   Has almost everything I need

   I've started using this as my main IDE for new projects when I'm trying things out. If it keeps getting better at the rate it has been, it'll be even better than coding locally.

   🏁 Competitors: replit

   👍 Pros:    Easy to get started and operate|Fast|Supports common extensions|Works with most npm packages

   👎 Cons:    Still not as good as local development|Can be hard to debug|Build times can be slower than local

• Ruby for Good

  Which can include type assertions but also a lot more. The agents seem to do well with this. I've also had good results using agents to write Crystal https://crystal-lang.org/ which is Ruby-like but does have the static types and produces blazing fast static binaries. Might be a sweet spot for coding agents if you're building some backend services. But I'd still pick Ruby on Rails for a new full stack project. - Source: Hacker News / about 1 month ago

• Ask HN: What Are You Working On? (May 2026)

  Sounds a lot like Crystal, which is also similar to Ruby and features a green fiber runtime: https://crystal-lang.org/#concurrency. - Source: Hacker News / about 2 months ago

• A Grand Vision for Rust

  > 1. Go with a better type system. A compiled language, that has sum types, no-nil, and generics. I was looking for something like that and eventually found Crystal (https://crystal-lang.org) as a closest match: LLVM compiled, strong static typing with explicit nulls and very good type inference, stackfull coroutines, channels etc. - Source: Hacker News / 4 months ago

• Response to Ruby Is Not a Serious Programming Language

  Wondering why https://crystal-lang.org/ hasn't been mentioned in the comments. - Source: Hacker News / 7 months ago

• Show HN: Ü Programming Language

  > What kind of code snippets could you suggest? Anything really! Some websites that do this currently: https://ziglang.org, https://crystal-lang.org and https://www.ruby-lang.org/en > I have a comparison table mentioning features Yes - I did see this in the README. Maybe worth adding it, or something similar to the website. - Source: Hacker News / 8 months ago

• RS-X: Framework-agnostic reactive state and expressions for JavaScript/TS

  Managing reactive state and dependent computations in JavaScript can get complex, especially when combining asynchronous and synchronous data. RS-X is a library that allows you to bind expressions to plain objects and makes the parts of the model used by those expressions fully reactive. Dependent computations automatically update when the underlying data changes. RS-X is framework-agnostic. While it can drive UI... - Source: Hacker News / 5 months ago

• Show HN: I combine Htmx, LiveView and SolidJS for interactive server components

  I like htmx, LiveView, React and Solid. They are great at different points, so I try to combine them in Solv (Stateless Offline-capable LiveView) and write a prototype to show the benefits. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is... - Source: Hacker News / 8 months ago

• Show HN: Solv – Stateless Offline-Capable LiveView – Prototype 03

  I like htmx, LiveView, React and Solid. They are great at different points, and this is a prototype trying to combine them. Solv's main idea is that stateless servers keep client's state in a volatile cache. It enables server components that are also interactive, which is best of both worlds between LiveView and htmx. Then fine-grained reactivity is added to achieve efficient DOM updates + minimal payload size.... - Source: Hacker News / 8 months ago

• AutoView - turning your blueprint into UI components (AI Code Generator)

  In the code editor tab (powered by StackBlitz), navigate to the env.ts file and enter your OpenAI key. Run npm run generate in the terminal to see how @autoview generates TypeScript frontend code from example schemas derived from both TypeScript types and OpenAPI documents. - Source: dev.to / about 1 year ago
