Hadaa

When we started building Hadaa, the plan sounded almost too simple: take a photo of someone's yard, run it through image-to-image generation, hand back a redesigned yard. In 2026 the generative part is basically a commodity — the renders look photorealistic out of the box.

That turned out to be the easy 20%. Here's what actually made the product defensible, in case it's useful for anyone building in the "AI does X" space.

The demo everyone can build. A raw diffusion model gives you a gorgeous render and nothing else. We could ship that in a weekend, and so could competitors. When we benchmarked 11 tools, almost everyone had stopped there. The problem: those pictures are unbuildable. The model draws what looks lush, not what grows — it'll cheerfully put tropical palms in a render for a yard that freezes solid every winter, and half the design is dead by spring.

Where the actual work was. The defensibility came from the boring layers around the model: (1) a constraint engine over generation — our "Biological Engine" resolves every plant to a real species checked against the user's USDA hardiness zone, rainfall, and frost dates. It's a data-and-rules system, not a prompt, which is exactly why it's been the hardest thing for competitors to copy. (2) Structured output, in reverse — turning an approved render back into a contractor blueprint and a bill of quantities. Pixels to priced data. (3) A pipeline, not a chat — one photo in; 22 renders + planting guide + blueprint + BOQ out, in under a minute.

The lesson I keep repeating to other founders: in most AI products right now, the model is the commodity and the moat is the layer that constrains it to real-world truth and emits something actionable.

What it turned into. On the homeowner side it's pay-per-project ($12, no subscription) — deliberately cheap, because the automation means we're not selling hours. On the pro side it's a closing tool for landscapers: generate the vision live in a client consultation and hand over a white-labeled buildable plan on the spot (full pro breakdown here).

Happy to answer anything about the build — the constraint-engine-over-a-generative-core pattern especially. It generalizes way beyond gardens. It's live at hadaa.app if you want to poke at it.

Hey IndieHackers,

I've been building Hadaa.app — an AI landscape design tool for homeowners, landscapers, and real estate agents.

Why it exists I bought a house, inherited a dirt patch, and spent weeks trying to learn SketchUp before giving up. A professional quote came back at thousands — just for a concept. I knew GenAI had reached the point where this problem was solvable, so I built the tool I needed. Turns out a lot of other people needed it too. We're now at 60,000+ users across 130+ countries.

The problem Most people can't visualize spatial changes to their outdoor space. Hiring a landscape architect costs thousands just for drawings. Generic AI tools like Midjourney generate beautiful images — but they don't understand your yard. They'll suggest tropical palms in Minnesota and give you zero planting guidance. Pretty pictures you can't build from.

What Hadaa does differently It's not a filter and it's not a mood board generator. Hadaa reads the depth, lighting, and existing structures in your photo — the fence line, the driveway, the facade — and renders a photorealistic 4K design that respects your actual space. Four engines under the hood:

• Style Engine — 48+ landscape styles applied to your real yard via one click or plain-English prompt

• Smart Fix — edit a single element by typing what you want; everything else stays untouched

• Sketch Engine — upload a napkin sketch or CAD file and get a photorealistic 3D render in minutes

• Biological Engine — every plant cross-referenced against your USDA hardiness zone, so nothing in your design will die in your climate

Every design also exports a contractor-ready planting guide and bill of quantities: botanical names, exact plant counts, cubic yards of mulch, square footage for pavers. You can hand it directly to a nursery or contractor.

Tech stack

• Rails 7 + Hotwire — fast, monolithic, no regrets

• Tailwind CSS

• Custom generative models for spatially-aware inpainting

What's working

• The Sketch Engine consistently surprises people — hand a rough drawing to an AI and get back a photorealistic render is genuinely magical to watch

• The Masking Brush gives users control that generic tools can't match — protect the oak tree you love, redesign everything else

• The planting guide output is converting well with professionals; landscape architects and contractors find it immediately usable

• 4.8 stars from 2,000+ reviews

The hard part Getting people to understand this isn't a photo filter or a style preset. The core value is spatial accuracy and biological validity — a design you can actually build, with plants that will actually survive. That's a harder thing to communicate in a headline than "make your yard look pretty."

Would love feedback on how we're telling that story. Landing page: https://hadaa.app/

ALTERNATIVETO LISTING

Hadaa is a purpose-built AI alternative to landscape CAD tools like SketchUp, general image generators like Midjourney, and consumer apps like iScape or DreamzAR. Where CAD tools require weeks of learning and generic AI ignores your actual yard, Hadaa is trained specifically for exterior landscape design — combining spatial reasoning, botanical data, and climate science in a single browser-based workflow.

Pros over CAD (SketchUp, AutoCAD) Photorealistic renders in 60 seconds vs. days of modeling. No 3D skills required. Accepts hand-drawn sketches and CAD exports as input and converts them to 3D renders automatically.

Pros over generic AI (Midjourney, Stable Diffusion) Reads and preserves your existing yard geometry. Validates every plant against your USDA hardiness zone. Outputs a contractor-ready planting guide and bill of quantities — not just an image.

Key features
