# Development Centre: Work Becoming Products > Work on its way to becoming a product, across the development focus areas: what each record does today, how mature it is, and where it is heading. - Record count: 17 - Source: https://muhammetsafak.com/labs/ - Language: en-US - Author: Muhammet Şafak --- ## All focus areas - **AI and AI-assisted development** (4) — Where the LLM enters the development loop: code review, static analysis mixed with models, deterministic filters instead of prompts. - **Distributed systems & messaging** (1) — Queues, outbox, idempotent consumption and language-agnostic message contracts. - **Developer tooling & CI** (1) — CLIs, architecture boundaries enforced at build time, automation that measures code health. - **Automation & data pipelines** (2) — Scheduled jobs, integration pipelines and operational data flows: collection, transformation and timing. ## All records ### A 4X that ends in one sitting: the constraint chose the scope - A dice-free strategy core that resolves 480 hexes in 60 turns and runs offline in the browser; it shipped as Regnarium. - What it does today: Runs a full 4X match on a 480-hex map in at most 60 turns; rules, map generation and the opponent AI live in one pure TypeScript core, and combat rolls no dice. Anyone with half an hour and an appetite for strategy can open it in a browser. - State: Became a product - Form: Web - Started: 2026-09-09 - Left Labs: 2026-09-13 - https://muhammetsafak.com/labs/regnarium-lab/ - Markdown: https://muhammetsafak.com/labs/regnarium-lab.md ### Building a puzzle that never rolls a die: in SilkWard every move produces the same outcome - A deterministic puzzle on a node-and-edge board, offline-first; one TypeScript core feeds 36+6 levels to both web and mobile. - What it does today: Lets the player solve 36 levels + 6 hidden levels on a node-and-edge board through fully deterministic moves, with no luck or reflexes involved; a single TypeScript core drives both the web (PWA) and mobile (iOS/Android) client at once.

Teams where production access sits with one person can run it today. - State: Became a product - Form: Open-Source, Web - Started: 2026-09-06 - Left Labs: 2026-09-08 - https://muhammetsafak.com/labs/queryproxy-lab/ - Markdown: https://muhammetsafak.com/labs/queryproxy-lab.md ### Serving the documentation of dozens of projects from one server - A multi-tenant documentation server that gives every project its own MCP endpoint and keeps the documents on your own machine. - What it does today: Makes a project's folder, git repository, Obsidian vault or Notion workspace searchable behind a single MCP endpoint, so an agent reaches the documentation without the data going to a third party. Anyone who can run Docker can host it and manage it from the dashboard. - State: Became a product - Form: Open-Source, Web - Focus: AI and AI-assisted development - Started: 2026-08-19 - Left Labs: 2026-09-17 - https://muhammetsafak.com/labs/contextator-lab/ - Markdown: https://muhammetsafak.com/labs/contextator-lab.md ### Letting an application send RAG requests without ever holding a provider key - A self-hosted Go gateway between your application and the providers: one OpenAI-compatible API, with RAG context injected into every request. - What it does today: Lets an application talk to one OpenAI-compatible endpoint while a project's configuration decides which model the request reaches and, when a document store is linked, which documents it draws context from. Anyone who does not want provider keys spread across applications, and wants spend capped per project, can run it on their own server. - State: Became a product - Form: Open-Source, Web - Focus: AI and AI-assisted development - Started: 2026-08-19 - Left Labs: 2026-09-18 - https://muhammetsafak.com/labs/ragmux-lab/ - Markdown: https://muhammetsafak.com/labs/ragmux-lab.md ### academia.sh: can theory and a real field problem live in the same lesson? - A publicly open, free-to-read, text-first learning platform that holds textbook theory and problems actually met in the industry inside a single lesson flow. - What it does today: Live as a learning platform whose lessons are free to read without signup: the curriculum–course–topic–lesson hierarchy, full-text search and progress tracking work, while the course-end exam, verifiable certificates and the study assistant sit in a Pro tier. Anyone who wants to read the computer-science curriculum can use it today. - State: Became a product - Form: Web - Started: 2026-08-13 - Left Labs: 2026-09-23 - https://muhammetsafak.com/labs/academia-lab/ - Markdown: https://muhammetsafak.com/labs/academia-lab.md ### Qurandia: matching two datasets whose numbers disagree, by fingerprinting the text - An open, free resource for reading, understanding and learning the Qur'an, gathering Qur'an- and hadith-centred research under one roof. - What it does today: Live as a free, open resource for reading and searching the Qur'an and hadith side by side; letter-level fingerprint matching gives 91–99% coverage across the hadith collections.

Anyone using Claude Code who needs to triage a production error can install the skill. - State: Halted - Form: Open-Source - Focus: AI and AI-assisted development - Started: 2026-07-01 - Left Labs: 2026-09-23 - https://muhammetsafak.com/labs/sentryfixer-lab/ - Markdown: https://muhammetsafak.com/labs/sentryfixer-lab.md ### Devrazzi: filtering developer news through layers of models - A content pipeline that screens software and AI news locally with Ollama, hands survivors to larger models, and publishes Turkish and English syntheses. - What it does today: Filters software and AI news through a local Ollama pass and hands the upper layers to the larger models, then writes and publishes the TR/EN synthesis on its own; the web and App Store builds are live. Anyone who wants their daily developer news in one feed can read it. - State: Became a product - Form: Web, Mobile - Focus: Automation & data pipelines - Started: 2026-06-28 - Left Labs: 2026-09-23 - https://muhammetsafak.com/labs/devrazzi-lab/ - Markdown: https://muhammetsafak.com/labs/devrazzi-lab.md ### Two languages sharing one queue without the serialization lock-in - A frozen JSON envelope in place of language-specific serialization; it became BabelQueue, a polyglot queue standard. - What it does today: The frozen JSON envelope has four languages — PHP, Python, Go, Node.js — reading the same bytes, with no sidecar and no broker plugin. Teams running a polyglot queue can pick up the spec and the SDKs today. - State: Became a product - Form: Open-Source - Focus: Distributed systems & messaging - Started: 2026-03-01 - Left Labs: 2026-06-15 - https://muhammetsafak.com/labs/babelqueue-lab/ - Markdown: https://muhammetsafak.com/labs/babelqueue-lab.md ### Screen lock by Bluetooth proximity: present/absent is not enough - A Bluetooth proximity lock experiment that locks the machine when the paired device walks away; shipped as SignalLock, development has stopped. - What it does today: Locks the macOS screen when the device you carry moves away; the call rests on a proximity assessment rather than a raw present/absent signal, so fluctuation no longer produces false locks. The menu-bar app is published and ready to install. - State: Halted - Form: Open-Source, Desktop - Started: 2026-03-01 - Left Labs: 2026-05-20 - https://muhammetsafak.com/labs/signallock-lab/ - Markdown: https://muhammetsafak.com/labs/signallock-lab.md ### Local code review without letting the diff leave the machine - A provider-agnostic Go CLI that has a model review my diff without the diff leaving the machine; it became CommitBrief. - What it does today: Reviews code locally, with the diff never leaving the machine; the `Provider` interface lets Anthropic, OpenAI, Gemini and Ollama plug into one contract.
