Data
We aim to monitor the shops every day. But, sometimes something breaks, and it might take a while to fix it.
We are checking the quantity and quality of data ourselves, but you are always welcome to report any issues.
About this project
π€ Is it like hlidacshopu.cz?
Exactly!, but:
β’ Hlidac is focused only on Czech & Slovak market, at least for now!
β’ Hlidac is more robust β it runs for years, on a proper infrastructure, with a team of people.
π¬ Are the data correct & complete?
Completeness β aim is the monitor the prices every day. But, it's just a pet project β if the monitoring script fails, it might take a while to fix it. If the cloud bills get too high, it might pause for a while. Correctness β there's no reason for the data to be wrong, but there's also no guarantee they are correct! I do my best, but that's all.
π Supported shops?
Basically the shops I like & use. I'm open to suggestions, though.
