NextJS but in Rust

Hi HN,Creator here of x402-hosting. The idea is that vibe-coded projects need hosting too! Some friends of mine asked how to convert a .tsx file into a link, and that got me thinking. Wouldn’t it be great if you could just ask the agent itself to deploy the project for x amount of months and return a live URL...Maybe agents will start using this, maybe not. At least it was a great excuse to play around with the x402 payment-required protocol.

Hi HN, I&#x27;m a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs.Now I&#x27;m joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a dark age when I was studying after the Fukushima event) so I think this is the right moment for me to jump again into the field.Reactor atlas is an interactive nuclear reactor map and an intelligence layer on top of it. The basic layer indexes:<pre><code> - power reactors
 - research reactors
 - fuel facilities
</code></pre>
with their history and projection, by country. The project is solving a fragmented information ecosystem, where operational and commercial data is hard to conciliate. Also, I&#x27;m monitoring nuclear news associated with each of the facilities, political declarations that may affect the nuclear landscape and geo-phisical news (like earthquakes) that could affect operation. On top of the operational + news layer, I&#x27;m creating an intelligence layer that will help institutions of different types make faster decisions by subscribing to very specific alerts.As an engineer, I used to code in fortran and c++ when I was working at CNEA, and later I participated in the first Rather Labs projects architecting complex async systems, mostly using MERN stack. I&#x27;m no longer coding anymore. I&#x27;m focused on designing robust systems with AI agents.I mainly used Claude Fable 5.1 to develop reactoratlas.com, deploying on vercel and using mostly nextjs, threejs, postgreSQL and some cron jobs to query and update data. I miss coding as in the old days, but I haven&#x27;t code a single line in this project. And I strongly believe we humans shouldn&#x27;t code anymore: our responsibility is now on designing and supervising AI systems.Thanks for your attention!

```This post mostly outlines how I am personally building with agents, as I am almost entirely hands-off.Desired feature-set determined by having agents research existing products and feedback &#x2F; feature requests on FIRE subreddits.Features built using Opus 5.5 (xhigh) &#x2F; Fable 5.1 (med&#x2F;high) as orchestrator and Opus-5-5 low&#x2F;medium as worker subagents.Quality is attempted by running Opus-5-5 agents in a perpetual audit + fixer loop on the calculation &#x2F; compliance engine until no medium+ severity can be found. The origin of each rule &#x2F; logic must be backed up and documented in the codebase with a source.Sonnet subagents run UX &#x2F; QA audit on iOS simulators within the Claude Code desktop app, and Opus agents resolve all medium+ sev issues; also run on a perpetual loop.I have not manually tested or used the app(s) for more than 30 minutes. For UX quality, agents&#x27; screenshots + associated context are fed to a combination of GPT &#x2F; Gemini &#x2F; Claude agents until consensus is achieved on quality (7&#x2F;10+).Early feedback from beta testers report extremely close results to Boldin &#x2F; Projection Lab. There is also a feature to import your data from Boldin and Projection Lab into CoastMath if you wish to compare the results yourself.There is also a SimpleFIN integration, if you wish to pull in your own transaction data and see how your financial future changes based on your monthly spending habits (e.g. when I will get to retire if I spend like I did in June vs. July?).I&#x27;m sure there are other features I don&#x27;t yet know about. Again, I&#x27;ve barely used the app.Anyway, feel free to use &#x2F; roast &#x2F; steal. I don&#x27;t think that any moat can exist in this class of products in the future (where the rules are laws that are visible to everyone) and I don&#x27;t expect to turn a profit.Estimated cost: maybe $2000 if done over the API? I did most of this using the $200 Max subscription.

I searched for one and was shocked how expensive they were. I mean they are just using apis right. I didnt want to pay $50&#x2F;month just to post on multiple accounts... Figured it couldnt be so hard and build one my self. I use a third party provider for posting but might switch to my own integration with the apis. Build with Next Js and Supabase.

Show HN: Made a social media scheduler that doesnt require a subscription

Hi HN,
I was frustrated with expiring credits, subscriptions and generally BS approach in image&amp;video generation space (which is now universally useful and basically a commodity) so I&#x27;ve built Azurade, a hosted service where you have 35+ models (Veo3.1, Seedance 2.5, Wan 3.0, Nano Banana, GPT Image2.5 etc.) behind one non-expiring, fully agent native balance.
I care about billing, that&#x27;s why credits are prepaid and never expire, a failed generation is refunded automatically, and you can buy a pack without a subscription. I got tired of monthly credits (or usage) that vanish at the end of the monthThis post is mainly about it&#x27;s remote MCP server, because that&#x27;s how I and my friends mostly use it now (via Claude or Codex)You can add <a href="https:&#x2F;&#x2F;azurade.com&#x2F;mcp" rel="nofollow">https:&#x2F;&#x2F;azurade.com&#x2F;mcp</a> in Claude or Codex (or claude code), sign in once through OAuth and the LLM will be able to generate &#x2F; get all info about models and account &#x2F; upload files and all that.I&#x27;ve ran it through oblivious evaluator agent for 8 times to reach good agent ergonomics. After all, if I want to build an agent-native service the users (agent) should evaluate and correct it.
Please feel free to point your agents at it and send me the nitpicks and gotchas they encounter. Humans are also welcome :)Demo video (1m40s, cute dog included): <a href="https:&#x2F;&#x2F;youtu.be&#x2F;tX29WLffXCk" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;tX29WLffXCk</a>P.S. the stack is Go and Pocketbase, official GO MCP SDK, and the frontend is statically rendered NextJS. The access token is an API key named after the client, so revoking an agent means deleting that key on your profile page. It also works like REST API with an OpenAPI spec.

