ScrapFly Alternativeの代わり

Bright Data and ScrapFly take different approaches to web data collection. ScrapFly is a credit-based scraping API: one endpoint (asp=true) handles proxy rotation, JS rendering, and anti-bot bypass for any public URL, backed by strong certifications (SOC 2 Type II, ISO 27001, HIPAA, GDPR) and a generous free tier (1,000 credits, no card, no expiry). It's a solid option for developers who want a single API to call.

Bright Data offers 150M+ residential proxy IPs sold directly (not just bundled into an API), 120+ pre-built structured scraper APIs for specific sites (Amazon, LinkedIn, Google, and more), a dataset marketplace, dedicated ISP proxies, and a browser-based Web IDE. Choose ScrapFly for a single generic scraping endpoint; choose Bright Data when you need proxy infrastructure you control directly, structured per-site data, and pre-collected datasets in one platform.

ScrapFly charges variable credits per request: 1 credit for a basic HTTP scrape on a datacenter IP, +5 for JS rendering or anti-bot bypass, +25 for residential proxies, and 60 for a full-page screenshot. Plans run $30/mo (200K credits) up to $500/mo (5.5M credits), with pay-as-you-go overflow on Pro and above. Credits do not roll over month-to-month, and there are no annual plans. Independent Scrapeway benchmarks (Aug 2026) put ScrapFly's average cost at $4.9 per 1,000 requests—above the $2.7 industry average—alongside a leading 98% success rate.

Bright Data's pricing avoids this stacked-multiplier structure, so you're not charged 25-60x more just for using residential IPs or capturing a screenshot within the same request. For high-volume, JS-heavy, or residential-proxy-dependent workloads, this typically makes costs far more predictable at scale.

ScrapFly does not sell proxies as a standalone product or publish its total IP pool size. Residential and datacenter proxies (190+ countries) exist only to serve its own Web Scraping API calls, with residential requests costing 25 credits vs 1 credit for datacenter.

Bright Data operates the world's largest proxy network: 150M+ residential IPs, 1.3M+ datacenter IPs, 1.3M+ dedicated ISP IPs, and 7M+ mobile IPs across 195 countries—all available as standalone, fully configurable proxy products. If you need direct proxy access for custom tooling outside an API wrapper, Bright Data is purpose-built for that; ScrapFly's proxies exist solely to power its own API pipeline.

ScrapFly's free tier (1,000 credits, no card) and $30/mo entry plan are attractive for prototyping. But costs scale non-linearly: a residential-proxy + JS-rendering request can cost 30 credits, meaning the $30/mo Discovery plan may cover as few as ~6,600 fully-loaded scrapes rather than 200,000 raw ones. Unused credits also expire monthly with no rollover.

Bright Data's proxy and API pricing avoids stacked per-feature multipliers, and its dataset marketplace can eliminate scraping costs entirely for common data needs. Teams running JS-heavy or residential-proxy-dependent workloads at volume often find Bright Data more cost-predictable once ScrapFly's full credit multipliers are factored in.

Migration typically takes 24-72 hours depending on scope. If you're using ScrapFly's generic Web Scraping API for well-known sites (Amazon, LinkedIn, etc.), Bright Data's pre-built structured APIs provide instant equivalents with less custom parsing logic to maintain. For custom targets, teams typically rebuild using Bright Data's Web Unlocker or Web IDE.

The process involves: (1) Mapping ScrapFly's asp=true calls to Bright Data proxy or API equivalents, (2) Testing structured output against existing parsing code, (3) Validating anti-bot bypass on your specific targets, (4) Gradual traffic cutover. Our support team assists throughout the transition.

Both platforms handle anti-bot bypass, JS rendering, and proxy rotation. ScrapFly additionally offers a Cloud Browser API (CDP-driven remote Chromium), a Crawler API for full-site crawls, a Screenshot API, an AI Browser Agent, and an MCP Server for AI agent integrations—all through one shared credit pool.

Bright Data offers proxy infrastructure sold directly, 120+ maintained structured scraper APIs, a browser-based Web IDE, a dataset marketplace, and dedicated ISP proxies—capabilities ScrapFly does not offer at all. Both support Python/Node SDKs and MCP; Bright Data's platform extends further into standalone proxy access and pre-collected data delivery.

