Godot Engine

Open source · OSI-approvedStatus: unknown

Free 2D and 3D game engine with no royalties

Godot ships a complete engine, editor, and export pipeline under the MIT licence, which means no royalties, no revenue thresholds, and no licensing conversation before a project starts.

Its 2D renderer is genuinely first class rather than a layer over the 3D one, and the scene and node model is unusually easy to reason about. GDScript keeps iteration fast, and C# is available for teams who want it.

Decisive facts

  • Dedicated 2D engine alongside a full 3D renderer
  • GDScript, C#, and a C++ extension interface
  • Export to desktop, mobile, console, and web from one project
  • Node and scene composition model with live editing while running
  • MIT licensed with no royalties at any revenue level

Collaborative whiteboard with a hand-drawn look

Excalidraw's sketchy rendering is not decoration. Diagrams that look provisional invite comment, where a crisp vector diagram signals a decision already made, so it is unusually good at the early part of a design conversation.

AI coding agent for terminal, editor, and desktop

OpenCode is a coding agent that runs where you already work rather than in a separate chat window. The same session can be driven from a terminal, an editor extension, or a desktop client, and it keeps context across all three.

Let AI agents drive a real browser

Browser Use gives an agent a real browser rather than an HTTP client. It handles the translation between a model's intent and DOM actions, keeps a structured representation of the page in context, and recovers from the usual navigation failures.
