sc-screen-recorder
Browser screen recorder with canvas composition, teleprompter, live annotations and talking-head overlay.
I give my side projects away for free because I have a $job to pay for the roof over my head, food, etc. and don't feel the need to make more money from my hobby work.
I create my side projects in the first place because I like to prove to myself that it is possible to do mad stuff in the browser - like a screen recorder with canvas composition, teleprompter, live annotations and talking-head overlay[1]. Or an SVG-inspired image filter builder for local batch application to images (still a WIP but almost there)[2].
It doesn't cost me any money to host the results, so: why not?

local-mcp-releases
LMCP — Give your AI native access to your apps. 189 tools across macOS and Windows. Mail, Calendar, Teams, OneDrive, Outlook, Google Drive and more. 100% local.
Project mention: Show HN: Local MCP – give Claude, Cursor and ChatGPT access to your whole Mac | news.ycombinator.com | 2026-06-03AI assistants are brilliant in a vacuum and blind to your actual life. They'll write the email — but they've never seen the thread. They'll plan your day — if you paste in your calendar. Two things are missing: the full context of what you're working on, and the ability to actually carry out the process end to end.
Local MCP gives an assistant both. It connects Claude, Cursor or ChatGPT to the apps you live in — Mail, Calendar, Contacts, Messages, Teams, Slack, WhatsApp, Notes, Reminders, OneDrive, Outlook, your files, and Word/Excel/PowerPoint — so it starts with the full context already loaded and can run a whole process in one go, not just answer questions about it. "Catch me up and prep tomorrow" becomes: it reads the thread from your boss, checks your calendar, drafts the reply, files a doc, and sets the reminder — done, not described.
What makes it different from cloud connectors and plugins:
1. It's 100% local. Your mail, messages and files never leave your machine — no cloud processing, no tokens, no API keys, no company in the middle.
2. It reaches what cloud tools can't. Most integrations only touch services with a public API and an OAuth setup. Local MCP works with the apps already on your machine — so it can read your iMessages, your Teams history, your WhatsApp, your local files: context no API-based integration can hand an AI. One install, nothing to configure per service.
It's past the experiment stage: a few hundred people have it installed, and the heavy users are running thousands of operations across their stack, in a dozen countries. Works on macOS and Windows.
