Puppetty

Cross-platform Playwright for terminals, in .NET. Run any CLI or TUI program in a real pseudo-terminal, emulate its screen headlessly, and drive it from tests, scripts or AI agents: type, press keys, click, wait for the screen, assert, snapshot and replay.

  • Emulator: XTerm.NET, a headless xterm-compatible emulator.
  • PTY: Porta.Pty. It uses the bundled ConPTY (OpenConsole) on Windows and openpty on Linux and macOS.
  • Target: net10.0. Tested on Windows and Linux.

using static Puppetty.Testing.Assertions;

await using var term = await Terminal.LaunchAsync("python3", new LaunchOptions { Args = ["-i", "-q"] });
await term.WaitForTextAsync(">>> ");
await term.TypeAsync("print(6*7)");
await term.PressAsync("Enter");
await Expect(term.GetByText("42")).ToBeVisibleAsync();
await Expect(term).ToMatchSnapshotAsync("python-42");

Packages

Package Install What it is
Puppetty.NET dotnet add package Puppetty.NET The library, namespace Puppetty: Terminal, Screen, locators, key/mouse/paste encoding, settling, snapshots, traces. Also auto-retrying Expect(...) assertions and golden snapshots (namespace Puppetty.Testing) for xUnit, NUnit and MSTest.
Puppetty dotnet tool install -g Puppetty The puppetty tool: shell commands with daemon-backed sessions and a live attach view, and puppetty mcp, an MCP server giving AI agents the terminal_* tools.

Docs

  • docs/api.md: the library: launching, input, reading the screen, locators, assertions, settling, snapshots, traces.

  • docs/mcp.md: the MCP server, setup in Claude Code, the annotated screenshot format.

  • docs/cli.md: the puppetty CLI and its daemon.

Build and test

dotnet build Puppetty.slnx
dotnet test Puppetty.slnx

The end-to-end tests drive small fixture apps (tests/fixtures/Puppetty.Fixture). The smoke tests drive real programs (vim, less, top/htop, pwsh, python) and skip any that aren't installed. samples/Puppetty.Samples.XUnit is a small xUnit suite to copy from.
