Hologram is making Local-First possible - with pure Elixir, running right in the browser. This talk showcases those capabilities in action - building applications that work offline, sync data automatically and declaratively, and run entirely in Elixir on both client and server, end-to-end. I’ll walk through the architectural decisions that make Local-First patterns possible and show how developers can start building Local-First applications with Hologram. Attendees will see working code, understand how Hologram brings Local-First to the Elixir ecosystem, and leave equipped to take their first steps building Local-First applications in pure Elixir.
Key takeaways:
- How Hologram makes Local-First possible with pure Elixir in the browser
- How Hologram handles data syncing automatically and declaratively
- What architectural decisions enable Local-First patterns in Hologram
Target audience:
- Elixir developers building web applications. Especially valuable for those exploring alternatives to JavaScript-heavy frontend stacks or interested in Local-First architecture, as well as anyone who saw the Hologram introduction at ElixirConf 2025.
