What their customers say

Quotes from people at Flox's customers.

“Flox is all I can expect from a package manager: simple, reliable, efficient, flexible.”

Eric T · @etorreborre

“Every developer has their own long-lived VM and because of that, people have made minor modifications here and there to the system.”

Britt Gresham · @demophoon

“Flox successfully marries the simplicity of traditional package managers with the reproducible, hermetic foundation of Nix.”

Luke Rewega · Software Engineer at Buf · @lrewega

“Flox is a ground up new approach that will undoubtedly become a key part of future toolchains.”

Adam Gross · CEO of Vimeo · former CEO of Heroku, @adam_g

“Flox gives us a lean and secure alternative, plus makes it easy - an excellent double win.”

Guy Podjarny · Co-Founder at Snyk · @guypod

“Flox helps bring simplicity to this space, making it approachable, while not hiding the opportunities and power in the tools.”

Justin Cormack · CTO at Docker · @justincormack

“Flox gives us a dependable foundation so we can move fast with tight feedback loops.”

Samuel Cormier-Iijima · CTO & co-founder · Fellow.ai, Read the case study

“Before, our local dev guide comprised 16 steps with 14 caveats. Now, it’s just a universal flox activate.”

Michael Matloka · Senior Product Engineer · PostHog

“Flox gives us a reproducible foundation we can trust, which matters more and more as our team grows. It also gives us a much more controlled path for shipping software fast and reliably.”

Amin Karbas

““Plus, if something does go wrong, you don’t wonder whether it’s something real ... or an artifact of the machine it was built on. Teams spend less time chasing noise and more time working on actual issues.””

Amin · Resolve AI

““Flox gives you this declarative reference, the Flox manifest, so you don’t have to rediscover what [dependencies] software needs for it to run,””

Amin · Resolve AI

““The Flox environment is declared up front, so shipping downstream gets easier, too: Teams don't guess about what the code needs to build and run. It's defined in the environment."”

Amin · Resolve AI

““Standardization means people focus on building the things we actually need to ship,””

Amin · Resolve AI

““Flox takes a lot of the guesswork out of day-to-day engineering, because you aren't constantly wondering: ‘Is this a real bug in the code or … is it just that something's different on somebody machine?’””

Amin · Resolve AI

““That changed the repo from ‘here’s the code, figure out how to run it’ into something self-contained. You could hand it to someone and be confident they're going to get the same behavior you got,””

Amin · Resolve AI

““People are comfortable using it and ‘works on my machine’ disappears. Flox stops being a thing people have to think about, except to do useful things.””

Amin · Resolve AI

““We weren't spending the same amount of time thinking about the environment anymore, which is exactly what you want,””

Amin · Resolve AI

““You get strong reproducibility on your local machine. When you share what you’ve built, it just works.””

Amin · Resolve AI

““Flox doesn’t make us choose between strong reproducibility and a normal local workflow,””

Amin · Resolve AI

““What I liked about Flox was its simplicity. It allows us to define and work with environments in a way people can read, understand, and use. I didn’t worry about adoption becoming its own project,””

Amin · Resolve AI

““Flox also gives us a much more controlled path for shipping software fast and reliably.””

Amin Karbas · a member of the technical staff · Resolve AI

““Flox gives us a reproducible foundation we can trust, which matters more and more as our team grows,””

Amin Karbas · a member of the technical staff · Resolve AI

“Honestly, Flox mostly sold itself. A person started using it, other people saw they were using it, so they switched to it too. Nobody had any real trouble understanding it,”

Samuel Cormier-Iijima · Fellow.ai

“For most people, after it was set up, Flox just faded into the background. They know it's there, but they don't have to think about it when they're working. It doesn't get in the way. In fact, it's become part of how things work for us.”

Samuel Cormier-Iijima · CTO & co-founder · Fellow.ai

“I liked that Flox would give us Nix-like guarantees under the hood, but in a way that let us get those benefits without the learning curve. Flox was transparent for our team. They didn't have to learn new tools or a new language, or change anything, to work with it.”

Samuel Cormier-Iijima · CTO & co-founder · Fellow.ai

“Flox gives you this declarative reference, the Flox manifest, so you don’t have to rediscover what [dependencies] software needs for it to run,” Amin explains. “Plus, if something does go wrong, you don’t wonder whether it’s something real ... or an artifact of the machine it was built on.

“That's what I mean by ‘producing,’” Amin says. “People are comfortable using it and ‘works on my machine’ disappears. Flox stops being a thing people have to think about, except to do useful things.”
