DeepDeck

What it does

DeepDeck is an MIT-licensed macOS desktop built on DeepSeek Harness. It turns Cordis plugins into apps with their own windows, settings, Workspaces, and Agent Sessions. Use Hacker News Reader or Video Sherlock, ask the agent to modify local source, rebuild and hot-reload the result, then contribute useful changes through Git and PRs. Bring your own Codex or DeepSeek connection. No included model credits. Not an official DeepSeek product.

DeepDeck lets agents explore websites and save verified workflows as reusable WebMCP tools. Use existing tools or build new ones without teaching every click.

Workspaces, modes, models, and the prompt all fall into one natural flow. DeepDeck keeps existing Harness settings and extensions compatible; after guided first-run setup, it is ready for work. You set the goal. The Agent explores and uses the website, then saves verified workflows as WebMCP tools for future tasks. No need to teach it every click: existing products become easier for agents to work with. Create a new page and make the OpenAI logo. For this task, Figma Agent said it couldn't edit vector shapes or paths yet. DeepDeck + WebMCP completed it. A record of this task. DeepDeck used WebMCP alongside browser tools during execution. DeepDeck created a ginger cat with green eyes,…from deepdeck.getmegaportal.com

  We've built an Open Source plugin to make using AI easier for VFX2023 · deepmake.com · ▲34

  Hi, I’m Bryan Lyon, the CTO of DeepMake. We’re making plugins for VFX software suites (Right now we have a pre-release of our After Effects plugin ready) that enable you to use Open Source AI tools without leaving the workflow. It makes all the AI tools work just like another plugin in the VFX software. In the past, I worked on VFX adjacent AI and was more than once asked to make AI tools easier to use so the VFX experts could use them. In many cases my job was little more than making it easy to install and make sense to use. After writing dozens of “one-off” scripts that made an AI tool…

  DeepSeekGUI – A Windows desktop client for DeepSeek's coding agentAug 2026 · github.com · ▲5

  Hi HN, I built a desktop client for DeepSeek Harness (DeepSeek's open-source coding agent). V1 wraps the official Harness Web UI in an Electron shell with some desktop additions — installer, system tray, built-in browser panel (visible Edge, so you can watch the agent browse), and a sandboxed terminal. One-click install, just need an API key. V2 is in development — replacing the upstream Web UI with a custom workbench built for desktop. Source available under PolyForm Perimeter. Would love feedback on what you'd want from a desktop coding agent client.

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
