What Mars Proxies is built around
Mars Proxies is a self-serve, multi-product proxy house rather than a specialist. It sells four distinct product lines from one dashboard, and its published material is unusually explicit about retail drops: there are dedicated pages for sneaker proxies and named retailers, plus a blog section on sneaker bots. That heritage shapes the whole catalogue — static IPs with unlimited bandwidth and unlimited concurrent sessions are exactly what a checkout workload needs, and that is what Mars Proxies leads with.
The commercial model is deliberately low-friction. Residential traffic is sold per gigabyte with no expiry and no commitment, ISP and datacenter proxies are sold per IP for fixed durations, and mobile is rented per day with unlimited data. There are no contracts or order minimums on any line, and you can buy a single ISP proxy. Mars Proxies also ships consumer-facing tooling that most data-collection providers do not bother with: browser extensions and Android and iOS proxy apps.
None of that is a weakness. If you are running retail drops, managing many social accounts on fixed identities, or want one vendor covering every proxy type, Mars Proxies is a coherent, well-documented choice and the rest of this page will not persuade you otherwise.
- Residential — per GB, non-expiring, no minimum commitment
- ISP — static, dedicated IPs on unlimited bandwidth, sold per IP per duration
- Datacenter — per proxy, unlimited bandwidth, including IPv6
- Mobile — 5G/4G/LTE, rented per day with unlimited data
- Consumer tooling — browser extension, Android and iOS apps
What Nefo does not sell compared with Mars Proxies
It is worth clearing this up before any comparison. Nefo now sells residential proxies as prepaid bandwidth, 4G/5G mobile ports on real carrier modems, rented by duration, datacenter proxies, static IP proxies, IP Vault kept residential or mobile IPs, servers, and marketplace APIs. It also sells static residential ISP IPs: dedicated, in 24 countries, rented for 7 to 360 days. The difference from Mars Proxies is traffic: Nefo's ISP IPs have a 100 GB per IP per 30 days fair-use limit rather than unlimited bandwidth, so unmetered static ISP workloads may still fit Mars Proxies better.
Two honest gaps. Mars Proxies advertises sticky residential sessions up to seven days; Nefo caps sticky sessions at 24 hours. And Mars Proxies markets mobile coverage across a very wide set of locations, whereas Nefo's mobile tiers are narrower — the entry tier is United States only, and the wider tiers cover roughly six to ten countries. For long-lived residential sessions or broad international mobile coverage, Mars Proxies is the better structural fit.
Mars Proxies vs Nefo residential targeting and sessions
On the surface the two residential offers look alike: per-gigabyte billing, non-expiring traffic, HTTP/HTTPS and SOCKS5, rotating and sticky modes, username and password or IP allowlist authentication. That similarity is real, and it is why migration is cheap. The difference is in how precisely you can aim a credential.
Nefo exposes ASN and ISP targeting — you pair a country with a specific network operator, such as a particular cable, fibre or mobile carrier, and traffic exits on that operator's addresses. Mars Proxies documents its residential targeting at country and city level. If your work involves checking how a page renders to subscribers of one named carrier, verifying carrier-specific ad delivery, or reproducing a complaint that only appears on one ISP, that extra axis is the reason to look elsewhere. If country or city is enough, it is not.
The second divergence is geographic granularity. Nefo targets state or region and city directly in most countries. Residential rotation is per request; sticky credentials hold an IP from one minute to 24 hours and the duration is set per credential rather than globally.
- 227 countries on Nefo residential, with state and city targeting in most of them
- ASN/ISP targeting paired with a country
- Rotating (new IP per request) or sticky (1 minute to 24 hours)
- HTTP, HTTPS and SOCKS5, username/password or IP allowlist authenticated
- Prepaid from 5GB, non-expiring on flexible plans, credential generation free
Mobile proxies: Mars Proxies daily plans vs Nefo ports
Both providers rent mobile by time rather than by gigabyte, but the unit differs. Mars Proxies sells duration plans with unlimited data and an optional automatic rotation cadence, across a wide location list. Nefo sells a port on a real carrier modem: one live 4G/5G IP assigned to that port, which you keep or change on demand, with United States state-level and carrier-level targeting and an explicit speed tier attached to the plan (10 Mbps on the lower tiers, 20 Mbps on the faster one). Rental runs from hours up to 30 days.
