Data Diff – compare tables of any size across databases▲127
Gleb, Alex, Erez and Simon here – we are building an open-source tool for comparing data within and across databases at any scale.

As a company, Datafold builds tools for data engineers to automate the most tedious and error-prone tasks falling through the cracks of the modern data stack, such as data testing and lineage. We launched two years ago with a tool for regression-testing changes to ETL code…

Comparelists.org – Instantly Compare Two Lists, Find Differences▲10
Hey HN, I got tired of manually comparing two lists (think: emails, product SKUs, code, whatever) and built CompareLists.org to make it painless. You just paste your two lists, hit compare, and instantly see what’s unique to each list, what matches, and any duplicates. It handles thousands of lines, works right in your browser (no data leaves your device), and you can export results as CSV/TXT/JSON. There are options for case sensitivity, whitespace, and more. It’s free and there’s no signup. I’d love for you to try it out and let me know what you think—or if there’s a feature you…

Docfd: TUI multiline fuzzy document finder▲44
Think interactive grep for text files, PDFs, DOCXs, etc, but word/token based instead of regex and line based, so you can search across lines easily. Docfd aims to provide good UX via integration with common text editors and PDF viewers, so you can jump directly to a search result with a single key press. --- I originally wrote this tool to help me dig through text/markdown notes, since very often I want to search for a phrase of sorts that may span across multiple lines, but constructing the corresponding multiline regex is a bit painful (especially painful if I want to account…
