CLI Auth Debugger for Dev Tools
Build a diagnostics layer that detects why device-code and browser-based logins fail in WSL, VMs, and corporate environments. The product would classify failures into polling, proxy, clock, package-version, or network categories and provide immediate remediation steps.
Why this matters
You open your coding assistant in a Linux shell on Windows, complete the browser authorization, and expect to get back to work. Instead, the terminal waits forever, gives vague fetch failures, or never writes the token locally. You waste time testing VPN settings, proxy variables, package versions, and repo builds just to learn whether the issue is network-related, a timing bug, or a release regression. Existing tools assume the login flow is simple, but in managed laptops and virtualized environments it often is not. What you need is a tool that tells you exactly what broke and how to recover in minutes, not hours.
- · Built for Developers and small engineering teams using AI coding CLIs inside WSL, Linux shells, containers, or managed corporate laptops.
- · Most likely monetization: SaaS subscription.

MVP Scope · 1–2 weeks
- Build a local CLI that checks OS, WSL, proxy vars, clock sync, DNS reachability, and writable auth paths
- Create a rules engine for classifying auth failures into polling, proxy, version, and network buckets
- Add redacted log collection with explicit user approval
- Design a minimal web dashboard that renders diagnosis and next steps
- Write support docs for common WSL and corporate-network failure patterns
- Add provider-specific checks for device-code polling and token file creation
- Implement known-good version suggestions and rollback guidance
- Ship a shareable diagnostics bundle for maintainers or internal IT teams
- Instrument anonymous telemetry on failure categories to improve rule accuracy
- Launch landing page targeting developer auth troubleshooting keywords
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The pain may be severe but episodic, so many users might prefer free issue-thread troubleshooting over a paid product.
- 2Platform vendors could improve error messages and eliminate enough auth bugs to reduce recurring demand.
- 3Security-conscious teams may block any third-party tool that inspects login environment details, even if data is redacted.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion shows repeated failed logins after browser authorization, multiple attempts across versions, and uncertainty about whether the root cause is polling logic, proxy behavior, or network transport. Several participants mention WSL, company-managed machines, and manual testing of versions and scripts. The pattern indicates a persistent, costly troubleshooting problem rather than a one-off typo.
