The 12-hour Airbnb product
estimertravaux.com turns renovation photos into itemized French-market estimates in seconds. OpenCrabs is the brain doing it all: vision analysis, SKU selection, pricing, planning, the whole SKU-to-budget pipeline, orchestrated as an autonomous agent.
EstimersTravaux is Gaspare Russo’s estimation app for the French renovation market: clients photograph their rooms, pick rooms and trades, and get a detailed per-room estimate based on real 2026 French market pricing in seconds.
- OpenCrabs as the brain: the Dart bridge invokes the OpenCrabs CLI (v0.3.83) as an autonomous agent (
opencrabs run --auto-approve) and delegates the entire estimation to it - SKU orchestration: the agent reads the photos, selects product ranges coherent with the property’s usage and style from a per-trade brand catalogue (Tollens, Legrand DX3, Uponor, Porcelanosa, Grohe, IKEA…), estimates quantities, and emits per-room line items with min/max ranges
- Real market smarts: regional multipliers (Côte d’Azur ×1.18, Paris ×1.25), adaptive TVA by building age, conditional purchase orientation, rental units get Leroy Merlin ranges, high-end gets Point.P premium and Villeroy & Boch
- Strict output contract: the agent returns pure JSON (rooms + line items + planning); the bridge extracts it via bracket-matching and persists everything in PostgreSQL
- Zero hardcoded fallback: if the AI fails, the user gets an explicit error and a retry, no fake numbers
The origin: built in 12 hours in a Lisbon Airbnb by Gaspare Russo with Carlos Eduardo (heyiolo.com) and Adolfo Usier, OpenCrabs’ creator. During the build, OpenCrabs also translated the team’s French↔English conversation live on a dedicated Telegram group, and worked beautifully.
