alt Hacker NewsAsk HN: What Are You Working On? (July 2026)
What are you working on? Any new ideas that you're thinking about?

I built my own weather prediction / visualization app: https://wx.rsp.li (on-device temperature lapsing, on device interpolation modes, user-selectable aggregations, etc…). One of these days I should do a writeup.
I also asked Claude to build a photo gallery for me https://places.pascalspoerri.ch (HDR, map support, similar images)
I finally decided to put together a Sonos controller with the navigation I wanted and SMAPI servers for the live music archive, and all the grateful dead and phish shows. Thanks Claude! A PWA with tailscale and I have a controller that does what I want and works at home on an S1 system and at the beach on an S2 - seamlessly. Better than the "real" thing as far as I can tell.
A Web-based, self-hosted database client and editor for teams - https://github.com/p-raj/collab-sqlc
Supports - Postgres - DynamoDB - Clickhouse - Redis
Primary idea is to evolve from SQL client to a Database Client, where users would be able to host queries, share queries and the work remains auditable.
Previously it was an SQL client, a PopSQL alternative. But I am trying to re-work the architecture so that it can support more databases, and services (query-as-service, query-as-reporting-job, etc).
Just finished working on a new version of customizable Clarity Linux (GTK+) icons.
Created a new website and new icon manager: https://clarity.pl.eu.org
Complite - Elventy template/starter
And a Polish WikiZEIT project:
And ALT - LanguageTool for Emacs
I'm working on a nationwide US parcel dataset: https://www.kaggle.com/datasets/landrecordsus/us-parcel-laye....
It's mostly "public" data, but incumbent data vendors charge $90k+ for this data because it has to be acquired and aggregated from 3200+ US counties. This is a lot of work if you aren't using LLMs and agents to do much of the work for you.
I'm trying to make quality parcel data more accessible to everyone.
I am working on this Review Flow. An extention for Cursor / VScode to enable IDE as first class for code reviews.
It came from a frustration that I needed to switch between the browser and the IDE to navigate through the code and leaving comments on Gitlab at the company.
So I thought it could useful to create something and let it be accessible to the public as open source.
link: https://github.com/LuyandaLia/reviewflow
In a nutshell, it accepts draft comments, which can be modified and submitted.
It auto configs the env for Python as it uses FastAPI for calls to Gitlab.
It's my initial attempt. Suggestions, reviews, contributions are invited.
One love
Koji (https://github.com/iam-mhaseeb/koji) - A dead simple personal website engine for developers focused on simplicity.

I'm working on https://topicle.com/ An alternative to Reddit that more aggressively polices bots, spam and astroturfing and has strong guardrails in place against bad moderation. No private profiles that bots use to hide, every mod action can be appealed, mod logs are public, LLM posts are blocked. There's so much obviously inauthentic activity and questionable moderation on Reddit, I decided to try addressing it.
I’ve been exploring what sort of agentic tooling to write for creative coding and realtime VFX. My second iteration just got released earlier this week (also open source): https://sxp.studio/apps/subz
If you’re open to the idea of composing code blocks and ideas, plus some generative UI exploration, feel free to join!
Building a rootless, namespace powered (deeply stretching the definition of a container), on demand application workspace.
- Each component in a mini app in a heavily locked down container - Components are deployed and built in a web workspace, in the same workspace you can open a terminal and use your favourite coding agent to work on component code (each terminal is itself heavily sandboxes, has rw access only to the edited component code and users home dir) - Everything comes with heavy rbac and minimum permissions - Oh so much more
Explaining this well is hard, much like explaining to someone what Kubernetes or AWS does. This is at a level of what a sophisticated company infrastructure team would run, just as a workspace you can deploy for yourself easily and agents just build within that framework (I’m a cofounder of a infra/compute/datacenter startup and intimately familiar with this kind of complexity)
The main thesis is that Claw-style agents still feel like school projects, and that in the agentic era apps on demand will be more of a thing, and that the current systems weren’t built to deal with a whole new app built every few minutes.
May or may not end up as open source soon
I'm working on a collaborative post-apocalyptic fitness RPG. I wanted to build a game that lets you take over the real world, gets you off the couch, and has only positive multiplayer engagement. If you find or invite another player nearby, all your actions with them benefit you both.
