PYProxy alternative: what changes if you move to Nefo

What PYProxy sells and does well

PYProxy is a price-led, high-volume proxy vendor with an unusually wide catalogue for its tier. Alongside rotating residential bandwidth it sells flat-fee "unlimited" residential plans on dedicated proxy servers, static ISP proxies in both shared and dedicated form, dedicated datacenter IPs, and a per-IP SOCKS5 product with its own desktop client. Coverage spans most of the world with noticeably good depth across Asia-Pacific, and the account layer is generous — large sub-account and whitelist allowances, username/password or IP whitelist authentication, and an API for usage and account management.

That breadth is the real argument for PYProxy. If your work spans several proxy types, buying them from one vendor with one balance and one dashboard is a genuine operational saving, and PYProxy is one of the cheaper places to do it at volume. The common criticisms are also worth knowing before you decide: support is email-led and can be slow, refund handling is strict, and consistency across the residential pool varies between tiers — which is normal for any network of that scale, but it means you should benchmark against your own targets rather than trust headline figures.

Nefo no longer competes as a two-product catalogue. It now sells residential bandwidth, mobile ports on real carrier modems, datacenter proxies, fixed static IPs and static residential ISP IPs in 24 countries, but it does not try to mirror PYProxy's per-IP SOCKS5 client workflow. If you need three or four proxy types under one roof and that mix includes the S5 client, PYProxy is the better structural fit and this page is unlikely to change your mind.

• Things PYProxy sells that Nefo does not: shared static ISP proxies
• A desktop client for browsing and binding individual SOCKS5 IPs to local ports
• Flat-fee "unlimited" residential plans on dedicated servers

PYProxy S5 client vs Nefo proxies

PYProxy's most distinctive product is not its rotating residential pool — plenty of vendors sell that — but its SOCKS5 offering and the Windows client that drives it. You filter the pool by country, state and city, pull back a list of individual IPs, pick specific ones and bind them to local ports on your machine. Billing is by IP count rather than by gigabyte, and you buy IPs in blocks.

That is a fundamentally different workflow from metered bandwidth. It suits multi-accounting and antidetect browser setups, where each profile wants one IP that it holds, reuses and recognises, and where per-GB metering is both the wrong unit and a source of constant anxiety. If that describes your operation, PYProxy's client is doing real work for you and there is no equivalent on the Nefo side.

Nefo has no desktop application, no per-IP purchasing and no local port binding. Its SOCKS5 support is protocol support: you generate a credential with targeting and session behaviour attached, and point your software at it. That is a good fit for scrapers, monitoring jobs and automation, and a poor fit for someone managing a hundred browser profiles by hand.

Validity windows vs non-expiring bandwidth

This is the structural difference that motivates most of the switching we see. PYProxy's rotating residential traffic is sold against a validity period — the balance is tied to a window that begins at purchase, so unused gigabytes do not roll forward indefinitely. Check the current term on whichever plan you are considering, as vendors adjust these. Their static IP products are not metered this way.

Whether that matters depends entirely on the shape of your consumption. If you run a steady scraping load that burns a predictable amount every month, a validity window costs you nothing and you should ignore this section. If your usage is bursty — seasonal price monitoring, client-by-client project work, QA cycles that go quiet for a month — you end up buying to a peak and paying for the troughs.

Nefo's flexible plans are non-expiring. Bandwidth sits in the account until traffic actually passes through it, generating credentials is free, and you top up when you need to rather than on a clock. The other shape difference is the entry point: PYProxy's attractive per-gigabyte rates are volume rates, with small pay-as-you-go purchases sitting on a considerably higher tier. Nefo starts at 5GB for $4.50 ($0.90/GB) and the rate moves down gradually with volume, which makes small and irregular purchases less punitive.

