A proxy browser routes your web traffic through a remote server, so sites see the proxy's IP address instead of yours. It's the tool you reach for when you need a different IP per session — scraping, managing multiple accounts, or reaching geo-blocked content. The term covers two very different things: lightweight web-based proxy services you use inside a normal browser, and full anti-detect browsers built for automation and fingerprint isolation.
Key takeaways
- A proxy browser hides your IP by routing traffic through a proxy server; anti-detect browsers add per-profile fingerprint isolation.
- Web-based proxy services work inside any browser but often break on JavaScript-heavy sites and offer no automation.
- Desktop anti-detect browsers like Multilogin, AdsPower, and Dolphin Anty are the standard for account management and scraping.
- Automation support matters most — look for Playwright, Puppeteer, Selenium, or CDP compatibility.
- Cloud proxy browsers like Send.win shift profiles online, removing local resource limits.
What is a proxy browser?
A proxy browser is a web client that sends its traffic through an intermediary proxy server, so the destination website sees the proxy's IP address rather than your real one. The term covers two distinct tools: browser extensions or web pages that proxy individual requests, and dedicated anti-detect browsers that combine proxying with per-profile isolation.
The first type — a web-based proxy — is what most people mean when they search "proxy browser online." You paste a URL into a page, and that page fetches it for you, returning the content through a different IP. It's simple and requires no installation, but it's brittle: many modern sites block known proxy IP ranges, and interactive features like login flows often fail.
The second type is a purpose-built browser. These are Chromium-based applications (or cloud-hosted versions) that let you create isolated profiles, each with its own IP, cookies, canvas fingerprint, and user agent. They're the workhorses of affiliate marketing, social media management, and web scraping.
How does a proxy browser work?
Every request your browser makes travels from your device to the proxy server, which forwards it to the target site with the proxy's IP as the sender. The site's response comes back through the same path, so your real IP is never exposed. On top of that layer, anti-detect browsers create a separate browsing context per profile — each with its own storage, cache, and fingerprint.
That fingerprint isolation is what separates a proxy browser from simply setting a proxy in Chrome's settings. When you open a regular browser with a proxy, every tab shares one identity: same canvas hash, same user agent, same timezone. Websites can link those tabs even if you rotate IPs. An anti-detect browser forces each profile to look like a different physical device, which is why it's the standard for running multiple accounts without getting flagged.
Pro tip: If you only need to hide your IP for a quick visit, a free web proxy is fine. If you plan to manage more than two accounts on the same site, you need a fingerprint-isolated browser, not just a proxy.
Web-based proxy vs. desktop anti-detect browsers
The simplest proxy browser is a website you visit, like a translation service or an anonymizer. You type in a URL, and it fetches the page for you. These are free, require zero setup, and work in any browser. Their shortcomings are real: no automation support, no cookie persistence beyond the page, and a high chance of CAPTCHA walls because proxy IPs are widely blacklisted.
Desktop anti-detect browsers sit at the opposite end. You install software, create profiles, assign a proxy to each, and launch them like separate browser windows. They give you full control over proxy rotation, cookies, and automation. The cost is complexity and a learning curve.
Here's the quick comparison:
| Feature | Web-based proxy | Anti-detect browser |
|---|---|---|
| Installation | None | Desktop app or cloud |
| IP masking | Yes | Yes |
| Fingerprint isolation | No | Yes |
| Automation | None | Playwright/Puppeteer/Selenium |
| Cookie persistence | Per page only | Per profile |
| Cost | Free to low | $9–$30/month |
| Best for | Casual privacy | Account management, scraping |
If your query is "web based proxy" or "proxy web browser online," you're probably looking for the first type. If you searched "best proxy browser for automation," you want the second.
Best proxy browsers for automation
Automation is where proxy browsers earn their keep. Scraping, social media scheduling, and ad verification all need a browser that can run scripts while keeping each session isolated. Here are the leading options.
Multilogin is the oldest anti-detect browser and still a reference point. It offers no free plan, a 3-day trial for $2, and paid plans starting at $9/month. It supports Puppeteer and Selenium automation and holds a 4.8/5 G2 rating from 98 reviews.
AdsPower has a free plan with 2 profiles and paid plans from about $9/month for 10 profiles. It includes built-in RPA automation and a local REST API compatible with Selenium, Playwright, and Puppeteer — a strong choice for developers who want to script everything.
Dolphin Anty offers a free tier with 5 profiles (some sources say 10) and paid plans starting at $10/month. It's popular for affiliate marketing and supports automation through its API.
GoLogin provides a free plan with 3 profiles and paid plans from about $24/month. Its cloud-based profile storage means you can launch the same profiles from any device, which is handy for remote teams.
Octo Browser has no free desktop plan; it costs €10/month for 3 profiles. It supports Playwright, Puppeteer, Selenium, and CDP, and offers one-time profiles that disappear after closing — useful for short scraping sessions.
Nstbrowser offers unlimited profiles on paid plans starting around $9/month, with tight Puppeteer and Playwright integration out of the box and bulk CSV or paste proxy import. It's a newer entrant that appeals to scrapers.
Send.win is a cloud-based proxy browser. Instead of a desktop app, profiles live in the cloud and you connect from a lightweight client. It includes automatic proxy rotation, health checking with failover, per-profile fingerprint isolation, and scaling to 100+ sessions without eating your local RAM.
