A
Anti-bot
antibot system
protection
Software systems that detect automated traffic: Cloudflare, Akamai, PerimeterX, Datadome, Imperva. They analyse headers, fingerprints, TLS handshakes, behavioural patterns. The harsher the anti-bot, the more expensive the proxy you need (residential/mobile instead of datacenter).
D
Datacenter proxy
type
Proxies with IPs from server centres (AWS, Hetzner, OVH). Cheapest ($0.5-2/GB) and fastest, but easily detected by anti-bot systems via the ASN.
I
ISP proxy
Static residential
type
A residential and datacenter hybrid: IPs belong to real ISPs but are hosted in data centres. Fast like datacenter, looks like residential. Sold per IP rather than per GB.
L
Latency
performance
Delay from request to response through a proxy. Datacenter: 20-80ms, ISP: 50-150ms, residential: 100-500ms, mobile: 200-1000ms.
T
Throughput
performance
Requests per second through one proxy port without degradation. Datacenter: 100+ rps, residential: 10-50 rps, mobile: 5-20 rps.
W
Webshare
provider
A budget US provider. 10 free datacenter proxies for testing. The best entry-level option for indie developers.
