This Free Tool Tracks Flight Prices Over Time — I'd Have Saved ₹25,000 on My Last Trip

TamilTech AI summary

Fairtrail is a free, open-source flight price tracker you run yourself that repeatedly checks the routes you care about and builds a real history of how fares move over days and weeks, instead of only showing today’s snapshot like Google Flights or MakeMyTrip. That matters because Indian and international tickets swing hard with dynamic pricing, and one writer reportedly saved about ₹25,000 on a single trip by booking when the log showed historically low prices rather than guessing or panic-buying. You set it up with Docker on a always-on machine such as a Raspberry Pi, an old laptop, or a cheap VPS, add a Gemini or OpenAI API key (or a local LLM), then describe routes in plain language and let it log prices in the background. What you should know is that it is not a simple Play Store app—you need basic comfort with the command line—but frequent travelers can offset a small VPS cost quickly, and running it on your own gear also keeps your search plans more private than big booking sites. In short, watch the trend for a week or two before your window, then book when prices sit near the lows for that route.
