Cisco pyATS vs OpenSpeedTest

Cisco pyATS is a Python framework for network testing, automation, and validation, available free under the Apache 2.0 license. It supports sanity, feature, solution, system, and scale test and verification workflows, with reusable data-driven tests ranging from simple checks to complex asynchronous suites. Genie libraries provide device connectivity, parsers, APIs, platform-agnostic feature models, reusable test cases, and a YAML-driven test runner. Built-in device libraries cover Cisco IOS, IOS XE, IOS XR, NX-OS, and ASA; plugins and extensions can add other platforms. Connections can use CLI, NETCONF, or RESTCONF. XPRESSO manages test suites, environments, testbeds, resources, live test views, and archived results with comparisons and analytics. It supports on-demand, bundled, and scheduled runs through Jenkins and Docker backends. Cisco also documents Ansible community integrations and out-of-the-box RobotFramework support. pyATS runs on Linux and macOS and supports self-hosted deployment. Cisco says more than 75% of its codebase is open source on GitHub. Email support is best-effort and usually receives a reply within a day.

OpenSpeedTest is a free, browser-based HTML5 tool for measuring internet and network performance. It measures sustained download and upload speeds, latency, jitter, and connection stability; the maker says its adaptive test supports connections from 1 Mbps to 10 Gbps and beyond. The browser test runs without an app, plugin, Flash, or Java installation. A responsive widget can be embedded in a website or app. URL parameters can launch a test automatically, run continuous stress tests, choose download, upload, or ping measurements, and set ping samples or parallel connections. For self-hosting, Docker images and source code are available for home, office, cloud, and enterprise environments. The setup guide calls for a public IPv4 or IPv6 address, a domain that resolves to the server, and an email address for Let's Encrypt setup. OpenSpeedTest supports HTTP/1.1, HTTP/2, and HTTP/3. The maker says Firefox is not recommended for stress tests longer than 10 minutes or speeds above 2.5 Gbps. The tool has been available since 2011 and is described for home networks, small offices, enterprise deployments, and infrastructure testing.
