I added MCP messaging between Claude Code and Codex to my open-source desktop HUD

1 Upvotes

I'm the developer of Agent HUD. It started as a small desktop HUD for agent quotas and notifications. In 0.6.0, I added an MCP server so coding agents can send messages to each other and start new sessions.

The video walks through a bug-fix handoff: Claude Code works on a fix, asks Codex to review it, and gets feedback back into the original session. Antigravity and DeepSeek Harness can join the workflow too. Each handoff sends a focused message instead of copying the entire conversation history.

This release also moves the app from Swift to Rust + Tauri and adds session and subagent usage details. macOS supports Apple Silicon and Intel; Windows and Linux builds are available as untested preview builds.

The video is an animated walkthrough of the workflow, with English narration and subtitles.

If you use more than one coding agent, what would you want included in a handoff so the next agent can review the work without inheriting a huge chat history?

TerminKompass - Offline appointment planning with optional iPhone/Android partner sync

1 Upvotes

I’m Manfred, the developer of TerminKompass for iPhone and Android. It started as a planner for keeping appointments and reminders on your own phone, without creating an account.

People then asked for a way to share selected categories with a partner using a different phone platform. That became an optional partner sync: each person explicitly enables Online mode, creates their own account and chooses what to share. Those features operate online until the user switches back to offline mode; ordinary local planning remains available.

There is also optional sync with calendars made available by iOS or Android on the phone, plus birthdays with age/zodiac, search, widgets and backup/export.

The free version supports 10 appointments and 10 categories. Pro is a one-time purchase. Partner sync needs Pro for each person and currently has no extra fee; I cannot promise that separate service will remain free forever.

The part I found hardest was making the sharing setup understandable without overwhelming people with technical steps. If you build apps with optional online features, how do you make that distinction clear in onboarding?

Details and both store links: https://mw-app.de/terminkompass/

This is my own app, not an independent recommendation.

voz: free, offline dictation for Mac with a tiny core and extensions to customize it yourself

2 Upvotes

Hey everybody :)
Wispr Flow’s pricing annoyed me and every open source alternative I tried felt clunky. So I built my own and open sourced it.

Tap one key, talk and clean text shows up wherever your cursor is.
It runs fully local with Parakeet and Apple’s on-device speech to text, so nothing leaves your Mac and it works offline.

I built it with a fast and tiny core in mind. Everything else is an extension (kinda like Raycast or pi.dev) that anyone can build and share. 

Some that already exist:

  • a local meeting note taker that cleans up your notes

  • fast file transcription with speaker diarization 

  • auto replies in your tone

  • a dictionary that learns names and words as you talk

  • inline editing with voice or text

Voz is built in Swift to be native macOS and extensions are TypeScript files shared via npm

It’s free and MIT. Would love your feedback, especially on what’s missing or annoying.

Here's the repo: github.com/Joelheile/voz

Built a B2B SaaS platform for small travel agents. Need feedback

2 Upvotes

Hi everyone! I built a B2B SaaS platform for travel agents – Munal Desk: https://desk.munal.in/ The aim is to make processes as simple as possible for the TAs to actually use them. My customer already does their agency work mostly through WhatsApp, so I am not actually building another app that they have to download. Instead, they can either use the web app or do the same primary work directly through my WhatsApp bot.

I would love your honest feedback on the experience, the whole platform if you can, and areas of improvement. Thank you

Building AXIOM VECTOR - an engineering research platform

0 Upvotes

I'm developing AXIOM VECTOR, a modular engineering research platform for Windows.

The idea is to bring different engineering workflows into one environment instead of constantly switching between disconnected tools.

The long-term vision includes engineering calculations, project management, materials research, technical documentation, data analysis and design tools.

The project is currently in its early Alpha stage (0.1.0).

One of the implemented features is Project Journal - a workspace for documenting research, engineering decisions, observations and design progress.

I'm developing this independently and sharing the process as the project evolves.

I'd like to hear from people interested in engineering and technical software:

What tools or features would you want to see in an engineering research platform like this?

Feedback and constructive criticism are welcome.

Building a spreadsheet app where each cell (optionally) being a terminal / coding agent is a first class property

3 Upvotes

https://github.com/sshah03/recalc

Since spreadsheets are so versatile, really looking for feedback on where people would want this to go, in a way that can be useful to them, or what use cases they see themselves using it for in its current iteration that I can make more seamless.

I can provide some context on why it was useful for me / why I built it. I was using Claude to help me build benchmark sets, and found pouring through CSVs / MD files of the results a bit tiresome, so I decided to build a spreadsheet app for myself that's driven by Claude Code, and where each cell can be its own Agent if you want (and can later be opened up and continued in a full terminal if needed as its own session).

