I built a site that tracks short-lived flight deals
So, this summer I was hunting for a flight from Calgary to Tokyo with WestJet, and I kept seeing these random cheaper flights popping up. I got tired of refreshing the site non-stop, so I whipped up a script to scrape the flight data. It paid off—I scored a roundtrip for $1000 CAD in July! Naturally, I decided to turn this into a full-fledged project and built flight-price-alert.com! Tech details: Built with Go for the backend and SQLite for the database. Added some TLS spoofing to get around Cloudflare’s JA3 fingerprinting that was blocking my requests. Styled the site with PicoCSS—it was…
In plain words
Flight-price-alert.com monitors flight prices and notifies users when cheaper fares appear for their desired routes. Built for travelers who want to avoid constantly checking airline websites, the tool scrapes flight data and alerts users to short-lived deals. It uses Go and SQLite for backend processing and is designed to catch price drops like the $1000 CAD roundtrip from Calgary to Tokyo that inspired its creation.

So, this summer I was hunting for a flight from Calgary to Tokyo with WestJet, and I kept seeing these random cheaper flights popping up.

Added some TLS spoofing to get around Cloudflare’s JA3 fingerprinting that was blocking my requests. Styled the site with PicoCSS—it was super easy and kept things neat. Generated tons of images with Recraft.ai. Seriously, I must’ve churned out hundreds. It was a blast! Hosted on a single EC2 instance with EBS attached for SQLite storage. It’s pretty simple right now, and I’m debating whether to keep developing it or move on. If you have any questions or ideas for improvements, I’d love to hear them!

- THTravel Hacking Toolkit – Points search and trip planning with AIApr 2026 · github.com · ▲95
I use points and miles for most of my travel. Every booking comes down to the same decision: use points or pay cash? To answer that, you need award availability across multiple programs, cash prices, your current balances, transfer partner ratios, and the math to compare them. I got tired of doing it manually across a dozen tabs. This toolkit teaches Claude Code and OpenCode how to do it. 7 skills (markdown files with API docs and curl examples) and 6 MCP servers (real-time tools the AI calls directly). It searches award flights across 25+ mileage programs (Seats.aero), compares cash prices…

Hey there HN! We’re Joe and Stopa, and today we’re open sourcing InstantDB, a client-side database that makes it easy to build real-time and collaborative apps like Notion and Figma. Building modern apps these days involves a lot of schleps. For a basic CRUD app you need to spin up servers, wire up endpoints, integrate auth, add permissions, and then marshal data from the backend to the frontend and back again. If you want to deliver a buttery smooth user experience, you’ll need to add optimistic updates and rollbacks. We do these steps over and over for every feature we build, which can…
