If you've been using MostLogin for a while, you already know the drill: a great antidetect browser is only half the equation. The other half? The proxies running underneath it.
We've tested a lot of proxy providers over the years. Some looked great on a pricing page and fell apart in production. Others had the infrastructure but made it painful to actually integrate. So when we say we recommend 9Proxy as a go-to proxy partner for MostLogin users — we mean it, and we want to explain exactly why.
First, Let's Talk About What MostLogin Users Actually Need From a Proxy
When you're running an antidetect browser, your proxy isn't just a tool — it's a core part of your identity layer. Every profile you create in MostLogin carries a fingerprint: browser environment, timezone, language, and yes, the IP it connects through.
If that IP is low quality — datacenter-looking, already flagged, or dropping mid-session — your entire profile setup falls apart no matter how clean your fingerprint is. Platforms don't just check your browser headers. They check your IP reputation, your IP consistency, and whether your geo signals make sense together.
That's the exact problem a residential proxy like 9Proxy is built to solve.
Here's Why 9Proxy Fits So Well With Mostlogin
Clean Residential IPs That Hold Up Under Profile Management
9Proxy runs a pool of 20M+ residential IPs across 90+ countries. More importantly, they prioritize IP quality over raw pool size — meaning the IPs you're getting are regularly cleaned,actively maintained, and less likely to be flagged the moment you run them through a platform with strong anti-fraud systems.
For MostLogin users managing multiple accounts on platforms like Facebook, TikTok, Amazon, or Google Ads — this is non negotiable. One blacklisted IP can cascade into a ban wave across
your entire profile set.
Geo-Targeting Down to City Level
MostLogin lets you customize timezone, language, and geolocation per profile. 9Proxy can match that at the IP level — targeting by country, state, or city depending on the location. When your browser fingerprint says "New York, EST, English (US)" and your IP actually resolves to New York — that's a coherent identity. Mismatches between fingerprint geo and IP geo are one of the most common signals that get accounts flagged.
Two Pricing Models That Fit Different Workflows
Not every MostLogin user operates the same way. Some run dozens of profiles with moderate traffic. Others scrape, automate heavily, or manage hundreds of accounts simultaneously.
9Proxy gets this, which is why they offer two distinct models:
● IP-Based (unlimited bandwidth): You buy a fixed pool of IPs and use them as much as you want. Great for steady, long-running profile automation where bandwidth isn't the bottleneck — session stability is. Pricing starts at $0.20/IP and drops to as low as $0.015/IP at volume.
● GB-Based (pay per traffic): You pay for what you actually consume. Better for workflows with variable traffic — scraping campaigns, research tasks, or anything that spikes and dips. Starting at $3.00/GB and scaling down to $0.68/GB for enterprise users.
There's also a Bundle option (IP + GB combined) for users who run mixed workflows — which honestly describes most serious MostLogin operators.
Stable Under Real Load
This is the one that doesn't show up on marketing pages but matters most in practice: how does the proxy behave when you're actually pushing volume?
9Proxy is built with B2B and scale-heavy users in mind. Their uptime sits at ~99.95%, with an average success rate of 99% and average response time of 0.6 seconds. When you're managing 50, 100, or 500 profiles simultaneously in Mostlogin, you need a proxy layer that doesn't become the bottleneck. 9Proxy holds up.
The Setup Is Straightforward
Connecting 9Proxy to MostLogin takes a few minutes. You grab your proxy credentials from the 9Proxy dashboard or app, paste them into your MostLogin profile's proxy settings, and you're done. HTTP, HTTPS, and SOCKS5 are all supported — so whatever protocol your workflow needs, it works.
If you're managing a large number of profiles, 9Proxy's Public API allows you to programmatically retrieve proxy endpoints or generate user-pass credentials and assign them dynamically — making it a strong fit with Mostlogin's profile import features for teams operating at scale.
9Proxy Pricing: What Does It Actually Cost?
Good news: 9Proxy's pricing is one of the more transparent and scalable structures we've seen. There's no "contact sales for pricing" gatekeeping until you're genuinely at enterprise volume.
Here's a full breakdown.
IP-Based Plans — Unlimited Bandwidth
You buy a fixed number of IPs and use them without any bandwidth cap. Perfect for Mostlogin users who run steady, long-term profile automation where session consistency matters more than traffic volume.
IPs | Price/IP | Total |
| 100 IPs | $0.20/IP | $20 |
| 500 IPs | $0.12/IP | $60 (save $40) |
| 1,000 + 500 bonus IPs | $0.07/IP | $105 (save $45) |
| 2,500 IPs | $0.07/IP | $175 (save $75) |
| 5,000 IPs | $0.06/IP | $300 (save $200) |
| 15,000 IPs | $0.04/IP | $600 (save $600) |
| 25,000 IPs | $0.03/IP | $750 (save $1,250) |
| 50,000 IPs | $0.025/IP | $1,250 (save $2,750) |
Enterprise IP Plans:
IPs | Price/IP | Total |
| 100,000 IPs | $0.02/IP | $2,000 (save $6K) |
| 200,000 IPs | $0.018/IP | $3,600 (save $12.4K) |
| 500,000 IPs | $0.015/IP | $7,500 (save $32.5K) |
| 500,000+ IPs | Contact sales | —— |
For context: if you're running 1,000 Mostlogin profiles and assigning one IP per profile, the 1,000+500 bonus IP plan at $105 means you're paying $0.07 per profile identity — with unlimited bandwidth on each. That's pretty hard to beat.
