Add a supported project folder. Decker finds its services and keeps the working URL, status, and logs together. As projects add up, return to one workspace instead of tracking terminals or ports.
See where each service is running, which URL opens, and what failed without reconstructing terminal history.
Scene 01 / scattered projects
One uses npm, another uses Python, and another contains multiple services. Returning later means remembering commands, ports, and terminal windows.
Decker keeps saved projects, detected services, current status, and local URLs in one place.

Scene 02 / unknown URL
A terminal printed a URL, but the browser cannot reach it. Now you have to determine whether the service is running and where it actually opened.
With Decker, the working URL, service status, and logs stay together.

Scene 03 / conflicting ports
The first service already owns port 3000. Starting another project now means finding the process, changing configuration, or cleaning up terminals.
For supported services, Decker assigns an available port without terminating the process already using the old one.
You just wanted to see the dashboard. Now you are trying to understand why the port is conflicting.
Decker reads supported project files and gives you one place to run and inspect each project's services.
Choose the project folder already on your computer.
See the frameworks, services, and ports Decker detected.
Start a service, open its working URL, and check status and logs.
With more saved projects, switch from the sidebar and see which services are running.

Created with Claude, Cursor, or Codex, downloaded from GitHub, handed over by someone else, or written by you—the project files are what matter. No AI connection is required.
Starter runs and inspects one saved local project on one device. Lifetime adds unlimited saved projects, more devices, public previews, supported Vercel deploys, and GitHub backups.
Run and inspect one local project on one device.

Decker is a desktop app for running and managing supported local projects. Add a project folder, start its services, open the working URL, and check status and logs in one place.
No. Decker works from supported project files regardless of whether they were created with AI, downloaded, handed over, or written by you.
Decker is available on macOS 14 or later and Windows. Linux support is on the way.
Yes. Your first local project is included on 1 device. Lifetime unlocks unlimited projects, preview links, supported Vercel deploys, GitHub backup, integrations, and up to 3 devices.
Decker can run supported Next.js, React, Vue, Nuxt, Svelte, Remix, Astro, Vite, Express, NestJS, FastAPI, Flask, Django, Streamlit, Flutter, and other detected projects. Vercel Deploy is available only for Next.js, Vite-based React, Vue, or Svelte, Nuxt, Astro, Remix, SvelteKit, and Create React App services.
Sign in on rundecker.com and download the macOS or Windows installer from your Dashboard. Open Decker, scan a project folder locally, then sign in in the app when you save it and activate the device.
Decker needs the runtime required by the project, such as Node.js for React or Next.js and Python for Flask or Django. Decker does not replace the project runtime itself.
Local scanning and running stay on your computer. Share exposes the running local service only when you start it. Deploy and GitHub backup upload filtered project files only after you explicitly confirm those actions.
Starter access works on 1 device and can save 1 local project. A Lifetime license works on up to 3 devices and unlocks unlimited projects, preview links, supported Vercel deploys, integrations, and GitHub backup.

Start with one supported project. See its working URL, status, and logs, then upgrade when you need more projects, public previews, supported deploys, backups, and devices.
