Adding Features to Your Copilot Workspace App

Copilot Workspace handles in-repository code changes well but doesn't manage external dependencies, infrastructure changes, or repository configuration changes. New third-party services, cloud resources, and significant dependency additions require manual setup

Implementing a new feature across multiple files with tests included. Migrating from one library to another across the codebase. Adding consistent error handling to an entire module. Implementing a spec or issue that requires changes to several services

Almost every SaaS app needs payment processing. Stripe is the standard — it handles credit cards, subscriptions, invoices, and payouts. The key pieces: a checkout flow for collecting payment, webhooks to update your database when payments succeed or fail, and a customer portal for managing subscriptions. Copilot Workspace might generate a basic checkout page, but the webhook handling and subscription lifecycle management usually need to be built by hand.

Your app needs user accounts with secure login. The easiest options: NextAuth (for Next.js), Supabase Auth, or Clerk. These handle email/password login, social login (Google, GitHub), password resets, and session management. Don't build auth from scratch — the security implications are too complex for a first implementation.

Transactional emails — welcome emails, password resets, order confirmations — require an email service provider. Resend is the simplest to set up, SendGrid is the most established, and Amazon SES is the cheapest at scale. You'll need email templates, a sending service, and proper DNS configuration (SPF, DKIM) so your emails don't land in spam.

If a feature requires deep technical expertise (payment compliance, data privacy, real-time systems), it's faster and safer to get professional help than to iterate with AI tools. Our team adds features like these to Copilot Workspace apps every week — we know the patterns and the pitfalls.