Note: For scraping, look for one-time profiles (Octo) or cloud scaling (Send.win) so you don't leave stale cookies that get traced back to your operation.
How much do proxy browsers cost?
Prices cluster tightly: entry-level paid plans run $9–$25/month, and most tools offer a small free tier to test with. The table below shows current published pricing as of mid-2026.
| Browser | Free tier | Entry price | Automation | Architecture |
|---|---|---|---|---|
| Multilogin | None (3-day trial $2) | ~$9/month | Puppeteer, Selenium | Desktop |
| AdsPower | 2 profiles | ~$9/month (10 profiles) | REST API, Selenium, Playwright | Desktop |
| Dolphin Anty | 5–10 profiles | ~$10/month | API | Desktop |
| Nstbrowser | None | ~$9/month (unlimited profiles) | Puppeteer, Playwright | Desktop |
| GoLogin | 3 profiles | ~$24/month | API | Desktop + cloud |
| Octo Browser | None | €10/month (3 profiles) | Playwright, Selenium, CDP | Desktop |
| Send.win | 30-day trial | $9.99/month (150 profiles) | Automation API | Cloud |
The free tiers are genuinely small — 2 to 10 profiles — so they're for testing, not production. If you need more than a handful of persistent profiles, budget for a paid plan.
Separate from the browser, you'll pay for proxies themselves. Residential rotating proxies run $5–$15/GB with 85–95% success rates; ISP static residential costs $15–$30/GB with 90–97% success; mobile proxies run $20–$50/GB with 95–99% success. Another guide lists datacenter proxies at $0.50–$2/GB but warns of 40–60% success on protected sites. The browser fee and proxy fee are two different bills.
Which proxy browser should you choose?
Pick by workload, not by brand loyalty.
For casual privacy — reaching a geo-blocked page once — a free web-based proxy is enough. You don't need an anti-detect browser.
For running a few social accounts (3–10 profiles), AdsPower's free tier or Dolphin Anty's free tier gets you started at $0. When you scale past the free limit, the $9–$10/month entry plans are fine.
For heavy scraping with lots of short-lived sessions, Octo Browser's one-time profiles or Send.win's cloud scaling are the best fits. Octo keeps everything local; Send.win offloads the work to the cloud if you're running 50+ concurrent sessions.
For development and scripted automation, choose a browser with first-class Playwright or Puppeteer support. AdsPower, Nstbrowser, and Octo all expose clean APIs. Multilogin works too but its entry price and no-free-tier status make it a bigger commitment.
For team collaboration, GoLogin's cloud profile storage or Send.win's cloud architecture lets multiple people share profiles without shipping config files.
Warning: Don't assume a free proxy browser keeps you anonymous. Free public proxies are often monitored or injected with ads. If your task involves sensitive data, spend the $10/month on a reputable service.
Limitations
A proxy browser is not a magic cloak. Social platforms and scraping targets actively detect proxy IP ranges — residential proxies have success rates of 85–95%, meaning 5–15% of requests fail. JavaScript-heavy sites may fingerprint your browser even with a proxy.
The free tiers are too small for serious use, and some sources disagree on exact pricing (Multilogin's entry price is listed as both $9/month and $99/month depending on the comparison site). Workloads that need thousands of profiles will cost hundreds of dollars monthly.
If your goal is pure anonymity against advanced threats, a proxy browser is the wrong tool — that's a job for Tor or a VPN with a kill switch. And if you're just trying to access one blocked site, a VPN or a website-specific proxy is faster than setting up an anti-detect browser.
Frequently asked questions
Can I use a proxy browser for free?
Yes — most anti-detect browsers offer a free tier with 2–10 profiles, and free web-based proxies exist, but free plans are for testing, not production. Free proxies are also commonly unreliable or insecure.
What's the difference between a proxy and a VPN?
A proxy only forwards web traffic and doesn't encrypt it, while a VPN encrypts all traffic between your device and the server. For per-account isolation, proxies are lighter; for full-system privacy, a VPN is stronger.
Do proxy browsers work for all websites?
No. Many sites detect and block known proxy IP ranges, and sites with strict bot detection (like Google) will still show CAPTCHAs. You may need a residential or mobile proxy to get accepted.
How do I set up a proxy in regular Chrome?
You can add a proxy through Chrome's command-line flags, but it applies to all tabs and gives you no fingerprint isolation. For account separation, a dedicated proxy browser is the better path.
Is a proxy browser legal?
Generally yes, but terms of service matter. Using proxies to scrape data or manage multiple accounts may violate a site's ToS and could lead to bans. Always check the site's rules and local laws.
Next step: test before you commit
Start with the free tier of two or three browsers — AdsPower and Dolphin Anty are easy entry points — and run your actual workload for a week. Check success rates, CAPTCHA frequency, and how hard the automation API is to work with. Only then decide which subscription to buy.
If your job needs 50+ concurrent sessions, skip the desktop apps and try Send.win's 30-day trial to see whether cloud scaling genuinely removes the headache. Either way, the tool is only as good as the proxies you feed it — budget for those separately.
Manage multiple accounts from one browser
Sendwin is a native cloud browser that lets you log into multiple accounts on the same site simultaneously.
