Diff Anything

What it does

Diff Anything is a private, local-first desktop comparison and merge app for macOS and Windows. It understands text, JSON, YAML, XML, CSV, environment files, folders, archives, documents, API schemas, HTTP responses, images, and binaries. Compared files never leave your computer—there are no accounts, cloud comparison services, analytics, or telemetry. Use semantic diffs, visual comparisons, saved profiles, reports, CLI, and Git workflows to review what actually changed.

A private, local-first desktop comparison and merge application for cross-format spreadsheets, text, structured data, folders, encrypted and multipart archives, documents, API schemas, HTTP responses, images, binaries, and command-line workflows.

Compare the files developers actually work with—not just text. A private, local-first desktop comparison and merge application for cross-format spreadsheets, text, structured data, folders, encrypted and multipart archives, documents, API schemas, HTTP responses, images, binaries, and command-line workflows. Diff Anything chooses a comparison engine that understands the inputs. Spreadsheets compare stored cell values across CSV, TSV, Excel, OpenDocument, and Apple Numbers formats in a sheet-aware grid. Code and text receive language-aware highlighting and moved-block detection, text adds an interactive three-way merge workspace, JSON and other structured formats compare semantic paths, PDFs…from martingruner.com

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
