Edge Runtime: What Breaks When You Leave Node.js
Edge runtimes aren't Node.js. No fs, no native modules, no TCP sockets, and strict CPU limits. Know the constraints before you deploy.
True vs Pretend Remote: Reading the Edge Case Signals
The difference isn't in policies—it's in the thousand small decisions that reveal whether remote is core or cosmetic

MCP servers extend Claude Code with custom tools and resources—build them once, reuse across any MCP-compatible AI assistant.
Vercel Analytics vs Third-Party Solutions
Vercel Analytics tracks Web Vitals and pageviews, but lacks JavaScript error tracking, funnel analysis, and session replay. Combine it with PostHog or Sentry for complete observability without redundancy.
Edge Functions Cold Start Optimization
Vercel serverless functions experience cold starts when scaling to zero. Enable Fluid Compute, lazy-load dependencies, and use Edge Functions to reduce initialization latency.
Fluid Compute and Streaming Costs
Fluid Compute charges for Active CPU time, not invocation count. I/O-bound functions get cheaper, but CPU-bound streaming workloads cost more than traditional per-invocation pricing.
