Fluxtail

Fluxtail gives engineering teams one place to collect, search and investigate application logs. Its hosted Model Context Protocol (MCP) service lets compatible AI tools search logs and work with streams, receivers and sources. Teams can also use the browser interface for filtered log searches and Live Tail.

Shared receivers accept HTTP JSON, OpenTelemetry over HTTP or gRPC, and Prometheus traffic. Paid plans add dedicated receivers for protocols such as Syslog and GELF, plus native sources including Kafka, MQTT and S3/ALB. Accounts keep their logs isolated, and account-scoped access controls determine what users and connected tools can read or change.

Fluxtail is useful when investigating application errors, following activity across services, or bringing log evidence into an AI-assisted development workflow. The web interface remains available for teams that prefer to investigate directly in the browser. Hosted MCP access uses OAuth connections that can be revoked.

New accounts can start with a 14-day trial without a credit card. The trial excludes dedicated ports and native sources and expires into read-only access. Starter and Pro are the paid plans, at $19 and $49 per month respectively. Current prices and limits are published at https://fluxtail.io/pricing. Setup guides and protocol documentation are available at https://docs.fluxtail.io/.
