for Sorbet — The story of how engineers at Shopify added support for inline RBS typing comments to the Sorbet static type checker. It’s still experimental but could hugely improve the DX of using types.

Creating Beautiful Charts with JRuby and JFreeChart — One of the biggest wins of using JRuby is the direct access you get to established, mature libraries used in the Java ecosystem. Here’s an example of taking advantage of that by using JFreeChart to render graphs, but you could use the same technique with many other Java libraries too.

Streaming LLM Responses with Rails: SSE vs. Turbo Streams — If you want to get the results of LLMs into the hands of users ASAP, streaming is the way to go, but in a Rails app there’s more than one way to pull it off..

Sharding a Real Rails App (Mastodon) with PgDog — PgDog is a Postgres proxy server that can be used to shard data and route queries appropriately.

The Ultimate Guide to Scaling Sidekiq — Ooooh, pretty diagrams! Yeah I made them myself and I think they’re quite nice.

🚀 Need to Upgrade to Rails 8.0 and Ruby 3.4 but Not Sure How? — Your 0-downtime upgrade journey begins with a Roadmap. Know how long it will take before you begin.

🤖 Raif: An AI Framework in a Rails Engine — There are many Ruby libraries for interacting with LLMs and AI APIs now, but Raif goes a step further with a web-based admin interface and some abstractions around tasks, conversations, creating agents, and embedding generation that integrate into Rails apps in an idiomatic way.

Ruby 3.5.0 Preview 1 Released — Christmas Day may be eight months away, but it’s time to start counting the days to Ruby 3.5’s eventual release with this initial preview version. The updates are far less significant than for 3.4 so far, but if you’re a library developer, it’s worth putting it through its paces early.

🚀 FastRuby.io Makes Your Rails Upgrade Delightfully Boring with Bonsai — FastRuby.io’s monthly maintenance service keeps uptime high and costs low (starting at $4,000/month). The team behind next_rails offers Bonsai for gradual, 0-downtime upgrades — making upgrading Ruby and Rails feel delightfully boring.

JRuby 10.0 Released — Before Easter, we mentioned the imminent release of JRuby 10, the latest Ruby 3.4-compatible version of the high performance JVM-based Ruby implementation which Charles Oliver Nutter explained in depth here. It’s now out, for real, and marks a huge leap forward for the project.

mruby 3.4.0 Released — mruby began life about ten years ago as an alternative lightweight standards-compliant Ruby implementation (led by Matz himself) with a focus on being both small and embeddable. v3.4 adds private and protected support and several new hooks.

Extracting Deprecation Warnings from Rails' Source Code — While FastRuby does this to improve their Rails upgrade services, you could use similar techniques for all sorts of Ruby source processing shenanigans.

Because Reading Error Logs Is Not a Hobby — When *$!% breaks, you want to quickly understand and fix it—not sift through logs for the next hour. Learn how Honeybadger can help →

TableTennis: Print Stylish Tables at the Terminal — A Ruby library for printing tabular data in the terminal that includes theming (e.g. light or dark), automatic layout, automatic formatting of dates and numbers, coloring for numeric values, and more.

Introducing Herb: A New HTML-Aware ERB Parser for Smarter Developer Tooling — Herb was created to help view-based tooling catch up with the rest of the Rails tooling stack. It’s written in C, so it’s suitable for real-time development, and it comes with a slick playground so you can see it in action.

Errbit: A Self Hosted Error Catcher — If you want to catch and manage errors from production apps in a structured way, this is for you. It’s compatible with the Airbrake API so you can use the existing airbrake gem with it.

📅  Ruby Events: 6,000+ Talks from 200+ Ruby Events — Formerly known as Ruby Video, this mammoth repository of Ruby videos and event information is only getting better and better. The goal is to index all Ruby events, and their talks, and make it easier to look through them.

Introducing MonkeysPaw: A Prompt-Driven Web Framework in Ruby — You probably won’t be rolling this into production any time soon, but MonkeysPaw explores the curious idea of just writing pages as prompts and then letting a large language model just get on with it(!)

Let There Be Docs: Generating an OpenAPI Schema Across the Rails Stack — Do you prefer to write API docs first or start with the implementation? For the latter, it’s possible to use Typelizer and RSwag to automatically extract type info from serializers, controllers, and the database that stays synchronized with the implementation.
