Datadog
datadoghq.com
Infrastructure metrics, APM, logs, synthetics and security monitoring in one platform. Powerful, and famously easy to overspend on.
Fluxtail
fluxtail.io
Centralized log management for engineering teams. Logs arrive through authenticated receivers, with shared HTTP JSON ingest during the trial; paid plans add dedicated ports and native sources. Logs are organised into named streams, searched, watched in Live Tail and used for alerts. A hosted MCP server lets Codex, Claude Code, Gemini CLI or VS Code with Copilot search logs, diagnose missing ones and propose changes to streams, receivers and sources, applied only after you confirm, through OAuth access to one account that you can revoke. Starter ($19 a month or $190 a year) stores 10 GB of logs a month with 30-day retention; Pro ($49 a month or $490 a year) stores 50 GB with 90-day retention. Prices are fixed with no overage fees, and new traffic is rejected at a plan's hard limit. The 14-day trial needs no card.
