Herb is a modern developer toolchain for HTML+ERB templates. Its goal is to bring more reliable parsing, smarter editor assistance, and better surrounding tooling to ERB templates. It emphasizes being “HTML-aware,” meaning it understands the real-world structure of templates where HTML and Ruby code inside ERB are interleaved. This makes it well suited to long-standing pain points in Ruby/Rails projects around template editing, diagnostics, and formatting.
Based on the captured content, Herb’s core is an error-tolerant, whitespace-aware parsing system with precise location tracking. It is built on Prism, the official default parser starting with Ruby 3.4, and is adopted by Ruby runtimes such as CRuby, JRuby, and TruffleRuby. Herb is also fast enough to support updates on every keystroke, suggesting a strong focus on real-time editor experiences. At the toolchain level, it covers modules such as a Language Server, Formatter, Linter, CLI, Dev Server, Highlighter, Syntax Tree Printer, Minifier, and Config Rewriter.
Herb primarily serves the HTML+ERB and Ruby ecosystem, but it is not limited to Ruby usage. The page lists native bindings for Ruby, Node.js, JavaScript/TypeScript, Java, and Rust, along with documentation entries for a C Library and WebAssembly, making it easier for tool authors to embed. On the editor side, it supports VS Code, Cursor, Helix, Neovim, RubyMine, Sublime Text, Vim, and Zed, and is LSP-ready, giving it fairly broad ecosystem coverage.
The captured text does not provide pricing, paid plans, enterprise support, payment methods, or any SaaS service details. It also does not clearly mention self-hosting options. The page provides a GitHub entry point and contributor information, but does not directly state the license in the main text, so its open-source license cannot be determined from the captured text alone.
Herb’s strengths are its clear positioning and dedicated focus on HTML+ERB. By building on Prism, it stays aligned with the future parsing foundation of Ruby. Its error tolerance, character-level location tracking, and high-speed parsing make it highly suitable for language servers, formatters, and diagnostic tools. Its limitations are that the current focus remains ERB, while support for more template languages is described as a future plan; the version is shown as v0.9, so it may still be evolving quickly; and commercial support information is limited. It is a good fit for Rails/ERB project teams, editor plugin authors, and developers who need to build static analysis tools for ERB.
No information was found in the text about access from mainland China, mirrors, payments, or compliance, so this is currently unknown. If access to GitHub or related package sources is unstable, Ruby LSP, erb_lint, htmlbeautifier, RubyMine’s built-in template capabilities, or Prettier ERB-related plugins may be considered as alternatives or complements.
