24 alternatives to Spelt
I was frustrated with existing APIs for searching flight prices, so I built this. It's a simple API to search for flights and get their prices. It can also return booking links. Generous free tier (happy to give more credits, lmk) + super low pricing. Lmk any thoughts or improvement ideas :)

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…

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…