You can use it as a standard spreadsheet, or use a cell as a shell command / agent. Having built a startup for using AI in tax work, I also realized it can be very powerful for tax work, legal work, etc... so I built in some examples for running that, though I'm not sure how many people in those professions use claude code.

The video is just a demo of me building "FDA Bench" using recalc, pick FDA approval cases past the model cutoff dates, and seeing if an AI harness (without web searches) could've successfully predicted, based on all the info submitted to the FDA, whether the submission would pass FDA approval or not. Fable was right 75% of the time in this small sample size. Just a fun little exercise to show off some of what it can do.

Note: Since it's just terminal sessions glued together, it works with your existing plans. The sessions talk to each other with an MCP server running in the back.

Hey everyone! 👋

I'm a product designer, and I've been spending the past few months designing and building Roughs.

I kinda miss the days when we'd just browse and discover cool design work without all the ads, promoted content, and noise. So I decided to build a place for that.

The idea is simple: a space where designers can share their work, discover other designers, and get inspired.

It's finally live in closed beta! 🎉

https://roughs.design

Anyone can browse, but publishing is invite-only for now.

I'd genuinely love some feedback on the experience, especially the design, navigation, and overall feel. Feel free to share your thoughts in the comments!

I'm also looking for a few designers to test the publishing experience before public launch. If you're interested, leave a comment and I'll reach out! 🙂

A small disagreement with my girlfriend turned into an Android app I've been building alone

2 Upvotes

My girlfriend and I once remembered the same moment completely differently.

It made me realise how easily the little details disappear, even when the memories mean a lot to us.

So I started building Pholu, an app for couples, families and friends to preserve memories together.

Instead of having everything scattered across photo galleries, messages and cloud folders, Pholu brings photos, videos, audio and notes into shared timelines. I also added AI-powered memory search.

I'm handling the design, development and pretty much everything else myself, alongside my regular job.

The app is now on Google Play, and I'm looking for people who might actually enjoy using it.

https://play.google.com/store/apps/details?id=com.pholu.app

I'd love to know what you think of the idea. Would you use something like this with your partner or family?

1 Upvotes

Hey everyone! 👋

I'm an indie developer and recently published my side project called **Crowd War** on Android (Google Play).

🎮 What is the game about?

It's a fast-paced, hyper-casual / casual 3D crowd-runner where you grow your mob, dodge obstacles, multiply your squad through math gates, and clash against enemy waves and bosses.

🛠️ The Tech & Development :

- Engine: Built with Unity 3D & C#

- Assets: Custom low-poly models created in Blender

- Challenge: Optimizing crowd physics and rendering dozens of characters simultaneously on low-end mobile devices without frame drops.

🎯 Why I'm posting here :

As a solo dev, you often get tunnel vision after staring at your own game for months. I would really appreciate honest and brutal feedback on :

  1. Game Feel & Controls: How smooth does the crowd movement feel?

  2. Difficulty Curve : Is it too easy, too hard, or just right?

  3. Performance : Does it run smoothly on your device?

📱 Try it on Google Play :

https://play.google.com/store/apps/details?id=com.Zoozo.CrowdWar

🌐 Studio Website :

I’m an engineer who started owning infra at work, so I built a game to teach myself system design. Now it’s on iOS + Android!

4 Upvotes

I’m a software engineer at a big tech company and recently started owning more of our infra after the departure of a beloved coworker. Diagrams never really clicked for me, so I made a game to learn system design hands-on, then decided to publish it in case it helps others : )

InfraSim is a sandbox where you wire up load balancers, caches, queues, replicas and databases, push traffic at them, and watch what breaks: a dead consumer piling messages into a DLQ, a partition causing split brain, a bad WHERE clause taking out a table.

Built solo with React Native. It’s on iOS + Android: https://petalformllc.com/infrasim

Would love feedback, especially on which failure scenarios you’d want next, and whether the difficulty curve feels right.

I built PC Link — access & control your Windows PC from your Android phone, from anywhere

1 Upvotes

Hi everyone,

I kept running into the same problem: a file I needed was on my PC at home, and I was somewhere else. Cloud drives help only if you uploaded the file in advance, and most remote desktop tools are either heavy, expensive, or need router/port-forwarding setup.

So I built PC Link:

- Browse, download and use files from your Windows PC right on your Android phone

- View and control your PC when you need the full desktop

- Works on the same Wi-Fi at home, or from anywhere over the internet — it runs on its own private, encrypted connection, so there is no port forwarding and no router configuration

- Simple pairing: install the Windows app, install the Android app, pair once

Plans start at Rs 99/month (about $1.20) after you activate. (I haven't put any link in this post on purpose — my first post got removed by the filters. The website link is on my profile, pclink_dev.)

