Local-first agentic AI coding

More than a suggestion.
A workflow you can review.

Buildroom brings local model choices, repository work, reviewed changes, and verification receipts into a Windows application. The goal is useful software engineering with visible boundaries—not an unbounded agent session.

Start with FREE EDITION on compatible hardware. Read what agentic coding means, then compare the edition roadmaps. FREE and early Autopilot workflows continue to be hardened; a future feature is not a current-release promise.

Capability should not feel like a closed door

Understand it.
Try it. Build on it.

Buildroom starts with real work: understanding a project, untangling an error, drafting a useful script, or shaping a small idea into code.

The broader engineering direction goes further: clear scope, reviewable changes, verification, proof, and recovery. Different editions deliver different levels of that experience. A model sounding confident is not the same as a job being finished.

Announcement · September 5, 2026

We are making FREE a bigger deal.

3B, 4B, 7B, and 8B are included in FREE EDITION 1.8.5. Read the update.

Actual FREE EDITION interface

Buildroom, as it actually opens.

This supplied FREE EDITION capture shows the product introducing local use in plain language, asking how the person wants explanations delivered, accepting a project, and returning a visible receipt instead of pretending a non-repository is ready to commit.

01 / Approachability

Plain language first.

The welcome explains local setup and asks how detailed the answers should be.

02 / Local control

Nothing downloads silently.

The person chooses when to set up a model and when to bring in a project.

03 / Receipts

The real state wins.

A non-Git folder is identified as a non-Git folder, with the next visible action explained.

Start with something useful

A little help.
A lot more possible.

You do not need a grand plan. Start with a question, a small project, or that one task you keep putting off.

01

Understand the code.

Make unfamiliar projects a little less intimidating. Ask what a function does and why it works.

Explain this function in plain English. Walk me through the inputs, outputs, and possible edge cases.
02

Make a useful script.

Turn a repetitive job into a practical starting point. Read and test the result before running it.

Help me draft a PowerShell script that lists files by size. Start with a read-only version.
03

Start something new.

Give that idea a first shape: a simple page, a small component, or a front-end scaffold.

Help me create a simple HTML and CSS landing page for a local business. Keep the code easy to edit.
04

Untangle an error.

Bring a confusing error, log, or configuration. Ask better questions and find your next step.

Explain this error, identify the likely causes, and suggest the smallest safe check to try first.

Starter ideas, not guaranteed results. Review generated code and test changes before using them. Model availability and performance depend on your hardware and installed release.

Clear answers. No fine-print maze.

A few things
worth knowing.

All questions & answers
Is FREE EDITION actually free?

Yes. Mainely Code Buildroom—FREE EDITION is available for $0 on the Microsoft Store . You do not need a paid Buildroom edition to start using it. Your PC, storage, and electricity are still your own resources.

Are 3B, 4B, 7B, and 8B all available today?

Yes. Mainely Code Buildroom—FREE EDITION 1.8.5 includes 3B, 4B, 7B, and 8B local model choices today. The best fit still depends on compatible hardware, available memory, and the task. Check the Microsoft Store listing and the installed release notes for the exact model catalog and requirements.

Will it work on my computer?

Buildroom is a Windows desktop app. Check the current Microsoft Store system requirements before installing. Model performance depends on available memory, processor, graphics hardware, and workload. Supporting an 8B model does not mean every PC can run it comfortably.

When are LITE and ADVANCED coming?

LITE and ADVANCED are in active development. Their public availability, final capabilities, hardware requirements, and pricing will be announced only when their respective release qualification is complete. The current Microsoft Store product available today is Buildroom—FREE EDITION 1.8.5.
