It's crazy what happens when you listen to the community.

A few months ago I created a website called letsfg.co where you can get the best flights on the internet. Under the hood it runs hundreds of AI agents on my backend where each one is scanning a different website like Google Flights, Skyscanner, Booking, etc.

It then compares the prices and stats and gives you the best. And it now does the same with hotels.

The best part is that it's like Uber for travel - you can book hotel in 3 seconds.
It's the best thing I've built so far, here's why:

Just a month ago the whole team here behind letsfg were confused, building something people genuenly loved but hated the payment model. And everybody was asking for 1 thing - "make it free, I want to try it". But the infrastructure costs were killing us, this seemed impossible.

We managed to do it.

Quick update about flights and then hotels:
Previously we had a horrible payment model, upfront charge, nothing logical, just bad. Everybody asked us to change it. And instead of giving up because it seemed impossible we started thinking in first principles, got some deals done and today we're happy to say letsfg is free. Instead of charging you, we get the money from the airline ticket. And we still get you the cheapest tickets from the websites around the internet.

Today we also support hotels. It's on average 15% cheaper than booking_com, and you can book in 3 seconds, like an uber.

What's amazing is this is a big step in agentic commerce. Letsfg.co is agent native in it's core. This means that now also hotels, are bookable and searchable straight from your Claude, Codex, OpenClaw, Hermes, etc.

Authentication for AI agents is through payment method (was twitter auth before).

Everything is also available through our open developer API. For anybody interested in flights/hotels API: >!I believe this is a game changer, every provider out there requires hard flat fees upfront and long processes of contracting. We don't. Sign up to API and you get access to the context 10 seconds later.!<

How does it work?
We integrated with dozens of enterprise providers who gave us access to their hotels inventory and ability to book.
We also resued our approach from flights and polished it - AI agents navigating the hotel websites. Finally landing the right payment provider allows us to complete bookings on the hotel websites. GPT-5.6 Luna turned out to be an amazing engine for those agents.

How can I use it? 3 ways.

Website: letsfg.co best for everybody.

Programmatic Hotel Tool (PHT) and Programmatic Flight Search (PFS) - our agent native endpoints, best for AI agents, authentication done through payment method attachment (free, no charge, just for verification). This is what powers our Python package, NPM package, MCP, CLI, etc. best to check on https://letsfg.co/for-agents

Developers API - paid, balance based API, best for high volume. https://letsfg.co/en/developers

Thanks to everybody who shared their feedback, sweet and bitter, we read all of it and worked hard to make this great. You're awesome.

We'll continue making things better, tweaking the small stuff, and fixing the problems until we get joy back from travelling.

Cheers,

I've listened to your guys feedback. And it changed the world for this project.

letsfg.co started as a flight search native for AI agents, available through API, MCP, website, etc. It was always driven by community and if not the attitude from the community it would've been dead a long time ago.

Just a month ago the whole team here behind letsfg were confused, building something people genuenly loved but hated the payment model. And everybody was asking for 1 thing - "make it free, I want to try it". But the infrastructure costs were killing us, this seemed impossible.

We managed to do it.

Instead of charging you, we get the money from the airline ticket. And we still get you the cheapest tickets from the websites around the internet.

Today we're launching hotels. I am personally so excited for this, because it's like we're launching the Uber for hotels. Inventory of over 1 milion hotels, 15% cheaper than on booking_com, and the ability to book in 3 seconds.

Honestly it amazes me what great things can community make.

This is the best project I have ever made.
2 weeks ago I posted about my flight finder hitting 1.3k github stars sharing some of the stuff and thanking early contributors. That post got over 800 upvotes and 150 comments of feedback...

Through this 1 post I've learned more than in 3 months of running this project. (this post explains more about the API/programmatic access and dev stuff).

letsfg.co started as a simple webstite where you could find the best flights on the internet by comparing every other website in the world.
We've got so much overwhelming feedback, requests, problems with travelling.
Which got us to go back to our roots - what we are really here to do. Fix the travel experience.

We've worked on all of your feedback, listened to the problems and smacked our heads against the wall to tackle them.

We're going to comoditize travel management.

Thanks to your feedback we rebuild the whole searching experience on the homepage, where you're now able to search mutli-city trips, multi-departure trips, etc:

(couldn't put images for some reason now. check the 2nd image)

We build a compeltely new layer - ground transport. We will now show you transport options for each airport in the city, so you can choose the best:

(check the 3rd, 4th images)

This is my favourite, and I'm so excited about this. We've mapped the flights history from airlines, and will now show you reliability of each flight in your trip. Missed connection probability, and help with adjustments:

(check the 5th image)

But leaving you at this point wouldn't feel like we truly care.
So we will also monitor your trips 24/7, detecting disruptions, cancellations and delays, and instantly send you rebooking options, including free options from same-alliance flights.

We have changed the pricing like so many of you suggested, and added a subscription for frequent travelers. When you buy subscription, as a thank you, you get 4 free full-access trips for friends.

Everybody who bought previously keeps their access for a trip.

This project has evloved so much, and repeating myself, we really are aiming to fix the travelling experience, all the disruptions, cancellations and anxiety, especially when you need to be somewhere on time.
Travel management, comoditized.

