Spikelog
Log a number via API and get an automatic chart.
Spikelog is a simple metrics tracking tool that lets users log a number via a single API endpoint and automatically generates a chart. It solves the problem of overcomplicated observability setups for tracking basic metrics like job runs or user signups. It is designed for developers, side projects, MVPs, and small production systems. It is positioned as a lightweight alternative to full observability stacks, requiring only an API key and no complex configuration.
