Run thousands of ready-made web scrapers and AI agents from one cloud platform
Over one hundred thousand ready-to-run scrapers and automation tools covering social media, maps, e-commerce, real estate, and general web crawling.

#3
Offers a very similar browser sidebar experience with multiple AI models, but features slightly different pricing and workspace tools.
Free / Open-sourceProvides direct LLM-ready markdown conversion via API, but lacks Apify's massive marketplace of pre-built scraping actors.

SpecialistBuild GTM systems that turn data into revenue

Offers enterprise-grade proxy networks and raw web data infrastructure, but lacks Apify's plug-and-play actor marketplace.
Excels at advanced web automation and data extraction alongside chat, but has a steeper learning curve than Sider.
SpecialistAutomates complex business workflows with AI agents, but is less specialized for raw large-scale web scraping actors.

SpecialistFocuses heavily on pre-built social media automation and lead generation workflows rather than general web scraping.