Hi HN, I&#x27;m Andrei. I built a money tracker for myself with everything I ever wanted from one.What was important for me is wallets in different currencies (I travel a lot), planning future payments, seeing what balances would look like at certain date in the future and having external API and MCP.I had plans of maybe making it public one day so I decided to encrypt amounts and balances to stand out from gazillion of other trackers, then I kept adding more stuff like semantic search, charts, shared wallets for collaboration, passkey-only sign in and so on.It&#x27;s a web app, I use it as PWA and it works fine for now. Native mobile apps are worth making only if there is demand, so current stack is Nextjs, Hono, Postgres, a VPS and Cloudflare.I&#x27;d love feedback, especially on encryption and collaboration part and what would make you switch from your current tracker.

Things incoming when this goes live- “I made doom run with only css functions!”- “CSS function vulnerability exposes api keys in NextJs server side rendering”- “css function used for fingerprinting violates EU laws”- “Facebook&#x2F;Meta caught tracking users using CSS function exploit”I’m being facetious, mostly.

The Future of CSS

Unless scale or resources are a concern, I see absolutely no reason to use anything else for CRUD apps. I sure as hell won&#x27;t be writing any `sql` statements in nextjs anytime soon.

Does Ruby on Rails still make sense?

Just the ReactFiberWorkLoop.js has 5k+ lines of code. React is one or two orders of magnitude bigger than you are thinking. And that&#x27;s not counting Nextjs.

Using Claude to reduce the attack surface of code

Well, it&#x27;s either typed and memory managed Rust or underperforming NextJS&#x2F;Python slop. Also, I&#x27;ve read way more Rust and understand it more than I ever did before AI tools became good enough. Using a neat package called Crux for cross platform apps which uses the Elm architecture, which I&#x27;ve very familiar with and have written in the past. Instead of gatekeeping, try opening the door and finding out how to help - it&#x27;s Rust&#x27;s time to shine.

React is actually pretty good for any kind of reactive interface, and it&#x27;s small. Something under 3k lines of code, and it&#x27;s well battle tested at this point.You might have a dislike of react and that&#x27;s fine, but it&#x27;s not adding any significant attack surface to a project.Nextjs on the other hand...

The irony of a company using Nextjs for a chat app and React for a terminal UI talking about reducing attack surface.

Unless we&#x27;re talking about figma-like web apps, Content is usually a different department than development.I know it&#x27;s becoming more and more outdated nowadays, but if a magazine or a news website is still written by humans rather than AI they need a way to provide formatted text and media, and preview the output.On the other hand I should add that i&#x27;ve also seen an upward growth in CMSes like WordPress being used exclusively as Online Editors, with content ultimately being exported trough REST to completely different backends and frontends, like a Firebase&#x2F;NextJS infra.

Drupal is now light-years ahead of its reputation

Cloudflare is exclusively what I use for any infra work I do (and I do a lot for various projects and startups of my own&#x2F;others I advice). If something doesn’t fit cloudflare primitives, I try to rethink my design before reaching for gcloud etc.They even do docker containers now which is great but durable objects and workers are game changer for me.The easy nextjs deployment is also my go-to now that vercel isn’t my preferred vendor.

I run up against this every day. A problem with a verifiable answer on the other hand it&#x27;s very good at solving. He knows this (his next paragraph) but he&#x27;s putting them on the same scale of &quot;stressing the system&quot; to attempt to add proof to his introductory claimAnd then there&#x27;s the completely unverifiable scare that there are internal frontier models way beyond anything we&#x27;ve seen &quot;swarms of thousands of agents collaborating over weeks on software mega projects: minting zero days, running cyber attacks and defenses at machine speeds, discovering new science, advancing the frontier of mathematics&quot;I dunno.

# This is a NextJS
NextJS is a **framework for ReactJS**.

Wait a second ... a "framework" for React? Isn't React itself already a framework for JavaScript?

Well ... first of all, React is a "library" for JavaScript. That seems to be important for some people.

Not for me, but still, there is a valid point: React already is a framework / library for JavaScript. So it's already an extra layer on top of JS.

## Getting Started

Create Next App:

```bash
npx create-next-app
# or
yarn create next-app
```

First, run the development server:

```bash
npm run dev
# or
yarn dev
```

Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.

You can start editing the page by modifying `pages/index.js`. The page auto-updates as you edit the file.

[API routes](https://nextjs.org/docs/api-routes/introduction) can be accessed on [http://localhost:3000/api/hello](http://localhost:3000/api/hello). This endpoint can be edited in `pages/api/hello.js`.

The `pages/api` directory is mapped to `/api/*`. Files in this directory are treated as [API routes](https://nextjs.org/docs/api-routes/introduction) instead of React pages.

## Why would we then need NextJS?

Because NextJS makes building React apps easier - especially React apps that should have server-side rendering (though it does way more than just take care of that).

In this article, we'll dive into the core concepts and features NextJS has to offer:

- File-based Routing
- Built-in Page Pre-rendering
- Rich Data Fetching Capabilities
- Image Optimization
- Much More

## File-based Routing

## Learn More

To learn more about Next.js, take a look at the following resources:

- [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
- [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.

You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!

## Deploy on Vercel

The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.

Check out our [Next.js deployment documentation](https://nextjs.org/docs/deployment) for more details.