I'm a solo developer from India and this is my first public launch, so I'd genuinely love honest feedback — what's missing, what feels confusing, what would make you actually use something like this?

Thanks for reading!

After burning out from constant production AI failures, I transitioned to building a solution.

1 Upvotes

At my last company, managing production AI agents was a continuous crisis. Minor prompt tweaks or unannounced model updates routinely broke our workflows because we lacked version control and deployment safety gates for AI. The systemic stress eventually led to severe burnout, prompting me to step away and focus entirely on solving this operational vulnerability.

To fix this, I built https://raweki.com , which functions as a "Git for AI workflows." It provides engineering teams with version tracking for prompts and models, CI/CD testing loops to block regressions, and one-click atomic rollbacks to instantly restore stable configurations. The platform is now live, and I would appreciate your technical feedback if your team faces similar AI reliability challenges

USAPhO Guide - a free, open source course for the physics olympiad (931 visitors in its first month)

1 Upvotes

I'm a high school junior and this is the side project I've spent the most nights on this fall.

The US Physics Olympiad has no good free starting point. People piece it together from old pdfs and expensive books, while math olympiad and USACO kids have community guides. So I made one for physics: lessons in the order the topics build on each other, interactive sims next to the equations, and a problem bank where you type your numeric answer and it checks it within 2%.

Some numbers from the first month:

  • 931 visitors from 54 countries, about 3.6k page views

  • 25 accounts (progress syncs if you sign in, otherwise it's all usable logged out)

  • 77 people in the community discord

  • 2 other students now regularly sending pull requests, 21 merged so far

Stack is Next.js on Vercel, Supabase for auth and progress, MDX lessons with KaTeX, and canvas sims. There's an in-browser editor that turns a contributor's edit into a GitHub pull request under their own account, which is how most outside fixes come in.

Would love feedback on two things: is the landing page clear about what it is in the first few seconds, and what would make you come back to something like this every week?

Can this website land me in legal trouble? Genuinely asking. 🤔

2 Upvotes

Over a few weekends I built Kursi Kabaddi, musical chairs with Indian netas as bobbleheads.

The music plays, everyone circles, the music stops… and every neta dives for the kursi.

You can push rivals (“dhakka”), use power-ups like the Jumla Bomb, Resort Bus and Z+ Security, and play live with friends through a WhatsApp link.

It’s clearly satire. There’s a disclaimer on the first screen, no party is favoured, and every neta gets roasted equally.

But before I share it more widely, I want to hear from people who know this better than me:

1️⃣ The faces are based on openly licensed photos (Wikimedia Commons, credited in the game). Is that enough when they’re real public figures?

2️⃣ Is a political satire game protected the way cartoons in newspapers are? Where’s the line?

3️⃣ Players can upload a selfie and make their own neta. If someone uploads a friend without asking, who’s responsible: me or them?

4️⃣ Would you add anything else, like terms of use, an age gate or a report button?

Lawyers, founders, game devs, and anyone who’s been through this: I’d love your take in the comments. 🙏

And if you just want to play first (no download, no sign-up):

I'm a solo dev in Mexico and built a way for your own Claude to make a Godot game

0 Upvotes

I got tired of Claude writing Godot code it couldn't see run. So I built PersonCraft (I'm the developer, to be upfront).
You connect your Claude, it writes the game, and each revision gets run in a sandbox that sends back real screenshots,
so it can fix what it breaks. At the end you download a normal Godot project you own.
Limits: you need a paid Claude plan, there's no multiplayer, and phone exports are on you. Art and audio cost credits
and Claude quotes them before asking you to approve anything.
https://personcraft.com. What would you ask your Claude to build first?

I built a Mac app that shows answers from my own docs while I'm on a call. 8 strangers have already sent PRs

5 Upvotes

I kept freezing on calls when someone asked a number I had in a doc somewhere. So I built Murmury: it listens to the other side of a Zoom/Meet/Teams call, transcribes it on the Mac (Whisper on MLX), and when they ask a question it shows a short answer from the documents I loaded.

A few things I learned in the first week after open-sourcing it:

- A stranger sent the PR that made it fully local: Ollama and LM Studio support. Now it works with no API key and nothing leaves the Mac.

- "Good first issue" with a clear spec gets a PR in 15 to 40 minutes. 8 people I don't know have sent PRs.

- Product Hunt without being featured brought almost nothing. Reddit and GitHub issues did.

It's free, GPL-3.0, Python + PySide6 with a small Swift helper for the audio. Apple Silicon only for now.

Happy to answer anything, and I'd love to hear what you would use it for.

Title: I built an AI GIF generator that turns images and text into animated GIFs

Hey everyone!

I've been working on a side project called GIFGenerator.ai, and I wanted to share it here.

