deepseekdsh

Install, fix, and extend DeepSeek Harness

DeepSeek Harness (DSH) is an open-source agent harness for working with AI models. It helps you connect a model provider, use local files, manage sessions, set approval boundaries, and extend the setup with plugins, MCP, skills, subagents, and workflows. The site focuses on getting you started fast, fixing specific errors, and exploring extensions. It also includes guides for Windows, macOS, and Linux, plus a web UI workflow for running tasks in a local workspace. A community desktop wrapper is available for people who prefer a desktop app over terminal setup.

FATHER

A Mac dashboard for site traffic, deploys, uptime, and SEO

Father is a mission-control dashboard for teams shipping on Vercel. Connect your account and each project appears with live traffic, deploys, uptime, and PageSpeed scores. Google Search Console and Bing show clicks, rankings, and indexing. SSL and domain renewals get countdown timers, and failing GitHub checks are flagged. When a build fails, the F in the menu bar turns red and a notification fires, even with the window closed, so you know a site is down before your clients do. Your tokens stay on your Mac. It is a one-time purchase.

Results are organized into SEO, AI Visibility, and Fixes workspaces. You can track improvements and regressions over time, create agent-ready artifacts, connect coding agents through MCP, monitor uptime, and get weekly reports plus downtime alerts.

Turn a spare Mac display into a retro system dashboard!

Wokyintosh is a free, open-source macOS dashboard inspired by the classic Macintosh. It brings together a large clock and date, local weather, Apple Music and Spotify Now Playing with album artwork, and live CPU, RAM, SSD, and network stats. I built it for my Wokyis M5 Retro Dock Station after spending months looking for a dashboard I actually liked, even in paid apps.

chat-recall

Ctrl+F for every conversation you've had with an AI

Your team has done months of work with AI assistants. Claude Code, Codex, Cursor, and OpenCode each keep a full record of it in its own format, and none can read the others. Chat Recall reads what they wrote with one command and turns it into one searchable history. Passwords are stripped out before anything leaves your computer. Your assistant can search that history itself, so it stops asking what you decided last month. It also finds keys that leaked into old chats and checks which ones still work.
