What is Graph Desktop?

Graph Desktop is a free, local-first API workflow testing tool for Windows and Linux. It lets you design API execution flows visually as connected graphs, run them with full trace capture, and compare runs against saved baselines to detect regressions. No account required.

Is Graph Desktop free?

Yes — Graph Desktop is free forever with no usage limits. There is no paid tier for the desktop product. No sign-up required.

Which operating systems does Graph Desktop support?

Graph Desktop supports Windows (EXE installer, MSI package) and Linux (AppImage, DEB for Debian/Ubuntu, RPM for Fedora/RHEL). macOS support is planned.

How is Graph Desktop different from Postman?

Postman tests individual API endpoints (isolated requests). Graph Desktop tests how your system behaves across a connected workflow — login → fetch profile → place order — with real runtime trace, environment variable chaining, and built-in regression comparison against a saved baseline.

Does Graph Desktop send my data to the cloud?

No. Graph Desktop is local-first — all execution happens on your machine. Your API payloads, credentials, and test results never leave your device. Optional anonymous telemetry can be disabled in settings.

Can Graph Desktop run without an internet connection?

Yes. Graph Desktop runs entirely offline once installed. It tests your APIs directly from your machine with no internet dependency.

What can I import into Graph Desktop?

Graph Desktop can import OpenAPI (Swagger) specifications and Postman collections to automatically generate test graphs. You can also import existing Graph DSL packages in YAML or JSON format.

Does Graph Desktop work in CI/CD pipelines?

Yes. Graph Desktop includes a CLI mode for executing graphs from the command line, suitable for GitHub Actions, GitLab CI, Jenkins, and similar pipelines.

Graph Desktop — Free API Workflow Testing Tool for Windows & Linux

Graph Desktop is a free, local-first API testing tool. Design, execute, and validate API workflows visually using a graph canvas. No account required — your data never leaves your device.

Key Features

Visual Graph Studio: Model API execution flows with drag-and-drop nodes and edges on a canvas. Each edge carries labels, variable mappings, retry rules, sleep, and assertions.
Local-First & Free: Runs entirely on your machine — no sign-up, no cloud sync, your data never leaves your device. Free forever.
Baseline & Regression Detection: Compare runs against saved baselines to detect status changes, latency drift, and payload regressions automatically.
Forensic Run Inspector: Node-level trace with request, response, validation issues, and raw IO snapshot. Sensitive values are masked.
Schema Lifecycle: Versioned schema store for request and response shapes, with XPath evaluation and XSD validation.
Import & Portability: Import from OpenAPI specs or Postman collections. Export graphs as YAML or JSON DSL packages.
CLI & CI/CD: Automate graph execution from the command line for pipeline integration.
Execution Reports: Technical HTML and executive summary reports for every run.

Graph Desktop vs Postman, Bruno, and Insomnia

Postman, Bruno, and Insomnia are all request-first tools — you build and run isolated HTTP calls. Graph Desktop is workflow-first — you model how your whole system behaves across a connected sequence of API calls.

Unlike Postman or Insomnia, Graph Desktop requires no account, no cloud sync, and no subscription. Unlike Bruno, it adds built-in baseline regression detection, a forensic run inspector, and executive reporting — not just local file-based collections.

End-to-end API workflows, not isolated calls (Postman/Bruno/Insomnia alternative)
Visual graph execution and flow control
Built-in regression detection via baseline compare — no scripting needed
Forensic run inspector with per-node trace and masked secrets
Environment-driven variable chaining across the full graph
CLI-ready for GitHub Actions, GitLab CI, and Jenkins
Schema validation and contract drift detection
100% local — no account, no cloud, no subscription
