Debugging Production Bugs Without a Staging Environment

The staging reality for solo founders

Most solo founders either don't have a staging environment or have one that doesn't match production closely enough to be useful. This means debugging often happens against live production data.

The risks of prod debugging

You might accidentally modify user data, expose debug logs to users, or deploy a half-finished fix. These are real risks that can be mitigated with discipline.

Safe production debugging techniques

• Feature flags — deploy the debug version but only enable it for your own account
• Debug endpoints behind auth — create debug routes that require admin authentication
• Read-only investigation first — before making any changes, fully understand the problem
• Database migrations on a copy first — never run schema changes on live data without testing

How monitoring reduces the need for staging

Good error monitoring gives you the information you need without having to reproduce the bug. ProdFix captures: stack trace, user state, browser context, network requests, and a session replay. Often you can fix the bug without ever reproducing it.

The Cursor + MCP workflow for prod bugs

With ProdFix MCP connected to Cursor: open Cursor, ask "show me the full context for this error", get the complete stack trace + user state, ask Cursor to fix it, review the diff, deploy. No staging needed for most bugs.
