Gestor de proxies
Software que centraliza y automatiza el uso de proxies - rotación, reglas de enrutamiento, reintentos y configuración por destino - en todo tu pool.
Un gestor de proxies es software que se sitúa entre tus scrapers y tus proxies, automatizando cómo se usan los proxies. En lugar de programar la lógica de proxy en cada script, apuntas tus herramientas al gestor, que en un solo lugar maneja la rotación de IP, las reglas de enrutamiento por dominio, los reintentos ante fallos, la gestión de sesiones y el registro.
Resuelve el caos de gestionar proxies a escala. Sin un gestor, cada scraper reimplementa la rotación, la detección de bloqueos y la lógica de reintentos. Un gestor de proxies centraliza esas preocupaciones: define las reglas una vez -rotar cada N solicitudes, usar IPs residenciales para este dominio y de centro de datos para aquel, reintentar fallos con una IP nueva- y todas las herramientas se benefician.
Las funciones varían pero suelen incluir rotación automática, control de sesiones sticky, selección de proxy por destino, reintentos y fallbacks de solicitudes, analítica de ancho de banda y tasa de éxito, y comprobaciones de salud que descartan IPs muertas. Algunos son herramientas de código abierto que alojas tú mismo; otros vienen integrados en los paneles de proxy comerciales.
Necesitas un gestor de proxies cuando tu operación supera la simple configuración por script - varios scrapers, varios destinos y reglas que difieren por sitio. Para un único scraper pequeño que apunta a un solo destino, el gateway del proveedor con rotación integrada suele bastar por sí solo.
The layer that decides which address runs the next request
A proxy manager sits between your code and your proxies and answers one question repeatedly: which address should this request use. Around that it usually adds health checking, retry handling, rotation policy and per-address statistics.
It becomes worth building or buying at the point where you have more than one type of proxy and more than one kind of target. Routing public pages to cheap datacenter addresses and protected pages to residential is a decision that has to live somewhere, and hardcoding it into every scraper does not scale.
The other job is memory. Recording which address served which response, and what happened, is what turns a vague sense that things are getting blocked into a specific list of addresses to rest and targets to reroute.
What to route where, with our products
A manager is only as good as its routing table. This is a sensible starting one:
Routing policy
Public pages, no filtering -> datacenter pool, cheapest per byte
403 on first request -> residential, retry once
429 -> same type, different address, back off
Login flows -> ISP or mobile, one address per account
Geo-specific checks -> residential with _c_ and _city_- Log the address with every response. Without it, you cannot distinguish a bad address from a bad target.
- Implement backoff per address rather than globally. One rate-limited address should not pause the whole run.
- Health-check static addresses on a schedule, because an expired or replaced address fails silently.
- Our API exposes what a manager needs: GET /proxies for the fleet, and the residential endpoints for gateway credentials.
Manager design mistakes
Retrying on the same address
The most common bug. A retry after a block should change the address, and often the type.
Global backoff
Pausing everything because one address hit a limit wastes the rest of the fleet.
No provenance
Without per-request address logs, every diagnosis is guesswork.
Rotating on every request by default
Sites that expect a returning visitor treat that as the anomaly. Route by target instead.
