Scion is an open-source, experimental orchestration platform from Google Cloud Platform for teams of AI agents and the people working with them.
Follow Scion to get an email when its listing changes, such as new pricing or features. One digest a day at most, and you can unsubscribe anytime.
It runs harnesses such as Claude Code, Antigravity, Codex and OpenCode as independent containerized agents with their own roles, configuration and credentials, letting them delegate tasks, share findings and work in parallel locally or on cloud infrastructure.

Open Source
Free and open source under the Apache-2.0 license; you supply your own coding-agent harness subscriptions or model credentials and container or cloud infrastructure (Docker, Podman, Apple Container, Kubernetes or Cloud Run).
Best for
Engineers and teams experimenting with multi-agent collaboration patterns who want to orchestrate several off-the-shelf coding agents in isolated containers, from a laptop up to a shared hosted Hub.
Not ideal for
Teams that need a stable, supported product; Scion is pre-1.0, its APIs and configuration change between releases, and it is not an officially supported Google product.
A serious, fast-moving testbed for multi-agent orchestration backed by Google Cloud engineers, with broad harness and runtime support; best treated as an experimental platform rather than production infrastructure.
Open-sourced in April 2026 (covered by InfoQ); the repository publishes nightly builds (latest nightly-20261022) and receives daily commits, with Homebrew installation via the community homebrew-scion tap and Workstation, hosted Hub and Kubernetes runtimes in active use.
