IT teams, MSPs, and network engineers use Obkio to gain complete visibility into network performance, whether it's happening in the office, across a hybrid workforce, or in the cloud. Obkio is a Network Performance Monitoring (NPM), observability, and diagnostics platform that works by deploying lightweight monitoring agents at any location, with no special hardware required. These agents continuously measure latency, jitter, packet loss, and bandwidth, while running Visual Traceroutes to map performance across the full network path. The platform covers SD-WAN, MPLS, and VoIP/UC monitoring, along with visibility into multi-site and distributed networks. Application performance monitoring (APM) rounds out the picture with HTTP, Web, and Teams-based synthetic tests. A standout feature, Obkio Insight, automates root-cause diagnostics, quickly showing whether a problem sits within the internal network, with an ISP, or with a third-party provider, backed by concrete performance data. Because it deploys in minutes, Obkio gives teams fast answers instead of raw data to sift through. The result: less time troubleshooting, stronger SLA validation, and clear proof of whether the network performance they're paying for matches what they're actually getting.

Most web performance issues don't show up at one user... they show up at hundreds or thousands of users. Loadster is a cloud platform for simulating that kind of traffic and then seeing how your web application responds to it. Loadster has Browser Bots and Playwright for real browser testing, or Protocol Bots for lightweight HTTP protocol testing. Load test scenarios mix bot types, ramp populations up over time, and run load tests with hundreds or thousands of concurrent bots from cloud regions of your choice. The built-in reporting covers response time distributions, error rates, page-rendering metrics, and detailed traces about individual user journeys. Loadster also has built-in 24/7 site and API monitoring. Loadster monitoring reuses the exact same scripts as synthetic checks running 24/7 from selected regions, with alerting through Slack, PagerDuty, SMS, or voice robocall whenever something goes wrong. Maintenance windows mute monitors during planned work so on-call pagers don't fire for non-events. The free tier is 50 units of Loadster Fuel with no credit card required (enough to run a few load tests or maybe several weeks/months of monitoring). Usage scales from one-off load tests up to continuous testing and monitoring plans.
