Fluxtail

Fluxtail brings application logs into one workspace so developers can search events, follow new activity, and investigate issues without switching between separate log files and tools. It combines centralized log collection, field and time filters, Live Tail, and hosted Model Context Protocol access for compatible AI tools.

The starting point is a searchable view of application events. Teams can narrow the results by time and fields, focus on the part of a system they are investigating, and inspect the matching log entries. This is useful when a question starts broadly and becomes more specific as the developer learns what happened. Saved application context can guide the search, while the logs provide the events that need to be checked.

Live Tail supports the other common workflow: watching events as they arrive. A developer can keep a filtered view open while reproducing a problem or checking what an application does next. Search and Live Tail serve different parts of the same investigation, from reviewing an earlier event to observing current behavior. The product keeps those workflows together rather than requiring a separate interface for each task.

Fluxtail also provides hosted MCP access. MCP is a protocol that lets compatible AI tools work with external services; Fluxtail uses it to make log investigation available from those tools. It is not an AI model, and using MCP does not turn every log entry into an automatic diagnosis. Developers can use a compatible client to ask questions, request relevant searches, and examine the returned evidence as part of their own investigation.

Access through MCP uses account-scoped OAuth credentials that can be revoked. This matters when connecting a development tool to operational information: the connection belongs to a particular account, and the user can withdraw access. The browser product remains available for direct exploration, so an AI-assisted workflow is an additional way to work with logs rather than the only way to use the service.

Fluxtail is built for developers and teams who want a focused place to collect and investigate their application logs. Public documentation explains setup and supported behavior, and the pricing page describes the available paid plans. Starter costs $19 per month and Pro costs $49 per month. New accounts receive a 14-day trial without entering a payment card. There is no permanent free plan.

The trial is a way to evaluate the workflow with an application's own events before choosing a paid plan. It does not include dedicated ports or native sources. When the trial ends, access becomes read-only unless the account moves to a paid plan. Teams should check the current documentation and pricing for the exact setup and limits that apply to their account.
