What I learned building a SaaS alone for 3 months

I didn't have a co-founder. No team, no office, no standup meetings. Just me, a laptop, and a feature I couldn't get to work.

The feature was the whole point of the app.

You type /ai in a document, describe a tool you need, and a working interactive component appears inline. Not a code block. A real, running UI inside your note.

Simple to describe. Hard to build.


The part that broke me first

Getting AI-generated code to render safely inside a rich text editor is not straightforward.

The component had to be sandboxed so it couldn't touch the parent app, but still functional enough to do useful things. I got that wrong more times than I want to admit.

The iframe configuration, the CSP headers, the streaming approach, each one had an edge case I didn't see coming. I'd fix one thing and break another.

Some days the only visible progress was a slightly better understanding of why it didn't work.


The moment I knew it could ship

Then one day I typed a prompt, and the component started generating.

Not a broken render. Not a half-working preview. A real, interactive tool appearing inside the document as the AI wrote it.

That was the moment I thought: this is different.

Not because the code was perfect, but because the experience felt like something that didn't exist before. The tool and the thinking behind it, living in the same place.

After that, finishing felt possible.


What three months alone actually teaches you

You make every decision.

Tech stack, pricing, copy, color of a button. Nobody to delegate to, nobody to blame.

It's clarifying in a way I didn't expect. You stop overthinking and just ship, because the alternative is sitting still.

You also learn what the product actually is by building it. My initial idea shifted significantly. The core stayed, but the details changed constantly as I ran into real problems.

The hardest part wasn't the code. It was the stretches where nothing seemed to be moving.

Progress in software is invisible until suddenly it isn't.


Where it is now

Fluxerv is live. Free to start, no waitlist.

I'm launching it on Product Hunt on June 16, 2026, with 20% off Pro using code PH20OFF.

If you're building something alone and feel stuck, keep going. The gap between "this doesn't work" and "this is exactly what I imagined" is usually smaller than it looks.
