JWT-to-RLS Debugger for Backend Teams
Build a developer tool that traces a single authenticated request from token issuance through verification, role extraction, and row-level security context. The value is faster root-cause analysis when auth appears valid but data-layer authorization fails, especially around key rotation and algorithm changes.
これが重要な理由
You ship an app with JWT auth and row-level security, then a routine security change causes a confusing outage. Login still works, user identity checks look healthy, but real API requests hit the database as if nobody is signed in. You bounce between auth responses, API logs, SQL role tests, and support threads, yet none of those prove what happened on the live request path. The biggest frustration is not just the failure itself, but the wasted hours spent proving whether the token was missing, mistrusted, or mapped to the wrong role. A focused debugger that shows the exact break point would remove a painful class of production incidents.
- · Small engineering teams and solo developers running production apps on managed Postgres backends with JWT-based auth and row-level security.向けに構築。

- Add connectors for managed backend config inputs such as project URL, anon key, and JWKS endpoint
- Implement a diagnostic decision tree for stale keys, missing bearer headers, and role-claim issues
- Add secure redaction for tokens, claims, and logs before storage
- Create a shareable incident report summarizing findings for engineering teams
- Run outreach to developers discussing JWT and RLS debugging issues to recruit first users

自己反論 — 最も重要な信頼のシグナル
- 1Platform-native logs and docs may improve enough that developers prefer free built-in debugging paths.
- 2Without deep integration into backend internals, the product may diagnose symptoms but not confidently prove root cause in all cases.
- 3Security-sensitive buyers may avoid a third-party debugging service unless self-hosting or strict redaction is available.
エビデンスの概要
AIがこのインサイトをどのように統合したか — 逐語的な引用はありません
The discussion repeatedly points to a mismatch between successful identity validation and failed row-level security behavior. Multiple participants focus on whether the live request is actually carrying a trusted JWT and correct role context, and they recommend manual debugging across SQL, gateway logs, and token claims. That combination suggests a real and recurring need for software that unifies these checks into a single diagnosis flow.