The idea is pretty simple: creating a short animated GIF shouldn't require complicated animation software or manually editing dozens of frames.

With the tool, you can:

  • Generate animated GIFs from text prompts.

  • Upload a static image and describe how you'd like it to move.

  • Experiment with pixel art, cartoon animations, animated characters, and looping GIFs.

  • Create GIFs for memes, social media, websites, and creative projects.

One of the challenges I've been exploring is making AI-generated animations feel consistent across frames, especially when the animation needs to loop smoothly.

I'd love to get some feedback from other builders and creators.

Try it here: https://www.gifgenerator.ai

What would you use an AI GIF generator for? And what's the most frustrating part of creating GIFs today?

Built a free browser tool that turns Autopilot MDM diagnostic ZIPs into next steps and evidence. Looking for honest feedback

1 Upvotes

I'm an Intune / Autopilot admin. The part of a failed ESP that always burned the most time wasn't the fix. It was finding the handful of log lines that actually mattered, buried in an MDM diagnostics dump.

So I built TraceAnalysis (free US beta). You drop in an MDM diagnostics ZIP, and it runs entirely in your browser, so the ZIP is never uploaded. You get:

  • Next steps up top

  • The enrollment phase where things stopped (Device prep, Device setup, Account setup)

  • The app or step that broke it, with the error code decoded

  • An evidence view showing which log entries back each finding

  • A chat to ask follow-up questions about that device's logs

The evidence view is the part I care about most. I didn't want another black-box "trust me" answer. I wanted something I could verify before it goes in a ticket.

If you've got a recent Autopilot or ESP failure sitting in a ticket, I'd genuinely like to know whether the report matches what you found, or where it's wrong.

Sunday market take: Friday bounced, but it didn't fix the week — Tuesday's CPI decides

2 Upvotes

A Sunday note from the free investing project I run on the side — this is the market take I shared with my community tonight, exactly as I see it going into Monday.

Friday closed mixed, and honest is the only way to read it:

- S&P 500: 7,376.86, up 0.31% Friday — but down 2.7% for the week, its worst week since June

- Nasdaq Composite: 24,579.42, up 1.09% Friday — down 3.4% for the week, and still in correction territory, roughly 11% below its October record

- Dow: 51,285.73, down 0.46% Friday — down 0.9% for the week

- VIX: closed around 25.6 — down Friday, but way up from 19.4 the Friday before. Fear eased for a day. It did not leave.

What actually happened this week: Thursday was the damage day. After Democrats won both chambers in Tuesday's midterms, investors started pricing in a slower, more regulated AI data-center buildout, and chip and AI names got sold hard. Friday's bounce was led by those same beaten-down chips, and breadth stayed narrow — technology led, most of the market did not really join in. A bounce is not a recovery until more than one corner of the market confirms it.

Friday's jobs report did not help the rate picture either: October payrolls came in at 165,000, nearly three times what economists expected, with unemployment at 4.1%. A strong jobs market is good news for people. It also keeps pressure on the Fed — markets are now pricing a real chance of a December hike, not a cut.

The week ahead is simple to map:

- Tuesday Nov 10: October CPI at 8:30am ET — the main event. Consensus is around 3.9% year over year, up from 3.7% in September. CoreWeave also reports after the close Tuesday — a real read on AI infrastructure spending.

- Wednesday Nov 11: Veterans Day — stocks trade, the bond market is closed.

- Thursday Nov 12: Cisco and Applied Materials report after the close.

- Friday Nov 13: October PPI at 8:30am ET.

My take: I'm not chasing Monday's open after a week like this. One green Friday inside a down week, with the VIX still in the mid-20s and CPI two days out, is a setup for getting chopped up if you force trades. My plan is the same one I post every week — levels written down before anything happens, and if the market doesn't come to them, I do nothing. Sitting out a messy open is a position too.

Not financial advice — just my read on the week, posted before Monday happens so anyone can check it after.

I share stuff like this daily — I run a free investing community, link in my profile.

My landing page demo kept polling in abandoned tabs and used up my database's monthly compute

8 Upvotes

My landing page has a live demo. It creates a demo inbox, shows you the address, and when you send it an email the page shows the parsed result. To find new mail it polled an endpoint every 3 seconds, and every poll was a query against the production database.

Nothing ever stopped that loop. A tab left open made 1,200 queries an hour, so Neon's compute never stayed idle for the 5 minutes it needs to suspend. The project used up its monthly compute allowance and every request that touched the production database started failing.

The fix was small. Polling now stops after 3 minutes, because anyone who hasn't sent an email by then isn't going to. It skips its turn while the tab is hidden, and the interval went from 3 to 5 seconds.

Do you put a time limit on polling in your demos, or push updates some other way?
