Fluxtail

Fluxtail is a centralized log management platform that provides log collection, search, and Live Tail capabilities with MCP support for investigating logs through AI tools. It allows users to manage streams, receivers, and sources while integrating with AI assistants like Codex, Claude Code, and Gemini CLI. The service focuses on making live traffic inspection and error diagnosis easier for engineering teams.

New users can start with a 14-day free trial that does not require a credit card. During this trial, access is provided through shared HTTP receivers, while dedicated ports and native sources are reserved for paid plans. Users can create an account and begin sending logs immediately without any upfront cost.

The Starter plan offers 10 GB of stored logs per month with a 30-day retention period, while the Pro plan provides 50 GB per month and extends retention to 90 days. Both plans operate on fixed pricing with no usage overage fees, though hard limits apply that reject new traffic when reached.

Fluxtail integrates with Codex, Claude Code, Gemini CLI, and VS Code with Copilot through a hosted MCP server. These tools can be connected to search centralized logs, explore error patterns, and compare activity over time directly from the chat interface.

Users must first create an account and install the Codex CLI, then run specific commands to add the Fluxtail MCP server URL. After signing in through the browser and approving the intended account, users can ask the AI to verify the connection before using the logs.

The protocol-first ingest method ensures that logs arrive in a structured format, allowing for more reliable parsing and analysis. This approach is part of Fluxtail's focus on creating a clear path from source to readable rows for incident response.

The platform supports native sources including AWS ALB logs pulled from S3, which can be configured via OAuth. These sources start inactive until credentials are entered in the browser settings under the Sources section.

The Starter plan costs $19 USD per month or $190 USD per year, while the Pro plan is priced at $49 USD per month or $490 USD per year. These fixed prices include all features within the plan limits without additional overage charges.

Fluxtail is located in the United States at 651 N Broad St, Suite 201, Middletown, DE 19709. The company operates as a computer software business focused on log management solutions for engineering teams.

Users can reach out to Fluxtail Engineering via the business phone number +13023095270 or by emailing [email protected] for questions regarding accounts, product fit, setup, pricing, legal, or privacy matters.

The core workflow includes live tail, named streams, ingest, and a clear path from source to readable rows. Fluxtail intentionally keeps the product narrower than a full observability suite to focus on these essential components.

When a hard limit is reached, Fluxtail rejects new traffic to maintain system stability. This ensures that existing data remains accessible and the platform does not degrade under excessive load.

Common reasons include account access issues, product questions, setup or ingest questions, pricing inquiries, and legal or privacy requests. The contact page lists these specific categories to help users find the right information quickly.

The platform includes diagnostics features that allow users to check receiver health and get sender setup guidance. Users can also use AI tools to propose a stream named production or summarize errors from the last hour.
