Fey shut down after its acquisition, so I built an open source alternative. Feather is a desktop app for US equity research: live quotes, natural language screener, morning briefs, earnings calendar, watchlists. Runs with zero API keys on mock data.
InstAPI helps connect, explore and query any data source. It enables data analysts and business users to create and share queries as API. Hence, users can automate their workflow with an inbuilt scheduler and third-party integrations. It is our take on liberating the data within the organization to the business users and analysts.
