When you say sandbox, are you thinking more like a browser devtools panel where you can fork state and simulate concurrent edits visually? Or more of a CLI tool you'd run locally?

Happy to discuss here in the comments too!

Designing Local-First features for Hologram - what's your dream DX? Hi everyone! I’m working on designing Local-First features for Hologram and I’d love to hear your thoughts before I dive into implementation. What do we mean by “Local-First”? The term gets used in ...

I'm designing Local-First features for Hologram (instant UI, optimistic updates, offline resilience) and I'd love to hear your ideas.

What's your dream DX? Don't think about what's possible - think about what you'd want if there were no constraints.

HOLO syntax highlighting.

Nope, Hologram uses stateless HTTP/2 persistent connections - all state lives client-side rather than on the server. So no state is lost during connection interruptions, crashes, or deployments.

Hologram runs on top of Phoenix, so no need to choose! You can add it to an existing Phoenix app and use it for specific pages while keeping the rest as-is. Standalone mode is coming soon too, but for now Phoenix is the foundation.

This was the most requested feature since the project's inception.

Thanks for the support, Jonatan! Good to know the work resonates. Appreciate you spreading the word too 💜

Seeking Sustainable Sponsorship

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 💜

Elixir → JavaScript Porting Initiative

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!

Great idea! Squash and stretch would make it way more dynamic. The beauty of Hologram is you can handle all that animation logic right in Elixir - scaling the ball based on velocity, adjusting the shape on collision, etc. You should totally give it a try and see what you can create!

Absolutely! Game development is definitely one of the exciting possibilities with Hologram :)

They'd need to be rewritten for Hologram's template system since it's not compatible with Phoenix LiveView templates. But the design patterns could definitely carry over.

Hey Shahryar! No, Phoenix components don't work since Hologram has its own template system called "Holo". But Hologram will have its official UI components library to help devs get up to speed really fast!

Thank you Petar! :)
