LONG-HORIZON CONTEXT
Agent Memory Layer
Decisions, files, and intent stay available as sessions grow from minutes to weeks.
✦ Built for teams shipping with agents
All your agents.
One multiplayer session.
Multiplayer is the agentic development harness where your team and its coding agents work together, in the same session, with shared context.
Fragmented agents are
slowing your team down.
Separate agents lose context, repeat decisions, and turn parallel work into another coordination problem.
Context disappears between sessions
Every model works in isolation
Agents duplicate the same work
Tooling breaks the coding flow
THE MULTIPLAYER HARNESS
Meet the session
where agents ship together.
Shared state, shared intent, and a live view of every agent working across your codebase.
ONE HARNESS
A complete system for
agentic development.
Every layer is built by us for speed, long-horizon reliability, and a smooth team workflow.
INTELLIGENT ROUTING
Model Fusion Router
Route each step to the right model and combine their strengths inside one coherent run.
BUILT BY MULTIPLAYER
Multi-Agent Mode
Cheap models compete, critique, and converge on frontier-quality output for dramatically less.
OUR OWN STACK
Harness + CLI
A native harness and a fast CLI, designed as one system so coordination never interrupts flow.
WHY MULTIPLAYER?
Coordination becomes
the advantage.
Your agents do not just run beside each other. They share a durable understanding of the work.
92% context retained
5x faster handoffs
41% fewer retries
68% lower model cost
