## Bright Data

Bright Data positions itself as web data infrastructure built for both people and automated agents. The platform bundles four main capability groups: Web Access APIs (Unlocker, SERP, Browser, and Crawl) that fetch and unblock public pages, Proxy Infrastructure spanning residential, ISP, and datacenter IPs, Data Feeds and Scraper APIs that return structured records from well-known domains, and a Dataset Marketplace of pre-collected data. Around those, Bright Data adds agent-facing tooling such as an MCP server and agent browser, plus managed enterprise data acquisition services.

The company reports traction of 50,000+ organizations and advertises an ethically sourced network of 400M+ residential IPs across 195 countries. Product depth is broad rather than narrow: an engineering team can pick a self-serve API, a no-code dataset purchase, or a fully managed acquisition engagement without leaving the same platform and billing surface.

Pricing is usage-based with multiple free tiers and trial credits. Published entry points include SERP API and Unlocker API free tiers, Crawl API from around $1 per 1,000 requests, Scraper APIs from roughly $0.75 per 1,000 records, and Datasets starting near $250 with a 100K record minimum order. Volume discounts, deposit matching promotions, and enterprise contracts are common, so real costs depend heavily on request volume and target site difficulty.

**Pricing & Plans:** Usage-based with free tiers and a free trial. Public starting points include SERP API and Unlocker API free tiers, Crawl API from about $1/1k requests, Scraper APIs from about $0.75/1k records, Browser API from $5/GB, residential proxies from roughly $2.5/GB during promotions, and Datasets with a ~$250 minimum order. Enterprise and managed plans are quote-based.

- **Web Access APIs:** Unlocker, SERP, Browser, and Crawl APIs fetch and parse public pages, handle anti-bot measures and CAPTCHAs, and return results in JSON, HTML, or Markdown.
- **Global proxy infrastructure:** Residential, ISP, and datacenter proxy pools with country, city, and ASN targeting, plus proxy management APIs for rotation and session control.
- **Pre-built scraper APIs and Data Feeds:** Structured endpoints for well-known domains such as LinkedIn, Amazon, and social platforms, delivering fresh records on demand or on a schedule.
- **Dataset Marketplace:** Purchase or filter pre-collected datasets across business, e-commerce, social, and real-estate categories with billions of records available.
- **Agent and developer tooling:** An MCP server, agent browser, SDKs, CLI, and integrations let AI assistants and applications consume web data programmatically.

**Strengths:** Very broad product surface covering proxies, scraping APIs, datasets, and agent tooling in one subscription.; Multiple free tiers and a no-card trial make it easy to validate before committing budget.; Written pricing examples on the site, so costs are estimable up front.; Strong enterprise positioning with compliance messaging, a trust center, and managed services.

**Limitations:** Total cost scales quickly with request or record volume, which can surprise smaller teams.; The number of products and overlapping APIs creates a real learning curve when choosing an approach.; Some use cases rely on sensitive data categories, so legal review is advisable before scraping regulated sources.
