Rentay
A technical user can build a narrow, usable rental search and booking workflow, but reproducing Rentay's supply, reviews, partnerships, and market coverage is impractical; keeping the paid service may be preferable for full product scope.

No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Rentay alternatives, with the arithmetic →
What a replacement has to do
- Provide searchable rental listings, compare providers and prices, allow bookings/reservations with provider onboarding, user accounts and favorites, map view for locations.
What it still won’t have
- brand recognition and user trust accumulated by Rentay
- market coverage and the supplier network (many listed providers)
- existing user reviews and historical transaction data
- affiliate and partner integrations Rentay already has
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal rental-aggregator web app using Next.js (React) + Postgres + ElasticSearch, deploy on Vercel/Render and managed Postgres (Supabase or Render DB). Core features in scope: (1) admin import/ETL to ingest and normalize CSV or provider API listings into Postgres, (2) searchable listings with faceted filters and map view (Leaflet + Mapbox), (3) listing detail pages with availability, (4) booking/reservation flow with Stripe payments and provider notification emails, (5) user auth, favorites, and basic provider onboarding dashboard. Out of scope: multi-language support, affiliate network integrations, high-volume scaling, mobile apps, advanced recommendation engine. Include error handling, input validation, and automated tests for ETL, search, booking flows, and payment webhook handling.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 2 cited sources+1
- Evidence score58
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
