Fine.dev + Internal Tool

Built a internal tool with Fine.dev?
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 Fine.dev apps

Building a internal tool with Fine.dev 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 Fine.dev 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 Fine.dev issues we fix

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

highBugs

Spec interpretation may differ significantly from intent

Fine.dev builds exactly what the specification says, not what you meant. Ambiguous specs lead to technically correct implementations that miss the actual product requirement.

highSecurity

Cross-file changes may miss security implications

When Fine.dev generates features spanning multiple files, security-sensitive changes — new endpoints, auth checks, data access patterns — are spread across the PR without a consolidated security review surface.

mediumTesting

Generated tests may not cover real-world edge cases

Fine.dev writes tests for the happy path and obvious failure cases from the spec. Edge cases not explicitly mentioned — concurrent requests, null inputs, rate limits — are frequently untested.

mediumBugs

Cross-file changes introduce inconsistencies

Large implementations touching many files accumulate subtle inconsistencies — type assumptions that don't hold across modules, different error handling patterns in different files.

Frequently asked questions

Can I build a internal tool with Fine.dev?

Fine.dev 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 Fine.dev leave in internal tools?

Common issues include: spec interpretation may differ significantly from intent, cross-file changes may miss security implications, generated tests may not cover real-world edge cases. For a internal tool specifically, these issues are compounded by the need for access control.

How do I make my Fine.dev internal tool production-ready?

Start with our code audit ($19) to get a clear picture of what needs fixing. For most Fine.dev-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 Fine.dev-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.
