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

See the detailed comparison page [here](/vs/scrapfly).

## TL;DR
Choose AlterLab if you want a pay‑as‑you‑go API with no subscription, balance that never expires, and a simple REST interface. Choose ScrapFly if you need a large proxy pool, enterprise‑grade SLAs, or prefer committing to a monthly credit plan.

## Pricing comparison
AlterLab’s pricing is purely consumption based. You add funds to a balance and spend per successful request. There are no monthly minimums and the balance does not expire.

ScrapFly sells monthly plans that include a set number of API call credits. Unused credits typically do not roll over, and you must renew each month to continue scraping.

| Feature               | AlterLab                     | ScrapFly (as of 2026)               |
|-----------------------|------------------------------|--------------------------------------|
| Pricing model         | Pay‑as‑you‑go                | Monthly subscription with credits    |
| Minimum spend         | None                         | Monthly plan required                |
| Balance expiry        | Never                        | Credits reset monthly                |
| Starting cost         | $0.0002 per request          | $29/month for 100k credits (example) |
| Over‑run handling     | Pay per extra request        | Upgrade plan or buy add‑on pack      |

## Feature comparison
Both platforms handle the heavy lifting of proxy rotation, JavaScript rendering, and anti‑bot measures. Differences appear in breadth and ease of use.

**Anti‑bot bypass & proxy rotation**  
AlterLab uses a five‑tier smart routing system that automatically escalates from simple HTTP requests to full browser rendering with captcha solving when needed. ScrapFly maintains a large residential proxy pool and offers similar tiered rendering, but their documentation emphasizes manual tier selection.

**JavaScript rendering**  
Both provide headless browsers for JS‑heavy sites. AlterLab’s rendering is invoked implicitly when a lower tier fails; ScrapFly exposes explicit rendering parameters.

**Structured data extraction**  
AlterLab includes Cortex AI, an LLM‑powered extractor that returns JSON without CSS selectors. ScrapFly offers a scraping API with optional data parsing via HTML selectors or third‑party integrations.

**Ease of use**  
AlterLab’s API is a single endpoint with JSON payloads. ScrapFly’s API is also RESTful but requires managing credit balances and plan upgrades through a dashboard.

- **$0.0002** — Per Request (from)
- **5 tiers** — Smart Routing
- **0** — Monthly Minimum

## When to choose ScrapFly
- Your team requires a dedicated account manager and custom SLA.
- You need access to a proprietary proxy network with millions of IPs.
- You prefer predictable monthly billing and are comfortable estimating credit usage.
- You want built‑in integrations with specific data‑storage or monitoring tools ScrapFly offers via partnerships.

## When to choose AlterLab
- You are a solo developer, startup, or small team that values zero‑commitment pricing.
- You want to start scraping immediately after sign‑up with no sales call.
- You dislike worrying about monthly minimums or expiring credits.
- You prefer a straightforward API that you can test with a single curl request.
- You need automatic tier escalation so you never have to manually adjust rendering depth.

## Migration guide
Switching from ScrapFly to AlterLab involves updating the client initialization and request format. Below are equivalent snippets in Python and cURL.

```python title="migrate_to_alterlab.py" {3-6}
# Before: ScrapFly
# scrapfly_client.scrape(url, ...)

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

```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"}'
```
