Updated the landing page headline based on your feedback. Thanks!

Haha. But I am seriously thinking about MCP. It's one of the candidates for the next feature, but I'm hesitant because it could be used to mass-publish low-value posts (think E-E-A-T). Have you ever needed MCP for running your blog?

Someone asked how it holds up with a long post and large images, so I made a sample: https://bloffy.bloffy.blog/en/a-heavy-post-long-text-and-lar...

And here's the PageSpeed Insights result: https://pagespeed.web.dev/analysis/https-bloffy-bloffy-blog-...

It's a long post with lots of images in different sizes, plus diagrams and math.

Images uploaded in the editor get a srcset with 4 widths, and the CDN compresses them to suit each browser. Since we know each image's original width and height, the layout doesn't shift.

Diagrams and math are rendered to SVG and MathML when you publish, so readers can load them quite fast.

I actually wanted to talk about this too, so I'm glad I got the chance to answer. Thanks.

(The SEO score there is low only because the sample blog is noindexed.)

Thanks, you're right. It's just lab data for now. I'll check it again once we get real visitors.

Oh, I see. I didn't know about the showdead setting. Thanks for letting me know!

Thanks! I'm a solo developer based in Korea. Since it's not a company, I'm not sure what I should put there. What do solo developers usually include on their About page?

Oops, you're right. The CSS was showing up as-is in the summary of the first post on the list page. I've edited the post. Thanks!

Thank you so much. This is my first time sharing my product on Hacker News, and every bit of attention like this makes me really happy.

1. You're right. I actually considered it, but I thought a demo would make the landing page quite heavy. Your comment gave me the idea of making a separate page where you can try a demo. Great suggestion, thank you.

2. Thanks. This was actually intentional. As a first target, I'd like Bloffy to appeal to developers who care a lot about SEO. Bloffy is also a bit different from typical blog products built to be easy for everyone. The goal is for it to grow, over time, into a blog customized to you. The first target is developers, but going further, SEO professionals who can handle HTML, CSS, and basic JS could be a target too.

3. You're right. I'll make the differences clearer on the landing page, and I'm also planning to write a separate post about how Bloffy differs from other blogging platforms.

4. I think you mean the demo video on the landing page? The pace does feel a bit fast. I was trying to keep it under a minute. I'll take that into account. Thanks!

Haha, right? Bloffy doesn't use PHP at all.

The confirmation email is no longer sent in Korean. It now comes in the language of the site you signed up from. Thanks for catching it!

Fixed.

There's currently a bug that breaks sign-up on every language version of the site except English. If you'd like to sign up now, please use the English sign-up page and keep the site in English until you're done: https://bloffy.co/en/workspace/sign-up

I'm fixing this right now.

Yes, it's a hosted service.

My native language is Korean, and by "your own blog" I meant something like "a blog that's truly yours." I was trying to sum up a few things in that one phrase: you can customize it freely, the platform interferes very little, it's friendly to raw HTML, and it allows JavaScript. I think that line could be misleading, so I'll need to reword it.

Thank you.

I see. Fair point, thanks. I'll try to improve it on mobile.

Thank you so much for the feedback.

The confirmation email being sent in Korean does look like a real bug. I had set English as the default, but it seems I missed this part. Thanks for pointing it out.

You're right that the word "Translation" can be misleading. For now, translations are meant to be done manually, but I'm also considering automatic translation in the future. Automatic translation can change the meaning you want to convey, so I'd still recommend translating posts yourself. But for convenience, I'm thinking about adding automatic translation.

Thanks again.

“React Native is not a dying technology.”

- There is a widespread misconception that “React Native has been discontinued” or that “Meta has abandoned it.” - This is not true. React Native continues to receive regular updates and is actively discussed at major global conferences. - The confusion largely stems from Meta’s new product Threads being built with fully native technologies (Swift and Kotlin/Jetpack Compose). - The rumor that “even Meta has abandoned React Native” is only half true — Threads chose native for product-specific reasons, while React Native remains actively used across many products.

- *Instagram* - Adopted React Native starting in 2016. - Achieved 80–99% code reuse, significantly improving development speed. - Delivered better UX than WebView-based approaches and reduced build times.

- *Facebook Marketplace* - Core UI surfaces (Seller Hub, product detail pages, profiles, etc.) were built with React Native. - Implemented complex gestures and animations using tools like PanResponder. - Meta engineer Blair Vanderhoof: “React Native was key to Marketplace’s growth.”

### Maximizing Productivity in Chrome Without a Mouse

- If you care about productivity, reducing mouse usage in Chrome makes a real difference. - Most frequently used features can be handled with a single keyboard shortcut. - Internalizing these shortcuts noticeably speeds up tab management, navigation, and development workflows.

### Essential Tab Management Shortcuts - Switch tabs: `Ctrl/Cmd + Tab`, `Ctrl/Cmd + 1–8`, `Ctrl/Cmd + 9` - Close / Reopen: `Ctrl/Cmd + W`, `Ctrl/Cmd + Shift + W` - New window / Incognito window: `Ctrl/Cmd + N`, `Ctrl/Cmd + Shift + N` - Search all tabs: `Ctrl/Cmd + Shift + A` → Especially useful when you have many tabs open - Open history: `Ctrl/Cmd + Y` → Perfect for “What was that page I just visited?” moments

### Basic but Essential - Back / Forward: `Ctrl/Cmd + [`, `Alt + ←` - Scroll: `Space` / `Shift + Space` - Focus address bar: `Ctrl/Cmd + L`

### Hidden Power of the Address Bar - Use it as a calculator (type expressions directly) - Perform instant unit conversions (e.g., cm → inch) - Type `@` to switch search modes (including AI mode) It’s not just a URL field — it’s closer to a quick command launcher.

### Developer Shortcuts - Open DevTools: `Ctrl/Cmd + Option/Alt + I` - Toggle element picker: `Ctrl/Cmd + Shift + C` - Hard refresh (ignore cache): `Ctrl/Cmd + Shift + R`

I ended up playing this for 3 hours. Really great job! cheer !

Yeah, I feel the same. Deploying Next.js outside of Vercel always comes with a few extra headaches. It’s great on Vercel, but not as smooth elsewhere.

Next.js comes with several built-in capabilities. For example, it supports prefetching, server-side caching, and even cache clustering if you need scalability.

It also has a significant market share right now.

Of course, React Router 7 (and Remix) can handle similar features. But adoption matters — a larger ecosystem usually means better job opportunities and stronger community support.

If you haven’t used any major framework yet, I’d recommend starting with Next.js. It’s a solid way to learn the modern React stack and understand how full-stack React apps are structured.

This is goood news for me. Finally! A safer and more predictable alternative to innerHTML.
