alt Hacker NewsAsk HN: What are you working on? (January 2026)
What are you working on? Any new ideas that you're thinking about?
Comments
I am working on a camera module that has SLAM built-in: https://x.com/_asadmemon/status/1989417143398797424
Running on a single-core armv7. It includes a VIO and a nice loop closure. I am now optimizing it further to see if I can fit some basic mapping too.
Still working on PocketWise (https://pocketwise.app), a simple double-entry accounting app. Just finished adding end-to-end encryption with a zero-trust server model. All encryption and decryption happens in the browser (using PRF), and the server only sees encrypted data.
I finally decided to promote my gitignore pattern Python library, pathspec, from v0.x to v1 after 12 years or so.
I'm thinking of reviving my Python SQL parser prototype I have half done. Or maybe resume my Mako template plugin for PyCharm.
TCKR - Scrolling Stock LED Ticker for Windows https://github.com/krypdoh/TCKR
I've been working on this for several weeks/months and I'm happy with the result!
Vibe coded it as my programming skills have eroded with time (or they never existed).
I would really appreciate some feedback.
I'm building FollowGuard (https://followguard.app) - it's a privacy-first Instagram analytics tool.
I got tired of seeing people lose their accounts to "unfollower" apps that require login credentials and use unofficial APIs. Instead, I built this to parse official Instagram GDPR data exports 100% client-side in the browser.
It’s a Vue 3 + TypeScript SPA. There is no backend; all the ZIP extraction and JSON parsing happen locally so the user’s data never leaves their machine. I even added a "Security Audit" feature to help people find suspicious login activity in their own data.
My biggest challenge right now is the UX friction. To stay safe, the user has to navigate an 11-step manual export process on Instagram to get their data. I’m trying to figure out if the "privacy/safety" benefit is enough to convince non-technical users to jump through those hoops.
Building Cassette: a dead-simple computer in the cloud: https://cassette.sh
One always-on Linux box to run apps, databases, CI, and AI agents without hyperscale complexity, surprise bills, or Kubernetes. AI-driven app explosion plus mature open-source deploy tools make simple servers fast, cheap, and fun again.
I'm working on Narwhal, a pub/sub protocol and server specifically designed for edge applications. The protocol can be extended via an external component, and the product is completely free and open source: https://github.com/narwhal-io/narwhal
The easiest and simplest calorie counter
Writing a WebAssembly module parser from scratch, focusing on good diagnostics/errors and DX.
Currently it's fully-conformant to v2.0 of the spec, while I'm working towards implementing the recently released 3.0 version.
"Hold for Me": uses LLM to detect when somebody picks up your call https://github.com/predkambrij/Hold-for-Me-using-ADB
Continuing to build GhanaHousePlanner https://ghanahouseplanner.com/, currently focused on enhancing the cost accuracy and constraint solver for the generated house floorplans.
I am super curious about tensor parallelism and the mechanisms behind how some models can activate only some of their attentions.
I’m a remote dev building an iOS app called Springus. You add a few pics / your closet basics, and it suggests outfits based on what you already own. It’s less “fashion app” and more “tiny morning momentum hack.”
Would love feedback from other WFH folks — a weird amount of my productivity comes down to how I start the day.
I'm building https://swishfinance.app - minimalistic and simple stock widgets for your PC. That way I no longer have to make a conscious effort to check my portfolio — it's just there on my desktop.
Platform for apps, currently Lua support ( future WASM). Think like apk (android app) but spk.zip that has server.lua file for backend and htmt/js/css that get served for front end plus platform gives Files, SQLite db (namespaced/scopped access ), Auth, User management All in single static binary Cz go
Edit: formatting
I have been working on the next generation of Canva and Photoshop for highly regulated verticals where there are specific demands placed on the generation and edit flow.

