Redash
Open-source query and dashboard tool for querying multiple databases and visualizing results, similar in spirit to Metabase but query-first rather than click-driven. Maintenance has slowed since its acquisition by Databricks.

⚙ Full Stack
Python (Flask) backend with a React frontend, Postgres for its own metadata store, Redis for caching/queues, and Celery workers for executing scheduled queries against connected data sources.
📈 Scaling Analysis
Query execution scales by adding more Celery workers independently of the web tier, which is a solid pattern, but slowed upstream maintenance means newer scaling patterns (e.g. Kubernetes-native worker autoscaling) aren't well documented or tested by the project itself.
🚀 Running on Nexlayer
Requires app, worker (celery), postgres, and redis pods — a genuinely multi-service topology on Nexlayer, with the app reaching redis.pod:6379 and postgres.pod:5432. Mirror the Python base image via mirror.gcr.io and budget time for wiring Celery's broker/backend URLs correctly.
