Built a developer tool with Cursor?
We'll make it production-ready.
Developer tools face the most technically demanding audience there is — other developers. They'll inspect your source code, stress-test your API, and publicly criticize performance issues on Twitter. AI tools can scaffold a CLI, dashboard, or API wrapper quickly, but developer tools need exceptional error messages, comprehensive documentation, and rock-solid reliability because your users know exactly how software should work.
Developer Tool challenges in Cursor apps
Building a developer tool with Cursor is a great start — but these challenges need attention before launch.
Error messages and developer experience
Developers expect error messages that tell them exactly what went wrong, why, and how to fix it. AI-generated tools return generic 'Something went wrong' messages or raw stack traces. Good DX means every error is actionable and every edge case has a helpful response.
API design and consistency
Developer tools live or die by their API surface — whether REST endpoints, CLI arguments, or SDK methods. Naming must be consistent, behavior must be predictable, and breaking changes must be versioned. AI tools generate functional but inconsistent APIs that frustrate developers.
Documentation and examples
Developers won't use your tool if they can't figure it out quickly. You need API reference docs, getting-started guides, code examples in multiple languages, and a changelog. AI tools build the tool but not the documentation ecosystem around it.
Performance and latency
Developer tools are often in the critical path of other developers' workflows — slow API responses, laggy CLIs, or unresponsive dashboards directly waste their time. Every millisecond matters. AI-generated tools have unoptimized database queries and no caching.
Authentication and API key management
Developer tools need API key generation, key rotation, scoped permissions per key, usage tracking, and rate limiting. AI tools implement a single hardcoded API key or basic bearer tokens without any key lifecycle management.
Webhook and integration reliability
If your tool sends webhooks or integrates with other services, deliveries must be reliable — with retry logic, delivery logging, signature verification, and a way for users to test and debug integrations. AI tools fire-and-forget webhooks with no reliability guarantees.
What we check in your Cursor developer tool
Common Cursor issues we fix
Beyond developer tool-specific issues, these are Cursor patterns we commonly fix.
Exposed API keys in client code
Cursor often places sensitive keys and secrets directly in client-side components or .env files without the NEXT_PUBLIC prefix distinction, making them accessible in the browser.
Missing input validation on API routes
Server actions and API routes generated by Cursor frequently accept user input without sanitization or schema validation, opening the door to injection attacks.
Unhandled async errors
Cursor wraps code in try/catch inconsistently. Failed API calls, database queries, and file operations often crash the app silently or show raw error messages to users.
Race conditions in state management
Multiple rapid state updates or concurrent API calls cause stale data, UI flickers, and inconsistent behavior — especially in forms and real-time features.

Frequently asked questions
Can I build a developer tool with Cursor?
Cursor is a great starting point for a developer tool. It handles the initial scaffolding well, but developer tools have specific requirements — error messages and developer experience and api design and consistency — that need professional attention before launch.
What issues does Cursor leave in developer tools?
Common issues include: exposed api keys in client code, missing input validation on api routes, unhandled async errors. For a developer tool specifically, these issues are compounded by the need for error messages and developer experience.
How do I make my Cursor developer tool production-ready?
Start with our code audit ($19) to get a clear picture of what needs fixing. For most Cursor-built developer tools, the critical path is: security review, then fixing core flow reliability, then deployment. We provide a fixed quote after the audit.
How much does it cost to fix a Cursor-built developer tool?
Our code audit is $19 and gives you a complete report of issues. Fixes start at $199 with our Fix & Ship plan. For larger developer tool projects, we provide a custom fixed quote after the audit — no hourly billing.
