NanoTDB – Golang Append-Only Time Series DB

NanoTDB is a lightweight, single-binary time-series database designed for edge devices and resource-constrained environments like Raspberry Pis, featuring a built-in browser dashboard, editor, and CLI tool without requiring separate services. It uses append-only file storage with compression, achieving approximately 1.3 bytes per data point on disk, and includes built-in rollups, crash recovery, and an offline inspection tool for direct data access. The project targets scenarios where deploying traditional TSDB stacks is impractical, offering integrated observability in under 1 MB daily storage for typical workloads.
