Time to wrap up the year, let’s look at some numbers πŸ€“

But before we do: thank you everyone for supporting Gleam's journey in 2025!

Huge thank you to every contributor, sponsor, supporter, to all the Gleamlins and Gleam-curious people. You rock! ⭐

I haven't posted any Gleam videos in a little bit, but that doesn't mean I haven't been doing anything at all!

I mean, it's gotta be Gleam, really. I've done a lot of other 'cloud' languages (Python, Rust, TS, Go), but Gleam was my first function language, and it's so approachable! And generally just a joy to write

I have once again been nerd-sniped by @lpil.uk into writing a Gleam package.

This time, it's a lightweight, high-perf client for Redis-compatible databases, called Valkyrie!

The library includes a connection pool, and has been tested against Redis, Valkey, KeyDB and Dragonfly.

What happens when you fall into a new language by accident? @ihh.dev ’s journey into Gleam proves it might just be the best mistake you ever make. codebeamstockholm.com/talks/Jumpin...

When asked what they liked about Gleam, developers responded with:

"It's very braindead"
"Gleam is Haskell for normies"
"The core team is very fasionable"
"I don't have to configure TS"

I think I've picked the right language

How we rewrote OpenFGA in pure Postgres TL;DR: We rewrote parts of OpenFGA in pure Postgres to make it easier to keep our authorization system up-to-date with our main database.

Rover's own @ihh.dev takes us through how we implemented our own ReBAC auth system in our latest blog post

Somehow, it's the least painful infra work we've ever done
