Java: The callicoder/java-snowflake repository provides a clear, distributed unique ID generator implementation, often used as a learning resource. Another optimized, high-throughput implementation using Compare-And-Swap (CAS) is available at HMWCS/java-snowflake-id-generator.

Go (Golang): bwmarrin/snowflake is a simple-to-use Go implementation that follows the original Twitter format. Another lock-free, high-scale implementation can be found at godruoyi/go-snowflake.

.NET (C#): JakobKirton/SnowflakeGenerator offers a C# implementation compatible with .NET Standard 2.0 and available as a NuGet package. For a simple and thread-safe generator, see TanerSaydam/SnowflakeIdGeneratorForCSharp.
