Chez Scheme is a commercial Scheme implementation by R. Kent Dybvig (author of The Scheme Programming Language), first released in 1985, which uses incremental native-code compilation to produce native binaries for the PowerPC, SPARC and x86 processor architectures.

Chez Scheme has a windowing and graphics package called the Scheme Widget Library, and is supported by the portable SLIB library.

According to several benchmarks [1], Chez Scheme is among the fastest available Scheme implementations.

Petite Chez Scheme is its sibling implementation which uses a threaded interpreter design in place of Chez Scheme's incremental native-code compiler. Programs written for Chez Scheme run unchanged in Petite Chez Scheme, as long as they do not depend specifically on the compiler. Petite Chez Scheme is freely distributable and may be used for any purpose without license or royalty fees [2].
