| Compare | ||
|---|---|---|
| Verdict | Depends | Depends |
| Best for | JS/TS devs building 2D browser games | 2D browser and mobile-web games |
| Who it's not for | 3D or console game projects | 3D or console-grade games . use Unreal or Godot |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁹ | No dedicated security page; one CVE reported against a community plugin, none found for the core engine. |
| Support quality | Community Discord and GitHub only; no paid support | Community forums; no paid-support evidence |
| Public sentiment | Web devs describe Excalibur as a competent, friendly 2D engine that occupies a different niche than Godot or Unity.⁷ | Gamedevs praise Phaser as lightweight and versatile for 2D web games, but some question its adoption versus Godot and Unreal. |
| Biggest gotcha | Tree-shaking isn't fully optimized yet . expect to ship the whole engine bundle¹ | Editor licences are duration-based; choose term and add-ons carefully before buying14 |