I'm still working on my Web Server Library .NET Core
I'm rewriting from scratch : https://simplew.net/v26/
I am working on SIP4AI [1] (a VOIP soft-phone where AI is on the other end, not a human). You can self-host it, register a SIP line, and let AI take the calls.
It works with your existing phone system, so you can just add AI as a line without having to replace everything…
meta-analysis, make Claude write a blog post, connecting and deriving set of concepts across a range of books, articles, papers, etc. Basically a syntopic reading machine. Its a meaty side project (and expensive), but I am curious how close I can push this. My current approach relies on a tool that I have built recently [0], it's an agentic memory but I am using a new memory model that is based on Zettelkasten principles.
What is really cool about it is that it natively capture connections between atomic ideas and evolve them. Which I believe it gets me one step closer to syntopic reading machine.
I’m working on agent-os: a slf-hosted web UI for managing multiple AI coding CLI sessions (Claude Code, Codex, OpenCode) with multi-pane terminals. All free and open source: https://github.com/saadnvd1/agent-os
I am working on an failure proof introduction to Lisp/Scheme for imperative programmers. I always thought there was something unapproachable about Lisp. But I finally figured it out, and I want to document my path for people like me. It's going to be great. Expect to be done in a week or so!
A personal agentic tool for action cam video editing. When I moto / ski / bike, I leave my helmet cam rolling the entire time. It takes a very long time to 1. find scenes and 2. edit them down into a reel or video. It works well for my amateur use case - basic edits with only cuts and transitions.
Building a 22-service e-commerce platform in Rust (Runs on ~300MB RAM)
I'm 17. For the past 6 months, I've been diving deep into Rust to answer a question for myself: "Is Rust actually viable for complex, enterprise-grade backend architectures, or is it just hype?"
To test this, I built a full distributed e-commerce system (22 microservices, gRPC, Event-Driven) using Axum and Tokio. This is not meant as “how everyone should build”, but as an exploration of trade-offs.
Some hard lessons I learned along the way: Complexity vs. Performance: … The "Memory Shock": … (idle baseline; load benchmarks still in progress) Over-engineering: …
I'm currently squashing the final bugs…
I'd love to hear from senior folks here: …
Solving L2 DAO retention incentives
https://sendbroadcast.net - I've been working on it since October 2024, and it's still going strong.
Currently on v1, but working on v2 release in the next month.
I've been experimenting (over 130 test batches so far) with creating an all-purpose balm (lip, hands... stuff).
I wanted something more useful to carry than typical gooey lips balm full of petroleum and silicone.
A domain-agnostic, open source scientific database.
“Protein Data Bank-in-a-box”
I'm having fun playing around with AI by building a coding agent with both a CLI mode and a web UI https://github.com/martydill/flexorama.
Building something is a nice break from the corporate world.
A domain-agnostic, open source scientific database.
“Protein Data Bank-in-a-Box”
I'm still working on my PDF search engine for desktop: https://www.docgoblin.com/ I'm implementing a bookmark utility right now and hope to add support multiple E-books format in the near future.
Working on a job board as a service. [1] I'm hoping that communities, bloggers, or newsletters pick it up to monetize their audience.

I've been experimenting with what a serverless cloud platform would look like that networks wasm components using gRPC:
I'm building a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. Back in December Gaming Couch hit the front page of Hacker News, you can check it out here: https://news.ycombinator.com/item?id=46344573
The TL;DR:
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs are necessary to play
- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!
- In the future the plan is to open up the platform for 3rd party developers (and Gamejams!) as well. We'd take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking code and building the infrastructure.

Working on https://greatreads.dev/ A place to aggregate and find articles from developers' blogs.
Always on the look for new sources to be added. If you have a blog or read any that you want to recommend. Just let me know.
ALT (https://www.APILoadTest.com): I recently built ALT as a no-code platform to load/stress/performance test APIs with pre-defined (and customizable) load profiles, via globally distributed machines. The goal is simple: key performance metrics, in seconds, without scripting. I also added the feature to directly import collections from Postman.
Here's a walkthrough of how ALT works: https://youtu.be/m2MER0KW3yA
A little static site generator using ruby templating engines:
I'm working on an app to make testing available to all brick and mortar retailers (proofpod.ai).
The most difficult technical challenge has been designing a pipeline to fully automate choosing test & control locations using synthetic difference-in-differences.
I wanted to learn a new(ish) skill and am building a button box for sim racing with Arduino Nano, momentary switches, etc. It has been about twenty years since I’ve touched a soldering iron or built any kind of breadboard circuit.
