xid is a globally unique ID generator for web applications.
The project addresses the need for distributed ID generation without relying on a central database or coordination service. It generates IDs that are globally unique across systems, sortable by timestamp, and compact enough for practical use in web services. The approach uses a combination of timestamp, machine identifier, process ID, and a counter to ensure uniqueness while maintaining a small binary footprint suitable for URLs and databases.
Developers should choose xid when building distributed systems that need simple, reliable ID generation without external dependencies or complex setup. It works well for applications requiring sortable IDs that encode temporal information, making it suitable for logging, event tracking, and database record identification. The tool is particularly valuable in microservice architectures where multiple instances need to generate IDs independently without coordination overhead.
The project shows consistent maintenance with regular updates addressing edge cases and performance considerations. Development activity demonstrates responsiveness to reported issues and a focus on stability rather than frequent feature additions. The codebase receives ongoing refinement to ensure the ID generation algorithm remains robust across different deployment scenarios.
