Add Features for your GPT Engineer 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 GPT Engineer projects and know exactly what to look for.
Add Features issues we find in GPT Engineer apps
These are real add features problems we see in GPT Engineer projects during our audits.
Incomplete feature implementations
Features that look complete in the UI but don't actually work end-to-end. Buttons that don't submit, forms that don't save, and links that go nowhere.
Missing error boundaries
A single component error crashes the entire application. No error boundaries or fallback UIs to gracefully handle failures.
Monolithic file structure
All code in a handful of large files with no clear separation between features, pages, or layers.
What our add features covers
Everything included when we add features your GPT Engineer project.
Payment integration
Stripe subscriptions, one-time payments, invoicing, refunds, and billing management.
User management
User profiles, account settings, role-based permissions, teams, and admin dashboards.
Email & notifications
Transactional emails, in-app notifications, email digests, and notification preferences.
Search & filtering
Full-text search, faceted filtering, sorting, and pagination for data-heavy applications.
File handling
File uploads, image processing, document generation (PDFs, CSVs), and cloud storage.
Third-party integrations
Connecting your app with Slack, Zapier, Google Workspace, CRMs, and other business tools.

Frequently asked questions
Can you add features a GPT Engineer app?
Yes. We work with GPT Engineer projects regularly and understand the specific patterns it produces. Our add features service is tailored to address the issues common in GPT Engineer-generated code.
What add features issues are specific to GPT Engineer?
Common add features issues in GPT Engineer apps include: incomplete feature implementations, missing error boundaries, monolithic file structure. We identify and fix all of these.
How long does a add features take for a GPT Engineer project?
Typically 2-5 business days depending on codebase size. Start with our code audit ($19) to get a clear picture of what needs attention, then we'll scope the add features work with a fixed quote.
Do I need a code audit before add features for my GPT Engineer app?
We recommend it. The audit ($19) gives us a complete picture of your GPT Engineer project's issues so we can scope the add features work accurately. You get a prioritized report and a fixed quote with no surprises.
