alt Hacker NewsAsk HN: What Are You Working On? (April 2026)
What are you working on? Any new ideas that you're thinking about?
Comments
just a weekend project. a bulletin board to share ideas with the internet haha - https://www.litboard.net/
It's not software related but could be in future.
My father, a documentary photographer and political dissident during communist regime in Czechoslovakia have a large photo archive that he was never able to publish. I have launched a public fundraiser to support the digitization and publication of the photo archive. There are many valuable photographs that public should see.
More info about project: https://tobiaskucera.art/en/digitalizace-fotoarchivu-meho-ot...
I'd like to create a web catalogue that anyone could search photographs by date, place, names, etc. I'm not sure what backend should I use. Immich has nice features like face detection, search by content, GPS, etc. but it is not suitable for front end.
I'm working on building Orris (https://apps.apple.com/us/app/orris-breathing-exercises/id67...): a breathing app for iOS. Built it because I wanted something simple for winding down before sleep and everything I tried was either bloated with content I didn't want or locked basic features behind a paywall.
It does guided breathing sessions with variable phase durations (4-7-8, box breathing, etc), streak tracking, and HealthKit integration. It's all based on SwiftUI, Swift 6, with no backend. Currently exploring adding ambient soundscapes for sleep sessions.
Solo project, been working on it for a few months on the side. Also been a fun journey back into iOS after almost 10 years away!
I vibe-coded a tiny local code review tool, a bit like pull-requests, but an agent does the work immediately.
https://github.com/antoineMoPa/moonreview
The intended use is to run `moonreview` instead of `git status` / `git diff` or `magit`, but you can add comments and they get auto resolved. You can also stage hunks if you are happy with them.
Probably other tools exist or will appear in this space (I saw at least another one in the comments on this post), but i think there is something fundamentally too slow and dumb with current corporate code reviews. People are reviewing other people's slop and most of the comments are probably fed back into an agent. So why not have the whole process be done upfront by the original developper. Another cool thing I saw people do is to attach claude to github PR comments, which I think is great and love to work with this, but it's even better if we can also have this locally to catch sloppy code before it even reaches github.

A couple of things: 1. data management for music publishers. This came out of nowhere but has got me back into coding, deploying, test. And I've got real lessons using AI-generated code that I wouldn't have got just reading other ppl's blog posts! We've been mapping all the data formats publishers work with, how to organise them better and build a suite of apps around it.
2. the other projects it the framework. Aside from the product itself, I've ended up with a really nice framework (FE and BE) and playbook for copilot to follow. I've hit multiple problems with AI generated code and had to rework it like I have for junior devs! But now, the framework focuses the work and stops the slop!
I want to build out all the product-dev-helper tools I've wanted in the past. I've already got a lovely schema-UI system, UI components which are data-aware and the basis of some low-ish-code tools. I've also nearly got a "run tests and fix" local LLM which saves tokens.
Really enjoying this.
I built ReceiptBin because I wanted a simple way to track receipts and link them to my budgeting app. There are plenty of apps that already do this, but most of them feel out of place on iOS and lock basic features like OCR and autofill behind paywalls. ReceiptBin uses Apple’s VisionKit and Foundation Models to handle OCR and autofill at no cost. Everything syncs through iCloud, and you can generate reports entirely on-device. There’s also support for widgets and Siri Shortcuts.
If you want to check it out: https://apps.apple.com/ca/app/receiptbin/id6761148891
I’m planning to push another update in the next few weeks with bug fixes and some new functionality.
From another submission (https://news.ycombinator.com/item?id=47738827), there was a screenshot of Google Docs/Drive showing a popup saying "You cannot do copy/cut/paste with the mouse" whenever you try to right-click and copy.
Some months ago, I saw that very popup, and finally started working on something I've been wanted to do for a long-time, a spreadsheet application. It's cross-platform (looks and work identical across Windows, macOS and Linux), lightweight, and does what a spreadsheet application should be able to do, in the way you expect it, forever. As an extra benefit, I can finally open some spreadsheets that grown out of control (+100MB and growing) without having to go and make a cup of coffee while the spreadsheet loads.
I don't really have any concrete to share, I guess it'll be a Show HN eventually, but I thought it was funny it was brought up in a similar way in that article as was the motivation for me to build yet another spreadsheet application.
I'm making web chat using captive wifi portal on esp32.
stk (https://github.com/level09/stk): async Quart + Vue 3 starter i use for everything. auth stack is already wired up (session, 2FA, webauthn, oauth), async sqlalchemy, alembic, no frontend build step. basically the boring part so i can get to the actual product faster.
ziglag (https://github.com/level09/ziglag): self-hosted invoicing for freelancers, built on top of stk. clients, invoices, VAT, PDF, shareable links, MIT. got tired of paying a monthly fee to send a pdf.
idea is to keep chipping away. every subscription that annoys me is fair game. small tools, self-hosted, no accounts, no seats, no upsell. if it's useful for me someone else probably wants it too, so might as well open source it. open to ideas on what to kill next.

