Elixir

“So far, CDC has worked very well for us in this manner (Elixir / Postgrex).”

“Having used it in production for years, I can attest that the ecosystem is fantastic.”

“I have worked in production Elixir. (Learning platform supporting realtime student-teacher classroom experience).”

“I'll usually add that ... it's usually a better deal for them. ... Elixir's relative lack of popularity actually leads to an overall more skilled dev pool.”

“I'm now in my 3rd year of doing Elixir full-time. I hope to never again use a language that doesn't have pipes.”

“At kosmi.io we use elixir hot swapping for every small patch/bugfix on the backend.”

“my team has been using Elixir in production (soft real-time distributed systems) for several years to great success.”

“I was... an elixir guy with a lot of FP work in the data space willing to give them a shot”

“I feel mostly insulated from that world now that I'm mainly doing Elixir (Phoenix and LiveView)”

“It was over the course of about three years (2020-2023). Our JS team was made redundant when we switched to LiveView”

“We switched from Java to Elixir and the change has doubled our productivity. Elixir is the most pleasant language I've every worked with”

“It has been a two-year migration, but worth every second. We're twice as productive in Elixir”

“I have a highly-concurrent elixir service I wrote several years ago, by myself... still in production. It pretty much never has problems”

“The fact that you can open a REPL, and open one in prod, do language introspection, inspect data, query DBs with ecto, do hot code swapping is amazing.”

“we have a pretty large codebase at this point that serves 3 different apps... thats exactly what makes elxiir so great.”

“elixir and erlang are amazing tools.”

“I've been using Elixir professionally for seven years across multiple companies”

“I've been using Elixir and Phoenix since 2016. You won't find the dev UX you take for granted in Elixir and Phoenix.”

“We have been working on this (Nx + Axon + Livebook + Bumblebee) for almost 2 years. ... Everything is done in Elixir”

“in the end, completely justified in my case.”

“We use it in production at Amplified! It's been a joy. We train our own large language models and have fine tuned and deployed using Elixir.”

“I work in Rails and Elixir. Feedback is super fast.”

“I used F# a bit and learned a lot from it, and the same with Elixir and Nerves.”

“Fewer programmers with Elixir knowledge (but I think it's a benefit: never have to interview an idiot)”

“We switched when we started an elixir project and pretty quickly switched all our codebases over.”

“this is my attempt to increase the number of people using it in prod.”

“I've been using Elixir/Phoenix every day since 2017 to build apps, glue systems together”

“I particularly enjoy writing tests in elixir compared to any other language so far.”

“in the languages I work with this is not a problem. Mox, for example, is what I use in Elixir”

“Elixir and LiveView are really powerful tools to have in your toolbelt.”

“Maybe I've just been spoiled by elixir (relevant given the OP topic).”

“Having spent the last year with Elixir in production, I don't plan to go back.”

“I've been using Elixir in production for four years now, in a fairly complex SaaS app, and I can comfortably say I've never had to”

“currently my main system in prod is a (very smart) stateless caching system... using elixir really puts you in the mindset of thinking hard about who should have responsibility for "the truth"”

“I'd probably create new projects in Elixir at this point; mix is such a good tool”

“it kept servicing user requests without much of a sweat.”

“The language has few gotchas and is relatively easy to learn.”

“I have been doing this with configurations, so that configs are checked at compile time instead of at deploy time, and I'm pretty happy with it.”

“the elixir backend replaced a flawed stateless django program and has been error-free since we kicked it over”

“it's been a great combination for our company from a tech standpoint”

“Thanks to Elixirs macros, the code for this subsystem is about 75 lines of code and in order to use it in a group of tests it's a single "use" statement”

“I am using elixir for a very important part of a project where I work.”

“I can train a junior on elixir and have them writing code that I am confident won't break the system in prod within three months.”

“We've been building this way ever since we moved to Elixir which makes distributing state across your application easy.”

“Appcues is three years into running Elixir in prod, and we still have not had to set up blue/green deploys”

“We use Elixir very heavily here at PagerDuty. The vast majority of our services are written in Elixir.”

“Coming from a company that uses elixir heavily and has made a significant investment in rust”

“Not to mention all of the intangibles like better tested, healthier codebase.”

“I switched to Elixir/Phoenix and it was great”

“I think Phoenix (and Elixir) is mature enough already to use in production. I use a good mix of Elixir+Phoenix and old-school cron launched Python utility scripts”

“I use both in production. ... Honestly, if Elixir weren't functional I wouldn't be using Phoenix over Rails.”

“Elixir strongly resonates with my own philosophy and all this is just my own opinion on why I chose it”

“Elixir makes it easy to do concurrent batched requests, as well as in memory caches that live for either the duration of the request”

“Elixir has it all (well, almost). It's fast... It has a simple and beautiful syntax.”

“I've been running Elixir in production for half a year now for an app called Sleeperbot”

“Love the language, I've been using it (phoenix) to build a more real-time version of my current rails app.”

“it's been an excellent choice. Elixir is totally compatible with existing erlang code”

“Elixir lets me use a lot of the stuff I learned with Haskell, and I've already used it building a real time component for an app I'm working on.”
