Is AlterLab a good ZenRows alternative?

Yes. AlterLab matches ZenRows on protected site handling, JavaScript rendering, and geo-targeting — but adds smart tier routing that automatically selects the cheapest approach per URL. For teams paying $49–$249/month on ZenRows, switching to AlterLab's pay-as-you-go model typically cuts costs by 60–78% on mixed workloads. Balance never expires, so there's no pressure to 'use up' credits before month-end.

How does AlterLab pricing compare to ZenRows?

ZenRows charges a flat ~$0.0009/request for basic pages and ~$0.0030/request for JavaScript-rendered pages. AlterLab starts at $0.0002/request (Tier 1, no JS) and goes up to $0.004/request only for the heaviest rendering tier (Tier 4). Most mixed workloads average $0.0003–$0.0006/request with AlterLab's automatic tier routing — 33–78% cheaper than ZenRows depending on your URL mix.

Can I migrate from ZenRows to AlterLab in a few minutes?

Yes. The main change is switching from ZenRows' GET query-string API to AlterLab's POST JSON API. Replace the endpoint, move your API key to the X-API-Key header, and send URL in the JSON body. Most teams complete migration in under 10 minutes. The 5,000-request free tier lets you test your full URL mix before committing any spend.

Does AlterLab handle protected sites like ZenRows?

Yes. AlterLab's Tier 3 and Tier 4 handle enterprise-grade bot-detection systems — the same coverage as ZenRows. The key difference is that AlterLab only uses expensive rendering when actually needed: Tier 1 handles the 60–70% of pages that don't require it, keeping average cost well below ZenRows' flat rate.

What happens to my AlterLab balance if I don't use it?

Your balance never expires. ZenRows resets monthly — unused credits are lost at the end of every billing period. AlterLab keeps your balance indefinitely, making it the better choice for projects with irregular scraping demand, seasonal workloads, or development phases where volume varies month to month.

Common frustrations

Why developers leave ZenRows

Real pain points from developers who switched to AlterLab

Paying Full Price for Simple Pages

ZenRows charges the same rate whether you're hitting a static blog or a complex protected e-commerce site. With AlterLab's tier routing, simple pages use Tier 1 ($0.0002) and only escalate to heavier tiers when actually needed — automatically.

Monthly Subscriptions for Irregular Use

Scraping demand isn't constant. ZenRows' subscription model means you pay $49–$249/month even during quiet periods. AlterLab charges per request with balance that never expires — perfect for projects with variable volume.

No Structured Output Without Extra Work

ZenRows returns raw HTML — you parse it yourself. AlterLab extracts structured JSON and Markdown natively, making it the better choice for AI pipelines and data pipelines that need clean output without custom parsers.

No Auto-Escalation on Failures

When ZenRows fails on a protected page, you retry manually at higher cost. AlterLab automatically escalates through tiers on failure — so your pipeline keeps running without engineering intervention.

Migration Steps

Code Migration Example

Before (ZenRows)

Python

# ZenRows: GET with query parameters
curl "https://api.zenrows.com/v1/?apikey=YOUR_KEY&url=https://example.com&js_render=true"

After (AlterLab)

Python

# AlterLab: POST with JSON body
curl -X POST https://api.alterlab.io/api/v1/scrape \

  -d '{"url": "https://example.com", "formats": ["html"]}'

Compatibility Notes

•AlterLab uses POST JSON vs ZenRows' GET query-string — update your HTTP client accordingly
•Authentication: use X-API-Key header instead of the apikey query parameter
•JS rendering is automatic in Tier 2+ — no separate js_render=true flag needed
•All response formats (HTML, Markdown, JSON) are natively supported
