Hey Elixir friends! :) Hologram v0.11 is out, now with Elixir regexes running in the browser and client errors that read exactly like server errors, stacktraces included. Plus dynamic tags, attribute and prop spread, and umbrella support. hologram.page/blog/hologra...

I was on the BEAM There, Done That podcast, talking Hologram with Francesco Cesarini and Allen Wyma. Francesco called the idea "Joe Armstrong stubborn" - the browser speaks JavaScript, I made it speak Elixir instead. Happy to own that :) www.youtube.com/watch?v=BOsS...

Hey Elixir friends! :) I just published a post that matters more to me than most - where Hologram's funding stands, what sponsorship built this year, and why what comes next depends on a few companies stepping in. hologram.page/blog/backing...

Hey Elixir friends! :) My ElixirConf EU 2026 talk is online. Hologram lets you build a whole web app in pure Elixir, front end included. This one is about the next chapter - local-first - and why Elixir has an edge JS stacks can't copy. www.youtube.com/watch?v=qqpN...

Most frontend code isn't UI. It's data plumbing - caching, syncing, loading states, and more. Hologram's new Local-First data layer takes it over: declare what the data should be, it syncs itself in the browser, offline included. Pure Elixir. Teaching it hands-on at ElixirConf US, Sept.

Hey Elixir friends! :) Hologram v0.10 is out, now with a real event system. To show it off, I rebuilt Space Invaders in pure Elixir, running in the browser with no game engine. There's a new server-side middleware layer too. hologram.page/blog/hologra...

17 lines of Elixir - all the realtime code you write for a chat room in Hologram v0.9. I'd love to take credit :) but it's an iceberg situation: clustering, cross-node routing, supervision ship with the BEAM. I just built the declarative layer on top. What did the BEAM save you from building?

The Swedish coast, end of September. A seaside theatre full of Elixir people :) I'm speaking at Goatmire about Hologram - building local-first apps in pure Elixir. Offline-capable, auto-syncing, client and server in one language. No JS framework in sight.

Hey Elixir friends, funny how getting a feature down to a simple one-line call takes two weeks of design work. Sharing what that looked like for Hologram realtime.

"Just generate it with an LLM." Common reply when I mention I'm building Hologram UI - the component library for my Elixir-in-the-browser framework. But components need more than markup: a11y, responsiveness, edge cases LLMs miss. Waiting list: hologram.page/ui #ElixirLang

Hi Elixir friends, After 3 years on Hologram full-time (transpiles Elixir to the browser), I'm at a crossroads. 60+ hr weeks balancing contracts & dev isn't sustainable. Where we are & how you can help: hologram.page/blog/seeking... Even sharing helps 💜 #Hologram #Elixir #ElixirLang #BEAM #WebDev

Hey Elixir friends! :) We need help completing Elixir's browser runtime by porting some Erlang functions to JavaScript. No Erlang knowledge required. Each function unlocks multiple Elixir stdlib functions! More here: hologram.page/blog/elixir-... #Hologram #Elixir #ElixirLang #BEAM #WebDev
