If you're building distributed systems in .NET, generating unique IDs efficiently can become a real challenge. GUIDs are too long and not index-friendly, database auto-increments don’t scale, and external ID services add extra overhead.
So I built Jordium.Snowflake.NET — a fast, configurable, and dependency-free ID generator based on the Snowflake algorithm, designed specifically for .NET developers.
🚀 Why Use It?
High throughput — capable of generating millions of IDs per second
Configurable — customize data center ID, worker ID, and sequence bits
Zero dependencies — no Redis, no DB, no external service needed
Production-ready — ideal for microservices and distributed systems
MIT licensed — open, simple, easy to adopt
🧩 Use Cases
Primary keys in distributed databases
Order numbers and payment transaction IDs
Logging, tracing, and event correlation
Any system requiring high-volume unique identifiers
🛠️ Quick Start
using Jordium.Snowflake;
var generator = new SnowflakeIdGenerator(1, 1);
long id = generator.NextId();
Console.WriteLine(id);
That’s it — globally unique, sortable 64-bit IDs with almost zero overhead.

Hey dev community! 👋
Last week I launched Jordium.Snowflake.NET(github.com/nelson820125/Jordium.Sn...), a fast and easy-to-use Snowflake ID generator built for modern .NET apps.
Super happy to share that it has already reached 1.1K+ downloads on NuGet.org in just 7 days 🎉
Huge thanks to everyone who tried it out, shared feedback, or integrated it into their projects!
The project supports:
.NET 6 / .NET 8
.NET Framework ≥ 4.6.1
.NET Standard 2.0
High-throughput, low-latency ID generation
Clean and minimal API
I’ll continue pushing updates and would love to hear your suggestions or feature requests.
If you're building distributed systems and need reliable 64-bit IDs, feel free to give it a look!
