🎨 Best DeepSeek Harness Design Plugin. The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes, landing pages, dashboards, slides, images & video — real files, HTML/PDF/PPTX/MP4 export. 🤖 Claude Code / Codex / Cursor / DeepSeek Harness / OpenCode & 20+ CLIs via BYOK.
How open-design is put together
OpenDesign is a local-first, agent-native design product distributed as a pnpm monorepo. It detects installed coding-agent CLIs (Claude Code, Codex, DeepSeek Harness, Cursor, etc.), runs composable design skills and `DESIGN.md` design systems, and streams generated artifacts (web/mobile prototypes, decks, images, documents, HyperFrames) into a sandboxed iframe preview. The core is a Node/TypeScript daemon exposing an Express server and MCP integration, an Electron desktop shell, a Next.js web UI, and an Astro landing page, plus a Chrome/Figma clipper and Nix/Docker/Helm deployment tooling. Data flows: a brief and design system feed a locally-launched agent runtime whose output is captured, previewed, and exported to HTML/PDF/PPTX/MP4.

A lighter week of assorted fixes across the web app, daemon, and bring-your-own-key setup, plus a new prompt discovery feature.
Over the past five weeks the team steadily polished Open Design's editor, preview, and onboarding experience while running a series of pricing and marketing campaigns — most prominently a big DeepSeek Harness launch in mid-August. Recent effort has shifted toward stabilizing the daemon and runtimes that connect to various AI coding agents, tidying the pricing and landing pages (including retiring the 'Go' plan promo), and rolling out 'OD Next', a new default design strategy. Throughout, the work is heavily weighted toward small reliability fixes and UI refinements rather than large new features.
Week by week
2026-08-24A steady week of preview and UI reliability fixes alongside making the new 'OD Next' design engine the default and trimming the pricing page.latest6 changes
Feature
OD Next becomes the default design engine
The newer 'OD Next' design strategy is now on by default, with an app-config switch letting it be turned on or off.
Fix
Cleaner slash command menu
The pop-up command palette in the chat box no longer squashes its rows when the list gets long.
Feature
Simplified pricing page
The pricing and landing pages were streamlined and the sold-out 'Go' plan and its promo banner were marked and removed.
Fix
More reliable slide-deck previews
Several fixes stabilize how presentation previews are measured and displayed, including retrying failed image captures during PowerPoint export.
Feature
Dynamic Coding Plan models
The list of available coding models now loads dynamically rather than being hardcoded.
Fix
Better handling of external AI agents
Fixes let the app connect more gracefully to various third-party coding tools instead of failing or retrying uselessly.
2026-08-17A large cleanup week focused on aligning the pricing and landing pages with subscription state and polishing the web interface.6 changes
Fix
Pricing page matches what you actually have
Numerous fixes make plan buttons, badges, and balances reflect the user's real subscription — disabling current or lower plans and correctly labeling unlimited models.
Feature
Calmer, refreshed landing page
The homepage first screen was made calmer and less pushy, with a redesigned header, smaller call-to-action buttons, and localized event recap pages.
Chore
Community links consolidated to Discord
Old Feishu group entries were retired and every 'join the community' button now points to Discord.
Feature
DeepSeek vision unlimited access
Added unlimited access to DeepSeek's vision capabilities as a pricing perk.
Fix
Tidier message center and account menu
The notification list was flattened and the software updater was separated from the account panel for clarity.
Feature
Faster, smarter build pipeline
Continuous-integration improvements add global change-detection so unaffected work can be skipped, and surface build failures as PR comments.
2026-08-10The big DeepSeek Harness launch week, adding full support for the new agent plus one-click installers and a curated plugin collection.6 changes
Feature
DeepSeek Harness support
Added full support for the DeepSeek Harness coding agent, including one-click bootstrap installers and guided credential setup.
Feature
Curated DeepSeek plugin collection
Published a curated set of DeepSeek Harness design plugins with illustrated covers and a design tutorial and guide.
Feature
Reliable standalone HTML export
Projects can now be exported as self-contained HTML files that work on their own.
Fix
Steadier previews and workspace tabs
Fixes recover interrupted previews, remove letterboxing on deck previews, and drop deleted projects from open tabs.
Feature
Refreshed home and workspace controls
The home screen and preview workspace controls were refreshed, with creator identity shown on recent projects.
Refactor
Calmer collaboration syncing
Bounded runaway workspace-refresh activity so shared projects sync more smoothly.
2026-08-03A stabilization-heavy week hardening collaboration, preview recovery, and test reliability while launching a DeepSeek V4 Flash free-week campaign.6 changes
Feature
DeepSeek V4 Flash free-week campaign
Launched a free-week promotion for DeepSeek V4 Flash across the landing page and app, localized into 19 languages.
Fix
Sturdier cloud collaboration
Multiple fixes calm error storms and failed publishes when many people share and sync projects through the cloud.
Fix
Recovering previews and stale runs
Deck previews now recover when returning to a project tab, and stale completed design runs no longer replay on reload.
Refactor
Faster design file grids
Large design file grids now load lazily and only fetch thumbnails when needed.
Fix
Restored bring-your-own-key model switching
Users supplying their own API keys can again switch models from the home and composer pickers.
Chore
More stable automated testing
End-to-end tests were hardened against flakiness with better completion signals and right-sized test runners.

Fix
Steadier agent sessions
Daemon fixes keep stalled sessions moving and better isolate and complete runs from various coding agents.
Fix
Preserved browser preview state
The in-app browser preview now remembers its viewport and clears stale to-do items after a task continues.
Fix
Better dark-mode contrast
Off-state toggles are now easier to read in dark mode.
Feature
Local Open Design Cloud flow for Codex
Added a local integration flow connecting the Codex agent to Open Design Cloud.
