Halifax fuel price predictions, automated.
What is this?
Every Thursday, a Reddit user named u/buckit posts the upcoming week’s Halifax gas and diesel price predictions to r/halifax. This site automatically finds that post, reads the numbers, and displays them in a clean format — so you don’t have to dig through Reddit.
This project was entirely created, deployed, and maintained solely via AI prompts. The only human interaction was purchasing the domain name. Zero lines of human-written code or documentation.
How does it work?
A Cloudflare Worker runs every 15 minutes (every 5 minutes on Thursdays). It fetches the newest posts from r/halifax and looks for u/buckit’s prediction — the weekly Thursday post, or a mid-week interrupter clause. It parses the markdown table for regular and diesel prices, then stores the result and updates this page, all automatically with no human in the loop.
The site also handles interrupter clause posts — when the Nova Scotia Utility and Review Board issues an emergency mid-week rate adjustment, those posts are caught too, any day of the week.
The meme image
When prices go up or down (not “no change”), the Worker generates a meme image using Cloudflare Workers AI — specifically the Flux 1 Schnell text-to-image model, which runs entirely in Cloudflare’s infrastructure.
The prompt is built automatically from two sources: the price direction (up = despair, down = celebration) and the top posts from r/halifax and r/novascotia that week — excluding u/buckit’s own prediction post. Whatever Halifax and Nova Scotia are talking about — potholes, storms, local events — becomes the backdrop for the meme. Very Canadian.
The caption below each image shows the model used and links back to the Reddit post that triggered the generation. Tap View AI prompt to see the exact prompt that was sent to the model.
Images are stored in Cloudflare R2 and served directly from this site with no third-party CDN. The whole thing — Worker, AI, storage — runs on Cloudflare’s free tier. The only cost is the domain name (at wholesale Cloudflare prices).
Who made this?
A developer with the moniker program-the-brain-not-the-heartbeat from Cape Breton, Nova Scotia who got tired of searching Reddit every Thursday. The source code is open-source (MIT licensed) on GitHub.
Is the data accurate?
This site displays community estimates posted by u/buckit. The author of this site has no affiliation with u/buckit and cannot verify the accuracy of the predictions. Prices may be off by a cent or two (“May be +/- 0.1”). Not financial advice. Always confirm at the pump.
