What Fluxtail is
Fluxtail is a paid, cloud-deployed log management service for engineering teams, available through web and API access. It accepts logs over HTTP, Syslog, OTLP/OpenTelemetry, GELF, Kubernetes agents, Fluent Bit, rsyslog/syslog-ng, and client libraries for Go, Python, PHP, NestJS, Node.js, Java, Rust, and .NET. Workflows include pipelines, live tailing, structured parsing, stream filters, facets, histograms, historical windows, and bounded rendering for noisy bursts. Diagnostics provide usage and quota alerts, receiver health checks, exception search, error summaries, and no-log checks. Built-in AI chat and an MCP server can query logs from compatible AI tools. Data is isolated by account, with scoped access tokens and OAuth-bound hosted MCP connections. Starter costs $19 a month, billed monthly, with 10 GB stored logs, 3 dedicated ports, 2 native sources, and 30-day retention. Pro costs $49 a month, billed monthly, with 50 GB, 10 dedicated ports, 10 native sources, and 90-day retention. Fluxtail states that plan charges have no usage overage fees.