ScrapFly is genuinely well-built for API-first developers: a single asp=true flag handles anti-bot bypass, proxy rotation, and JS rendering with no per-target configuration, first-class SDKs (Python, TypeScript, Go, Rust, Scrapy), a CLI for shell/CI pipelines, and integrations with Zapier, Make, n8n, LangChain, and CrewAI. Independent Scrapeway benchmarks rank it #1 for success rate (98%) among tested scraping APIs.

ScrapFly is a strong choice for teams that want one clean API endpoint for arbitrary URLs. For teams needing direct proxy ownership, structured site-specific data, pre-collected datasets, or predictable pricing without credit multipliers, Bright Data's broader platform is typically the better long-term fit.

Yes. Bright Data offers free trials on all products with no credit card required. ScrapFly's free tier (1,000 credits, no card, no expiry) is genuinely generous for prototyping, so many teams run both in parallel: ScrapFly for existing generic scraping scripts, Bright Data for proxy infrastructure, structured APIs, and datasets, before consolidating based on cost and coverage for their specific targets.

Independent Scrapeway benchmarks (Aug 2026) found ScrapFly's average response time (15.3s) slower than the industry average (9.1s), and its average cost ($4.9/1k requests) above the industry average ($2.7/1k)—trade-offs for its #1-ranked 98% success rate. Other gaps: no standalone proxy sales or published IP pool size, no dataset marketplace, no site-specific structured scraper APIs (generic endpoint only), no browser-based Web IDE, no dedicated ISP proxy tier, credits that don't roll over, and no annual plans.

Bright Data's direct proxy access, 120+ maintained structured APIs, dataset marketplace, and Web IDE address these gaps for teams needing more than a single generic scraping endpoint.

ScrapFly uses a single-endpoint architecture: one API call with asp=true routes through one of two proprietary engines (Curlium for HTTP, Scrapium for managed Chromium), handling proxy rotation, rendering, and retries automatically behind the scenes. Development happens via SDKs (Python, TypeScript, Go, Rust, Scrapy) or a CLI—there's no browser-based coding environment.

Bright Data offers multiple approaches: (1) 150M+ proxy IPs sold directly for any use case, (2) 120+ pre-built structured Scraper APIs per platform (zero configuration), (3) a browser-based Web IDE for custom development accessible anywhere, and (4) a dataset marketplace for instant pre-collected data. Bright Data provides more flexibility for teams with mixed technical skill levels, not just API-first developers.

ScrapFly outputs HTML (raw or sanitized), Markdown, plain text, structured JSON via its Extraction API (LLM prompts, CSS/XPath rules, or pre-trained models), screenshots (PNG/JPEG/WebP), and WARC archives for crawl jobs. Integrations include Zapier, Make, n8n, LangChain, LlamaIndex, and CrewAI, plus five official SDKs.

Bright Data supports JSON, NDJSON, CSV, Excel, direct database integrations (MySQL, PostgreSQL, MongoDB), webhook delivery, cloud storage (Amazon S3, Google Cloud), and scheduled exports. Both offer solid integrations—ScrapFly focuses on developer-first output formats for LLM/agent workflows, while Bright Data emphasizes enterprise data delivery and direct database/cloud integrations.

ScrapFly serves 30,000+ enterprises with 15B+ requests/month and 8PB+ data processed monthly, with Custom contracts starting around $1,200/mo and scaling to $30K+/mo for committed concurrency and dedicated residential pools. It's a credible option for large-scale API-based scraping, though premium 24/7 support is gated behind Custom contracts.

Bright Data serves 50,000+ customers including Fortune 500 companies, with infrastructure supporting 650TB of daily data collection, 150M+ directly-accessible proxy IPs, 99.99% uptime SLA, and 24/7 dedicated support included across plans—not reserved for the largest contracts. For enterprises needing direct proxy ownership, structured per-site data, and pre-collected datasets alongside scraping APIs, Bright Data's broader platform scope is purpose-built.

ScrapFly holds a genuinely strong compliance stack: ISO 27001, SOC 2 Type II, SOC 3, HIPAA Attested, and GDPR/CCPA compliance, with a BAA available on Custom plans. This is a real strength worth acknowledging for regulated industries.

Bright Data maintains GDPR, CCPA, ISO 27001, SOC 2 Type II, and CSA STAR Level 1 certifications, with full audit trails and data processing agreements built into every enterprise engagement. Both companies take compliance seriously—the differentiator is that Bright Data pairs its certifications with direct proxy ownership and dataset delivery, which matters for compliance teams auditing where and how source IPs are obtained, not just how API requests are processed.
