Entry Paid Tier (Monthly) $49 USD / mo Free / Custom
Pricing & Cost Architecture Free tier includes $5/mo in platform credits (~12 compute units). Starter plan is $49/mo ($49 prepaid usage) at $0.40 per Compute Unit (1 CU = 1GB RAM for 1 hour). Developer free tier provides $100 in trial compute credits. Standard compute is metered per second, starting at ~$0.05/hour per active vCPU with zero idle sandbox costs.
Key Engineering Insight Maintains Crawlee, one of the most popular open-source scraping libraries, and hosts a marketplace of over 2,000 ready-made cloud Actors for LLM data ingestion. Built on AWS Firecracker (the microVM technology powering AWS Lambda); boots isolated Linux environments in under 150 milliseconds to safely execute untrusted AI-generated code.

Strengths & Trade-Offs

Objective engineering evaluation of both platforms

Apify Evaluation

Key Advantages

  • ✓ Hosts over 2,000 pre-built scraping and automation Actors for major web services and marketplaces
  • ✓ Maintains Crawlee, the gold-standard open-source scraping library with automated proxy management and fingerprinting
  • ✓ Official Model Context Protocol (MCP) server support and official SDKs for Python and JavaScript

Limitations & Trade-Offs

  • ✕ Pricing based on Compute Units (CUs) can become complex to project across large multi-actor agent workflows
  • ✕ Free tier $5 credit allowance is shared across storage, data transfer, and actor compute

E2B Evaluation

Key Advantages

  • ✓ Hardware-isolated microVMs powered by AWS Firecracker with sub-150ms cold start initialization
  • ✓ Custom sandbox templates allowing developers to pre-install specific system packages, Python wheels, and binaries
  • ✓ Official SDKs for Python and TypeScript with native stdout/stderr streaming and artifact file downloads

Limitations & Trade-Offs

  • ✕ Maximum continuous session execution duration capped at 24 hours per persistent sandbox instance
  • ✕ Requires configuring custom egress firewall rules if sandboxes need to access private local enterprise APIs
