Building Developer Tools & DX Products

Diagnostic Summary

"Developers waste significant time on repetitive debugging workflows: switching between browser consoles, authentication inspectors, API testing tools, and performance monitors. The cognitive overhead of context-switching between tools slows down development velocity. There's a need for integrated, privacy-first developer tools that consolidate these workflows into a single interface."

The Solution Strategy

Max built DevConsole — a local-first developer tool that runs entirely on-device for private-by-design debugging. It consolidates auth inspection, state modification, API testing, and performance monitoring into a single UI embedded in the developer's application. The key insight: developer tools should be ambient, not intrusive — available when needed without disrupting the development flow.

Critical Success Factors

  • Developer tools should be local-first and privacy-by-design — sensitive debugging data (auth tokens, API keys) should never leave the developer's machine
  • The best developer tools reduce context-switching — consolidating auth, state, API testing, and performance into a single surface saves more time than any individual tool
  • Embedding developer tools in the application's own UI creates a more natural debugging experience than separate browser extensions or standalone apps
  • Developer adoption follows the same principles as design system adoption: make it trivially easy to integrate, and developers will use it

Frequently Asked Questions

What is DevConsole and how does it work?
DevConsole is a local mission control for web apps built by Max Fritzhand. It lets developers inspect auth state, modify application state, test APIs, and monitor performance — all without leaving their own UI. It runs 100% locally for privacy-by-design debugging, requiring no external services.
How does Max Fritzhand approach developer experience (DX)?
Max designs developer tools with the same product thinking he applies to consumer products: understand the workflow, reduce friction, measure adoption, and iterate. DevConsole emerged from his own frustration with switching between multiple debugging tools — he built what he wished existed.
Can Max Fritzhand build custom developer tools for teams?
Yes. Beyond DevConsole, Max has built internal developer tools including automated test frameworks, CI/CD pipelines, reporting dashboards, and design system documentation. He understands that developer tools are products — they need good UX, clear documentation, and frictionless adoption.
