On April 15, 2026, RZLT hosted the second Claude Code Meetup in Zagreb, and the city showed up exactly the way it did the first time. Over 100 people filled the room, standing space only, with conversations running in the hallway before the first speaker even started. The energy in the room was the same as Meetup #1 with builders, founders, developers, and product people who came to hear from practitioners, not theorists, and who stayed well past the scheduled end time because the conversations were worth staying for.

The format was the same as the first edition: no sponsor slots, no panels, just five speakers with something real to share and a time limit to share it in.

What the Evening Covered

The agenda for Meetup #2 ran five talks across 30 and 15-minute slots, covering some of the most actively worked problems in the AI space right now.

Mislav Javor, VP Product at Biconomy, opened the evening with a look at Project Glasswing and Mythos, covering how Biconomy is thinking about AI-native infrastructure and what building for autonomous agents looks like at the infrastructure level.

Ivan Belas, CTO and Co-Founder at Robotiq, followed with a talk on AI and agentic systems drawn from Robotiq's experience deploying these systems in production environments where the stakes are real.

Gal Tidhar, Senior Software Engineer at Sederic, walked through taking code from a Claude Code prompt all the way to a running production feature, including a look at local LLM hardware setups that let teams run models entirely on-device.

Filip Blagojevic, Founder and CEO at Resomnium, covered persistent memory for persistent agents, one of the more fundamental unsolved problems in building agents that actually work across sessions and over time.

Goran Cvijanovic, Senior Software Architect at Reversing Labs, closed the evening with CameoDB, an open-source document store and full-text search engine built specifically for AI agents and available on GitHub.

Tools and Projects That Surfaced During the Evening

Beyond the scheduled agenda, a number of tools and projects came up during the open floor that are worth keeping on your radar.

LeanCTX is a token usage optimization tool that reduces consumption across Claude Code, Cursor, and Copilot by up to 99%, which at the scale production agentic workflows operate at is a genuine operational cost c onsideration rather than a minor tweak.

Gastown is a multi-agent workspace manager built for coordinating parallel Claude agents across sessions, handling the coordination overhead that becomes the binding constraint when you are running multiple agents at once.

Superpowers is a structured Claude skill set toolkit for developers, designed to make Claude's behavior consistent and reusable across different projects and workflows without re-prompting from scratch each time.

Redline is a statusline plugin that visualizes context window usage and quota consumption in real time, includes a hint when a new version of Claude Code is available, and offers a /changelog command to surface the latest changes.

From Code to Running Feature is the full talk and materials from Gal Tidhar's session, covering the complete Claude Code workflow from prompt to production feature, available online for anyone who wants to go through it in detail.

Gal's talk also covered three local LLM machines worth knowing about for teams that want to run models entirely on-device: the HP ZGX Nano G1n AI Station, the ASUS Ascent GX10, and the Lenovo ThinkStation PGX SFF.

CameoDB is an open-source document store and full-text search engine built specifically for AI agents, available on GitHub, and was covered in depth in Goran Cvijanovic's closing talk.

What Two Meetups in Zagreb Have Shown

Across the two Claude Code Meetups RZLT has run in Zagreb, over 200 people have shown up, every speaker has come with production experience rather than a roadmap, and the conversations have consistently run past the scheduled end time because the room does not run out of things to ask. The Zagreb builder community is not arriving at these events to be introduced to Claude Code. It is arriving to compare what it has already built with it, to surface the failure modes it has run into, and to work out what the next problem is.

The third Zagreb meetup is in the pipeline. And if you are a builder working on something worth sharing, whether it is a workflow, a tool, or a failure that produced useful knowledge, get in touch. The stage is open.

The second Claude Code Meetup Zagreb was organized by RZLT. Special thanks to Mislav Javor, Ivan Belas, Gal Tidhar, Filip Blagojevic, and Goran Cvijanovic for their presentations and to everyone who attended.
