Hackathon: Relate by Neo4j

Registration here for Relate by Neo4j Hackathon is required. Not on Meetup.

RELATE BY NEO4J

An open-source embedded database for AI agents.
Relate is an open-source embedded database for AI agents and the engineers who build them. It runs as a library inside your application, with no signup or server to deploy.

🌐 THE CHALLENGE: CONTEXT, CONNECTED

Join the Relate by Neo4j Hackathon, a month-long online event celebrating the launch of Relate at NODES 2026.

Build a project that shows how connected data helps agents, apps, or people find and use the relationships that matter. Your project can be new or extend something you already have. Share your code and documentation so others can learn from and reuse your work.

💡 WHAT’S RELATE?
Relate is an embedded database that lets AI agents build and understand relationships across any data. It runs inside your application. Use it from the command line, as a library in Rust or Python, or in a browser tab with WebAssembly. One command installs a skill into the coding agents you already use, so they can find it and start using it on their own. It also stays connected to the Neo4j ecosystem through Cypher, Bolt, HTTP, and MCP.

⚡ INSTALL AND GO
Add Relate to your coding agent with one command. No server to run.

🔎 QUERY THE GRAPH IN PROCESS
Traverse relationships and run vector searches without network calls.

🤖 GET AGENT-READY RESULTS
Return JSON with row limits and errors that explain how to fix them.

🔄 SHARE GRAPH STATE SAFELY
Transactions let multiple agents update the same graph without clobbering each other.

📦 KEEP IT LIGHTWEIGHT
Store each graph in one file, set memory limits, and delete it when you’re done.

🔗 BUILD LOCALLY, CONNECT WHEN NEEDED
Pull a subgraph from Neo4j and query it with Cypher through MCP, Bolt, or HTTP.

🌍 EXPLORE IN THE BROWSER
Use the WebAssembly build to create interactive graph views, with nothing to install.

🏆 PRIZES
Build and share your project for a chance to win a Mac Studio or one of two Mac minis. Prizes are awarded per winning project. (Terms & Conditions & Eligibility can be seen on the Hackaton site)
