Hi HN,I built Small Transfers, a payments platform for SaaS &#x2F; API makers who want to bill customers per request instead of pushing them into subscriptions or pre-buy packages.*Why?*<pre><code> - Many customers hate subscriptions and&#x2F;or want to use a service occasionally.
 - Traditional payment processors add a fixed fee to every charge, making charges below 1 USD impractical.
 - Stripe UBB tracks usage, but you still need to write your own auth, add spending limits, and each merchant charges cards separately (extra fees for customers).
</code></pre>
*How it works?*<pre><code> - Each merchant has a Small Transfers account linked to their Stripe account via Stripe Connect, which is used to transfer payouts to merchants.
 - Each customer has a Small Transfers account where we verify them using Google Sign-In, 3-D Secure, and Stripe Radar to minimise the chances of a customer not paying their balance.
 - Customers allow your service to identify and charge them via platform&#x27;s own OAuth. This also removes the need for your service to implement its own auth. (Simple services don&#x27;t even need their own database.)
 - Merchants call a simple REST API to authorize and capture a charge with a minimum amount of 0.000001 USD. Note that you can authorize more than you capture, allowing you to authorize the max amount your request might use, and then capture your actual cost plus margin (great for many use cases, e.g., AI).
 - The platform takes care of charging customers and sending payouts to merchants.
 - Merchants pay a flat 3% fee. Customers pay payment processing fees when they pay for their balance.

 - Any concerns and how I could mitigate them.
 - Any other feedback.

Hey everyone,I built Indiebooks.io . A free bookkeeping app that automatically organizes your finances and fills out CRA&#x2F;IRS tax forms for you. It’s built for freelancers, indie devs, and small business owners in Canada and the US who want to stay compliant without spending weekends in spreadsheets.What it does
- Tracks income &amp; expenses automatically
- Handles GST&#x2F;HST, PST, QST (yes, even Quebec math)
- Supports US taxes and state sales tax
- Auto-fills CRA&#x2F;IRS tax forms so you can just review and file
- Lets you ask AI things like “What’s my profit this quarter?”
- 100% free — no limits, no credit card (might have to limit actual receipts image uploads if storage becomes too expansive)Why I made it:Bookkeeping tools are either too expensive or too complicated, especially for small businesses. I wanted something that just works, stays compliant, and doesn’t make you learn accounting to use it.Tech bits
- Built with NextJS, AWS, a bit of supabase, and a bunch of automations for tax logic
- Handles messy edge cases like multi-province taxes and mixed personal&#x2F;business expenses
- AI is constrained to actual numbers in your books (no hallucinated profit lol)Would love feedback on:
- Anything confusing or missing in the UI
- Tax edge cases you think it should handle
- Ideas for integrations (bank connections, Stripe, etc.)
- What would make you actually switch to it?It’s still early, but you can try it here: <a href="https:&#x2F;&#x2F;indiebooks.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;indiebooks.io&#x2F;</a>Would love to hear what you think, especially if you’re running a small business in Canada or the US.Thanks!-Max

Big news! I’ve just deployed the official documentation site for NextMin <a href="https:&#x2F;&#x2F;nextmin.gscodes.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;nextmin.gscodes.dev&#x2F;</a>This site is built to make exploring NextMin smooth, clean, and developer-friendly. Some highlights you’ll find inside:
 Dynamic Schema System – instantly create CRUD APIs from JSON schemas.
 Admin Panel – React + Tailwind powered, with live schema updates.
 API Router – flexible routing with JWT + API key authentication support.
 File Storage – seamless S3-compatible upload integration.
 Hot Reloading – backend &amp; frontend both update without restarting servers.
 Monorepo Ready – plug-and-play into any project with private npm packages.I built this because I believe dev tools should be fast, transparent, and adaptable – not locked behind walls. The docs site shows how all the moving pieces come together.Check it out here: <a href="https:&#x2F;&#x2F;nextmin.gscodes.dev&#x2F;" rel="nofollow">https:&#x2F;&#x2F;nextmin.gscodes.dev&#x2F;</a>Would love to hear your thoughts and feedback!#NextJS #React #NodeJS #TypeScript #OpenSource #DevTools #Documentation #NextMin

I started this boilerplate in July 2020 and I’ve been maintaining it for 5 years. It began on Next.js 9 and kept upgrading to Next.js 15+ (App Router), while upgrading the stack over time (Tailwind 1 → 4, ESLint 8, swapping Cypress → Playwright, etc.). The goal is simple: I kept rebuilding the same setup, so I packaged it and kept it updated.What you get (preconfigured, keep only what you need):- Next.js 15 (App Router) + TypeScript + Tailwind 4- Auth with Clerk (magic links, MFA, social, passkeys)- I18n via next-intl- DB with Drizzle ORM (PGlite locally)- Forms with React Hook Form + Zod validation- Testing: Vitest (unit), Playwright (integration&#x2F;E2E)- CI with GitHub Actions; Storybook for UI work- SEO (Open Graph, JSON-LD, sitemap, robots)- Observability: Sentry, logging with LogTape, log management &amp; uptime&#x2F;monitoring- Security: Arcjet (bot detection, rate limiting, shield rules)- DX details: ESLint&#x2F;Prettier, Lefthook + lint-staged, Commitlint, absolute imports, bundle analyzer- AI code reviewIt’s free and open source (MIT). Today the project sits around 11.8k GitHub stars and 2.2k forks. I’m still actively maintaining it and adding features.Repo: <a href="https:&#x2F;&#x2F;github.com&#x2F;ixartz&#x2F;Next-js-Boilerplate" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;ixartz&#x2F;Next-js-Boilerplate</a>Why I built itSpinning up auth, a DB, i18n, tests, and lint&#x2F;format&#x2F;CI for each new app was repetitive. This gives me (and hopefully you) a production-ready base in minutes, with opinionated defaults you can start.I’m open to suggestions and feedback, what would you like to see next? I’ll hang around in the comments to answer questions.