• Non-expiring bandwidth matters most when: usage is seasonal or campaign-driven
• You bill proxy traffic through to clients on irregular projects
• You want to buy once and test properly before committing budget
• You keep a reserve balance for incident response or ad-hoc verification
• It matters least when: you run a constant, predictable monthly scrape

How Nefo residential proxies work

The residential product is deliberately narrow. You buy prepaid bandwidth, generate credentials in the dashboard, and consume the balance as traffic passes. Credentials work over HTTP, HTTPS or SOCKS5, authenticated by username and password or an IP allowlist. Targeting covers 227 countries and territories, with the United States addressable down to state and city, region and city level in selected countries including the United Kingdom, Canada, Germany and France, and ASN/ISP targeting so you can pin traffic to a specific network operator within a country.

Sessions come in two forms. Rotating gives a new IP on each request, which is what you want for wide distributed collection. Sticky holds the same IP from one minute up to twenty-four hours, configured per credential, for logins, multi-step flows and checkout paths. Credentials can be generated in bulk and exported as CSV, which is usually how people wire a fleet of workers.

The mobile line is a separate product and a different billing model to almost everything in PYProxy's catalogue: a 4G/5G port on a real carrier modem with one live carrier IP that you keep or change on demand, rented by duration from hours up to thirty days rather than metered per gigabyte, with US state and carrier-level targeting available.

• Protocols: HTTP, HTTPS, SOCKS5 — username/password or IP allowlist
• Targeting: 227 countries and territories, US state and city, ASN/ISP within a country
• Sessions: rotating per request, or sticky from 1 minute to 24 hours
• Plans: prepaid from 5GB, non-expiring, free credential generation
• Mobile: 4G/5G port on a real carrier modem, rented by time, not by bandwidth

How to migrate from PYProxy without rewriting your stack

For the rotating residential half, the move is mostly mechanical. Both providers speak standard HTTP, HTTPS and SOCKS5, so in most codebases you are changing a host, a port and a credential pair. Scrapy, Playwright, Puppeteer, curl and the usual antidetect browsers all take the new endpoint without modification.

Two points are worth checking. First, Nefo accepts a username and password or an IP allowlist, so whitelist-based setups can keep that approach once your server IPs are registered. Second, targeting and session behavior are written into the username, for example -country-us, -city-losangeles and -session-<id>, so map out your target segments first and set up one username pattern per segment, then load them into your worker configuration.

The sensible sequence is to buy the smallest plan, generate a handful of credentials against your two or three hardest targets, and run them in parallel with your existing PYProxy setup for a few days. Compare success rate and latency on your own workload rather than on anyone's benchmark. Nefo also sells static residential ISP IPs in 24 countries, so ISP workloads can be tested too, alongside datacenter and fixed static IPs, if those shapes fit what you are running.

• Re-register your server IPs for allowlist auth, or switch to username/password
• List your target segments — country, state or city, ASN — before generating
• Use one username pattern per segment
• Choose rotating or sticky per credential, with a session length that matches the flow
• Run both providers side by side on your hardest target before cutting over
• Test static ISP and datacenter workloads separately from residential

PYProxy or Nefo: how to choose

Stay with PYProxy if your operation depends on catalogue breadth or on the per-IP workflow. That covers anyone running classic static ISP proxies next to residential, anyone whose multi-accounting depends on the S5 desktop client and holding named IPs per profile, anyone getting real value from a flat-fee unlimited plan because per-gigabyte metering is the wrong unit for continuous throughput, and any team relying on the large sub-account and whitelist allowances. Consolidating those onto a narrower provider would be a downgrade.

Move to Nefo if you mainly used PYProxy for rotating residential traffic and the rest of the catalogue was noise, or if you also want datacenter proxies, fixed static IPs or a way to keep an address without relying on PYProxy's S5 client. The specific cases where the difference is material: irregular or seasonal usage where a validity window wastes budget, small purchases where volume-tier pricing does not apply to you, work that needs ASN-level or US city-level targeting alongside sticky sessions up to twenty-four hours, anyone who wants a 4G/5G port on a real carrier modem rather than mobile IPs drawn from a metered pool, and teams that would rather buy residential, datacenter and static products from the same dashboard.

Neither of these is a verdict on quality. They are different product shapes aimed at different buying patterns, and the honest answer for a fair number of readers is to keep a PYProxy balance for the products or workflows Nefo still does not sell — the S5 client model or flat-fee unlimited plans — and run residential traffic wherever it performs better on their own targets.
