In-Depth Pricing Comparison of Anti-Detect Browsers for Web Scrapers

Comparing features and prices of the most well-known anti-detect browsers on the market

As a professional web scraper, you know that your tools must be as flexible and robust as your projects demand. Originally designed for multi-account management, anti-detect browsers have evolved rapidly. Today, they’re an essential asset for web scraping, where performance and scalability are paramount. This article delves into how pricing models have adapted to the needs of web scrapers and provides a detailed comparison to help you choose the best solution for your next large-scale project.

Key Technical Insights

Before diving into vendor comparisons, let’s clarify some key operational terms that underpin anti-detect browser pricing and functionality. This may be more detail than advanced web scrapers need, but it's essential for beginners to understand.

Requests Per Minute (RPM) and Requests Per Hour (RPH)

• RPM (Requests Per Minute): This refers to the number of API calls your automation script can make within one minute. When using an anti-detect browser for web scraping, actions such as generating a new fingerprint or launching a browser session are counted towards your RPM quota. .

• RPH (Requests Per Hour): Beyond the per-minute limits, many anti-detect browser services also set an hourly cap. For example, a plan might offer 100 RPM while limiting the total to 1500 RPH. This means if you operate at full gas (100 RPM) for an hour, you would theoretically need 6000 requests per hour, forcing you to pace your scraping tasks or incur extra costs for additional requests.

Parallel Automated Browsers

For serious scraping operations, running multiple browsers in parallel is non-negotiable. Whether you’re collecting price data from e-commerce sites or monitoring stock changes, the ability to run dozens—or even hundreds—of automated sessions concurrently is critical, both for faster data access and for meeting the real-time demands of multiple users simultaneously. Terms like “Parallel Automated Browsers” or “Browserless Concurrency” refer to this very capability.

A Real-World Web Scraping Scenario

Imagine you’re tasked with scraping pricing and availability data from a major e-commerce platform. Your goal is to collect up-to-date product information across thousands of listings, which means you need to run multiple browser sessions concurrently to stay ahead of rapid changes.

In this scenario, you plan to launch 50 automated browsers simultaneously. Each browser session is set to run for about 30 seconds to complete its task—this might include crafting and launching a unique browser profile (with its own fingerprint), navigating to the product page, and scraping key data points. Typically, initiating a browser session involves 2–3 API calls (one for profile creation, one for launching, and possibly another for an initial activity). This adds up to roughly 200 API calls per minute.

For many anti-detect browsers, such a request rate can quickly exceed the available RPM and RPH limits, unless you choose a vendor that offers either unlimited or significantly high caps. This realistic example underscores the importance of aligning your chosen service with your project’s specific demands.

In-Depth Anti-detect Browser Pricing Analysis

Below is a detailed comparison of several popular anti-detect browsers, focusing on their pricing models, API request limits, and concurrency features. All pricing information is based on publicly available data as of March 5th, and all costs have been standardized to comparable monthly subscription levels.

Kameleo

• Pricing & Plans:
  Kameleo offers two tailored packages— “START” and “SCALE”—designed with the web scraper’s workflow in mind. With the START plan beginning at just €29 (or €21/month when billed annually), you can launch two concurrent browsers as a starting point.

• Real-World Example:
  For our example (50 concurrent sessions, 30-second runtime, 200 RPM), the SCALE package would be the appropriate choice, costing €279 per month. Kameleo stands out by offering unlimited RPM and RPH along with robust server support, so you can scale your scraping operations seamlessly. If more parallel sessions are needed, you can easily add additional browser slots in increments (e.g., 10 extra browsers for an additional €20).

OctoBrowser

• Pricing & Plans:
  OctoBrowser’s Advanced package is positioned for high-performance needs, with the example use case priced at €329 per month.

• Key Consideration:
  However, its hourly API request cap (RPH) is set at 3000. This limit effectively restricts the RPM to about 50—far below the 200 RPM needed for our scenario. Although you can purchase extra RPM, doing so will add to your overall cost, making it less attractive for high-frequency scraping projects.

Multilogin

• Pricing & Plans:
  Multilogin’s Team package is offered at €159 per month, and it includes a 100 RPM limit.

• Key Consideration:
  Despite the competitive price, the package provides only a 100 RPM limit, which is insufficient for scenarios requiring 200 RPM. This necessitates reaching out for custom pricing to accommodate higher limits, with no clear public pricing details available.

Incognition

• Pricing & Plans:
  Incognition’s pricing information is less transparent regarding RPM, RPH, or concurrent browser capabilities.

• Key Consideration:
  Their model appears to focus on factors such as the number of browser profiles and team members rather than directly on API call limits. This might work well for some use cases, but it requires further clarification directly from their support team.

Undetectable.io

• Pricing & Plans:
  Similar to Incognition, Undetectable.io does not publicly specify detailed metrics like RPM or parallel automated browser limits.

• Key Consideration:
  Their pricing is primarily based on the number of cloud profiles and user accounts. Potential users will likely need to contact their support for precise details tailored to heavy web scraping operations.

NST Browser

• Pricing & Plans:
  Designed with the needs of web scrapers in mind, NST Browser offers a competitive Enterprise plan at $59.9 per month (approximately €55/month). This plan provides up to 100 concurrent browsers— the lower-tier plan allows only 30 sessions.

• Key Consideration:
  One important aspect is the “Browser Usage Time” limit, which is capped at 2500 hours per month. When divided by an average of 720 hours per month, this allows for roughly 3.5 profiles per hour—a limitation that may require additional hour purchases for lengthy scraping operations.

Final Thoughts

For the discerning web scraper, choosing the right anti-detect browser hinges on more than just the base price - it requires a careful balance between API request limits, parallel running automated browsers, and overall scalability.

• Kameleo leads in flexibility with unlimited RPM/RPH and the ability to easily add concurrent browser sessions, making it highly suited for intensive, large-scale scraping tasks.

• OctoBrowser: OctoBrowser is ideal for complex scraping tasks. While its API request rate cap may require additional investment for extremely high call volumes, its overall performance and advanced functionality make it a strong contender.

• Multilogin: Multilogin provides a competitive RPM limit and reliable performance. While scenarios requiring higher limits might call for custom solutions, its flexibility and ease of integration are major advantages.

• Incognition and Undetectable.io offer interesting alternatives, but it's a good idea to check with their support teams for more details before choosing a plan.

• NST Browser: Particularly appealing for projects that can operate within its usage time constraints, NST Browser is a great option for scrapers willing to scale with additional hour purchases. Its design is optimized for web scraping, ensuring high performance even for demanding projects.
