agentmash launches multiplayer coordination for coding agents.

agentmash targets the real bottleneck of parallel agent development: coordination, not code generation. Its promise is compelling, but advisory warnings cannot fully prevent semantic conflicts without strong team workflows.

• –Shares file, branch, and task context across agents before writes occur.
• –Supports multiple agents and models through desktop, CLI, hooks, and MCP.
• –The company reports 98.6% of overlapping work caught before edits, versus 55% without the product.
• –BYO-model pricing keeps agent usage separate from coordination costs, with a free tier for two developers.
• –Privacy and trust will matter: code stays local by default, but metadata and optional diffs still leave the machine.
