Show HN: Codiff, a local diff review tool

Sun, 05/17/2026 - 1:30am

Nowadays 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 finally review the large diff from Friday that led me to build this If you like it, fork it!

My indie app was named too close to competitors and I burnt my fingers

Sun, 05/17/2026 - 12:59am

I am an indie developer building a chrome extension for Gmail.

I was a heavy user of Superhuman (the email app) for a few years and found it too expensive. So, I built a chrome extension to replicate its behaviour within Gmail. I named it Simplehuman, because a simpler version of the same experience.

It was all good for a few years until last month Superhuman reached out over a potential trademark infringement. They were surprisingly nice about it. But then another home appliance company with the same name also sent me a similar notice.

While my legal counsel advised I had a case to continue with the same name, I would rather invest the money in building the business than pay lawyers on both ends.

So I renamed it to CMDK - the hotkey that brings up the command bar in most apps.

But this is what really happened right after the rebrand and URL changes. An 80% drop in organic traffic and a huge rebranding effort that took weeks. As a solo indie dev, this could have been time spent on growth on building the product.

Lesson learnt: to be careful not to name your products too close to established products. They will come at you, you can't time the when, and its a massive distraction and waste of time.

Ask HN: What LLM models are you using and why?

Sun, 05/17/2026 - 12:57am

Hello, HN!

I'm wondering what y'all are using for your daily driver these days and why?

I've found myself using GPT-5.5 more than Opus 4.7 for work; which, has been a pretty big reversal. Previously, I was using Opus 4.6 for everything, and GPT-5.4 was only ever in the picture to provide a second opinion (with Grok a distant 3rd only when I wanted to throw some "chaos" into the mix). The reason I've personally pivoted, is I've found GPT-5.5 to be a bit more consistent, predictable, and tends to write in a way I find less tiresome (even if the code isn't quite as good as Opus 4.7).

For personal projects, I've started experimenting with DeepSeek V4 and have been pretty blown away by it because of it's cost to quality and I've found the 1M token window to be incredibly helpful for long-running tasks. Though I may also have an over abundance of fear of compaction during tasks. DeepSeek isn't quite as good at one-shotting things as either GPT-5.5 or Opus-4.7, but with sufficient linter/static-analysis guardrails I've found it's really hard to complain or find faults (especially at the price).

Finally, if you're also making use of reranking and/or embedding models, or anything else, to augment or perform specific tasks please share those too!

Ask HN: Why do hotels etc. WiFi networks all use captive portals?

Sun, 05/17/2026 - 12:55am

Many of them don't require any kind of authentication, just clicking a button.

Is it just a case of "monkey see monkey do" (decision makers see it everywhere, so they also want it), do lawyers really think that giving people pages full of "you must not use this wifi to break the law" T&Cs is necessary, or does it serve an actual technical purpose like soft-disconnecting devices after N hours to minimize background traffic or keeping noisy IoT devices from blindly connecting to the open WiFi?

What right has a "personal fortune" to be anything but working capital?

Sun, 05/17/2026 - 12:53am

What right has a "personal fortune" to be anything but working capital? The time is here when the commanding law is, "to whom much is given, of him shall much be required."

Show HN: Machine – One VM per Project

Sun, 05/17/2026 - 12:49am

Hi all!

I realized it’s really not secure to run coding projects directly on my Mac. All the NPM hacks recently, especially with agentic coding — you’re always one npm install away from a disaster.

So I’ve built a small CLI called machine that starts a Lima VM for each of your projects. It supports declarative “profiles” which are like package.json for your VM. The default profile comes with standard stuff like Node.js, git, Docker, Claude Code and Codex.

If you share your projects.toml with your team, every developer can spin up your team’s entire dev environment with one command. No need to install dev tools, clone repos, npm install anything manually.

Another cool thing is that you can use the native MacOS keychain or 1password to forward SSH signatures to the VM. So every time you need to commit or push code, you touch the Touch ID key and it’s signed. SSH keys never leave the host.

The same is done for env variables and secrets. You inject them with one command from 1password when the machine starts and they are never stored in a file.

Genuinely curious about your feedback!
