In their own words
Grafana Loki
Grafana Loki is a free, AGPLv3-licensed log aggregation system for storing and querying application and infrastructure logs. It can be self-hosted on Linux or accessed through Grafana Cloud Logs plans, with API support and live log tailing. Loki scales horizontally, supports high availability and multiple tenants, and indexes labels instead of log-line contents. LogQL provides queries in Grafana or the LogCLI command-line tool. Grafana describes object-storage support for high-throughput, durable, petabyte-scale retention. Loki can evaluate alerting rules on incoming logs and send results to Prometheus Alertmanager, with native integrations for Prometheus, Grafana, and Kubernetes. Documented ingestion options include Grafana Alloy, OpenTelemetry, Kubernetes Monitoring Helm, Docker, Fluent Bit, Fluentd, and Logstash. Installation methods include Helm, Tanka, Docker, Docker Compose, local installation, and source builds. Cloud plans range from free to paid Pro and Enterprise options.
SparkLogs
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.