Hi HN,I had some time between jobs and used it to scratch my own itch: building the simple, non-cluttered finance calculators I was always looking for but couldn&#x27;t find without heavy tracking or confusing UIs.I focused on privacy and simplicity from the start. The tools are free and collect zero data.What I built:A precise German Payroll Deduction Calculator (for planning job changes&#x2F;salary negotiations).Maybe i want to add a tool for personal budgeting &amp; investing.Current Tech Stack: Ive started for the tax app with python backend and the frontend in nextjs. The second app for investing im builing in sveltekit rn which I like alot more. SVGs are self-drawn pathsI&#x27;m sharing this to get feedback on the tools themselves. If you have any suggestions for the UI&#x2F;UX, or other simple finance problems worth solving, let me know! Thanks alot!

Hi HN,
I run an affiliate site with hundreds of outbound links. Over time, these links break — products go out of stock, vendors change URLs, and sometimes media just disappears. I got tired of manually checking them, so I built check-my-links.com ...my first NextJS project.It scans my site regularly and flags broken links, missing images, or redirects — so I can fix them before users (or SEO bots) notice.It started as a tool for myself, but I figured others might find it useful too. Happy to answer questions or get feedback!Why did I not use existing tools?
- Google Search Console updates slowly
- Sophisticated tools cost hundreds per month
- Free tools are unreliable

I started my JavaScript journey with React and NextJS. But the more I worked with them, the deeper I questioned myself. Because even though React and NextJS are as powerful as hell, most of my needs in my web app development are just Database CRUD + Auth + Markdown Display. (It&#x27;s my problem, not React&#x27;s, I know...) And I found myself spending more time tinkering with the toolings and configs of the framework rather than coding the actual design and logic.There I started my search for the minimum JavaScript framework on which I can focus on what actually matters. I loved Svelte for two months, and then I found Alpine (from a blog talking about the &quot;AHA stack&quot;)!Though Alpine itself is not a complete solution as a JS framework, I love its simplicity and paired it with Astro, which can solve the component issue Alpine has.But mature frameworks like React and Vue have an unbeatable advantage over my minimum Astro-Alpine stack -- they have prebuilt component libraries like Shadcn, Radix, or NuxtUI.So I built Basis UI, a Shadcn-like UI library for minimum SSG frameworks like Astro (I&#x27;m also considering extending it to 11ty and Nue.js). So we can enjoy the dev experience like stacking LEGO blocks purely in Astro without choosing React&#x2F;Vue&#x2F;Svelte.It&#x27;s still in beta, so have fun playing with it, but don&#x27;t use it for anything serious :P

I&#x27;ve been working on a RAG-based solution that functions similarly to Context7 but at a significantly lower cost. After some rigorous testing, I thought I&#x27;d share my findings with the community.TL;DR: This implementation costs roughly half as much as Context7 while producing code of comparable quality.The TestsI ran three coding challenges using Gemini-2.5-pro (set to temp=0) with both Context7 and Custom MCP:- Creating a Next.js page with API data fetching- Building a FastAPI endpoint for streaming large files- Developing a FastAPI WebSockets app with Redis pub&#x2F;subThe Results- Average cost savings: ~40%- Next.js Test: Context7 ($0.056) vs Custom MCP ($0.023)- FastAPI Streaming Test: Context7 ($0.044) vs Custom MCP ($0.031)- WebSockets&#x2F;Redis Test: Context7 ($0.052) vs Custom MCP ($0.040)Both tools generated fully functional code that implemented all requirements, but the Custom MCP server did it at consistently lower costs.Why This MattersIf you&#x27;re building AI-powered coding tools or using them extensively in your workflow, these cost savings add up fast.For teams making thousands of API calls daily, you could be saving hundreds or thousands of dollars monthly.What&#x27;s NextI encourage you to try the MCP server yourself and share your feedback. Currently it supports the latest versions of Expo, FastAPI, and NextJS:{

I made this web app to replace the &quot;who brings what&quot; and &quot;who does what&quot; lists on google docs for our upcoming kindergarten fest.The stack is react, drizzle, nextjs and postgres. I&#x27;m working on letting OpenAI generate initial content for the pledge board, based on title and description. One topic I want to explore is subtle AI integration that doesn&#x27;t annoy users, like placeholder content in the input fields that fit the theme of the board. There are lots tweaks I have in mind for the future, like locking input fields when a user is entering their name, or encrypting the content with a passphrase.The landing page is still AI generated, which has a lot of fluff. I want to trim it down and give it some soul.Any feedback is welcome! Is this useful at all, or is google docs good enough?

Hey! I&#x27;m Chris. I got tired of opening multiple tabs to chat with different LLMs, so I built YamChat to solve that. You can talk to multiple LLMs from one place.One of the standout features, and the main reason I built YamChat, is you can ask a question to multiple LLMs in parallel. For technical questions I rarely trust just one LLM. I was getting tired of opening multiple tabs to ask the same question to various models, so I consolidated all of that into one location - YamChat.I also didn’t like paying for multiple LLMs. I wanted to be able to pay one price that gave me access to everything, which YamChat also provides.I&#x27;ve built it using NextJs and Convex, with WorkOs for auth and Polar for payments. It&#x27;s still pretty bare bones so I would love pressure testing! The free tier is admittedly pretty small, so if you run out of credits and want to give it a solid go shoot me an email, I&#x27;d be happy to make you a discount code for a free month.Let me know what you think!

# 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.
