| Open-Source Engine | ✓ Open Source (Apache-2.0) | ✓ Open Source (Apache-2.0) |
| GitHub Stars (Repo/SDK) | ★ 26,265 GitHub Stars | ★ 1,719 GitHub Stars |
| Core Repository Language | TypeScript | Go |
| Supported SDK Clients | ||
| Self-Hosted Deployment | ✓ Supported | Hosted Only |
| Docker / Container Ready | ✓ Official Image | ✓ Official Image |
| Model Context Protocol (MCP) | ✓ Native MCP | Standard REST/gRPC |
| Billing Architecture | usage based | usage based |
| Developer Free Tier | ✓ Yes $5 free platform credits / mo | ✓ Yes 3 shared-cpu-1x microVMs allowance |
| Entry Paid Tier (Monthly) | $49 USD / mo | $1.94 USD / mo |
| 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). | Pay-as-you-go billed per second: shared CPU microVMs start at ~$0.0000022/second (~$1.94/month if running 24/7). Stopped machines pay only for attached NVMe disk storage ($0.15/GB/mo). |
| 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. | Operates custom bare-metal servers across 35+ global edge datacenters, booting Linux kernels directly on KVM without container orchestration overhead. |
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
Fly Machines Evaluation
Key Advantages
- ✓ Sub-300ms boot times for custom Docker images running in 35+ global edge data centers close to end users
- ✓ Full persistent NVMe volume support with customizable memory/vCPU ratios per individual machine instance
- ✓ Fast REST API allowing agents to dynamically spawn, pause, snapshot, and destroy microVMs programmatically
Limitations & Trade-Offs
- ✕ Requires managing base Linux Docker images, security firewall configurations, and internal WireGuard routing
- ✕ Lacks a specialized high-level code execution SDK out of the box (requires building custom API wrappers)
