Invariant
Invariant is an isolated environment manager for coding agents that provides persistent Linux containers, parallel experiments, and shared test checks.
Invariant provides persistent, isolated Linux environments for coding agents, allowing system packages, language runtimes, and home-directory configurations to survive between runs. It manages agent sessions, saved environments, and parallel experiments using Docker as the Linux runtime. Users can run configurations in parallel on the same task, evaluate them with shared checks, and review the changes they want to keep. The platform integrates with the native Codex CLI and supports macOS and Linux hosts. It is designed for developers who want to give coding agents their own tools, pick up where they left off in chats, and run consistent evaluations across multiple trials. Users can export reports in Markdown, JSON, or CSV formats.
