Hello world, I'm Coen. Mostly known for working at WooCommerce or my Mozart package. I've been building other people's projects for 20+ years.

I'm fully focussed on @lapisense now. Terrifying and exciting at the same time! Would love to connect to founders on similar paths.

@mattpocockuk At least it’s nice and shiney and colourful!

A tool asked $1600 to migrate 12 years of HelpScout data to Freescout. $400 just for last 3 months.

GPT 5.5 at medium effort nailed it in 5 minutes and less than 10 prompts.

What a time to be alive.

This post is now ~2 weeks old and I've actively been looking into getting more involved with like-minded people in my field of work. It's just silly how some seemingly small changes like this, make me a lot happier.

In a world of tech, it's still about people. The human aspect matters more than ever. This video by @theo unexpectedly hit hard for me today. I feel lonely. Not in the literal sense, but the developers part of my heart feels lonely. 🥺 https://t.co/NTsGIM7SAk

@dannyvankooten As if you did know what to cut, pull out or leave as is, when you started out writing code. 😉

The 2-4 hours you spend scrolling each day (or 730-1460 hours each year) is more than enough time to write a book, build a business, or get in shape. In the moment, it seems like nothing. That's why it's so dangerous. Your time disappears without you being conscious of it.

[dax @thdxr]

finally found the right metaphor for this shift in how i use opencode.

i used to treat it like 3D printing, where you build the thing layer by layer and commit to each piece as you go

now it feels more like progressive rendering, you start with a blurry version of the whole thing, then keep making full passes over it, and each pass sharpens the entire shape

doing this with gpt 5.5 and voice prompting is the first time things feel like they're clicking

I couldn't help but add our new MCP to another project I've been slowly working on (more on that later)

What you think will ruin your life usually doesn’t. What you think will complete your life never does.

[Coen Jacobs @CoenJacobs]

@chrisfromthelc @jeffr0 Yeah, that's what I've been assuming. But still, it makes your pizza delivery service look bad (they admitted something went wrong with the order, reason why it was so late - not, why it was cold, on the phone) and then still assumed I was trying to scam them?

[Coen Jacobs @CoenJacobs]

@KatieKeithBarn2 Not just more credible to AI's, it makes it more credible to everyone in general. It's tempting to 'quid pro quo' this, but what's the point of a roundup/comparison if it's not honest?

[Coen Jacobs @CoenJacobs]

@jeffr0 Probably to prevent me eating two pizzas for the price of one…

[Coen Jacobs @CoenJacobs]

Just had pizza delivered. 60 minutes late and worse, cold. Obviously, I called and complained. Then, when they delivered new ones, I was expected to return the old ones?! Am I really a prick for flat out refusing to do so (also after having thrown the cold ones out already)?

[Coen Jacobs @CoenJacobs]

This is why deterministic code still is very important and agents just add an intelligent layer on top of it, where needed. This is also why I’m a firm believer that Claude Code loops are a significant costs overkill for 99% of what they’re used for currently.

[Elvis @elvissun]

someone burned $6k in tokens with one /loop run.

event-driven > cron

[Coen Jacobs @CoenJacobs]

@elvissun Yeah, I get how you do it and that’s a great way. But the Reddit post you added clearly had their agent check for PRs every x minutes and keep doing that over and over and over again.

Mozart 1.2.3 is now available, a focused fix release resolving a couple minor annoyances resulting in a very much more stable release: https://t.co/WB89VqIi1W

[Carl Hancock 🚀🇨🇷 @carlhancock]

The WordPress community has a visibility-to-competence ratio problem. The loudest voices aren’t always building products of any real substance.

Posting frequency, podcast appearances, and conference stages don’t tell you how big the business actually is.

Some of the most visible people here run companies that aren’t nearly as successful as their personal brand suggests.

Building a real product, not a feature with a landing page, is harder and slower than building an audience. Post count is not a proxy for competence.

Worth keeping in mind when you’re deciding who to learn from.
