I'm a developer based in Paris. I built a budget-first travel discovery tool. Would love feedback from travel people.
Most travel search starts with “where do you want to go?” I’m exploring the opposite: “I have 7 days and €800, where can I realistically go?”
The site is spontaneous.travel. It’s discovery-first, not a booking engine: fares are recently observed or estimated, and users verify final prices on Aviasales.
I’d especially love feedback on: - whether this solves a real travel-planning pain - whether the price labeling feels honest - what travel professionals would expect before trusting this
Hi Christophe, thanks for sharing spontaneous.travel with the Travel Massive community and joining us. This is a really cool tool, bravo!
I love the combination of flights and hotel estimated costs. The "cheapest trips / destinations" section is my favourite part and very helpful (e.g. spontaneous.travel/from/melbourne) and the UX feels really focused on helping the user solve a problem and get results fast.
My only design feedback is the primary brown/orange colour could be swapped for something more poppy like a purple/pink gradient. And a dark mode option please 😎
Thanks for the kind words and the detailed feedback, really appreciated.
On Aviasales: I use the Travelpayouts API for flight data, and Aviasales is their main consumer brand (same company). I've looked at other APIs but most have an active user threshold you need to hit before they'll let you in the door. Since I'm still early, that's a non-starter. Travelpayouts was the rare one that let me start small and scale up. I was planning on using Amadeus self-service, but they are shutting that down.
Re: the color I am with you on it ! I won't pretend I spent months on design. The amber/brown actually came from early Claude prototypes and I just stuck with it. You're right that it could pop more. I also specifically wanted to avoid blue because Skyscanner, Google, and Meta already own that space. Your purple/pink gradient idea is solid, I'll keep it in mind for a proper redesign down the line.
On that note, you don't happen to know anyone at Kiwi or Skyscanner (or any other API providers) who could help with API access? Most of the big players gate their APIs behind traffic thresholds and I'm not quite there yet. A warm intro would go a long way.
I built a website that turns your budget and dates into a list of spontaneous trip ideas (flights and hotel)

I actually build something pretty similar, great minds think alike.

What made you go with Aviasales?
