Discover what makes Flux faster, simpler, and more powerful than other JavaScript package managers.
The Problem with Traditional Package Managers
Most developers today rely on package managers like npm, yarn, or pnpm to manage their dependencies. While these tools work, they come with trade-offs:
- Slower installation times due to legacy architecture
- Confusing lockfile formats and bloated caches
- Inconsistent CLI behavior across ecosystems
- Lack of native script execution and management features
- Poor developer experience and unintuitive error messages
Why Flux Exists
Flux is built from the ground up to solve these pain points. It is not just a package manager — it's a developer-first, performance-obsessed toolkit for building modern JavaScript and TypeScript projects.
Here’s what makes Flux stand out:
Blazing Fast
Flux is faster than npm, yarn, and pnpm. By using optimized algorithms, smarter caching, and parallelized workflows, Flux can install and resolve packages in a fraction of the time.
- No global cache
- Deterministic and lean installs
- Built with performance-first philosophy
Smarter Dependency Graph
Flux generates and handles a highly efficient internal dependency graph. This reduces unnecessary installations and eliminates redundancy across workspaces and modules.
Unified Dev Workflow
From init to install, run, build, and uninstall, Flux provides a cohesive CLI you can rely on. One tool for everything — no more flipping between npm, npx, yarn, or turbo.
flux init my-app
flux install react
flux run dev
flux uninstall lodashNative Script Runner
Unlike npm run or yarn, Flux has a native script runner that gives better performance and clearer output, while also supporting enhanced options like parallel, sequential, and conditional execution.
Minimal & Modern
Flux has no unnecessary legacy baggage. It works seamlessly with ESM, TSX, modern import maps, and is designed with today's developer stack in mind.
Speed Comparison
Here’s how Flux compares to other package managers in real-world tests on large projects:
| Tool | Cold Install | Warm Install |
|---|---|---|
| npm | 22s | 12s |
| yarn | 19s | 10s |
| pnpm | 13s | 7s |
| Flux | 6s | 2.5s |
Flux performs nearly 3x faster on cold installs and up to 4x faster on warm installs.
| Tool | Uninstall react |
|---|---|
| npm | 6.2s |
| yarn | 4.8s |
| pnpm | 3.3s |
| Flux | 1.5s |
Flux uninstalls packages over 2x faster than pnpm.
| Tool | Update all packages |
|---|---|
| npm | 14.5s |
| yarn | 12.9s |
| pnpm | 10.1s |
| Flux | 4.3s |
Flux updates your dependencies faster with zero config required.