And there is soo much more exciting coming, we're working on a partnership with Uber and add them to our ground layer transport.
We're on the last stages of signing an agreement with insurance and we'll work on providing that to all of members, so in case of cancellations - you're covered.
And as a last - we're working on automatic flight booking options, where when your flight gets cancelled, you don't even bother because we rebook the same-alliance - free option - for you.

This will all be available as openclaw, agent native, and API - we will be updating docs on the github repo in the following weeks. https://github.com/LetsFG/LetsFG

I can't thank you all individually, because at this point there is too many of you. 1.6k, wow.

But thank you, to everybody. Your amazing feedback and openness makes world-changing things possible. I Love the dev community <3

Keep on travelling.

Cheers,
Adam

It's crazy how the community responds when you build something amazing.

This is by far my most useful and succesfull project.
I made a website called letsfg.co where you can get the best flights on the internet. Under the hood it runs hundreds of AI agents on my backend, where each one scans a different website on the internet - Google flights, skyscanner, kayak, kiwi, etc.
It then compares the prices and gives you the best. I explained below why this works.

It's the best thing I've built so far in my 21 years of life, this screenshot shows why:

https://preview.redd.it/48gzmzprwdbh1.png?width=1902&format=png&auto=webp&s=7ef64462f54f6c110f87d29dea090c25a44a72fa

I'll explain below how it works.
And for anybody interested in using there are 3 ways:
- API
- regular website on letsfg.co
- Programmatic flight search (native for OpenClaw and other agents, complex name, but it's basicly an API, the difference is this one uses exactly our website but programmatically, to use this you need to auth by posting a challange code on twitter)

Why this works, and why I made it:
There's a hidden system called GDS where airlines wholesale tickets to websites that buy in bulk like kayak, skyscanner, trip_com, booking, etc. They get the tickets $100-200 cheaper and put their margin/fee on it. The bigger you are the better price you get. These websites compete with each other, so when there is high demand they would lower their own margin on purpose just to be the "best choice". So in short, to get the best price, you need to check the most number of websites.

I made this because I saw my sister-in-law take days of planning, 20 tabs in chrome of multiple websites at once just to make sure she got that flight ticket on the best price. I got reminded that I was guilty of the same thing. I think we love to travel, but we hate what's before the actual trip. Days of planning and stressing, instead of just going.
There is one more thing - I am incredibly obsessed with impacting the world, building a world-known company from Poland and organizing incredible events like Redbull.

I'm incredibly grateful for everybody who shared and continues to share feedback with us to make the service better. Thank you.

Oh, and we're on github: https://github.com/LetsFG/LetsFG

Their deal with the government felt apart. RIP

Hi there friends. Really excited to share the news about our open-source flight search, made by a small travel community I started.

2 weeks ago we had 420 github stars, this was a big milestone and we celebrated by spreading the word on reddit. The post went completely viral and we grew by 150 stars in 1.5 days.

The growth since has been completely crazy, all thanks to our amazing community. This is possible only by people finding issues, contributing, giving ideas, and searching for others (when you search you help the next person becuase the search is scanning websites like Skyscanner, Google Flights, Kayak, and others to find the best deal. And the person searching after you gets much faster and better results)

The flight search is made for native support of Ai Agents like Openclaw, Claude, etc.

Thanks to our amazing community and everybody who spread the love - you're making this possible. To anybody reading I want you to find this as an invite, to join, to build, to travel. LetsFG🔥🚀

2 weeks ago I posted about an opensource flight search from our small travel community. You guys took it viral. Today we launch a website.
https://www.reddit.com/r/software/comments/1sjkcg3/my_opensource_flight_search_just_crossed_420/

You guys are crazy. 2 weeks ago I posted about an open-source flight search that our small travel community made.

So many of you started chatting with it on messenger it almost fried our servers. We gained over 150 github stars in just 1 day, and went back to the cave to keep shipping and fixing.

Our travel community is growing, thanks to new contributors we managed to move even faster.
Today we're releasing something many people were asking for on the last post: a website.

Why is this big? Our search is agent native - 100% agentic. It's natively made for AI Agents like OpenClaw or CLI, Python package usage. Thanks to our sponsors we managed to host it on our own servers. From today on, you can use it much easier. Just directly on the website. Or, tell chatgpt to use it. Literally, no tools, chatgpt will use it like browsing the web.

When you search a few hundred of little ai agents will look at all the websites you would yourself. Like skyscanner, google flights, kayak, etc.

We're not stopping at all and need more friends to join. In the following weeks some of the stuff we will be releasing is:
- Preference chat based flight search (Imagine you're searching and have to answer this: Do you want a specific seat, for example 4 seats together, or random is okey - LetsFG flight search won't just find you the cheapest flight. It will find you the cheapest flight including the cost of choosing a seat.
- Complete cost transparency: Some airlines will show you the flight cost for $40 and then add additional $20 hidden fee at the checkout. Our page scanning will reveal hidden costs and give you the complete price directly in search.
- Dynamic ticket suggesting: Let's say you're buying a flight from London to Bali, 5th May, return 14th May. Have a flexy flight date? Maybe if you go on 7th May till 16th May you save $30.

We have so much more planned, all thanks to you and our amazing community. This is all opensource. LetsFG!
