KaretSelf-hostable analytics platform

Ingest CSVs, build pipelines, and chart the results in configurable dashboards.

Four small services

A Next.js web UI, a Rust/Axum worker, an S3-compatible object store, and a Valkey job queue. No database server, every byte of durable state lives in the buckets.

SQL-driven dashboards

Every panel is a DuckDB query in a YAML config, edited in-app with autocomplete and inline validation. Click a chart to filter the rest.

Auto-runs on upload

Drop a CSV into the bucket and a webhook kicks off a debounced pipeline run.

Single-admin auth

Password-only login, scrypt-hashed at OWASP cost. No user table to manage.
