Reverse Proxy Configuration Linter & CI/CD Plugin
A developer tool that statically analyzes API configurations and reverse proxy setups to detect insecure TLS terminations and header forwarding issues before they reach production.
Why this matters
You spend days perfectly crafting a robust backend API, writing tests, and ensuring all endpoints work flawlessly locally. But the moment you deploy it behind a cloud load balancer or reverse proxy, your routing logic falls apart. Suddenly, secure requests are being downgraded to unencrypted links, and missing trailing slashes cause infinite redirect loops. Instead of building features, you find yourself deep in documentation, trying to figure out which obscure forwarded-header setting is failing. Existing security scanners miss this completely because the issue lies perfectly in the gap between your infrastructure configuration and your framework's internal routing logic.
- · Built for DevOps engineers and backend developers managing their own cloud infrastructure or containerized deployments..
- · Most likely monetization: Freemium SaaS (Free for public repos, paid for private CI/CD integration).

Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1The target audience might prefer to use fully managed deployment platforms (like Render or Vercel) that abstract these networking issues entirely.
- 2The problem is highly technical and specific, making it difficult to market as a standalone product rather than a feature of a larger security suite.
- 3Framework maintainers may eventually release native patches that handle proxy header mismatches gracefully out of the box.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
Several developers reported significant frustration when application frameworks improperly handled secure protocol headers passed by infrastructure proxies. They detailed relying on risky workarounds—like explicitly trusting all incoming forwarded headers or writing custom routing interceptors—just to prevent secure endpoints from downgrading to plain HTTP during redirects. The discussion highlighted a clear gap in tools capable of validating these integration points automatically.
