Elixir devs who haven't tried Hologram yet, what's stopped you?

Building a framework is two jobs, the framework and getting people to use it. I'm on the second one now, so here I am asking. Vote below, or reply, blunt is welcome. DMs open too, and reposts help a lot.

Dillon O’Connor moved Combat Log’s frontend to Hologram one page at a time. It now has 16 pages and 99 components.

His write-up covers why he chose it, what worked, and what he’d still like improved:

We helped @lonelyplanet modernize its content infrastructure and build Elixir backends for its mobile app and website redesign.
Our role covered backend development and platform architecture. Working within Lonely Planet’s backend team, our engineers took ownership of key services across four areas:
➡️ CMS integration: processing content changes from the new headless CMS and extending a unified GraphQL API to merge its content with legacy Drupal data. The migration progressed without disrupting production traffic.
➡️ Mobile backend: building a Backend for Frontend for the Flutter travel app, assembling data from multiple services into the responses needed to render each screen.
➡️ Website redesign: designing and building a separate Backend for Frontend for the new web experience.
➡️ Observability: improving consistency in performance metrics and service health monitoring across the platform’s microservices.

Built on Elixir, AWS, and Kubernetes, the work gave Lonely Planet a maintainable backend foundation for both web and mobile, while allowing the old and new content systems to coexist during migration.

Built an app with Hologram or a library for it? @Bart_Blast created a Showcase to collect Hologram projects and help developers considering Hologram see what others are building.

We’d like to help more of them get seen. Submit yours:

Finding vulnerabilities is getting cheaper. Fixing them is not.

On 8 October, @AnthropicAI opened OSS Scanner: free, periodic scans for eligible open-source projects. Reports are model-generated and not reviewed by a person before they reach maintainers. Each comes with a reproducer and, where possible, a candidate patch. Anthropic says its models flagged over 29,000 candidate vulnerabilities in six months, and that in an expert check 85 of 97 critical and high-severity findings (88%) met its disclosure bar.

A day later, the BEAM There, Done That podcast asked Ingela Andin, who has maintained the TLS stack in Erlang/OTP for over 20 years, what happens on the receiving end. AI agents help narrow down and summarize a report; a person verifies it. Fixes are patched across three supported OTP releases at once, and CVE and SBOM records are published through the EEF's CNA on release day.

For teams running Elixir in production, the work moves downstream:

→ Stay on a supported OTP release, so security fixes reach you as an upgrade, not a migration.

→ Contribute local OTP patches upstream. A private patch has to be carried forward on every upgrade, which slows down each security update.

→ Put security checks in CI: Sobelow for your own code, and a dependency scan for mix.lock (for example Google's OSV-Scanner GitHub Action). In our State of Elixir 2025 survey, 69.6% of respondents used Credo, but only 29.5% used Sobelow.

→ If you maintain a library, publish a security policy and enable private vulnerability reporting.

How long does it take your team to ship an OTP or dependency security update today?

We’re looking for a React Native developer at Curiosum: full-time, fully remote, for a long-term B2B/freelance contract.

You’ll work on a medtech project for our client in Germany, with the possibility of contributing to more of their products over time.
👉 Independence matters to us. We’re looking for someone who can take a problem, figure out how to solve it, and deliver the solution. We also expect AI tools to be a regular part of your day-to-day development work.

The stack: React Native and TypeScript, with Elixir on the backend.
A couple of practical details:
👉 You must be based in the European Union.
👉 Start date: 1 November, with an earlier start potentially possible.

If this sounds like an opportunity for you, send us a DM or email [email protected].
And if someone comes to mind, tag them in the comments or share this post with them.

Last week, Marta Habdas and Bart Blast represented Curiosum on stage at Goatmire in Varberg, Sweden.

In “Controlled Noise on Nerves”, Marta explored how to turn noisy sensor readings into musical control.

Bart, the creator of Hologram, presented “Hologram in Practice: A Local-First App in Pure Elixir”.
👉 https://t.co/0S8RSiety1

Sharing the work behind these talks is part of how the Curiosum team contributes to the Elixir ecosystem, giving other developers ideas and approaches they can build on.
Proud of Marta and Bart, and grateful to the Goatmire team for bringing the community together!

It’s been a while since we mentioned our LinkedIn group, Elixir Community by Curiosum.
Share an Elixir project, article, or question. Get feedback, exchange ideas, or read along.

If you know our https://t.co/NW3X7ExDnA, the group complements it with something we want to make more room for: conversations between the people who build, share, and use those resources.

Join it and tell us what you’re working on:

Elixir devs were already using AI heavily in 2025:
Claude Code 55.2%
Tidewave 32.3%
Copilot 32%
Cursor 24.8%
But reported productivity impact averaged just 3.01/5.

The next State of Elixir survey will show what changed.

@Bart_Blast's talk at #ElixirConfUS is now available online to all.
The talk shows the local-first data layer he’s been building for Hologram, including a demo with two browser windows going offline and syncing back up. He also gets into how Hologram decides what data a page needs to sync and how conflicting edits are merged.

We support Hologram as a sponsor, so it is great to see this work presented to the wider Elixir community at @ElixirConf US.
➡️ Watch Bart’s talk: https://t.co/0tjA11WyJZ

Are you already using Hologram? We’d be interested to hear what you’re building with it.
If you haven’t tried Hologram yet, what would you want to know before starting?

In our 2025 Elixir Survey, 85.7% of respondents said they used Phoenix LiveView. How would that number look this year?
The Elixir ecosystem keeps changing, and there are more things worth measuring now - Hologram is one example, but probably not the only one.

What numbers, trends, tools, or changes in the Elixir community would you like to see reflected, what is interesting for you, or can help you at your work?

Share your ideas in the comments.

Schema changes get harder when producers and consumers deploy independently.
For additive changes, update the consumer first, so it accepts v1 and v2 before producers start sending v2.

If legacy support grows, isolate it in a compatibility layer.
