A developer's buyer's guide to the three most-compared ways to rate limit and protect a Next.js API in 2026: Arcjet (security SDK), Upstash Ratelimit (Redis-backed), and Unkey (API keys + edge limits). Architecture, pricing, bot detection, code, and exactly when to pick each.
A practical Upstash vs Redis Cloud vs Dragonfly comparison for 2026 — the real difference between serverless Redis billed per request, the official full-power managed Redis, and the multi-threaded Redis-compatible engine built for raw throughput. The serverless connection problem, latency, pricing models, features and modules, scaling, the Redis license shake-up, and which one to reach for on a solo project, a high-traffic API, or a template you build and sell.