I'm getting pretty darn close to doing a "Show HN" about my new macOS paint app, called Mojave Paint. I just posted a feature tour video at https://www.youtube.com/watch?v=61FJ2xzUiIU showing how to make halftoned edges, which happens to cover a lot of of the basics including layers, alpha masks, selections, foreground/background color, gradients, etc.
I would say Photoshop is awesome but expensive (if you can look past how invasive it is for your machine), Affinity is free but "meh", I'm going for the "awesome and cheap" square of the quadrant. Find it at https://skullrocksoftware.com

Working on a lot of projects, both at work and personal, but if I'm honest I want to create something now. Pottery, woodworking, agriculture, whatever. I'm tired of writing code, really. It's boring to do, it's boring to tell others what you do, and frankly I am contributing little to none to society other than saving money for others.

Wow this is an unreal way to get some karma hahah
I've just published Timelocked (https://github.com/Caltanjun/timelocked), a local app that encrypts any file or message but delays decryption.
One of the main goal is to help with cryptocurrency-related home invasions. The XKCD "$5 wrench attacks" became a reality in France where I live. So it's another way to delay the access of personal funds, but it doesn't need to rely on third parties or multisig. You can just timelock a BIP39 passphrase for a duration of your choice.
It can also help with self-managed inheritance, or digital addictions.
a soft-state filesystem cache and cluster control system that doesn't require any external orchestration or micro service infrastructure
i'm creating (another) learning platform so people with no background in tech can learn sql and python for data analysis
I am building https://ranktools.io An SEO lead generation SaaS that builds interactive content on user’s websites.
Ranktools builds content like tools, calculators, generators - publishes them, builds backlinks on autopilot and generates leads via CTAs built directly into the tools.
It’s also not AI slop as a human reviews every piece of content before it goes live!
I've been busy adding postgres and sqlite support to apostrophecms:
Six months ago, that would have been unrealistic, because we're heavily committed to the mongodb API and we make it part of our own API.
Starting in December though, Opus 4.6 made it perfectly realistic to pursue this with Claude Code as a series of personal weekend projects.
Now, despite not having any official resources on this until the last week or so, it should land in May.
This doesn't work for everything. It absolutely helps that the problem I'm solving is an "adapter pattern" problem: "make X talk like Y." And that we have a massive test suite, at multiple levels. That combination makes "here's the problem, go solve it, grind until the tests pass, don't bother me for a few hours" a realistic AI agent request.
But it's a little mind-blowing all the same. The hype around AI is so out of control, it can be easy to miss genuine "holy crap" moments.
Along the way I've written a fair bit about how to run Claude Code autonomously on your household server in a reasonably secure manner:
https://apostrophecms.com/blog/how-to-be-more-productive-wit...)
Also general Claude Code tips and thoughts on workflows that help and workflows that ultimately just speed your burnout:
https://apostrophecms.com/blog/claude-code-part-2-making-the...
I know, everybody's writing this stuff, but the desire to share is natural.
(Disclaimer: I'm part of the demographic AI was trained on. If I tried not to sound like a bot, I'd have to sound like... well, somebody else)
I got tired of paying lots of $$$ to form tools, in order to create useful forms and checklists for me, and with my specific requirements:
- immutability
- self-hostability and/or EU SaaS option
- nested data (e.g. nesting a list of sailing legs into a sailing trip form)
- formulas (today(), date, string, numeric,...) and conditionals (visible/required/enabled if)
So I created two nice pieces out of that, which would have been impossible in the past due to time constraints and got massively unlocked through claude code:
- a frontend/javascript only forms library that supports all the rendering, form schema input, data output, validation and formula/conditional logic
- a multi-tenant SaaS product, that is a single golang binary and stores in sqlite, easily self-hostable but I can also operate it as a European SaaS (and in other regions) where needed
So I was trying:
- pocketbase
- really running something bigger with much more data off of sqlite (primarily used it for smaller stuff in the past)
- real focus on self-host-ability, keeping dependencies minimal and extremely simple (which also helps claude)
- trying other tools for security scanning, verification, testing, security analysis, WAF,... than I use at work, pretty much playing around with tech as much as I can to see new and different stuff :-)
I am working on a (yet another) local app for managing multiple claude/codex/gemini sessions in a game like environment: https://getviberia.com/
https://auxx.ai Yet another "AI CRM" Started over a year ago working on it part time. Its coming together. https://auxx.ai
Recently started a web design and IT consulting company called Opacity Tech with a simple goal, reasonable prices, and handwritten code. No AI agents writing bloated code, no template based site builders. Just real humans, writing real, optimized, fast code, using experience and knowledge, like the old days. Art used to be what we created with our hands, not what robots hallucinate for us. This from scratch attitude means we can charge less because we dont have to rent platforms or pay subscriptions for services or licenses. Real servers in house too, no cloud overlords.
Hello I'm making a game.
I built a cmux-like sidebar for a fork of wezterm, called wezmux https://github.com/vcabeli/wezmux
If you know, you know. I wanted to like cmux but I had tons of problem with fonts or scrolling behaviors and I don't need a web browser in my terminal, so I went back to wezterm and added the nice sidebar for my claude code / codex notifications and output previews.

