I built my [own blog platform](https://docs.bloggo.blog/posts/what-is-bloggo/) using agents over a weekend. I’ve now moved [here](https://ronie.bloggo.blog/posts/you-need-more-tools/), and Medium no longer makes sense for me. But other SaaS matter even more than before.

Medium has always been really good. Great SEO (I got my current job at Shopify because they found a post of mine there), nice to read, simple and straightforward to write on. How could I not love that?

On the other hand, a couple of things bothered me: pop-ups, a weird ad in the middle of my post, and no way to get rid of them (it seemed that even paying wouldn’t help, though the docs I found were unclear).

And the worst part for me: no API to manage my posts, plus barriers against bots and agents. That’s actually a feature for most people. Unfortunately, not for me.

I tried other options. None were even okay.

Then, last Saturday (today is Monday), I finally said: let’s do it. And I built a blog platform exactly the way I wanted. In a couple of hours. From my phone.

And it’s freaking AWESOME!

For the curious, the whole stack was two things: Claude Code’s new “Project” feature, where agents wrote all the code while I chatted with them from my phone, and Cloudflare, where everything runs. That was all it took.

## What makes a SaaS resistant to “Build Your Own Software”?

Saying that every SaaS is going to die because of AI coding isn’t exactly the most useful simplification.

Shopify itself is a good example of one that’s getting stronger and stronger with AI. Stripe is another. Cloudflare is riding the wave. YouTube has never been stronger. But several others are starting to feel the impact.

If you work at a SaaS company, the best question to ask is, “Why would people stay here?”

My take is: **maybe not because of your core business**.

It’s easy to create a blog or an online shop. Not so easy to integrate with other services. Even harder to have the right infrastructure. Harder still to handle all the nitty-gritty details of “secondary” concerns: taxes and legislation, fraud and abuse, resilience, scaling, and so on.

Those are the hard problems. They demand constant attention and are very hard to tackle alone.

For my personal blog platform, those aren’t a problem. No payments, just me and a few friends I know publishing, and no physical goods going anywhere.

For anyone making a living from a SaaS — content creators and entrepreneurs — those cannot be afterthoughts. A half-baked solution means lost money, far more than the savings from “avoiding a SaaS.”

## Very good. So what?

First, build. **Build like crazy.**

Build tools, build the software of your dreams, build the next big SaaS, build the perfect niche software that only you and three other people in the world would love.

Second, **know what “Build Your Own Software” can’t replace.**

And thank you, Medium. No sarcasm. I really enjoyed my time writing there.
