What is Polygraph?

Polygraph is a meta-harness for AI agents—it gives them visibility across every repo boundary and memory that survives every session. It indexes every repository you have access to (both private and open source) and builds a graph of how they relate via packages and APIs. Your agent uses this graph to plan cross-repo work without needing to be told where to look, effectively turning your codebase into a synthetic monorepo. Polygraph isn't an agent itself; it's the infrastructure that lets agents take on more ambitious tasks.

Application scenarios

  • Cross-repo development

    Prompt once and land changes across multiple repositories automatically.

  • Automatic repo discovery

    Polygraph indexes all repos you have access to, so agents can find and work with them without manual setup.

  • Testing and previewing downstream

    Test changes and preview their impact on dependent repositories before merging.

  • Unified PR and CI management

    Manage pull requests and continuous integration from a single place.

  • Session handoff

    Share a session across any agent, including repos, branches, PRs, and logs, so no one re-explains anything.

  • Bug fixing with history

    Reference any past session—Polygraph brings back its description, PRs, and traces, so you fix bugs without digging through history.

Core Features

  • Cross-repo unity

    Prompt once and have your agent work across every repository boundary without manual direction.

  • Automatic repo discovery

    Polygraph indexes every repo you have access to (private and OSS) and builds a relationship graph via packages and APIs.

  • Test and preview downstream

    Test changes and preview their impact on dependent repositories before merging.

  • Unified PRs and CI

    Manage pull requests and continuous integration from one central place.

  • Existing permissions respected

    Works with your current access controls—no extra configuration needed.

  • Session handoff

    Hand off a session across any agent, including repos, branches, PRs, and logs, so context is preserved.

  • Session history

    Reference any past session—Polygraph brings back its description, PRs, and traces for quick debugging.

  • Integrations

    Plugs into your existing stack—connect repos and CI once, and let the agent handle the rest. Integrates with Codex, Claude Code, GitHub, and OpenCode.

Target users

Polygraph is built for engineering teams and developers who work across multiple repositories and need a unified way to manage cross-repo tasks. It's especially useful for teams using AI agents (like Codex, Claude Code, or OpenCode) who want those agents to have full visibility and memory across their entire codebase. The tool is built by the Nx team, so it's likely familiar to developers already using Nx for monorepo management.

How to use Polygraph?

Start by signing up at trypolygraph.com. Once logged in, connect your repositories and CI—Polygraph indexes everything automatically. Then you can prompt your agent with cross-repo tasks, test downstream impacts, and hand off sessions to other agents. For detailed instructions, refer to the documentation available on the site.

Pricing and free trial

Polygraph is free during early access—full product, zero cost. The company gives 30 days' notice before any pricing changes.

Effect review

Polygraph solves a real pain point for teams using AI agents across multiple repositories: visibility and memory. By indexing all repos and building a dependency graph, it eliminates the need to manually tell agents where to look. The session handoff and history features are practical for team collaboration, ensuring context isn't lost between sessions. Since it's free during early access and built by the Nx team, it's a low-risk investment for developers already working with multi-repo setups. The integrations with Codex, Claude Code, GitHub, and OpenCode make it immediately useful for most modern AI-assisted development workflows.
