Streamish
A music server compatible with multiple third-party mobile apps, particularly Synology and QNAP apps, currently in personal use ahead of launch, with planned Plex support next.
Fantasy desktop personal website
This personal website features a fantasy desktop theme, a redesign the author had wanted to make for a while.
React in Godot
A complete implementation of React for the Godot game engine, enabling UI such as HUDs and editor interfaces to be built with React instead of Godot's control nodes, which are cumbersome to work with. Planned for open source release; the migration of Breaka Club's HUDs and editor UI to it is planned. Still being optimized.
SDK Garden
This tool provides SDK observability, sitting at the intersection of observability, SDKs, and product analytics. It ingests data from monitoring services like Datadog and Sentry to give visibility into SDK usage, filling a gap where no existing SDK observability tooling could be found.
SimRacer
This is a mobile car racing game featuring novel one-handed controls.
Untitled sci-fi or fantasy novel
A novel in progress that will be either science fiction or fantasy; the genre choice is not yet decided, though the author expects to lean toward one genre for the final book based on past experience with genre crossover.
Abejora
Time tracking tool for freelancers and small teams. It adds access for AI agents so users' own agents can handle the repetitive parts of time tracking, with the core rebuilt to support change history and full undo/redo so control stays with the user. Runs on Elixir and Phoenix LiveView in a Kubernetes cluster of Talos instances.
Vaava
This app provides end-to-end encrypted data sync between connected apps and a WebRTC-based baby monitor feature that streams video and audio between two phones; recent work focuses on sync reliability and monitor stability, validated with reproducible multi-device test setups.
Fika Lingo
This app offers language and vocabulary practice exercises as a Duolingo replacement, including matching-words practice and other exercise types; practice generation runs on-device with a local LLM, and users can supply their own topics such as "Words that relate to Hacker News". It currently requires English as the counterpart language, and LFM model finetuning is being explored to improve the local practice generation.
MacroCodex
A free, ad- and subscription-free weight loss app that estimates daily total calorie burn using a sensorless adaptive TDEE (total daily energy expenditure) tracking technique, which the author says is more accurate than wearables. It runs as a PWA on Android, iOS, and any other supporting platform, and includes a community of 2,000+ members.
Symbiote
A beta, ad- and subscription-free Android workout app that offers "smart progression" features similar to Alpha Progression or MacroFactor Workout and lets users run any training program, similar to Boostcamp.
CalorieCodex
A beta Android app for AI-powered photo calorie tracking, with many features designed to make logging food each day very fast.
Banquish
A web app that lets users and AI agents put exact pieces from any websites they need onto a single screen. The pieces are live and interactive like normal web browser content rather than static screenshots.
Sports Similarity Explorer
A sports data site that lets you see which of today's games are most similar to games in the sport's history, with clickable detail views for individual games. It also includes the 'Sports Zodiac' and a 'Play the Years' timeline view of how the years go by, where eras like the war years, lockouts, and the pandemic stand out clearly in the data.
Ember
This day planner app treats schedules as dynamic instead of fixed: when a task is moved or its duration changes, everything after it shifts later and flows around fixed items like meetings, avoiding manual replanning. It is currently web + Capacitor and is being rebuilt as a native Kotlin app, with full-duplex voice models being explored so tasks can be added or moved by conversing with an agent.
Search engine for indie game content creators
A small search engine for content creators who play and/or review indie games, written in C.
Niblet - Weaning Diary
A weaning diary app for parents to log the food their baby eats and any reactions (such as rashes), helping them spot patterns to discuss with their GP. It also provides guidance on nutrients, food variety, and how to serve foods, all sourced from the NHS and FSA.
Hale
An abstract distributed systems programming language that offers fine-grained control over resources while requiring developers to express their intent to the compiler rather than declaring machinery directly. Computations are situated within a recursive graph structure incorporating message broker semantics, giving the compiler a unified view of programs across arbitrary process boundaries. Structural abstractions enable effects and formal verification syntax so architectural decisions can be checked by the compiler. The infrastructure-aware compiler configures the environments applications deploy into, with the single language covering everything from individual memory allocations to distributed fleet deployments. It is close to v1, and a fully distributed inference-as-a-service application is being built with it, matching arbitrary hardware supply against arbitrary caller demand in real time.
Kumoss
An intent-based infrastructure platform that turns natural-language requests into infrastructure changes while keeping validation, compliance, and existing engineering workflows in the loop. Developers can request any infrastructure need in a web portal, and the request is automatically fulfilled following organization standards defined by the platform team.
Tuppence
This platform provides online payment rails for businesses, developers and agents, letting users accept card payments at 0.79% (UK), earn 0.89% back on all card spend with no caps, and get paid out to their bank. It includes a store builder, expense management, payment links, direct debits, bookings, and a 'connect' platform for rolling payments out to marketplace businesses, with a UK-manufactured point-of-sale card reader for in-person payments. Roadmap items include ticketing and a 'treasury' feature offering 4% yield, FDIC/FSCS insurance, multi-currency fiat and stablecoin balances (USD, EUR, GBP, OUSD, USDC) with bank account numbers, positioned as a business layer on top of Stripe, Adyen and Checkout.com. It does not charge SaaS fees or lock users into contracts, and is built as a TypeScript monorepo (Ts.ED/Express, Postgres, React, React Native) with SDKs for Node, Python, iOS, Android, React Native and WordPress plus an MCP server and agent tools, hosted on Google Cloud Run and Cloud SQL.
Seedeo
An AI-powered website that generates engaging AI videos for social media, used to promote the site itself and expand its content library.
Thesoapbox.email
An email lottery social experiment in which each day a new subscriber is drawn to email the entire subscriber list, exploring what people do when suddenly given enormous reach.
Personal AI learning platform
A personal AI learning platform built on recursive self improvement that delivers tailored content to push the user's boundaries and unify their learning; currently not public.
Open-source personal expense tracker (expense-tracker)
An open-source personal expense tracker that registers tickets by sending them to a Telegram bot and reconciles them against uploaded bank statements. Data ingestion is built first, with reports and additional features planned later, and the design targets the lowest possible usage friction. Bank statement parsing leverages AWS Textract, Bedrock, and BDA, while ticket parsing uses AWS Textract plus parsing rules.
TaggedSync
An Obsidian plugin that converts handwritten reMarkable tablet notes into searchable text, with handwriting recognition that can run locally on a Mac. It also sends highlights and margin notes from the tablet to Readwise.
Arcaide
A web tool that visualizes the architecture of your code, including code written by LLMs.
RapidCAM
CAM web app for CNC work that already supports 2.5D CNC, laser, and rotary axis toolpaths, and is adding tufting support for CNC tufting makers.
JustFax Online
Web-based online faxing service (SaaS) that recently gained new features, improvements to fax routing, and admin tooling for analyzing traffic and usage patterns.
Beancount TUI
Terminal user interface built on top of beancount for plain-text accounting, customized to fit the builder's personal needs and business.
