ClickStack vs SparkLogs

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.

SparkLogs is a cloud-first log management and observability platform for collecting, querying, and retaining telemetry. Its SQL-like, type-aware LQL offers interactive histograms and exploration across billions of events. Data can be sent through the SparkLogs Agent or authenticated Ingest Keys, with ingestion tooling that includes OpenTelemetry, Grafana Alloy, Vector, Fluent Bit, filebeat, Logstash, Beats, and APIs. AutoExtract identifies standard fields in raw messages, while AutoClassify groups similar messages into patterns. The platform also provides live log tailing, pipelines, archive export, and tools for AI-assisted fleet investigations using logs and system state. It supports cloud and self-hosted deployment and runs on web and native desktop and mobile apps. SparkLogs says connections use TLS 1.2 or newer and stored data uses AES-256; it is not yet SOC 2 or ISO 27001 certified. The official agent currently supports Windows 10 or later and Windows Server 2016 or later on x64. SparkLogs Cloud costs $100 a month, with 300 GB monthly ingestion included and a listed free allowance under 25 GB per month. Private Cloud is $440 a month; Self-Hosted Querying is $2,000 a month.
