Mainely Code Buildroom

AI coding.
On your terms.

A local-first coding workspace for understanding, planning and doing real project work. Keep your hardware in the loop, your approvals visible and your results open to review.

THE ENGINEERING WORKSHOP

Ambition, assembled.

An idea takes shape through scope, coordinated work, review, and evidence. Product capabilities remain specific to each edition and release.

Illustrative motion · human direction remains at the center.

More than a chat box

Bring the project. Keep the context.

01 / UNDERSTAND

Talk through the work.

Ask about a repository, explain a failure or work toward a bounded change. Keep the requirement and the target clear.

02 / CHOOSE

Use your local compute.

Select approved model choices that fit your edition and machine. Larger does not automatically mean better for every task.

03 / VERIFY

Review what happened.

Keep action scope, results and verification evidence visible. A confident answer is not the same thing as a passing test.

AUTOPILOT · ALL EDITIONS

Automation.
Not “good luck.”

Autopilot is about doing the approved work—not just describing the clicks. Supported browser and desktop workflows stay bounded by the actions you authorize.

Multi-step navigation, waiting for interfaces, clearer feedback and stronger recovery are active areas of improvement across FREE, LITE and ADVANCED.

Supported actions depend on the installed release, target application and permissions. Stop does not undo an action already completed.

Real utility starts at FREE.

BUILDROOM

Available on Microsoft Store

FREE

$0

A real local coding workspace. Not a timer. Not a trial.

  • Approved local model choices through 8B
  • Project context, conversation and hardware visibility
  • Autopilot with reviewed actions

BUILDROOM

Available on Microsoft Store

LITE

Own your license

More headroom for capable gaming, CAD and development PCs.

  • Larger model catalog, including 20B choices
  • The familiar local Buildroom workspace
  • Perpetual license; current pricing in Store

BUILDROOM

In development

ADVANCED

Go further

Heavier engineering workflows and governed worker coordination.

  • High-capacity local-model workflows
  • Drone Swarm and controlled LAN worker direction
  • Release qualification in progress

Available models depend on your installed version, approved catalog and hardware. Store availability does not mean every development feature has shipped. Check the listing for current price, version and requirements.

Next-update work

More from the models you have.

The current engineering work brings GRIND and the CLI further into the Buildroom experience. Delivery is qualified separately from the already-available Store releases.

GRIND

FREE is getting the GRIND.

The next FREE update expands bounded, iterative work instead of reserving the idea for the highest tier.

BUILDROOM CLI

Your terminal. Same Buildroom.

A command-line surface alongside the desktop, with the same edition-specific capabilities and approval boundaries.

AUTOPILOT

Better continuity. Clearer results.

Natural navigation wording, stronger recovery, durable conversations and source-bound verification are part of the current work.

ADVANCED · In development

More capacity. Not less control.

The next level:
Drone Swarm.

Governed coordination across the workers you authorize. ADVANCED brings heavier workflows and controlled LAN execution into the development picture.

Worker distribution and capabilities remain subject to release qualification. No standalone worker download is advertised here.

Powerful AI. For the People.

Your machine. Your work. Your build.

Start with FREE. Try a real project. Check your hardware before choosing a paid edition.

MAINELY CODE / PRACTICAL GUIDANCE

A local AI coding assistant belongs inside a reviewable workflow.

An agentic coding workflow connects project understanding, a bounded task, permitted actions and a checkable result. Buildroom brings local model choices and project context into that workflow. Its Autopilot actions remain subject to the controls and capabilities of the installed edition and release.

  1. Choose one useful task. Start with an explanation, a small bug fix or a clearly scoped change. Identify the repository and the behavior you want to preserve.
  2. Give the assistant relevant context. Point to the files and acceptance criteria that matter. Review its understanding before expanding the task.
  3. Review actions and changes. Check commands and proposed edits against the task. Approval for one step is not blanket permission for unrelated work.
  4. Inspect the evidence. Read the diff and the checks attempted. A confident answer does not establish that a test passed or a deployment succeeded.

Local inference and connected services are different choices.

Local inference uses a supported model on your compatible machine. Model downloads, browsing and connected services can require internet access. Review where inference runs and what a specific service can access; a desktop app is not a promise that every optional workflow stays offline.

Pick an edition for the work and the machine.

FREE offers approved local models through 8B. LITE expands the approved catalog, including 20B choices, with a perpetual license. ADVANCED is in development for heavier engineering and governed worker coordination. Larger models still need suitable memory and compute headroom.
