Nabatshy

The observability platform that fits in a single binary.

Live Demo →

Free and open source. Drop in a single executable, point your services at it with OpenTelemetry, and get a full observability UI with traces, metrics, logs, and dashboards. No external database. No infrastructure to manage.

Why Nabatshy

Most observability stacks require running Grafana, Prometheus, and Tempo — or Jaeger backed by Elasticsearch or ClickHouse — before you see a single trace. Nabatshy embeds DuckDB directly into the binary, so the entire platform ships as a single executable with a single .db file on disk.

Designed for production apps with moderate traffic, local development, side projects, and internal tools. Any setup where spinning up a dedicated observability cluster is more overhead than the service it's monitoring. If you need to handle millions of spans per second, use something else. If you want traces working in under a minute, this is for you.

Features

• Trace search and filtering — search by service, operation, duration, and attributes with real-time percentile charts
• Span timeline visualization — flame-graph-style span bars with error highlighting and click-to-inspect
• Service metrics and percentiles — P50/P90/P99 duration charts, error rates, and throughput trends per service and endpoint
• OTel metrics — visualize OTLP metric data points alongside traces
• Log aggregation with full-text search — ingest OTLP logs and search bodies with DuckDB's built-in FTS extension
• Cron-based data retention — schedule SQL queries to delete old spans and keep storage lean

How It Works

When you run the binary, three HTTP servers start concurrently:

Your services send telemetry to http://localhost:4318 using any OpenTelemetry SDK. The collector writes data into a local DuckDB file (nabatshy.db). The UI at http://localhost:8081 lets you search traces, inspect spans, query logs, and view metrics.

Quick Start

Docker (recommended):

docker run -p 4318:4318 -p 3000:3000 -p 8081:8081 -v $(pwd)/data:/data adham99/nabatshy

Build from source:

# 1. Clone and install frontend dependencies
git clone https://github.com/adhamsalama/nabatshy
cd nabatshy

# 2. Build the UI (output gets embedded into the Go binary)
cd ui && npm install && npm run build && cd ..

# 3. Build and run
go build -ldflags="-s -w"
./nabatshy

Then point your OpenTelemetry SDK at http://localhost:4318 and open http://localhost:8081.