It's for iPhone, and for the best experience, Apple Watch. It's very early, playable via TestFlight, and I would love feedback! There's a TestFlight link at: https://reverdure.yourstrategy.co
I’m trying to build the best TTRPG chronicler: https://loracle.app
Everyone who plays D&D has experienced the moment where they forget key details about the collective story they’re building. From ‘hey it’s been a month, where are we?’ to ‘wait who was this crazy npc again?’, ai is excellent at transcribing, notetaking and building a knowledge graph of your fantasy world.
I’m still building mostly for myself by adding a ton of features I know my friends would want, but also think there’s some ‘there’ there.
The idea is simple: let Loracle record your sessions on discord or upload the raw audio of your sessions, then get a rich personal wiki and session notes you can interact with.
If you’re mid-campaign you can also upload session notes from plain text and it bootstraps a campaign wiki. Then future audio based sessions have a good base of npcs, quests, characters, etc to build off of.
At this stage I’d love feedback more than anything else. Happy to comp a lot of usage to HNers in return for some reports on how well it’s serving you. Email [email protected] for anything and everything.
I've been working with coding agents for a few years and became increasingly frustrated by the way it pushes you towards a solution. So I built rubberduck (https://userubberduck.com/) - a way to control exactly what solution the agent ends up creating by mimicking a design conversation with a competent colleague where the agent explores the solution space together and forces you to make decisions. The final output is a consolidated design document of all the decisions you made. At least that was how it began. I've since built an implementation plan step where it figures out how to translate the design to code and execution where it actually builds it. All of this happens in a properly isolated environment (using gVisor under the hood). There are more features I want to build so on it goes I suppose.

Building a new Smalltalk VM from scratch that better utilizes modern hardware (full multicore support) and a web-based system browser so I can develop with it remotely.
I am building https://nexaflow.com - a customer support AI agent with built-in modules so small businesses need not buy 4-5 services to run a business. We ship with CRM, Ticketing, Appointment/Scheduler, Booking management system (for Small clinics, etc). Nexaflow agents can answer (and take action on) customer queries coming from Whatsapp, Email, Web (widget) and more.
Java Server Side Rendering Web Framework -- zero external runtime dependencies outside the web server layer -- https://github.com/vadimv/server-components The idea is to provide complete Java-centric modern web UI stack for building internal tools and admin panels.
https://cloudboss.co/docs/unobin
My original idea for this was to compile an Ansible-like playbook to a binary. I made a POC for it around 2020, and then it sat on the shelf. More recently I picked it up again following a more Terraform-like model. It compiles IaC to a binary with all dependencies included, standardized CLI options, autogenerated configs, optional visualization in the browser, and lots of other features.
To people who say just use Terraform: I do, a lot. But it still bothers me enough to try building something different.
I am playing around with creating a public domain repository for ebooks. https://babelnexus.com There are a few differences. It uses core collection theory and is selective. The name comes from the short story The Library of Babel by Jorge Luis Borges. Borges used Hexagonal Galleries for his library. I realized you could put anything into hexagonal galleries. It did not have to be books composed of random letters. I also saw that you could use different levels to group kinds of knowledge using the spiral staircase concept. I have added other concepts like reading trails and cortex maps. I learned that the hexagonal concept of Borges library matches with knowledge graphs with both nodes and edges. There is a lot of experimentation in what I am doing. It is an art project, a bit of philosophizing, a bit on the public domain and many other things.
I am building https://EasyAnalytica.com - single place for all your dashboards. It generates dashboards automatically from data without using ai. It supports getting data from google sheets, api's, url's etc. I have recently added support for gsc as data source and i plan to continue adding more in coming weeks.
Slowly improving the UX on my SQL review/approval tool: https://github.com/kviklet/kviklet
Also finally closed the first real customer on it recently!
I want to get through a large chunk of the open issues the next few weeks and then spend some time building agentic capabilities for it. I believe a central place to configure database access for your dev team without having to share passwords and with sensible review policies should also help e.g. if claude needs to access production data to validate a premise.
Still have to figure out the right UX though not sure the agent should have the exact same review requirements that a human does. Maybe it needs to be configurable separately
I’m working on https://main-duck.com/ which simplifies converting your code to mcp. I plan to make this easy to integrate into CI so mcps can be updated easily. It’s hosted remotely and I’m very excited about where it’ll go.

