What does The Free Battery Factory build?

We build modular developer tools shipped as batterypack packages. agents/BP for memory and orchestration. More on the line.

What is a batterypack?

A batterypack is a self-contained, composable module designed to snap into your stack. Each pack handles one concern well — so you install only what you need.

The core packages are free and open. Install what you need, nothing you don't.

We Make the Batteries.

Modular power for autonomous systems. Install what you need, nothing you don’t.

Batteries are the boring-but-essential parts everyone forgets to include. We make them. Then we write about why they work.

What We Ship

Tools, consulting, and open-source modules.

Cognitive Ergonomics Audit

We measure the invisible tax your interface charges every user, every session. Three friction points minimum, usually more. Then we eliminate them.

Infrastructure Hardening

CI/CD, containerization, monitoring, DR drills. The unsexy work that keeps your 3 AM self from getting paged.

Open-Source Modules

Self-contained packages that handle one concern well. Compose them however you want. We don’t bundle things you didn’t ask for.

How We Work

Fractional CTO. Architecture audits. Cognitive ergonomics.

Fractional CTO engagements, architecture audits, and cognitive ergonomics consulting. We design systems around how brains actually work.

Frequently Asked Questions

Quick answers. No fluff.

Why ‘Free Battery Factory’?

Batteries are the boring-but-essential parts everyone forgets to include. We make them. The ‘free’ is aspirational, not a pricing model. Some things cost money. We’re upfront about which.

1 / 8

What do you actually do?

Consulting, architecture, and open-source tooling. We design systems around how brains actually work—cognitive ergonomics applied to software. Fractional CTO engagements, infrastructure hardening, and modular packages you can install without buying a platform.

2 / 8

What’s ‘cognitive ergonomics’?

It’s the study of how humans process information under load. We apply it to software—reducing the invisible tax your interface charges every user, every session. Most teams treat cognitive overload as a frontend problem. The real bottleneck is usually three layers deeper.

3 / 8

Do you build full products or just consult?

Both. We do fractional CTO work for teams that need architecture guidance without a full-time hire. We also build and ship our own open-source modules. If it needs building, we build it.

4 / 8

What’s your tech stack?

Whatever the problem demands. We’re not a React shop or a Rust shop—we’re a ‘right tool for the job’ shop. That said, we have deep experience across the full stack: bare metal to product layer, with a bias toward systems that feel like thinking.

5 / 8

How do I work with you?

Hit the contact form or book a call. 30 minutes, no pitch, no deck. Bring your architecture diagram or a napkin sketch. We read every message and response time is hours, not business days.

6 / 8

Is everything open source?

Our tools and packages are. Consulting engagements and custom builds are not—those are paid work. We’re transparent about the line between free and paid. No bait-and-switch.

7 / 8

What does a typical engagement look like?

Week one: we read your codebase and talk to your team. Week two: you get a written assessment with prioritized recommendations. From there, we either hand off or roll up our sleeves—your call. No retainers, no minimum commitment. We earn the next month.
