darold/pgbadger
It reads PostgreSQL's own log file and produces one HTML page naming the slowest queries, in order.
electric-sql/pglite
The real PostgreSQL engine compiled to WebAssembly, so it runs inside a JavaScript program or a browser tab with no server at all.
rilldata/rill 💎 hidden gem
Dashboards defined in small files, running on your own machine.
pola-rs/polars
A Rust-based dataframe library with a Python interface — multi-core, lazy, and able to work through files larger than memory.
timescale/timescaledb
A PostgreSQL extension for time-series data — automatic time chunking, compression of old chunks, and continuous aggregates.
unionai-oss/pandera
Schema validation for DataFrames — the error that fires before a backtest quietly reports a fictional edge.
perspective-dev/perspective
WebAssembly data grid and charts for large or streaming datasets — pivot two hundred thousand trades in the browser.
posit-dev/great-tables 💎 hidden gem
Display tables in Python with titles, spanners, footnotes and real number formatting — from a pandas or Polars frame.
smithyhq/sqladmin 💎 hidden gem
A SQLAlchemy admin panel mounted inside the FastAPI app he already runs — support without a psql prompt.
duckdb/duckdb
SQL over three years of EURUSD bars in a file, with no server and no import step.
paradedb/paradedb
BM25 and full-text search that live inside Postgres, not in a separate Elasticsearch cluster that also needs backups.
simonw/datasette
sqlite-utils fills the database. Datasette lets you (or, if you point it at the world, anyone) browse and query it.
evidence-dev/evidence
Business intelligence as Markdown files with SQL in them, building to a static site — a dashboard Claude Code can write.
simonw/sqlite-utils 💎 hidden gem
Pours JSON and CSV into a real SQLite database with no schema design, then indexes it and adds full-text search.
marimo-team/marimo
Reactive Python notebook stored as a plain .py file — no hidden execution order, and `marimo run` serves it as a web app.
pgvector/pgvector
Vector search as an ordinary SQL query inside the Postgres he already runs. No new server, no new backup story.