The practical trade is throughput against control and specificity. Unlimited data with no stated speed ceiling suits heavy transfer; a port with a named carrier, a named US state and on-demand IP change suits work where you need to know exactly which mobile network you are exiting on and when the IP moved. Pick on which of those two properties your workload actually depends.
How to migrate from Mars Proxies to Nefo
Because the residential billing shapes match — prepaid gigabytes, no expiry, no minimum — you never have to choose between them on a calendar deadline. Bandwidth already bought from Mars Proxies does not expire, so the sensible approach is to leave it in place and run a parallel test rather than cutting over.
Integration work is small. Both support username and password authentication over HTTP, HTTPS or SOCKS5, so in most codebases the change is a host, port and credential string. What does need attention is the targeting syntax: Nefo credentials are generated in the dashboard with country, state, city, ASN and session type chosen up front, rather than being encoded ad hoc in a username by every caller. Generating credentials costs nothing, so create one per job and keep the usage attributable.
Budget a realistic sample for the comparison. 5GB is enough to confirm that the sites you care about behave the same, that your sticky sessions survive your longest multi-step flow, and that any need to keep one address is better served by Mars Proxies' static ISP line or by Nefo's static residential ISP, static IP and IP Vault options.
- Keep the existing Mars Proxies balance — non-expiring traffic does not force a cutover
- Generate a Nefo credential per job, with targeting and session type fixed at creation
- Swap host, port and credentials; protocol and auth model are unchanged
- Re-test any flow that relied on sticky sessions longer than 24 hours
- Confirm ASN or state targeting resolves correctly before moving production volume
Who should stay with Mars Proxies and who should switch
Stay with Mars Proxies if you buy static ISP IPs on unlimited bandwidth, if retail drops and checkout automation are your core workload, if you need residential sticky sessions measured in days, if you want mobile coverage across a long list of countries with unlimited data, or if browser extensions and mobile proxy apps matter to your team.
Consider Nefo if residential data collection is the workload rather than a side product, if you need ASN or ISP targeting alongside country, state and city, if you want mobile ports on real carrier modems with carrier-level targeting and on-demand IP change, or if you want to start with the smallest order, 5GB, and keep unused bandwidth indefinitely while you evaluate. Nefo's network reaches 227 countries, 22,417 cities and 14,252 ISPs; it publishes no uptime or response-time figure, because it measures neither.
Whichever you choose, the use has to stand on its own. Nefo's acceptable use policy prohibits spam, credential stuffing, payment fraud, phishing, malware distribution, network attacks and unauthorised access, and accounts that breach it are suspended. The intended workloads are price and availability monitoring, ad verification, localised SEO and search monitoring, market research, brand protection, and lawful collection of public data within site terms.
Frequently asked questions
Yes. Nefo sells static residential ISP IPs (dedicated, 24 countries, rented for 7 to 360 days from $1.76 for 7 days; see ISP proxies), datacenter proxies, static IP proxies and IP Vault kept-address products. Mars Proxies sells static ISP IPs on unlimited bandwidth, while Nefo applies a 100 GB per IP per 30 days fair-use limit.
24 hours. Sticky duration is configurable from 1 minute to 24 hours per credential. For flows that need one IP for several days, you can re-authenticate on a 24-hour cycle, use a 4G/5G mobile port where you keep the IP until you change it, or stay with a static product.
No. Prepaid balances are not transferable between providers. Both sell non-expiring residential traffic, so leave the Mars Proxies balance where it is, buy a small Nefo plan from 5 GB and run both in parallel. Nothing expires while you decide.
Usually just a host, port and credential string, since both use username and password over HTTP, HTTPS or SOCKS5. The difference is that Nefo credentials carry targeting and session type from creation, so you generate one credential per job instead of building flags into a username at call time.
For country and city work, yes. Nefo covers 227 countries, targets state or region and city in most countries. It adds ASN and ISP targeting paired with a country, which pins traffic to a named operator.
It is not positioned for it. Mars Proxies publishes retailer-specific guidance and sells static ISP IPs with unlimited bandwidth. Nefo is built for lawful data collection and use must follow site terms, applicable law and the acceptable use policy.
