The Global AgentBuild-a-thon
Build in public. Ship open-source agents. Compete for adoption.
A summer-long global competition for builders creating the next generation of open-source AI agents. Build the next OpenClaw, the next Hermes Agent, the next ZeroClaw, or something nobody has imagined yet.
What is the Build-a-thon?
The Global Agent Build-a-thon is not a weekend hackathon. It is a summer-long competition for builders who want to create open-source agents people actually use.
Participants will build in public, publish weekly demos, open-source their work, track adoption, and compete on a live leaderboard. The best projects will become deployed on Maritime and advance to a final showcase in San Francisco.
What You Can Build
Build an open-source agent, framework, runtime, template, or tool.
Personal Assistant Agent
Build the next OpenClaw-style personal assistant that handles everyday tasks autonomously.
Persistent Agent with Memory
Build a Hermes-style persistent agent with long-term memory, skills, and evolving capabilities.
Lightweight Agent Runtime
Build a ZeroClaw-style lightweight agent runtime that runs anywhere with minimal overhead.
Domain-Specific Agent
Build a specialized agent for founders, researchers, recruiters, educators, operators, developers, or creators.
Deployable Template
Build a deployable Maritime template that others can launch and customize in minutes.
