iPerf2 vs Netpicker

iPerf2 measures network traffic performance, including throughput, latency, link capacity, and responsiveness. Testing uses a client to send traffic to a server. It can generate TCP and UDP traffic in one-way, bidirectional, full-duplex, and simultaneous multi-stream configurations. Measurements include one-way delay, round-trip time, jitter, packet loss, and throughput. It supports IPv4, IPv6, and multicast, including source-specific multicast joins, and reports can include enhanced metrics or use CSV format. The project manual describes an Android client with live meters for throughput, latency, and congestion signals. The manual also describes permit-key HMAC authentication using a timestamped HMAC-SHA256 value, with replay limited by a configurable time window. Its Professional feature set includes server access gating and remotely enabled server-side latency histograms. Measurements happen at socket-level reads and writes, so lower-level protocol-header overhead is excluded. iPerf2 and iPerf3 are separate implementations and do not interoperate. It runs on Android, Linux, macOS, and Windows, and can be self-hosted. Both listed editions are free.

Netpicker validates network state, device configurations, compliance, security and behavior, and can automate remediation. It runs automated Python tests in pytest format against device configurations, show-command output and API data. The free version includes unlimited configuration backups, Git history, diffs, search and drift detection. Netpicker supports devices from more than 180 vendors and can be deployed as a Docker container or OVA virtual appliance, on-premises or in air-gapped environments. API-based connections link it to source-of-truth systems, Git, ITSM tools and other existing tools. Its REST API manages devices, backups and tests, runs show commands and tests, and restores backups; documentation is provided through Swagger/OpenAPI. Security validation covers CVEs, security configurations, compliance and pen-test findings without sending network data outside the customer's environment. Potential CVEs are matched by OS version, while verified CVEs also check whether vulnerable features are enabled and mitigations are present. AI can draft tests, remediation jobs and troubleshooting queries from plain English, subject to engineer review and approval. The free Foundation plan is available; Professional starts at $7,500 a year.
