PrinceJS vs Hono vs Express vs Elysia: Benchmarking the Fastest Bun Frameworks in 2025

PrinceJS is a new Bun framework created by a 13-year-old from Nigeria that ranks third in performance benchmarks at 21,748 req/s, only 1.7% behind Hono and 2.3x faster than Express. Despite being third in raw speed, PrinceJS differentiates itself with a 4.8kb gzipped bundle size, 97ms cold start on Slow 3G, and a full production feature set including OpenAPI docs, SQLite, WebSockets, and multi-platform deploy adapters. The article recommends PrinceJS for edge functions and serverless use cases where bundle size and cold start matter, Elysia for maximum throughput, and Hono for its middleware ecosystem.