Always-free résumé (CV) website and PDF from plain text, grounded in the best resume-writing guide and the best designs.
Working on full stack prototyping agents that own their own Aws account (zero deploy friction). Think speed of lovable/ base44 with power of Aws services
I'm doing a personal research project into the technical maturity of ccTLDs. So far I've mostly been working with easily accessible public information, which I'm almost ready to publish, but the next phase is going to be trying to identify markers of stack complexity (provisioning etc) which is going to be tricky.
I'd love to hear from anyone else doing work in this area!
A text-based song format for generating music. I wanted to be able to create a song entirely using text, so I created a TOML-based format for doing so, and gave it most of the features you would find in a DAW. Since the format can be described in a SKILL file, AI can be used to write a song in this format, which can then be converted to audio.
I started burning down the backlog of all the stuff I wanted to get to for side projects but never had time for (before LLMs):
- https://smacke.net/ffsubsync -- automagically synchronize subtitles, now purely client-side in your browser thanks to pyodide
- https://ipyflow.github.io/ipyflow/lab/index.html?path=demo.i... -- reactive python jupyter notebooks, again in the browser thanks to pyodide / jupyterlite
- https://smacke.net/pipescript/lab/index.html?path=demo.ipynb -- magritter-like pipe / placeholder syntax for ipython / jupyter, again able to run purely in the browser
- https://smacke.net/pycograd/lab/index.html?path=pycograd_sim... -- pyccolo and pipescript-powered autograd, once again able to run purely in the browser since numpy has a wasm target (notice a theme here :) )
Working on https://razzify.in - Learn hacking using CTF challenges and get hired. https://securepilot.in - Indias first cybersecurity incident management platform for individuals.
I want fast answers to questions like:
"Why is Zoom lagging?"
"Is the issue my WiFi?"
"What's going on with the Internet?"
So, I built a local Mac utility that runs in the menubar to give at-a-glance visibility into live network and application issues. It's free (for typical uses), battery-efficient, and gives fast and reliable answers.
I’m working on Envelope. https://envelopebudgeting.com It’s a budgeting app that comes with a built in checking account and debit cards. Because your budget can actually decline card transactions it’s a very effective system for stopping overspending.
I’m currently migrating the codebase to Swift 6 and dealing with the new concurrency system.
Working on https://github.com/AqilbekAbilaev/ozendb
Free, open-source and drop-in replacement for Studio-3T. All the featured behind Studio-3T subscription for free in OzenDB.
Released beta version recently. Feel free to check out. Will be glad for feedback)
This month has mostly been personal website. Serious warning - style is an HN ripoff atm, forgive me in advance. Will change in the future to something original or minimal.
Migrated my beverages app from notion to an actual webapp my wife and I can use: https://stefanludlow.com/beverages/
Built a bunch of slime mold art: https://stefanludlow.com/art/foraging-network
Project I've got in progress is a migration of the old DIKU mud engine from C to Rust and making a Moog Model D synth recreation in rust with a JS wrapper.
I got sick of choosing between the efficiency of working in a terminal and the magic powers of using AI (and of copy-pasting between the two). So I created a hybrid: Terminai is a transparent wrapper for any terminal that provides on-demand access to a TUI coding agent of your choice just a hotkey away (with built-in MCP and CLI that gives the AI access to your terminal).
Still working on https://compears.shop we’ve added some new features to help people shop in the EU for cheap. I’m hoping we get to expand this to more EU countries
Note: this involves blockchain VMs. If that's a dealbreaker, feel free to skip. I get it.
I've spent 8 years working on RISC-V VMs for blockchains, recently also contributing to ZK VMs. Modern blockchain VMs are drastically more powerful, and I'm curious how far we can push them. I started porting real game logic to blockchain VMs, running game loop, physics simulation, collision detection, etc., on blockchain VMs. So far I have:
* Teeworlds to CKB-VM: https://xuejie.space/2026_06_16_teeworlds_on_ckb/
* One Hour One Life to CKB-VM: https://xuejie.space/2026_06_29_porting_one_hour_one_life_ga...
