[OS]CodeBurn: a free, open-source Mac app that shows what your AI coding tools cost and finds the waste

Hey! I made CodeBurn because my AI bill kept going up and I couldn't tell why. Then I found out a good part of it was paying for nothing. CodeBurn is a free, open-source Mac app that does two things. It shows where your AI coding money goes, and it finds the tokens you're burning without getting anything back. It reads the session files that Claude Code, Codex, Cursor, Copilot, Gemini CLI and about 35 other tools already save on your disk, and breaks your spend down by project, model, git branch and task. Today's spend sits in the menu bar next to the clock. The Capacity Dock is a thin strip on the edge of your screen with one ring per provider, so you see your 5-hour and weekly limits filling up before a long run instead of after it. **OPTIMIZE** This is the part I use most. Optimize goes through your Claude Code sessions and setup and lists what costs tokens without earning them: \- MCP servers you installed months ago and never call, but still pay for on every request \- A [CLAUDE.md](http://CLAUDE.md) that grew so long it's sent along with every message \- Files the agent re-reads over and over in the same session \- Skills, agents and commands you never use \- Sessions that read build folders or retry the same turn again and again Each finding comes with a grade, the fix, and an estimate of what it saves. For config problems CodeBurn can apply the fix for you. It shows you the exact change first, backs up every file, and undoes it with one command. A few days later it ch

Inkstone: Markdown editor for your every markdown file. Spaces, splits, plain files [Giveaway: Lifetime Promo Codes]

Hi r/macapps 👋, I've been building a Markdown editor since February because I had two problems with every editor I tried, and no app fixed both. One: the text jumps when you click into markup, breaking the flow. Obsidian expands the line to source, iA Writer shows the markup all the time, Typora is great but I yearn for greater file management features, wikilinks and a more native UI. Two: I never work in one folder. My markdowns are in projects' docs, in knowledge bases, in blogs, in reading notes, in claude code skills and memories, and every editor makes that a window per vault or a folder per window. I love Arc browser’s spaces feature, and I want that to be made into a markdown editor. **Problem:** Two, and no editor fixes both. Markdown editors either show you the markup or move the text around when you click into it, and either way the flow breaks; the ones that does WYSIWYG either lacks link features or lock your notes in a database. And if your markdown files live in more than one folder, there’s no other tool on the market that handles multiple projects with powerful layout system and smooth context switch. So Inkstone does both. It renders WYSIWYG Markdown as you type. Click a heading, nothing reflows. A link's address opens in a popover instead of unfolding inline, no visual clutter. And a space holds multiple root folders in sidebar. You can add multiple folders to spaces from anywhere on your Mac. Tabs and splits layout belongs to the space, so switching from w

devglow update: workspaces, agents that lay out their own panes, and Windows

I posted devglow here about six months ago (v1.4). It’s on v1.9 now, so here’s what changed. **\[Problem\]** AI writes a lot of code now, but someone still has to start the servers and read the logs. Anyone building something, developer or not, ends up with a set of commands they run every day: npm run dev, flutter run, docker compose up. devglow keeps them in one place so you can start, stop, or restart each one with a single key. It also has an MCP server, so Claude Code, Cursor, and Codex can do the same and read the logs. **Changes since then:** Running several projects meant setting up the panes again each time. Now you can group them into workspaces and save layouts by name. ⌘1-9 switches between them. When an agent started a few processes, they only showed up in the sidebar. Now the agent can open a new workspace with all of them on screen (MCP workspace\_run). flutter run worked, but hot reload meant switching to a terminal. Now r / R work in the pane. Light themes. It was dark only before. Windows support. It was macOS only before. **\[Comparison\]** tmux, herdr, cmux, and Orca are Swiss Army knives, and good ones. They’re built around interaction: talking to an agent, typing into a REPL, working over ssh. devglow does one thing. It’s for processes you don’t need to interact with but want to keep an eye on, like next dev, vite, and cargo watch. I also use it for kubectl logs -f on pods. You can see what’s running and which port it’s on. If a port is already taken, de

Parall.app - run multiple instances of Mac apps natively with separate accounts

I created [Parall](https://parall.app) to let you run multiple instances of the same Mac app as though each were a separate app. **Parall is the first app of its kind to solve this without copying the original app, damaging its signature, or downgrading its security.** Each Parall shortcut launches the original, unmodified installed app with its own identity and configuration. # What's new The recent update fixes several things that make a difference in everyday use: * **Compatibility with third-party Docks and Cmd+Tab is fixed.** * **Opening links in browsers is now instant.** * **Bringing minimized apps to the front from Raycast or Spotlight now works correctly.** * **Complete support of Firefox-based browsers and apps on macOS 27 Golden Gate.** *To get the latest Parall launcher features and fixes, you need to edit or regenerate your existing Parall shortcuts. Shortcuts do not update automatically yet.* The philosophy behind Parall remains the same: you should control how many app instances you run and where each one stores its data. You can run separate Chrome, Claude, Discord, or Slack instances, assign each a custom data path, give each its own Dock icon, add Dock animation effects, and force Light or Dark appearance independently of your system setting. Many apps have already been tested and confirmed compatible. You can find the results on the [Parall compatibility page](https://parall.app/compatibility). Most unsandboxed Mac apps are also fully compatible without nee

Ask HN: Do you offload your coding to AI, or keep your skills sharp?

