jMonkeyEngine Is Dead. Long Live rCrabEngine

Hello Crabs ,

After careful consideration, extensive community feedback, and several highly scientific alignment meetings with ChatGPT and SuperGrok , we have decided to move forward with an immediate and substantial change for the engine.

Effective today, jMonkeyEngine will be known as rCrabEngine.

As part of this exciting new chapter, we will begin a full migration of the engine codebase to Rust and retire all legacy Java repositories within the next std::time::Duration::from_secs(172_800).

This transition will modernize the platform, strengthen our ownership strategy, and replace our primate-based architecture with a more future-proof, resilient decapod model.

We understand this is a major change, and we thank the community for its continued support during this inevitable transformation.

Why jMonkeyEngine is becoming rCrabEngine

• Memory safety : Java is memory-safe, but Rust is memory-safer, according to people with anime profile pictures on Reddit.
• Environmentally friendly : No more garbage collection. We are reducing waste and saving 50% more water per allocation.
• Biologically inspired success-story : Everyone knows crabs are not a species, but an evolutionary endgame. This is a major upgrade from our current primate-based architecture.
• Enhanced branding and mascot : People kept asking whether we were furries. After careful consideration, we decided to join the Rust community and stop arguing semantics.
• Better ownership model : We take a hard stance against “you will own nothing and be happy.” In Rust, you own your objects. You may still be unhappy, but now it is enforced at compile time.
• Reduced code clarity : Open-source projects are increasingly receiving vibe-coded PRs. We felt letting them stand out was unfair, so we reduced overall clarity to help them blend in.
• No more GC pauses : The only pauses now will be developers staring at borrow-checker errors in complete silence.
• Stronger community engagement : Rust developers already market Rust full-time for free, so we are strategically repositioning ourselves to benefit from this renewable resource.
• Cargo integration : We can now ship plugins as .crate files instead of .jar files. Jars are round and inefficient. Crates stack properly. In hindsight, Java was never serious about logistics.
• Zero-cost abstractions : We will no longer charge $0.10 per abstraction.
• Backward compatibility : Existing Java projects will continue to work after a simple and straightforward full rewrite.

We have already moved to the new rCrabEngine organization and ported a concerning amount of the engine to Rust.

It is still early, so many things are broken, but that has never been considered a blocker in the Rust ecosystem. The crab does not move forward — it moves sideways.
