I'm not looking to be convinced about this tool as much as I am genuinely looking for a way to eval these kinds of tools in general
I have only just begun playing around with evals for a harness I'm working on and so far I have just been doing runs of converting https://github.com/realworld-apps/realworld from one language to another
not super pleased with it
the unsatisfying answer I think is that crafting good eval environments for long runs takes a lot of time, and there are many things you'd want to verify that you cannot simply lint or test for

From the project README
An excerpt from the repository, fetched Nov 13, 2026.
Read the project’s introduction
See how the exact same Medium.com clone is built using different frontends and backends
You can combine any frontend with any backend, because they all adhere to the same API spec
While most "todo" demos provide an excellent cursory glance at a framework's capabilities, they typically don't convey the knowledge required to actually build real applications with it — nor the real-world constraints a minimal demo never has to face.
RealWorld solves this problem by providing the same demo app for each framework, at a sweet spot between simplicity and breadth.

Implementations
Over 100 implementations have been created using various languages, libraries, and frameworks.
Explore them on CodebaseShow.
Spec-compliant backends
These backends pass the full API spec test suite:
Nitro + Prisma + Zod — TypeScript
Django Ninja — Python

Documentation introduction
Every tutorial is built against the same API spec to ensure modularity of every frontend & backend
A shared CSS theme is provided to build frontend implementations with identical UI/UX
A shared E2E test suite is available to validate frontend implementations
There is a hosted version of the backend API available for public usage at api.realworld.show, no API keys required — demo accounts are provided, and real accounts can't see each other
There is an angular frontend plugged to this backend available at demo.realworld.show

72 sourcesCompletely agree! I did most of this work and I wanted to add before-and-after benchmarking but I got busy. I have an in-progress (private for now) implementation of the Medium clone RealWorld [1] project. I want to make that public with some benchmarks, then write up a modern implementation in Rails so we can compare performance. It will also help people compare our code side-by-side, to translate concepts they know from Rails into our approach in Hanami.
[1]: https://github.com/realworld-apps/realworld
In Hanami 3.0: In Full BloomI'm currently running autoresearch against my harness that autonomously builds SaaS against an enforced architecture, and autoresearch managed to improve the harness performance on my 'time-to-Realworld' benchmark which has Claude Code drive the harness to build an implementation of https://github.com/realworld-apps/realworld with the win condition that it must pass my rigorous postman collection + playwright test suites. Experiments are capped at 90 minutes and the metric it optimises for is calculated from a weighting against number of tests passing, alignment with harness engineering best practices, and time to completion.

2 points · Open discussionI enjoyed slightly more fine grained comparisons, like: https://youmightnotneedjquery.com/ (this hasn't been updated in a little bit, it seems)
Either way, I think you're right, just use whatever works for you.
I'd admittedly love to see a larger scale comparison of going vanilla JS vs recreating the same functionality in jQuery/Vue/Angular/React, for a real world apps and what the takeaways are from that, say, 50'000 SLoC instead of 100, that'd probably be more useful, but also is way more unlikely. Nobody will put in that much effort just for the sake of a comparison and so a lot will be up to opinion and comparing vaguely similar projects.
Closest I've seen was https://medium.com/dailyjs/a-realworld-comparison-of-front-e... but still a fairly simplistic example, given the large amount of options that were compared. Still very cool, les

It's just for web app (a Todo app). Your GIS and CLI ideas are interesting, I haven't seen anything similar to realworld for those.
In Ask HN: Reference applications to idiomatically learn languages/frameworks?So what would be a better benchmark? Perhaps a "standard" "real world" app, like https://github.com/gothinkster/realworld
> The RealWorld Demo is a large community-backed open source project that showcases all web frameworks client or server-side through a building an example app that is much more substantial than the typical TodoMVC toy demos or the stripped out scenarios you find in benchmarks. As Conduit, a Medium clone of sorts, your application has to handle real issues like authentication, routing, and async data loading. It has a standardized specification [...]
Or something simpler?
In Rage: Fast web framework compatible with RailsRealworld: “The mother of all demo apps” – Exemplary fullstack Medium.com clone
2 points · Open discussionFor a similar project, someone put together a spec for a basic clone of Medium split into a frontend design and backend API, and now has over 100 different components where you can pair any frontend with any backend (plus a few fullstack implementations).

Not as performance-focused with benchmarks, but a good point of comparison for various languages and frameworks implementing common behavior.
In Programming language comparison by reimplementing the same transit data appYW, sure please check this: https://github.com/gothinkster/realworld
It's a collection of 100 implementation of the same project but in different languages. This might help you to choose your preferred stack and see a real world example on how to use them and learn
In Can I build my SaaS in no-code toolsThis is the approach I've settled on too.
I'm almost finished my first backend implementation of https://github.com/gothinkster/realworld and now that I've implemented it once I'm very familiar with it and could very quickly implement it again.
It's simple enough to be a short project, but with enough complexity to get you familiar with a wide variety of things you might care to know. One thing I like about it is you can kind of under or over engineer it as much as you want as a way to turn the dial either up or down on exactly how many different aspects of development in a certain language/framework it exposes you to.
In Ask HN: What do you code when learning a new language/framework?Looks like you're basically looking for TodoMVC and Real World. TodoMVC is a simple todo list implemented in various frameworks while Real World is a more complex real world app, a blog style social media site.
