We Make the Batteries.

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

CellState \u2014 memory and orchestration for agents. More on the line.

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

How We Work

Architecture advisory. Cognitive ergonomics. Infrastructure hardening.

Cognitive Ergonomics Audit

We identify the friction your product quietly imposes on users — context switching, ambiguity, memory load, broken flow. Three friction points minimum, usually more. Then we show you where they are and how to remove them.

Architecture Advisory

Real architecture review, real code, real decisions. Technical direction for teams that need clarity without adding another full-time executive title.

inquire@freebatteryfactory.com

Infrastructure Hardening

CI/CD, containers, monitoring, recovery drills. The unglamorous systems work that keeps production from becoming folklore and your 3 AM self from getting paged.

For Developers

CellState docs, API reference, and source code.

Memory and orchestration for agents. Built to feel like thinking, not like caching.

Open Source & Education

No price tag. No platform tax. Compose however you want.

Self-contained packages that handle one concern well. No bundle theater. No platform tax. Compose them however you want.

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 people actually think and how real systems actually fail. Architecture advisory 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 architecture advisory work for teams that need technical direction 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?

The 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 the people who built it. 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.
