ClickStack vs Kiwi Syslog Server

ClickStack is an open-source observability stack for OpenTelemetry that brings logs, metrics, traces, session replays, and errors into one system. Its HyperDX interface provides Lucene-style search, SQL access, dashboards, alerts, event deltas, and event patterns. A bundled OpenTelemetry Collector handles native collection, while non-OTel wide event data can be used when it has a timestamp field. ClickStack stores data in ClickHouse and is designed for high-cardinality telemetry, with the product site describing sub-second queries even on petabytes of data. It supports self-hosted, hybrid, and cloud deployment. Managed ClickStack runs on ClickHouse Cloud with operations, scaling, upgrades, backups, reliability, authentication, and user management included. The managed offer advertises indefinite retention and storage below one cent per GB. An MCP server connects observability workflows with coding tools, collaboration services, runbooks, and custom agents.

Kiwi Syslog Server is self-hosted software for collecting and managing syslog messages, SNMP traps, and Windows event logs in a central console. It gathers data from network devices and Linux, UNIX, and Windows systems, with filters for hostname, IP address, priority, time, source, and message text. Rules can send email alerts, run scripts, forward messages, or write logs to files or ODBC databases. Its scheduler can archive and clean up logs, including compressing, encrypting, moving, renaming, and deleting them. SolarWinds lists integrations including Loggly, Network Performance Monitor, Papertrail, Security Event Manager, and Splunk. Kiwi Syslog Server NG supports secure TCP syslog using TLS and certificate-based server authentication. The complete trial runs for 14 days without a credit card. The listed Free Edition is free, but SolarWinds currently marks it “Coming Soon”; it is limited to five network devices, a 500 message buffer, and 10 display windows. The Licensed Edition is listed at $999, paid once.
