| Developer / Organization | Mendable AI | Fly.io Inc. (Kurt Mackey & Team) |
| Open-Source Engine | ✓ Open Source (AGPL-3.0) | ✓ Open Source (Apache-2.0) |
| GitHub Stars (Repo/SDK) | ★ 195,258 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 500 scrape credits / mo | ✓ Yes 3 shared-cpu-1x microVMs allowance |
| Entry Paid Tier (Monthly) | $16 USD / mo | $1.94 USD / mo |
| Pricing & Cost Architecture | Monthly credit quota: Free tier provides 500 scrape credits/mo (1 page = 1 credit; 1 crawl = 1 credit per discovered page). Starter plan is $16/mo for 3,000 credits ($0.0053/page). Growth is $99/mo for 100,000 credits. | 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 | Created after developers struggled with fragile Puppeteer scripts for RAG; its scraping cluster processes millions of web pages weekly with automated proxy rotation and stealth headers. | 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
Firecrawl Evaluation
Key Advantages
- ✓ Converts complex JavaScript-rendered SPAs and shadow DOM into clean, structured markdown optimized for LLM tokenization
- ✓ Includes built-in automated anti-bot bypass, residential IP rotation, and captcha handling with no external proxy configuration
- ✓ Official Model Context Protocol (MCP) server support and official SDKs for Python and TypeScript
Limitations & Trade-Offs
- ✕ AGPL-3.0 copyleft license requires open-sourcing modifications when self-hosting in proprietary environments
- ✕ Credit consumption scales rapidly on deep recursive crawls across multi-page domains
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)
