Our verdict on Probe
Probe is a desktop HTTP/HTTPS debugging proxy for macOS and Windows. It captures traffic from computers, phones, and other devices on a local network, giving developers, backend engineers, and QA teams tools to inspect and modify requests and responses. Its scope covers HTTPS interception, request composition, traffic sessions, replay, response mocking, network throttling, WebSocket capture, and upstream proxy chaining. The product is particularly suited to teams that want scripted workflows across desktop and mobile traffic rather than a browser-only debugging utility.
The published plans show a Free option priced at $0 USD as a one-time amount, with HTTPS interception, mobile device debugging, request and response inspection, breakpoints, JavaScript scripting, request collections, and session save, load, and export. The Pro plan adds advanced scripting and automation, Map Remote, Map Local, team collection sharing, and priority support; its listed price is TBD. That structure makes the free tier a meaningful starting point for individual debugging, while teams that need shared collections or expanded automation have a defined upgrade path.
Probe’s standout depth is its combination of editable traffic and controlled reproduction. Breakpoints can pause and edit requests or responses, scripts can modify them, Map Local can mock responses from inline bodies or local files, and Map Remote can rewrite upstream URLs. Global and scoped throttling rules, WebSocket tools, and saved sessions extend that workflow beyond basic request inspection. Integrations with MCP, Claude Code, Cursor, cURL, and Postman support existing development workflows. Choose Probe for desktop and mobile traffic analysis with scripting and replay; choose an alternative if you need broader platform coverage or a published Pro price before committing.
