ZLinq is a zero-allocation LINQ replacement library for .NET and Unity/Godot, built on struct-based ValueEnumerable to avoid allocations in method chains. It adds LINQ to Span, LINQ to SIMD, and LINQ to Tree (FileSystem, JSON, GameObject) with 99% compatibility with .NET 10's LINQ.

Use cases

• reduce garbage collection pressure from LINQ chains in C# games
• run LINQ operations on Span<T> without allocations
• use modern .NET 10 LINQ operators in Unity or .NET Framework 4.8
• accelerate LINQ queries with automatic SIMD
• query tree structures like JSON or GameObject hierarchies with LINQ syntax
• drop-in replace standard LINQ for higher performance

When to choose

• you're building performance-critical .NET or Unity applications where LINQ allocations matter
• you want modern LINQ operators on older targets like netstandard2.0
• you need LINQ over Span<T> or SIMD-accelerated sequences

When to avoid

• your project targets platforms without struct generics support
• you rely on LINQ features outside ZLinq's 99% compatibility surface
• allocation overhead is irrelevant and you prefer the standard library
