AlterLab vs Zyte: In-Depth Review with Benchmarks & Product Suite Analysis

TL;DR

AlterLab is ideal for developers seeking a simple, pay-as-you-go scraping API with no subscription fees and balance that never expires. Zyte suits enterprise teams needing large proxy pools and advanced features, but requires navigating commitment-based pricing. Choose AlterLab for self-serve simplicity; choose Zyte for enterprise-scale dedicated support.

For a detailed feature-by-feature breakdown, see our AlterLab vs Zyte comparison page.

Pricing comparison

AlterLab uses a pure pay-as-you-go model: you purchase a balance that never expires and pay only for successful requests. Zyte offers credit packs and enterprise contracts, often with monthly minimums and balance resets.

As of 2026 public pricing:

• AlterLab: Starts at $0.0002/request for Tier 1 (basic HTML). No subscription, no minimums. See full pricing
• Zyte: Credit packs begin at $25 for 20,000 requests ($0.00125/request). Enterprise plans require annual commitments. Balance resets monthly if unused.

Feature comparison

Both platforms handle core scraping needs, but differ in approach and complexity.

AlterLab strengths:

• 5-tier smart routing (T1-T5) automatically escalates based on site difficulty
• Simple REST API with official Python/Node.js SDKs
• Instant sign-up, no sales call required
• Built-in proxy rotation and JavaScript rendering across all tiers

Zyte strengths:

• Larger proprietary proxy pool (particularly for geo-targeted requests)
• Advanced session management for complex login flows
• Dedicated account management for enterprise tiers
• Longer history in the enterprise scraping market

Both offer:

• Automatic anti-bot bypass (Cloudflare, Akamai, etc.)
• Structured data extraction options
• Webhook support for result delivery
• Usage monitoring and analytics dashboards

When to choose Zyte

Consider Zyte if you:

• Require guaranteed SLA-backed uptime for mission-critical pipelines
• Need access to specialized proxy types (residential, mobile) at massive scale
• Prefer negotiating custom enterprise contracts with dedicated support
• Are already integrated into Zyte's ecosystem (e.g., using their Crawlera or Smartproxy products)

When to choose AlterLab

Choose AlterLab if you:

• Are a solo developer, startup, or small team wanting predictable, usage-based costs
• Value immediate access without sales calls or minimum commitments
• Prefer a gentle learning curve with clear documentation and SDK examples
• Want your balance to roll over indefinitely (no use-it-or-lose-it pressure)
• Need straightforward JSON/Markdown/Text output formats without extra configuration

Migration guide

Switching from Zyte to AlterLab takes minutes. Both offer similar REST endpoints and SDK structures. Below is a minimal migration example showing equivalent scrape requests.

# Before: Zyte (using official SDK)
# from zyte_project import Client
# zyte_client = Client(api_key="YOUR_ZYTE_KEY")
# response = zyte_client.get(url="https://example.com", http_response_body=True)

# After: AlterLab
import alterlab
client = alterlab.Client("YOUR_ALTERLAB_KEY")
response = client.scrape(
    url="https://example.com",
    formats=["json"]  # Optional: get parsed JSON instead of raw HTML
)
print(response.json if response.format == "json" else response.text)

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