I used to be a software engineer, but these days I find myself being more of an agents manager: constantly switching between 3-4 tasks that my agents are working on, and making sure that the features get shipped, the bugs fixed, with correct and clean code. There's no doubt that I'm producing more value for the company, but I wonder if that's the best I can do for myself if the goal is staying relevant in the coming years. I wonder: if the AI is writing all the code, what value am I bringing? In an attempt to keep my critical thinking and coding skills sharp, I sometimes foolishly try to debug errors or implement a feature myself. But it feels like wasting time when an agent can do it in a fraction of time. What is gonna be sought after in the coming years: someone that persevered with manual coding and debugging but is slow and uncomfortable around agents, or someone that has little coding and debugging skills left but knows how to orchestrate dozens of agents effectively? I'm curious to hear what other software engineers on HN's approach is.

Ask HN: Why so many dead comments lately?

I've noticed a lot more dead comments lately in cases where the person is writing reasonable comments. You'll need showdead turned on in your settings to see the examples. Take this thread as an example https://news.ycombinator.com/item?id=49818698 The OP has a new account but all his replies are within the guidelines. Here's another account with a dead comment in that thread. Most of their comments, while brief, seem perfectly reasonable.

FMail3 a Mac application for Fastmail

The application is for people who use Fastmail and would rather have it feel like a proper Mac app than just another browser tab. It’s basically Fastmail in a native WKWebView, with a bunch of Mac-specific stuff added around it: * Dock/menu bar unread counts + notifications * Proper macOS windows and tabs, persistent window/tab state * Separate compose window * Unread mail updated in real time via Fastmail's JMAP push connection. No polling delay. * Can be set as the default email client for mailto: linksPDF export * Attachment browsing * Quick masked-address creation * Persistent text highlights * Hookmark/Linker support * Use large attachments via Fastmail Files * Optional custom CSS/JavaScript * Auto-hide & focus * No Electron It’s free, notarized, and currently requires macOS 15+. There are a few WKWebView-related limitations (for example, some passkey/YubiKey authentication scenarios), so it’s definitely not trying to replace every Fastmail workflow. I originally made it (in 2019) because I wanted something more Mac-like for Fastmail, and figured other Fastmail users might find it useful too. Website: [fmail3.appmac.fr](http://fmail3.appmac.fr) If anyone here uses Fastmail on Mac, I’d be curious to hear what you currently use and what you’d want from a dedicated Fastmail app.

Trace 2.0: native Mac storage analyzer + uninstaller. No telemetry, no Electron, no subscription, no bullshit.

I released Trace earlier this year and posted about it here around launch. Over the last nine months I've put a lot more work into it, particularly into speed, accuracy and handling Macs with very large drives or huge numbers of files. Storage analysis on macOS gets complicated surprisingly quickly. There isn't always one obvious way to calculate how much space something actually occupies. APFS has its own quirks, some locations can't be accessed directly, and different types of data need different approaches. In practice, Trace has to combine filesystem information, metadata and heuristics rather than simply walking through every directory and adding up file sizes. A lot of the work since the first release has gone into improving that underlying analysis. Scanning large filesystems is considerably faster now, attribution has become more accurate, and Trace handles very large datasets much better than the early versions did. I've also added quite a few things along the way. Trace can now inspect and uninstall Homebrew packages, provides an overview of Launch Items, and several parts of the app have been reorganised to make the information easier to understand. The Info views are clearer, contextual right-click actions have been expanded, and I've spent a lot of time on smaller interactions so the app feels like a native macOS application rather than a third-party utility dropped onto the Mac. Trace is a native macOS storage analyzer and uninstaller. It scans the disk, breaks

I added a Meeting Mode to my Mac session manager, it hides your personal apps when you start screen sharing

Hi everyone, I'm Alex, the solo dev behind [Cove](https://covemac.app/). I posted here in June when I launched and quite a lot has shipped since, so here's a proper update. Quick reminder of what Cove does: it saves your complete Mac workspace as a named Session and brings it back in one click. Running apps and window positions, browser tabs in order, Terminal and Finder directories, VS Code / Xcode / Slack, and a Focus Mode that triggers on restore. A save/load system for your work setup. **Meeting Mode. (Image 1)** This came straight from my own habit of frantically closing windows two seconds before a call. When Cove detects you started sharing your screen, it offers to close your personal apps and tabs (Messages, WhatsApp, private tabs) so they're not sitting there for everyone to see. Nothing closes without your confirmation, you get the list and can uncheck anything. One click brings it all back when the meeting ends. It's the feature I use the most now. **Documents actually reopen.** Word, Excel and PowerPoint files come back with your session, including ones stored on SharePoint or OneDrive. Same for Pages, Keynote, Numbers, Preview and TextEdit. You get the real document instead of a blank window. **Finder got a lot better.** Windows reopen on the exact folder you had open, and folders now come back as tabs in a single window instead of scattered everywhere. Easily my most reported annoyance. **5 languages.** French, Spanish, German, Italian and Portuguese on top of

ExtraBar - An alternative to the typical menu bar managers like Bartender, Barbee or Thaw

Hey everybody! [ExtraBar](https://extrabar.app/?ref=reddit) lets you create a customized menu bar by injecting the apps you want into your menu bar with customized actions/menus. You can then choose how to display them (collapsed under a single icon, in the notch, in a floating bar or launcher style). What it is: \- A centralized hub to control your Apple Shortcuts, Script automations, keyboard macros, deep links. What is it NOT: \- A typical menu bar manager like Bartender, Barbee or Thaw. \- A way to hide/show your existing menu bar icons in case of notch overflow However, even though it is NOT it's main use, a side benefit of ExtraBar covers both - cleaner menu bar and thus notch overflow.
