LibreSpeed vs Ostinato

LibreSpeed is a lightweight JavaScript speed test that uses XMLHttpRequest and Web Workers to measure download, upload, ping, and jitter. It supports IE11, current Edge, Chrome, Firefox, Safari, and mobile browser versions. Telemetry and result sharing are optional, and an installation with multiple test points can automatically select the point with the lowest ping. A separate stability test reports current, average, minimum, and maximum latency, jitter, failed-request percentage, threshold alerts, and CSV export. It can target a local backend, configured test points, or Google, Cloudflare, and Apple. Deployment uses a web server such as Apache, nginx, or IIS with PHP 5.4 or newer, though other backends are available. Optional result storage supports MariaDB, MySQL, Microsoft SQL Server, PostgreSQL, and SQLite. The project provides an Android client template, a command-line client, and a .NET client library through NuGet. Go and Rust implementations are available; the Node.js implementation is partial and not recommended. LibreSpeed is free and open source, with self-hosting and no paid plans listed.

Ostinato generates and customizes network traffic, or replays PCAP files, to help validate throughput, QoS, multicast, routing, switching, protocol behavior, and network performance. Users can edit supported protocol headers, set frame sizes, and create custom headers with hexdumps or scripts. PCAP replay can preserve or alter packet timing, loop traffic, or reorder packets. Native protocols include Ethernet, VLAN, QinQ, IPv4/IPv6, UDP, stateless TCP, ICMP, ARP/NDP, IGMP/MLD, and GRE; other methods can support headers such as MPLS and VXLAN. Reports show transmit and receive statistics, per-stream packet loss, and latency and jitter measured with software timestamps. A Python API supports stream and scenario creation, run control, counter collection, and CI/CD integration. Ostinato lists GNS3, EVE-NG, Cisco CML, and Containerlab as supported lab environments, and says it works on AWS and Azure cloud VMs. It runs on Linux, macOS, Windows, and self-hosted or API setups. Plans start at $12 a month billed annually; an active subscription is required.
