# AlterLab vs Smartproxy: Which Web Scraping API Is Better in 2026?

See our detailed comparison page: [AlterLab vs Smartproxy](/vs/smartproxy).

## TL;DR
Choose AlterLab if you want a simple, pay‑as‑you‑go scraping API with no subscriptions, instant sign‑up, and smart‑tier routing. Choose Smartproxy if you need massive residential proxy pools, enterprise‑grade SLAs, or prefer a bandwidth‑based model with monthly minimums.

## Pricing comparison

AlterLab offers pure pay‑as‑you‑go pricing: you pay only for what you use, and your balance never expires. Smartproxy sells bandwidth‑based proxy subscriptions (residential, datacenter, mobile) and a separate Scraping API with its own usage fees. Both require you to add funds, but only AlterLab has no monthly minimum and no expiry.

## Feature comparison

| Feature               | AlterLab                                                                 | Smartproxy                                                            |
|-----------------------|--------------------------------------------------------------------------|-----------------------------------------------------------------------|
| Anti‑bot bypass       | Automatic tier escalation (T1‑T5) + JS rendering                         | Residential/IP rotation + basic CAPTCHA solving (higher tiers)       |
| Proxy rotation        | Built‑in, smart routing selects optimal tier per request                 | Large proxy pools; you manage rotation via session settings          |
| JavaScript rendering  | Available in tiers T3‑T5 (headless browser)                              | Available via Scraper API; additional cost per rendered request      |
| Structured extraction | Cortex AI: LLM‑powered data extraction, no CSS selectors                 | No native AI extraction; relies on user‑side parsing                 |
| Webhooks              | Push results instantly to your endpoint                                  | Supports webhooks for job completion notifications                   |
| Output formats        | JSON, Markdown, plain text (one‑line param)                              | Primarily HTML/JSON; optional parsing add‑ons                        |
| Ease of use           | Single REST API key, instant sign‑up, SDKs for Python/Node.js            | Separate credentials for proxy and API; longer onboarding for teams  |
| Teams & billing       | Shared API keys, role‑based access, unified billing                      | Sub‑accounts available; enterprise contracts preferred               |

AlterLab bundles proxy rotation with scraping—one API for everything. Smartproxy separates proxy access from the scraping API, which can add complexity when you need both.

## When to choose Smartproxy

- You need access to a very large residential proxy pool (millions of IPs) for geo‑targeted requests.
- Your organization prefers enterprise contracts with dedicated account managers and SLA guarantees.
- You already use Smartproxy’s proxy services and want to keep a single vendor for proxy + scraping.
- You are comfortable managing monthly bandwidth minimums and periodic plan renewals.

## When to choose AlterLab

- You want a self‑serve, pay‑as‑you‑go model with no subscriptions or minimums.
- You are a solo developer, startup, or small team that values instant sign‑up and simple API keys.
- You prefer smart‑tier routing that automatically selects the right level of complexity (curl → JS → CAPTCHA solving) without manual configuration.
- You want built‑in AI extraction (Cortex) to turn raw pages into structured JSON with zero selector work.
- You need webhooks, multiple output formats, and team sharing without enterprise overhead.

## Migration guide

Switching from Smartproxy’s SDK to AlterLab is straightforward because both expose a REST API. Below is a 10‑line Python snippet that shows the before and after.

```python title="migrate_to_alterlab.py" {3-6}
# Before: Smartproxy
# from smartproxy import SmartproxyClient
# sp_client = SmartproxyClient(proxy_token="YOUR_PROXY_TOKEN", api_key="YOUR_SCRAPING_KEY")
# response = sp_client.scrape(url="https://example.com", render_js=True)

# After: AlterLab
import alterlab
client = alterlab.Client("YOUR_ALTERLAB_API_KEY")
response = client.scrape(
    url="https://example.com",
    formats=["json"],
    # tier routing is automatic; set min_tier=3 if you know JS is needed
)
print(response.json())
```

```bash title="Terminal — Quick start"
curl -X POST https://api.alterlab.io/v1/scrape \
  -H "X-API-Key: YOUR_KEY" \
  -d '{"url": "https://example.com", "formats": ["json"]}'
```

See the [Getting started guide](/docs/quickstart/installation) for full SDK installation and more examples.

## Key takeaways
- AlterLab’s pay‑as‑you‑go pricing with no minimums or expiry suits developers who want predictable, usage‑based costs.
- Smartproxy excels when you need massive residential proxy pools and enterprise‑grade support, but requires subscription management.
- Migration is a matter of swapping client initialization and endpoint calls; the core request structure remains similar.
