TL;DR

Choose Bright Data if you are an enterprise data team that needs massive residential proxy pools, dedicated account managers, and pre-packaged datasets. Choose AlterLab if you are a developer or startup looking for a simple REST API, transparent pay-as-you-go pricing without monthly minimums, and automated 5-tier smart routing that handles CAPTCHAs for you.

Introduction

Finding the right web scraping API in 2026 requires balancing proxy network size, success rates, API usability, and cost. Developers often start by evaluating Bright Data due to its market presence. You might be researching a bright data alternative to reduce monthly minimum spend or simplify your data extraction pipeline.

This guide provides a factual comparison of AlterLab vs Bright Data. We evaluate their API architectures, proxy handling mechanisms, extraction capabilities, and pricing structures. The goal is to give you specific technical details to help you choose the tool that fits your architecture.

Pricing Comparison

Understanding the true cost of web scraping involves more than looking at the base rate per request. You have to factor in bandwidth costs, successful request rates, monthly minimums, and balance expiration policies.

Bright Data offers a wide range of pricing tiers based on the specific product you use. Their Web Unlocker and Scraping Browser products typically offer pay-as-you-go rates, but they heavily incentivize monthly subscriptions. These subscriptions often start around $500 per month. If you commit to higher monthly spends, your cost per request or cost per gigabyte drops significantly. Unused bandwidth or request limits at the end of the billing cycle typically do not roll over.

AlterLab takes a different approach to pricing. We offer a strict pay-as-you-go model. You fund your balance, and that balance never expires. There are no monthly subscriptions, no minimum spend requirements, and no sales calls needed to unlock higher tiers. You only pay for successful requests. If a scrape fails, it costs you nothing.

The difference in billing philosophy changes how you scale. With Bright Data pricing in 2026, scaling from a prototype to production usually involves signing a contract to secure viable rates. With AlterLab, you scale by simply making more API requests, and the cost remains predictable.

Feature Comparison

Both platforms allow you to extract HTML from target websites, but they solve anti-bot challenges differently.

Proxy Networks and Routing

Bright Data maintains one of the largest proxy networks available, including datacenter, ISP, residential, and mobile IPs. You have granular control over session persistence, geographic targeting, and IP rotation. If your architecture requires manually routing requests through a specific proxy port, Bright Data provides fine-grained control.

AlterLab abstracts proxy management entirely. We use a 5-tier smart routing system. Tier 1 handles standard curl requests for unprotected sites. If a site blocks Tier 1, the request automatically escalates to higher tiers. Tier 3 introduces JavaScript rendering. Tier 5 handles complex CAPTCHA solving. You do not manage IP rotation or select proxy types. The API determines the lowest required tier to fetch the page successfully. You can force a minimum tier using the min_tier parameter if you know a site requires JS rendering.

Anti-Bot Evasion

Bright Data's Web Unlocker handles browser fingerprinting, cookie management, and CAPTCHA solving automatically. It mimics human browsing behavior. Their Scraping Browser allows you to connect Puppeteer or Playwright scripts directly to their infrastructure, executing your browser automation commands on their servers while they handle the evasion.

AlterLab focuses on single-endpoint simplicity. You send a URL, and our infrastructure manages the evasion internally. Our auto-escalation handles standard Cloudflare, Datadome, and Akamai protections. We return the raw HTML or structured data. If you need scheduled scrapes, AlterLab provides built-in cron expression scheduling. Automate recurring scrapes directly on our platform without running a separate task queue.

Data Extraction and Formats

Bright Data offers predefined datasets for major e-commerce and social platforms. If you need historical product data from Amazon without scraping it yourself, they sell it. They also provide IDE tools to write parsing logic within their platform.

AlterLab offers flexible data formats directly from the API. You can request clean JSON, Markdown, or plain text output alongside raw HTML. Our Cortex AI feature extracts structured data using LLMs. You define a schema, and Cortex returns clean JSON without requiring fragile CSS selectors. If the page layout changes, the AI adapts automatically.

You can also use AlterLab Webhooks to push results to your server instantly. You avoid polling our API to check if a long-running scrape finished.

When to Choose Bright Data

Bright Data fits specific organizational profiles and technical requirements. Choose them if:

• You need massive IP diversity: You require millions of distinct residential IPs across hundreds of specific cities.
• You have complex browser automation scripts: You want to run extensive Playwright scripts on remote browsers via their Scraping Browser.
• You buy datasets: You prefer purchasing pre-scraped historical data rather than building your own collection pipelines.
• You have an enterprise budget: Your company is comfortable with annual contracts, dedicated account managers, and predictable large-scale monthly bandwidth billing.

When to Choose AlterLab

AlterLab is built for developers who want results without managing infrastructure. Choose us if:

• You want pay-as-you-go pricing: You refuse to pay monthly minimums or subscriptions. You want to fund your account with $20 and know that balance will still be there in six months.
• You prefer a simple REST API: You want to send a URL and get HTML back without configuring proxy chains, managing sessions, or tuning fingerprint headers.
• You need built-in scheduling: You want to run recurring scrapes using standard cron syntax directly on the scraping platform.
• You want AI-powered extraction: You want structured JSON via our Cortex AI without writing or maintaining CSS selectors.
• You prefer self-serve access: You want to create an account, grab an API key, and write your first script in two minutes without talking to sales.

Migration Guide

Migrating from Bright Data to AlterLab involves shifting from proxy configuration to REST API calls. AlterLab's Python client and REST endpoints make this straightforward. Read our Getting started guide for full documentation.

Here is a typical Python migration:

# Before: Bright Data
# import requests
# proxies = {"http": "http://user:[email protected]:22225"}
# response = requests.get("https://example.com", proxies=proxies)

# After: AlterLab
import alterlab
client = alterlab.Client("YOUR_API_KEY")
response = client.scrape("https://example.com", min_tier=3)
print(response.text)

If you prefer terminal testing, the cURL implementation is equally simple. You pass your target URL in the JSON payload.

curl -X POST https://api.alterlab.io/v1/scrape \
  -H "X-API-Key: YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"url": "https://example.com", "formats": ["html", "markdown"]}'

The AlterLab API handles the proxy rotation, session management, and any necessary CAPTCHA solving behind the scenes. You receive the parsed response directly.
