Self-hosted house planner
Plan the house. Plan the wiring, plumbing, sewer, and heat too.
Home Builder AI is a house planner you run on your own server. True-scale 2D plan, 3D view, satellite overlay, four utility networks, and a priced bill of materials. No subscription. Your plans never leave your server.
$129 one-time. $99 at launch. One payment, no monthly fee. A hosted version is coming — see Pricing for the waitlist.
What it does
Most planners stop at walls and furniture. Home Builder AI keeps going — into the systems inside the walls and the cost of building them.
2D editor, true scale
Draw walls with real thickness and materials. Doors, windows, garage gates, furniture at real sizes. Snapping, dimension lines, a measuring tool, room areas worked out from the walls. Imperial and metric — switch any time.
3D view
See the plan in 3D in two looks: a clean Model view and a Materials view with finishes. Low-wall modes let you read the layout from above. Wall colors from the RAL palette.
Satellite and site
Put the plan on satellite imagery of your lot. Set the lot boundary from a GeoJSON parcel file. Check setbacks, footprint, and coverage against the real ground.
Utility networks
This is the part the others skip. Electrical with circuits, breakers, and load and voltage-drop checks. Water supply with manifolds and home-run piping. Sewer with slopes and invert levels. Underfloor heating with loop layout and balancing. Each network is its own layer, with its own checks and its own section in the estimate.
Priced bill of materials
Quantities come straight from the plan and the networks. Prices come from a catalog file you control, in USD. Print it as a shopping list, export CSV, check items off as you buy them.
Self-hosted storage
The plan lives on your server as a file. Every save is a numbered version, plus named snapshots you can restore. One password protects it. Phones get a read-only view for the job site. No account with us. No cloud.

Install
Two ways to run it. Both keep the plan on hardware you control. No database either way.
Docker — one command
docker compose up -d --buildOpen the site, run the setup wizard once, set one password. Done. Data lives in a Docker volume and survives rebuilds.
PHP hosting
- Any hosting with PHP 8.1+ and Apache or LiteSpeed with mod_rewrite. nginx works with one extra rule — see INSTALL.md.
- Build once on your computer, upload the
dist/folder, run the setup wizard. - No database. No Node.js on the server.
FAQ
Is it really one payment?
Yes. $129, or $99 at launch. No subscription. Minor updates for this version are included.
Where do my plans live?
On your server, as files, behind one password. Nothing is sent to us. If your server is off, your plans are on your server — back up the storage folder and you have everything.
Do the network checks replace an engineer?
No. The electrical, sewer, water, and heating checks are reference checks. They catch common mistakes early. Final designs have to meet the NEC and your local code, and licensed work needs a licensed pro.
Are the catalog prices real?
They are example US prices in USD to get you started. Edit the catalog file with prices from your suppliers. Your totals are only as good as the prices you put in.
What do I need to run it?
Docker, or PHP 8.1+ hosting. A current browser with WebGL 2. Node 22 is only needed if you build from source.
Can I view a plan on my phone?
Yes. Phones get a read-only view of the current plan. Editing is done on a computer.