turns out starting a popular open source project comes with ongoing work attached
Been building an E2EE chat client on the weekends that sits right between Discord (but dis-enshittified) and Matrix (but with good UX around encryption). Still got some rough edges - we are in the second nine of the march of nines in terms of quality.
HTTPState
https://github.com/httpstate/httpstate
A minimal, reactive, real-time state layer over HTTP. Pick a UUID, read/write ≤128 bytes, and instantly sync data across apps, devices, or services. Each state is addressed by a UUID [1]. You read/write it via a simple GET/POST API, or use one of the client libraries (8 languages and counting) for real-time updates. It is open source with a permissive license.
Some design premises:
* It should be as easy as possible to use. One line of code (ok, two if you count the import line).
* Hard limit: max. 128 bytes state size. This forces small, fast updates. HTTPState is not meant to be a storage layer but a fast, real-time communication layer for things like events, sensors, UI/UX updates.
* Data is open, to re-usability and collective applications. You can see some featured data streams on the site, if you like one, you can use it on your app in like 1 minute.
Use cases (but not limited to, lol):
* Add pub/sub-style communication to your apps, quickly and easily.
* Stream sensor data to a web/mobile UI (or any of the client's implementations).
* Persist state across multiple runs of your app through time.
* Sync state across multiple app instances.
Some undocumented integrations (will land soon):
* You can update a state via an SMS message.
* You can update a state via an email.
* You can update a state by setting an HTML form's action to httpstate.com/UUID, so that it works on "noscript" environments.
* CAS-style optimistic concurrency control (w/ atomic operations) via headers on the request.
* There is an iOS client that allows you to easily build widgets with the states you choose.
Roadmap:
* Add "API Keys" so you're the only one who can read/write to the UUID you pick.
* C/C++ and MicroPython clients for embedded devices.
* A postgreSQL extension to bind states to tables.
How can you help?
* Just reach out if you want to adopt one of the clients and/or want to write a new one in a language/platform you'd like to see.
* If you know how to code Android apps, I'd like to have the same widgets feature I have on iOS but on Android.
* Publish some data and send me an email so I can add it to the featured list! (This will be automated eventually, I just haven't figured out in such way that is not abused).
* Comments and suggestions always welcome!
1: You can write it without the dashes, but it has to be a UUID v4. You can also add '/[8 hex digits]' at the end, this is helpful to keep many related states together.
I'm building an immediate mode GUI Win32 app on top of Windows.UI.Composition visuals, maybe building up a library with it along the way. Just a hobby project / experiment. I hate this problem [0] so I went down a rabbit hole trying to solve it.

Direction - I’m trying to teach people how to do all the other stuff that you need to know, other than writing code, about delivering real products and not just a bunch of junk and slop that can’t be maintained
ShowHN: https://news.ycombinator.com/item?id=47721469
I’m also trying to make it really super simple so it’s week to week pricing, and have a discord community that grows out of it.
It’s literally just four two hour courses on Monday of each week and a demo day.
you walk through what you’re gonna do, how you’re gonna do it, how you’re gonna use your AI assistants to help you, where it can help you, and where it can’t help you, how to talk to it about teaching you instead of just doing it for you, and at the end of it you have something tangible to show for it.
There’s no subscription this is just straight up teaching product and project development that comes with a community and the community grows as much as it chooses to.
You can read the vision and roadmap on the site as well
Finally starting a blog.
Building a pro transparency writing tool that cryptographically proves a human actually typed what they claim to have written (research papers, news articles, assignments etc) . It captures behavioral signals during composition, makes it very hard to automate or fake the writing process, and lets readers verify authorship authenticity. Think "proof of human work" for the AI generated slop era.
i am building yet another ai powered language-learning app. user uploads random texts, and the ai gives grammar and vocab hints, so the user can try to translate it on their own. Basically google lens, but without the final translation.
ironically the difficult part wasnt the OCR or the textanalyses, but finding the exact position of the text in the input image.
I'm working on the wolrd model action (WMA) model, which is used to replace Visual Language Action (VLA) model to bridge the physical world with LLM.
Now I've done my basic researching part, but I'm lack of the courage to dive into this topic. After all, it's a really hard work to it.
So I'm just, you know, scrolling the HN and trying to sharpen my brain and get back to the work.

I've coerced Codex and Claude to build Cloudflare-but-shit because I wanted to have healthcheck-based DNS records (A, CNAME) so I can host stuff on 100 RPis in 100 different places with any type of connection (public IP or behind a CGNAT).
It has DDNS, Tunnels, very-flexible-record definition and Anubis will be implemented soon or you can bring your own.
Powered by PowerDNS and Rails, and if I get some free time I'd like to just have this as an actual offering since I always fear Cloudflare putting more and more things behind a paywall.
Shockingly, it works, obviously the DNS I'm doing now isn't RFC compliant, but this already scratches my itch.
