Diffing Binary Files
My partner reviews a lot of P&IDs (piping and instrumentation diagrams) and the adjacent files involved (excel, docx, pdfs, acd/l5x, etc). In his company, these are usually done in Bluebeam. It's really hard to see the diff + keep track of all the revisions resulted by these iterations. They end up storing files like "rev3_final_redlined.pdf". We've been looking for something close to Github to do these reviews, but haven't found one easy enough for folks with no CLI experience to understand and use (happy to check out more tools if you know any). So I built withkord.com to help with…

In plain words
Diffing Binary Files is a version control tool designed for technical professionals who work with binary files like P&IDs, PDFs, Excel spreadsheets, and CAD documents. It provides a user-friendly alternative to command-line tools like Git, allowing teams to track revisions and view differences between file versions without technical expertise. The tool helps eliminate confusing file naming conventions and streamlines collaborative review processes for engineering and design documents.

Compare two files and see exactly what changed. Visual diffs for PDFs, engineering drawings, Excel/CSV, Word, PowerPoint, 3D STEP models, Rockwell PLC projects, images, and JSON. No login, nothing stored. Powered by Kord.
Twenty-six formats, one tool. Every entry below opens the diff preloaded with a real two-revision sample pair, so you can see how that format reads before dropping your own files in. Yes - no account, no trial clock. The diff playground is the free corner of Kord, version control for engineering document sets; a comparison you can run in ten seconds explains the product better than a brochure. They are kept only as long as it takes to render the comparison. Most formats are read in your browser; Word and PowerPoint are converted to a preview server-side in memory, and a file too large for a request body travels through a short-lived upload that is swept automatically. Nothing is stored, and…from withkord.com

Deff – Side-by-side Git diff review in your terminalFeb 2026 · github.com · ▲120deff is an interactive Rust TUI for reviewing git diffs side-by-side with syntax highlighting and added/deleted line tinting. It supports keyboard/mouse navigation, vim-style motions, in-diff search (/, n, N), per-file reviewed toggles, and both upstream-based and explicit --base/--head comparisons. It can also include uncommitted + untracked files (--include-uncommitted) so you can review your working tree before committing. Would love to get some feedback
I rebuilt the only parts of my IDE I use, in Rust, over a weekendJun 2026 · github.com · ▲50I don't know Rust. Friday after work I realised that 90% of my IDE time now is just the commit/diff view — and even good IDEs feel heavy for that. So over the weekend I built a dedicated native tool for just that. Kyde is a macOS git commit + diff editor with one goal: be fast, do Git well. I'm curious whether anyone else mostly opens their IDE for git operations these days. It's open source, and there's a signed app in Releases.

Codiff, a local diff review toolMay 2026 · github.com · ▲31Nowadays I review a lot of code locally that was written by llms. I used to review my own code using git + delta. It started to feel limiting with the amount of code written by llms. When looking at a large diff on Friday I pointed an llm at diffs.com and trees.software and told it to build an app. It only took 16 minutes, is extremely fast for large diffs, beautiful and minimal. Today I polished it up and added all the features that I need. It has file filters, search, an llm walkthrough mode, and review comments that you can paste back into your llm. I will be using Codiff a lot, and can…

Talanoa▲340Hi 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▲655Hey 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…

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…
