VPSPriceTracker.com is a complex search engine for VPSs (Virtual Private Server) where thousands of servers can be searched and filtered using several search parameters, like server location, CPU type and size, storage, and others.
The database currently contains 60,000 VPSs that are fully searchable using these tunable knobs, and is completely refreshed from scratch with live data every day. The data is then plotted in charts to track the variation of price and stock availability of each server over time. One of the cool search filters is whether cryptos can be used to buy the server, including Bitcoin.
And that's really it. Hope you'll find it useful!
