Devin + Internal Tool

Built a internal tool with Devin?
We'll make it production-ready.

Internal tools don't face the public internet, but they often have access to sensitive business data — customer records, financial data, operational metrics. AI tools build internal dashboards quickly, but the security bar is still high because a compromised internal tool can expose your entire business.

Internal Tool challenges in Devin apps

Building a internal tool with Devin is a great start — but these challenges need attention before launch.

Access control

Who can see what? Internal tools need role-based access — finance sees revenue data, support sees customer data, engineering sees system metrics. AI tools build the dashboard but rarely implement granular permissions.

Data sensitivity

Internal tools often connect directly to production databases. A bug that deletes records or a missing auth check that exposes customer PII can have serious legal and business consequences.

Network security

Internal tools should be behind a VPN or protected network, not on the public internet. AI tools deploy to public URLs by default. Proper network configuration prevents external access.

Audit logging

When someone modifies data through an internal tool, you need to know who did what and when. This is essential for debugging, compliance, and accountability.

Data mutations

Internal tools often write to production databases — updating orders, modifying user accounts, issuing refunds. These operations need confirmation dialogs, validation, and audit trails to prevent costly mistakes.

What we check in your Devin internal tool

Access control — role-based permissions enforced server-side
Database security — read-only where possible, protected write operations
Network configuration — not publicly accessible, VPN or auth gateway
Audit logging — who did what, when
Data validation — confirmation for destructive operations
Authentication — SSO or secure login for all team members
Error handling — graceful failures that don't expose internal data

Common Devin issues we fix

Beyond internal tool-specific issues, these are Devin patterns we commonly fix.

highSecurity

Autonomous security decisions

Devin makes security-related decisions without human review — choosing auth strategies, setting permissions, and configuring access controls that may be inadequate.

highCode Quality

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.

mediumBugs

Workarounds instead of fixes

When Devin encounters an error, it sometimes adds workarounds that mask the root cause rather than fixing the underlying issue.

mediumPerformance

Inefficient retry patterns

Devin's debugging approach sometimes results in retry logic and fallback patterns that hide errors rather than resolving them, impacting performance.

Frequently asked questions

Can I build a internal tool with Devin?

Devin is a great starting point for a internal tool. It handles the initial scaffolding well, but internal tools have specific requirements — access control and data sensitivity — that need professional attention before launch.

What issues does Devin leave in internal tools?

Common issues include: autonomous security decisions, compounding architectural errors, workarounds instead of fixes. For a internal tool specifically, these issues are compounded by the need for access control.

How do I make my Devin internal tool production-ready?

Start with our code audit ($19) to get a clear picture of what needs fixing. For most Devin-built internal 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 Devin-built internal 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 internal tool projects, we provide a custom fixed quote after the audit — no hourly billing.
