Add features to your Devin app
AI tools get you 80% of the way, but the remaining 20% - payments, real-time features, complex workflows, third-party integrations - is where things get hard. We build the features that require experienced engineering, integrating them cleanly into your existing codebase. We specialize in Devin projects and know exactly what to look for.
Add Features issues we find in Devin apps
These are real add features problems we see in Devin projects during our audits.
Compounding architectural errors
When Devin makes an early architectural mistake, it builds subsequent features on top of it. By the time you notice, the issue is deeply embedded in the codebase.
Workarounds instead of fixes
When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.
Inconsistent dependency management
Devin adds dependencies as needed during development, sometimes duplicating functionality already available or using conflicting library versions.
Missing documentation for complex flows
Devin builds complex multi-step processes without documenting the logic, making it hard for humans to understand or modify later.

Frequently asked questions
Can you add Stripe payments to my Devin app?
Yes. We integrate Stripe with proper checkout flows, webhook handling, subscription management, and error handling. Devin usually generates a basic Stripe integration that misses edge cases - we build it production-ready.
Can you add user authentication to my Devin app?
Yes. We set up auth with Supabase, Firebase, or Clerk - including signup, login, password reset, OAuth (Google, GitHub), and role-based access control. We make sure protected routes are actually protected.
How much does it cost to add features to a Devin app?
Feature development starts at $300 per feature. Simple features (contact form, email notifications) cost less. Complex features (payment system, admin dashboard) cost more. We scope each feature with a fixed quote.
Can you finish features that Devin started but didn't complete?
Absolutely. This is one of our most common requests. Devin often generates features that look right but don't handle edge cases, error states, or real-world data. We pick up where Devin left off and make it production-ready.
