The agent-native stack.
sys9 is a stack of small, focused cloud services built for the way agents actually work. Our whole philosophy fits on one line: built for agents, built to compose.
Give agents a cloud that fits how they work.
Most cloud infrastructure was designed for humans clicking dashboards and apps making steady requests. Agents are different: they spin up by the hundred, run in bursts, hand work to each other, and need to act before anyone has signed a contract. sys9 is the stack built for that reality — so a developer (or an agent) can go from idea to a running, isolated, observable system without gluing five vendors together.
Two principles, applied everywhere.
Agent-native
Agent-friendly APIs, CLIs, and Skills. Use-first, claim-later — no signup to start. Hand an agent the skill and it provisions what it needs on its own. The interface assumes the caller might be a model, not just a person.
Unix-like atomic services
Each service does one job, small and focused. Less context for the agent to carry,
fewer tokens to spend, and freedom to compose. Opt into exactly the pieces you need
— db9, run9, drive9, task9
— and leave the rest.
Builders of agent systems.
Agent developers
People building coding agents, multi-agent teams, and AI pipelines who need real compute, data, and coordination.
B2B SaaS teams
Teams shipping per-tenant AI features who need isolation and cost control without building it from scratch.
The agents themselves
Use-first, claim-later means an agent can provision and compose sys9 services autonomously — the way the stack is meant to be used.
Three layers, bare CLI names.
The brand is sys9; the tools are db9, run9, drive9, and friends. One umbrella CLI installs and launches them all.
mem9, chord9 — the agent-facing apps: one memory across agents, and agents and humans on one team.
run9, db9, drive9, owl9, smith9, auth9 — compute, data, storage, observability, hosting, and identity.
task9, tape9, inbox9, pulse9 — atomic building blocks: task claim, append-log, messaging, liveness.
Built for agents. Built to compose.
