Instead of writing separate connection logic for PostgreSQL, Redis, Salesforce, and other sources, you define a single QS object with your query and output format, then await the result. It uses the proxy design pattern to route queries to the appropriate backend handler.\n\nThe library carries substantial dependency weight\u201465 runtime packages including database drivers (psycopg2-binary, sqlalchemy), web automation tools (selenium, playwright), API clients (hubspot-api-client, simple_salesforce), and async utilities. This breadth reflects its goal to support many data sources out of the box, but means you inherit all those dependencies even if you only use a subset of backends. It targets Python 3.10.1 and above, is actively maintained (last commit 2026-08-07), and carries no known vulnerabilities.","worth_installing":"Yes, if you need to query multiple heterogeneous data sources (databases and APIs) in an async context and can absorb the 65-dependency footprint. The active maintenance, recent release, permissive license, and zero known vulnerabilities support adoption. No, if you only need a single database driver or want a minimal dependency footprint\u2014the proxy abstraction is not worth the overhead for single-source use cases."},"id":"querysource","links":{"html":"https://skillfed.io/packages/querysource","md":"https://skillfed.io/packages/querysource.md","pypi":"https://pypi.org/project/querysource/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-05","license_spdx":null,"license_treatment":"permissive","name":"querysource","python_support":"supports_current","summary":"Aiohttp web service for querying several databases easily"},"popularity":{"monthly_downloads":110264,"position":12477,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"4.5.11"}
