Built for the teams building agent systems.
sys9 is in early access. Rather than dress up a logo wall, here’s the honest version: who the agent-native stack is for, and how to get in. If you’re building with agents — one or a hundred — one of these shapes is probably yours.
Find yourself on the list.
Six kinds of teams we’re building with. Pick the one closest to you for the path that fits.
You ship an agent that does real work
Claude Code, Codex, OpenClaw, Cursor, or OpenCode in production. You need a sandbox to run in, files that survive a handoff, and a trace of what happened.
Explore the shape → Multi-agent teamsYou run agents that coordinate
A backlog several agents pull from, mail between them, and a heartbeat that recovers the ones that die — without standing up a pipeline engine.
Explore the shape → AI buildersYou’re building an AI product or pipeline
You need memory that persists, a database, compute that forks out, and a shared filesystem — under one composable roof instead of five SDKs.
Explore the shape → B2B SaaS teamsYou’re adding per-customer AI
Every customer needs isolated compute and data, scoped credentials, and a cost you can attribute — without re-implementing the whole bundle.
Explore the shape → Migrating off DIYYou maintain a homegrown stack
A microVM vendor + object storage + a queue + a vector DB + DIY auth works — but every piece is yours to patch and page on. Trade it for one suite.
Explore the shape → Solo devs & agentsYou just want to start now
Use-first, claim-later: no signup, hand an agent the skill or run the CLI. Build first; attach an account when you’re ready to keep it.
Explore the shape →The runtimes sys9 runs alongside.
sys9 is the substrate, not the agent. It composes under the runtimes teams already use — so adopting it doesn’t mean changing your loop.
Build now. Shape what comes next.

Use-first means you don’t wait for an invite to build — the live services are open. Request access to claim an account and to reach the team.
A direct line
Early-access teams talk to the people building sys9. Tell us what’s missing for your workload and it informs what we ship.
Influence the roadmap
smith9, auth9, and chord9 are on the way. Early partners help decide what those services need to do first.
