About Probe

Construct, test, and automate API workflows across HTTP, GraphQL, and WebSocket protocols. Built with Rust and GPUI for fast native performance, it keeps collections as local YAML files that integrate into Git repositories. It includes response tools for decoding JWT headers, converting timestamps, and storing sensitive API keys directly inside operating system credential managers without mandatory cloud accounts.

Who is Probe for?

Software engineers, QA testers, and automation teams who previously relied on heavy desktop clients that required online workspaces, forced cloud accounts, and background telemetry. It fits developers who want to manage API test suites locally alongside AI agents and automated scripts.

How does Probe work?

Build request collections directly inside the desktop app or import existing client files. Save and commit OpenCollection YAML files into your Git repository with localized environment variables. Execute requests headlessly through the CLI inside shell scripts, automated CI test pipelines, and AI agent workflows.
