Overview
An application platform for teams whose code is written by agents. Every agent gets its own sandbox running your whole stack; staging and production run the same manifest.
Parity hosts your application: its services and the built-ins they use, Postgres, Redis, S3, SMTP, Auth and certificates. You describe the app once in parity.yaml. From that file Parity runs production, a staging environment that matches it, and a sandbox for every agent and every branch.
A sandbox is the whole stack. Each one is a Kubernetes namespace with its own built-ins, generated credentials, inbox and OIDC issuer, behind a default-deny network that only reaches the hosts you list. Agents drive it through the CLI, the API or MCP, and hand reviewers a signed record of what they did.
The model
| Term | What it is |
|---|---|
| Project | One application and its repository. It holds the manifest, members, secrets and environments. |
| Manifest | parity.yaml: the app's services, built-ins, jobs and egress allowlist. One file for every environment. |
| Sandbox | A short-lived copy of the whole app for one task, created by parity up. |
| Build | One commit's images and the rollout steps they ran in each environment. |
| Staging | Follows your default branch. Every merge builds and deploys to it. |
| Production | Changes only when someone promotes a build that passed staging. |