GB-Based Plans — Pay Per Traffic
Pay only for what you use. All regular plans come with a 180-day validity window — unused traffic doesn't expire overnight. Enterprise plans go further with unlimited validity.
Data | Price/GB | Total |
| 5GB | $3.00/GB | $15 |
| 50 GB + 5 GB bonus | $2.10/GB | $105 (save $45) |
| 100 GB | $1.50/GB | $150 (save $150) |
| 200 GB | $1.00/GB | $200 (save $400) |
| 1,000 GB | $0.80/GB | $800 (save $2.2K) |
| 2,000 GB | $0.75/GB | $1,500 (save $4.5K) |
Enterprise GB Plans — Unlimited Validity:
Data | Price/GB | Total |
| 3,000GB | $0.72/GB | $2,160 (save $6.84K) |
| 6,000GB | $0.70/GB | $4,200 (save $13.8K) |
| 10,000GB | $0.68/GB | $6,800 (save $23.2K) |
| 10,000+ GB | Contact sales | —— |
The unlimited validity on enterprise GB plans is a big deal if your team's traffic isn't consistent month-to-month. No more scrambling to "use up" bandwidth before it expires.
Bundle Plans — IP + GB Combined
The sweet spot for most Mostlogin users who need both stable profile IPs and flexible traffic for scraping or research tasks.
Includes | Price | You Save |
| 100 IPs + 5 GB | $25 | $10 |
| 1,500 IPs + 50 GB | $150 | $60 |
| 5,000 IPs + 500 GB | $600 | $250 |
All bundle plans include: 99.5% avg. success rate, 0.6s avg. response time, HTTP/SOCKS5 support, and 180-day traffic validity.
Which Plan Should Mostlogin Users Pick?
It depends on your workflow, but here's a quick cheat sheet:
● Just starting out / testing → IP Starter ($20) or GB Starter ($15)
● Running 100–500 profiles steadily → IP Most Popular (1,000+500 IPs at $105) —unlimited bandwidth is a huge advantage here
● Heavy scraping + profile management → Bundle Pro or Bundle Power● Agency or reseller scale → Enterprise IP or GB plans, or reach out to their sales team for custom pricing
9Proxy Now Has Dedicated Apps — Mobile & Desktop
This is something a lot of proxy providers still don't offer, and honestly it's a bigger deal than it sounds.
9Proxy has rolled out native apps across all major platforms:
ProxyHub Lite (iOS & Android): Connect and manage your proxies directly from your phone. No third-party app needed, no clunky workarounds. The mobile app syncs with your main dashboard, so any profile or config you set up on desktop is immediately available on mobile too. For Mostlogin users who manage accounts on mobile devices — or who just want to monitor their proxy usage on the go — this is genuinely useful.
ProxyHub Pro (Desktop): The desktop app goes a step further. Beyond just connecting to proxies, ProxyHub lets you control and configure multiple mobile devices simultaneously from a single dashboard. Think of it as a control center for your entire proxy setup — desktop and mobile, all in one place.
This is particularly powerful if you're running a mobile-heavy operation alongside your Mostlogin browser profiles. Instead of juggling multiple apps and manual configs per device, everything syncs and is managed from one interface.
And for users on Windows, there's also the Transparent Proxy Program — a system-level tool that routes all traffic through the proxy automatically, so even apps that don't have their own proxy settings work seamlessly through 9Proxy.
Bottom line: whether you're at your desk or on the move, 9Proxy has a native experience ready for you. No browser extension hacks, no third-party
The Setup Is Straightforward
Connecting 9Proxy to Mostlogin takes a few minutes. You grab your proxy credentials from the 9Proxy dashboard, paste them into your Mostlogin profile's proxy settings, and you're done. HTTP, HTTPS, and SOCKS5 are all supported — so whatever protocol your workflow needs, it works.
If you're managing a large number of profiles, 9Proxy's Public API lets you pull proxy endpoints programmatically and assign them dynamically — which pairs well with Mostlogin's profile import features for teams operating at scale.
Who Gets the Most Out of This Combo?
Honestly? Most people in our community will benefit. But here's who we think this pairing is especially powerful for:
● E-commerce & marketplace sellers running multiple seller accounts who need clean, geo-consistent IPs per profile
● Social media marketers & growth teams managing multiple ad accounts or brand profiles across Meta, TikTok, or Google
● Affiliate marketers who need to test landing pages, offers, and creatives from multiple geo locations
● MMO operators who need high-volume, stable IP infrastructure to support automation at scale
● Agencies & resellers managing client accounts who need reliable proxy infrastructure without the enterprise price tag of BrightData or Oxylabs
Our Take
We don't recommend proxy providers lightly, because a bad proxy recommendation directly hurts our users' workflows — and by extension, Mostlogin's reputation.
9Proxy made it onto our recommended list because they solve the real problems: IP quality, session stability, geo-targeting accuracy, and pricing that actually makes sense when you're operating at volume. They're not trying to be the flashiest name in the proxy space. They're trying to be the most reliable one for people who use proxies seriously.
That's exactly the kind of partner that makes sense for the Mostlogin community.
