Hyperclay just got better. Went from allowing a very limited number of malleable HTML files per user (10-20) to allowing unlimited files, all by switching to username-namespaced file paths. Everything's more intuitive and Hyperclay Local syncing feels so much better! Solves ∞ UX problems

Finished Hyperclay's invitation page today. Beta invites go out next week. 4 years of work preparing for this moment.

I generate single-file apps every day with LLMs. But: - Where should these files live? - What should i use to make them? I wrote about where I think lightweight software is heading. Not the AI part — the infrastructure. plumbing-of-everyday-magic.hyperclay.com

Someone should freeze a copy of the internet right now and pass it down to future generations as one of the few digital ecosystems not completely overrun by AI

Shipped a big Hyperclay Local update! 🌹 It's like Dropbox for local malleable HTML files. • It's just a tray popover now • Quick sync status • Recent uploads/downloads • Tightened up the sync engine Desktop app feels way more focused now.

my 18mo 👶 is vibe coding now

Chrome DevTools has a built-in filesystem proxy: you can locally override any HTML/JS/CSS on any site. Incredibly powerful. 🦸 But I just got burned. 🙈 Once enabled, it silently shadows any local file you open in Chrome without asking.

"Every generation mistakes its current map for the territory." — ChatGPT I love having deep philosophical conversations with an LLM at 6 AM in the morning. Truly fun.

Remote state should feel like local state. Mjölnir.js: what if db.users.find(str) was just frontend JS, whether you’re hacking locally or running search across a distributed fleet? Time for browsers to let web citizens make the web.

Just did my product video with remotion! 🎥 My process: have Claude generate each scene as a single HTML file or static image, iterate with Claude until it's A+, then ask to convert it to React/Remotion.

why does everything trump promises end up doing the opposite of what he says? he's making our streets LESS safe

15 years coding only to be replaced by a clanker called Ralph Wiggum...

anyone else looking at all these banger vibe coded projects on twitter and getting discouraged about their business? like: why am i building this big platform when someone could produce the same thing, custom to their use case, in a vibe session?

Claude Opus 4.5 is now the default in Claude Code. Here’s my take on the best coding model right now, and what I think is actually happening behind the scenes at Anthropic. 1/10 🧵 👇

Claude global config settings in ~/.claude/settings.json to make Claude turn off marketing messages into your Git commits:

I feel so lucky to be living in the age of AI. I just produced a script in 10 min that helps me automatically release NPM packages, using a local Claude Code to write the changelog entries. Mind blown 🤯

Want a fully custom date picker and the native calendar popup? Build your own UI, then call input.showPicker() to summon the browser’s date picker on demand.

I love my app's 471-bite blog template

I love my app's personal admin dashboard <3

plan with Opus, execute with Sonnet, code review with Codex 👌

Long time dream achieved: ✅ Become an Apple/MacOS Developer

The magic of React isn't worth it! There's a simpler model of the web that can fit into your head and doesn't require a non-intuitive, over-engineered framework. Not sure what it is yet... but it's coming. Read more: "React vs Backbone in 2025" backbonenotbad.hyperclay.com/

You can import shadcn or spend 56 hours designing the perfect tab component, or you can simply accept that this minimal tab layout is superior and ship it in 6 min.

Something I wish to impart to my children (now 4y and 1y): life in its raw form is unprocessable, so all humans have metaphors they process the world through. 1/5

Your move Mickey Mouse

Email is universal. Of course I want to email people who don't have the same domain name as me! This is the stupidest warning in Google Workspace — it should be OFF by default (if you want to turn it off: Admin console > Apps > Google Workspace > Gmail > End User Access)

Turns out when you decide to personally respond to all 105 people who responded to your welcome email with a custom-build HTML email (that includes an ASCII maze), you run into limits you've never run into before.

They could never have done it in Slack

ANTHROPOLOGISTS: It's clear now we should have started counting the years backwards after reaching the year 2000

When I posted OverType.dev to HN yesterday, I was thrilled to hit top 10. What I was NOT expecting...??! Getting to #1 on HN with Hyperclay.com today. Someone noticed the note in the footer on OverType and posted it!!! 42 early access signups so far 😲❤️

Launching OverType: → overtype.dev ← I got so frustrated with WYSIWYG editors I built my own. The twist? It's just a textarea. OverType: A transparent <textarea> layered over rendered markdown. You type plain text, but see rich formatting. 🧵 1/9

feel great being at the top of a session with Claude Code and about to get fresh tokens

I made a monospace revenue dashboard for my product, hyperclay. I will get out of the $0/mo club soon, mom! #buildinpublic

In years — not decades — there will be a premium on thoughts AI has never touched

Took me 2 weeks to plan out a major refactor. I organized the plans into sub-plans, until I had a 3-part refactor. Then, one night two weeks ago, I handed it all over to Claude Code at 4am. The result was truly beautiful 🤩 But... I've spent the last two weeks fixing bugs 😂

Early GPT-5 benchmarks feel more like a 4.x fine-tuning than a breakthrough. Solid gains, buy not the seismic shift we were looking for. The progress is a straight line, but the hype curve is exponential. Warranted?
