A cross-platform control plane for async, agent-driven software delivery.

• Run multiple background agent sessions in parallel across repositories
• Launch agent-based requests from existing issues and PRs
• Mobile and desktop triage views optimized for fast issue and PR decisioning
• Swipe actions for close, merge, create PR, and skip-to-tail workflows
• Agent-powered Assess flows for issue necessity and PR merge decisions
• Automated PR review
• Activity panel showing all agent sessions and actions
• GitHub OAuth sync with scope controls (user:, org:, repo:)
• Powered by Devin

Lysium does not store Devin credentials in browser storage. Users enter their Devin API key, org ID, and GitHub scope in the app UI. Credentials are validated and stored server-side in signed HttpOnly cookies, and Devin API calls are proxied through the server.

• Node.js 18+
• A GitHub OAuth App
• A Devin API key (cog_...) and organization ID

npm install

cp .env.example .env.local

Fill in .env.local:

1. Go to GitHub Settings → Developer settings → OAuth Apps → New OAuth App
2. Set the callback URL to http://localhost:8787/api/github/oauth/callback
3. Copy the client ID and secret into .env.local

npm run dev:all

This starts both the local API server (port 8787) and Vite (port 5173). Open http://localhost:5173, sign in with GitHub, then connect Devin from the startup auth panel (or Settings).

• On first GitHub OAuth sign-in, scope defaults to user:<your-login>.
• You can set scope to user:<username>, org:<org>, or repo:<owner/repo>.
• If you enter a value without a prefix (for example acme), Lysium treats it as org:acme.
• OAuth is requested with repo scope, so private repositories in your selected scope can be included.

Go to vercel.com, create a new project, and import your repository.

Go to your project → Settings → Environment Variables and add:

Set the callback URL in your GitHub OAuth App to:

https://your-app.vercel.app/api/github/oauth/callback

Vercel deploys automatically on pushes to your main branch. Users connect GitHub and enter Devin credentials in the app UI after deploy.

• Connect GitHub via OAuth to sync open issues and pull requests from your configured scope
• Swipe right on an issue to have Devin open a pull request
• Swipe left on an issue to close it on GitHub
• Swipe right on a pull request to merge it (or enroll auto-merge if checks are pending)
• Swipe left on a pull request to close it without merging
• Swipe down on issues or PRs to skip and move them to the tail
• Use Assess to have Devin evaluate issue necessity or PR merge decisions
• Use Review to open Devin review sessions for PRs when available
• Use the Code tab to start a Devin implementation request (including “Devin’s machine” mode)
• Use Leave Comment to post manual PR comments (with optional Devin mention tagging)
• Track everything in Activity, split into Sessions and Actions
