Building Software with Ruby On Rails

[José Valim @josevalim]

Elixir v1.20 released! Now officially a gradually typed language: Elixir type checks every single line of code, finding bugs and dead code, without developer overhead (no typing signatures) and extremely low false positives rate. Plus a faster compiler! Links and reports below.

Woot! The Tidewave gem for Rails has crossed 1M downloads: https://t.co/WK44NEvlmo

https://t.co/KNZbk8apeI is the best way to use coding agents for building web applications and we will have some more exciting updates soon! Give it a try!

Well, well, well. Ruby on Rails strikes again!

[Carmine Paolino @paolino]

Couldn't be happier to see this. The Rails community has always prioritized programmer happiness and sustainable businesses.

Even in 2026.

Rails is very much alive.

From @josevalim's first commit to millions of lightweight processes running in production — happy anniversary @elixirlang! 💜

I love accelerating Rails development with agents. It's incredible how much progress you can make in such few tokens. https://t.co/ql3QEHz0PM

I got to ride a @zoox and of course had to blog about it😌

Matt's excellent Ruby AI newsletter is here.

If you've been living under a rock: Matt just finds everything regarding Ruby and AI and presents that with clarity.

Truly a gem of a newsletter.

・Shopifyが、Ruby向け静的解析エンジン「Rubydex GitHub
」を発表した。
・目的は、LSP・型チェッカ・ドキュメント生成・デッドコード検出などで重複していた“コード解析基盤”を統一すること。
・Rust製コア＋FFI＋Ruby gemという構成で、高速性と移植性を重視している。
・既��� Ruby LSP や Tapioca、Packwerk などへ導入が進み、性能や精度が大幅改善した。
・特にTapiocaでは、RBI生成時間が���6分から約20秒まで短縮されたという。
・MCPサーバも実験的に搭載され、LLMがコードベースを効率よく探索できるようにする構想もある。
・将来的には共有DB、セマンティックLint、型推論対応なども視野に入れている。

面白いのは、この記事が単なる「新ツール紹介」ではなく、“Rubyコミュニティのインフラ再編”として書かれている点です。Prism parserの成功体験を踏まえ、「解析エンジンも共有資産にしよう」という思想がかなり明確に打ち出されています。これまで各ツールが別々に苦労して実装していた定数解決や継承解析を、一つの基盤へ集約しようとしているわけです。

さらに興味深いのは、LLM時代をかなり強く意識しているところです。MCPサーバを組み込み、「grepして全部読む」のではなく、構造化されたコード知識へ直接アクセスさせる方向へ進んでいます。これは単なるIDE支援ではなく、“コードベースを理解するための共通知識層”を作ろうとしているようにも見えます。Ruby版のLanguage Infrastructure Platformを作ろうとしている、そんな雰囲気があります。
