Universal Dependency Resolver

Resolve dependencies across 20 ecosystems — detect conflicts, check system compatibility, and export to any format.

# From any ecosystem, resolve together
udr resolve flask>=2.0 torch@pypi react@^18

# Lock your project's dependencies
udr lock

# Check system compatibility
udr check

# Start the API server
udr serve --port 8000

Install

pip install ud-resolver

Optional extras

Extra	What it adds
`[system]`	GPU & system scanning (psutil, pynvml, cpuinfo)
`[postgres]`	PostgreSQL support
`[monitoring]`	OpenTelemetry, Sentry, Prometheus instrumentation
`[all]`	Everything above

Features

Capability	Detail
20 ecosystems	PyPI, Conda, npm, Crates.io (Rust), Maven (Java), Go Modules, APT (Debian), APK (Alpine), CocoaPods, Homebrew, NuGet, Packagist, RubyGems, Pub (Dart/Flutter), Gradle, Swift, Hex (Elixir), Haskell (Cabal), Docs DB, Custom DB
SAT-solver resolution	Z3-based conflict resolver handles complex cross-ecosystem version constraints
System-aware	Detects OS, CPU, GPU, CUDA, Python, Node.js, GCC, Java — resolution adapts to your environment
GPU-aware	Automatically selects CUDA variants (e.g. `torch 2.1.2+cu121`) when NVIDIA GPU detected
15 export formats	requirements.txt, package.json, Dockerfile, docker-compose.yml, pyproject.toml, environment.yml, Cargo.toml, build.gradle, pom.xml, CMakeLists.txt, install.sh, install.bat, Gemfile, composer.json, go.mod
17 CLI commands	serve, check, resolve, lock, scan, graph, verify, list-ecosystems, update, install, completion, why, outdated, diff, search, details, auth
45 REST API endpoints	Full programmatic API with OpenAPI docs
Desktop GUI	Standalone Electron app — no Python or Node.js needed
Zero config	SQLite by default, in-memory cache, no Docker required
Lock file	Reproducible `udr.lock` with full system snapshot

Quick Start

# Resolve cross-ecosystem packages
udr resolve numpy pandas scikit-learn
udr resolve react vue -e npm
udr resolve serde tokio -e crates

# Lock a project's dependencies
udr lock
udr lock --manifest requirements.txt --dry-run

# Validate lock file
udr verify

# Show dependency tree
udr graph flask django

# Scan a GitHub repo without cloning
udr scan --github https://github.com/user/repo

# System info
udr check
udr info

# List all supported ecosystems
udr list-ecosystems

Use as a Python Library

import asyncio
from backend.core.data_aggregator import DataAggregator
from backend.core.conflict_resolver import ConflictResolver
from backend.core.system_scanner import SystemScanner

async def main():
    scanner = SystemScanner()
    system_info = await scanner.scan_all()

    aggregator = DataAggregator()
    info = await aggregator.get_package_info(
        "torch", ecosystem="pypi",
        include_dependencies=True, include_versions=True,
    )

    resolver = ConflictResolver()
    result = resolver.resolve(
        [{"name": "flask", "version": ">=2.0"}],
        system_info=system_info,
    )

asyncio.run(main())
