Overmonitor is a cloud-based infrastructure, website, and endpoint monitoring platform built for fast setup without enterprise complexity. Monitor websites, APIs, servers, processes, Windows services, event logs, performance counters, SNMP data, uptime, response time, DNS, SSL certificates, internal endpoints, and network health from one dashboard. The lightweight 2.1 MB agent runs as an idle process, requires no inbound firewall exceptions or open ports, and sends a secure heartbeat every minute. Configure monitoring quickly through the web interface and target checks by city-level geography. Maintenance windows suppress expected noise, while configurable alerts, push notifications, and audible dashboards keep the right people informed. Multi-location endpoint checks validate incidents, reduce false alarms, expose regional problems, and reveal how availability and responsiveness differ across target markets. Distributed Monitors expand Overmonitor’s network by allowing eligible servers to opt in and check up to 10 external endpoints. Checks add negligible data to the existing heartbeat, require no extra configuration or firewall changes, execute no remote web scripts, and store no monitored data on the server. If a participating server or network becomes unavailable, its checks are automatically reassigned. Participation also earns prorated invoice credits. Trend Analysis turns historical infrastructure metrics into proactive capacity planning. Choose from thousands of performance counters, including CPU utilization, available memory, and disk space, then assign minimum and maximum thresholds. Once enough data has been collected, Overmonitor applies linear regression to estimate when a metric may cross its limits. A configurable planning horizon controls when responsible team members are alerted, helping you rebalance workloads, tune resources, or scale capacity before performance becomes an outage or unbudgeted emergency. Trend Analysis is included with every server metric at no additional charge. Overmonitor also includes process rollups, embeddable performance graphs, endpoint health visibility, flexible retention, multiple users with roles, and à la carte pricing so you pay only for the monitoring you need. Detect outages, correlate website symptoms with server health, analyze performance, track availability, and improve end-user experience before small issues become downtime.

RouteGenie is NEMT software built for non-emergency medical transportation operations that have outgrown basic dispatch software. It combines NEMT scheduling software, dispatch, routing, billing and fleet compliance in one platform, running 600+ fleets and 20,000+ vehicles across 46 states and two countries at roughly 50,000 trips a day. NEMT dispatch software built for multi-site scale. Operators run every location in one instance with role-based access, per-location configuration and a complete audit trail on every trip change — who cancelled a trip, when, and why. DispatchGenie builds and continuously re-optimizes routes with native multiload, so a 200-vehicle schedule rebuilds in seconds instead of being maintained by hand. Subcontractor vehicles appear on the same live map as owned fleet, which matters when your network is larger than your payroll. NEMT broker software, built in. ImportGenie runs 28 live broker and payer integrations — ModivCare, MTM, Veyo, Verida, SafeRide Health, Alivi, VectorCare, New York MAS, Uber Health, transit authorities and Medicaid health plans — importing trips and returning statuses automatically, with no re-keying. BillingGenie is full non-emergency medical transportation billing software: Medicaid billing, CMS 1500, broker billing, claim scrubbing and denial management in the same system, so billing is not a second platform. Enterprise administration. SAML2 single sign-on with Microsoft Entra ID, Okta, OneLogin and Google Workspace. Single-tenant deployment with per-customer data isolation. SOC 2 Type 1 attested. HIPAA-aligned controls, BAAs, encryption in transit and at rest, role-based permissions, and four portals: staff, drivers, payers and facilities, and passengers. Open REST API. Pricing that does not punish growth. Flat per-vehicle pricing with unlimited trips and unlimited users. No per-trip fees, no per-seat licensing. Cost tracks your fleet, not your trip volume or headcount — which is why high-volume operators and large agencies model lower total cost here than on per-trip or per-user platforms. RouteGenie serves large and mid-size NEMT providers, PACE organizations, adult day programs, regional transit authorities, brokers and Medicaid health plans. Providers running 80 to 170 vehicles have migrated here from legacy paratransit and NEMT platforms. No fleet minimum. 4.6/5 across 49 reviews. 13 consecutive SourceForge Top Performer awards.