* A small ray tracer to Jolt ZK VM: https://xuejie.space/2026_07_10_cpp_ray_tracer_on_jolt_zk_vm...
Source is available for 2 of the 3, I need to clean up the OHOL one.
Some context: CKB-VM [1] is a RISC-V virtual machine I designed for Nervos starting in 2018. Jolt ZK VM [2] is a zero-knowledge virtual machine developed by a16z. Both execute RISC-V code, but due to different design, Jolt ZK VM is a much faster CPU than CKB-VM.
Technically this is a fun challenge. Many techniques I used resemble game development tricks from the 90s on game consoles: fixed point math, banked memory in ROMs, aggressively inlining tricks, etc. I want to push to see where the ceiling is. Right now I'm trying to get a Godot [3] + JoltPhysics [4] game loop running on Jolt ZK VM.
Happy to answer questions about the VM internals, the porting process, or anything in general.

I built a world cup tracker into an LED matrix display, and now I'm working on making it useful after the world cup
It's a calculator for what an AI feature costs to serve. Cost per request, cost per month, which part of the bill is eating you (output tokens, usually). No signup, all the math is on the page. Any feedback is welcome.
I'm working on the finishing touches for a big new "Event Filters" feature for my Shopify app, Stages (https://getstages.com). The feature will let users set up rules to decide which orders should be imported into the app based on certain criteria like Shopify product names, collection names, order value, and so on. Users have been asking for it forever, and I'm planning on publishing it this week!
I'm also working on an update to ShopifySharp, the .NET package I maintain for Shopify's graphql and rest APIs. I need to regenerate the graphql types and the fluent query builders for the July 2026 API version that was just released, and I'm planning on some extra QoL improvements that I've run into while using the package over the last couple of months. I particularly want to add some F# QoL features, since I wrote the package in C# but use F# in all my personal projects. (https://github.com/nozzlegear/shopifysharp)
Still a small plattform for groups of gamers to share their library with each other and suggest and vote on games for a game night. I'm planning on a group finder feature where you can publicly search for others to play with you, currently it's more angled at existing groups.
I'm working on MedAngle, the world's first Agentic AI Super App for medical and dental school. You can think of it as literally everything one would need from day one of admission till graduation day as a doctor.
I myself am the first medical doctor and full stack engineer in the history of my country (250 million), graduated as a doctor at age 25, and we have over 100+ users [all of which are medical/dental students and doctors], 10s of billions of seconds studying smarter, hundreds of millions of questions solved, and more.
Our Super App has subsystems including MedGPT, MedAgent, Spaci (our own take on spaced repetition) and much more.
We're bootstrapped, and continuing to scale. If you are in medical school or know someone who is, please reach out!

Working on Morpheus, an experiment to improve tool usage over small llm like Qwen 30b by introducing JEPA (https://github.com/ichiriac/morpheus)
A CSS/TS React component library inspired by BeOS. Been spending the last week cutting my teeth on font issues however
I'm not a big fan of the encroachment of AI into Adobe's apps, so I'm using AI to build a replacement for those apps (a small web-based photo organizer and editor, just the tiny subset of the Lightroom features I need for my workflow)
Rewriting the region drawing code in my LisaGUI project so it does per-word bitwise operations instead of per-pixel calculations. I'm using Claude to help plan and debug it, but I'm being careful to review all its outputs and make sure I fully understand what it's suggesting and why. I don't want to lose all my neurons to this thing...
I am working on 2 football game websites, one for world cup https://7-0worldcup.org/,and the other for Top 5 leagues https://38-0.one/ Developing game is easy now, but it is really hard for promotion.
I've got two projects:
We create a plan for your marriage proposal. I'm working with an event planner to create this!
This does review aggregation for businesses, and then a bunch of tools to help you gain insights, respond to reviews, and get more reviews. I just hired my first Sales/Marketing person to scale.
I will create coupon codes for anyone interested! Email is in my bio
Building South Africa's version of TCGPlayer/Cardmarket/etc, for Yu-Gi-Oh! https://lekkerduelist.co.za
There's competition in the other TCGs, and of course a 2-sided marketplace is one of the hardest things to seed. So this is mostly just a project that I can put any fresh ideas into that I wouldn't be able to at my dayjob.
