Open-source alternatives to Uuid

ksuid is a Go implementation of k-sortable unique identifiers. It provides a system for generating globally unique identifiers that maintain a natural chronological order based on their generation timestamp. The project enables the creation of unique keys across distributed systems without a central coordinator. These identifiers are designed for use as database primary keys to maintain index performance and insert efficiency. The library includes capabilities for identifier serialization and parsing, allowing conversion between binary, text, and SQL formats. It also provides command-line to

This project is an implementation of the ULID standard in the Go programming language. It provides tools for generating universally unique, lexicographically sortable identifiers that combine millisecond timestamps with random data. The library ensures that identifiers maintain chronological order through alphabetical sorting. It includes a monotonic generator to guarantee that multiple identifiers created within the same millisecond are produced in a strictly increasing sequence. The project covers unique identifier generation and database primary key optimization. It also provides a comman

Any-rule is a multi-platform regular expression tool that provides a curated catalog of over 70 ready-to-use patterns for validating and extracting common data formats. The project separates its static regex collection from editor-specific plugins, allowing the same pattern library to be accessed through VS Code, IntelliJ IDEA, Alfred Workflow, and a web interface. The tool enables keyword-based pattern retrieval, letting users search for the correct regex by typing descriptive terms rather than remembering exact syntax. It covers a broad range of validation needs including email addresses, U

fast-check is a property-based testing framework and random data generator designed to verify software invariants by producing a wide range of randomized input data. It functions as a test data fuzzer that executes predicates against high volumes of random inputs to uncover edge cases and critical bugs. The project is distinguished by its ability to perform input-shrinking searches, which reduce complex failing inputs to their simplest form to isolate the exact cause of failure. It provides deterministic seed replay to exactly reproduce specific test failures and includes a concurrency testin

nit is a blockchain asset provenance platform and decentralized asset registry. It establishes a verifiable chain of custody for digital media by assigning cryptographically unique identifiers to files and recording their origin, ownership, and modification history on a ledger. The project distinguishes itself by integrating IPFS for decentralized storage and a content versioning system that tracks asset evolution through immutable commits. It includes specialized tooling for generative AI provenance tracking, allowing the recording of creators and tools used in synthetic media to maintain a

go-cursor-help is a machine ID resetter and trial limit bypass tool designed for the Cursor AI editor. It functions as a device identifier generator that modifies configuration files and system registries to regenerate unique hardware identifiers. The utility enables the reset of trial usage restrictions and the recovery of access for accounts flagged for suspicious activity. It achieves this by replacing existing machine identifiers with new, pseudo-random strings to simulate a fresh installation environment. The tool includes a configuration backup utility that archives original system ide

xid is a distributed unique identifier library designed to generate compact, globally unique, and k-sortable identifiers. It functions as a stateless generator that creates identifiers without requiring a central coordinator or network synchronization between instances. The project converts binary identifiers into human-readable, case-insensitive Base32 strings, making the output suitable for use in URLs and web applications. It ensures uniqueness across different processes and hosts by combining high-resolution timestamps with machine identifiers. These identifiers are designed for use as d

Sonyflake is a distributed unique ID library that creates collision-free, chronologically ordered identifiers across multiple machines. It functions as a time-based generator that encodes timestamps into IDs, ensuring that identifiers are monotonically sorted. The system operates without a central coordinating authority, producing unique IDs across distributed nodes without requiring shared state communication or central locks. It prevents collisions between different nodes by incorporating host-aware machine identifiers, which are resolved using private network addresses or cloud instance me

Nanoid is a library for generating unique, fixed-length identifiers designed for distributed systems and database indexing. It produces compact, URL-safe strings by mapping random byte values to a custom character set, allowing for consistent memory allocation and predictable indexing performance across independent nodes without the need for central coordination. The library distinguishes itself by utilizing system-level, cryptographically secure entropy sources to ensure that every generated identifier is statistically unpredictable. This approach provides resistance against collision attack

Proxyman is a cross-platform HTTP debugging proxy that captures, inspects, and modifies HTTP, HTTPS, and WebSocket traffic. It functions as a man-in-the-middle proxy, decrypting SSL/TLS traffic to allow real-time inspection and modification of encrypted requests and responses. The tool is designed for debugging web and mobile applications, with capabilities for API mocking and simulation, scriptable traffic modification, and team collaboration on network logs. What distinguishes Proxyman is its deep integration with mobile and cross-platform development workflows. It provides automated certif

Varnish Cache is an HTTP reverse proxy cache, traffic manager, and edge content delivery tool. It functions as an HTTP accelerator that stores responses in memory to reduce backend load and improve delivery speed. The system also serves as a TLS termination proxy and a configuration engine using a compiled language to define request handling and caching logic. The project is distinguished by its compiled configuration language, which transforms specialized domain logic into machine code to execute request processing at line rate. It provides high-performance memory-centric storage and special
