The agent-native stack.

Built for agents. Built to compose. Atomic, Unix-like services — each does one job, small and focused — that agents drive through APIs, CLIs, and Skills. Use-first, claim-later: no signup to start.

Built to compose.

Atomic, Unix-like services — each does one job — grouped by what they do. Every product pairs a plain-English label with its xx9 name; opt into only what you need.

Compute Run agents and code.

Sandboxes run9 live

forkable sandbox for agents.

Fork the whole OS in ~50ms; run up to 1,000,000 in parallel, pay only when running.

Browser web9 coming soon

managed browsers for agents.

Headless sessions — stealth, captcha, screenshots.

Data Store state, files, and memory.

Postgres database db9 live

serverless Postgres, from terminal.

Postgres + branching (fork the db, its data, and files together) + file storage with no S3, and zero signup.

Object storage drive9 live

any sandbox, one filesystem.

A shared FUSE filesystem across sandboxes and sessions, with semantic grep.

publish once, any agent installs.

A registry for skills, tools, and MCP.

Evals eval9 coming soon

offline evals, online quality.

Quality signals that complement owl9.

Realtime inbox9 · pulse9 · tape9 live

messaging, presence, streams.

Three atomic realtime services — agent-to-agent mail, liveness, and append-only streams.

Queues task9 live

atomic task claim.

Distributed work-claim; one winner.

Teamwork chord9 coming soon

agents and humans, one team.

Orchestrate heterogeneous agents.

Scheduling cron9 coming soon

cron and triggers for agents.

Run agents on a schedule or on events and webhooks — cron for agent work.

Operate Observe and secure.

Observability owl9 live

agent session observability.

Zero-config capture — wrap the binary, no agent changes; sub-agents auto-traced.

Auth auth9 coming soon

one identity, any sys9.

db9 · serverless Postgres

Serverless Postgres, from the terminal.

Create a database, branch it like code — db, data, and files together — then query straight from your shell. Zero signup, file storage built in, no S3.

Atomic primitives compose into real systems.

The recipe: a shared backlog, agent-to-agent mail, liveness, and agents spun up on demand — together, a hosted Claude Code agent team.

Composition recipe

task9 + inbox9 + pulse9 + smith9 = a hosted agent team.

Drop a job on the shared backlog, spin agents up on demand, let them claim work atomically and coordinate over mail — while liveness auto-unassigns anyone who dies. No pipelines to declare; the workflow emerges.

  ✓ task #41 created
$ smith9 spawn --skill triage
  ✓ agent woke on run9
$ task9 claim 41          # agent
  ✓ claimed · pulse9 holds the lease
$ inbox9 send lead --payload '{"done":41}'

Native to your agent stack

sys9 works with the agents and runtimes you already use — agent-friendly APIs, CLIs, and Skills.

sys9 CLI

Developers

One install, launches everything. The umbrella CLI runs each atomic service — sys9 run, sys9 db, sys9 smith — so you opt into only what you need.

AI agents

Point your coding agent at the sys9 skill and it provisions what it needs on its own — use-first, claim-later, no human in the loop.
