Hey Product Hunt 👋 I'm Abhijeet, and QueryFlow is my side project. I write SQL most days, and two things kept eating my time. Someone would send me a CSV and I just wanted to run a query on it. Or I'd inherit a 1,000-line query where changing one date meant hunting for it all over the file. QueryFlow is the tool I wanted for both. It's a SQL editor that runs entirely in your browser. You can: - Drop in a CSV or Excel file and query it as a table straight away. It handles files up to 500 MB and never uploads them. - Paste a big query and see how its tables and CTEs join, as a graph or as steps in plain English. - See every date, filter value and variable in one panel, and change one there to update the SQL. - Get warnings for bugs that don't throw errors, like a WHERE clause that turns your LEFT JOIN into an INNER JOIN. - Hover, jump to a definition, find uses and rename, the way you would in a code editor. It reads BigQuery, PostgreSQL, MySQL and SQL Server, and runs queries locally with DuckDB compiled to WebAssembly. There's no login or server, it doesn't use AI, and it's free and open source (MIT). What would make you reach for this instead of a spreadsheet or your usual SQL tool? I'm around all day to answer questions.

What's the biggest challenege in existing SQL editors?

I'm launching QueryFlow here on Saturday. It's a browser-based SQL editor for reading long queries and running SQL on CSV files. Before launch, I'd like to hear what frustrates you in the editors you use now. Is it reading someone else's long query, tracking down where a value is set, setting up a connection just to query a file, or something else?
