Frontend Quality Copilot
Build a SaaS that unifies real-user performance, JS errors, accessibility findings, and user-friction events into one prioritized quality dashboard. The value is not raw metrics collection alone, but helping teams understand which frontend issues are actually harming user journeys and deserve engineering time.
これが重要な理由
You already have several frontend signals, but none of them tell a complete story. One tool shows page metrics, another shows JavaScript errors, another checks accessibility, and support feedback arrives later after users have already struggled. As a result, you end up debating whether a bad metric matters, or whether a user complaint was caused by speed, broken interactions, or usability issues. You need a single view that connects technical quality to the moments users care about most, such as logging in, searching, or submitting a form. If software could rank the biggest risks by likely user impact, it would help teams justify proactive fixes instead of waiting for frustration to pile up.

10 teams install the SDK and 3 convert to paid plans within 30 days
MVPの範囲 · 1～2週間
- Build a simple browser SDK to capture LCP, INP, CLS, JS errors, and failed form submits
- Create a backend endpoint to receive events and store them in PostgreSQL or ClickHouse
- Design a minimal dashboard with app overview and top broken flows
- Add manual tagging for critical user journeys such as signup or checkout
- Implement a plain-language issue summary that groups metrics by likely user impact
- Add Sentry import so teams can correlate SDK events with existing error reports
- Launch alerts for regressions in critical flows rather than only page-level metrics
- Add rage-click and repeated-submit heuristics as friction indicators
- Create a lightweight onboarding wizard with copy-paste install steps
- Ship a billing page and a 14-day trial for early design partners

失敗する可能性がある理由
自己反論 — 最も重要な信頼のシグナル
- 1Established observability vendors can add similar views quickly, making it hard to stand out unless the workflow is dramatically better.
- 2Teams may claim this matters but still avoid paying if current dashboards feel good enough for their scale.
- 3If prioritization logic produces noisy or obvious recommendations, users will stop checking the product after initial setup.
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
Several commenters described using separate tools for performance, accessibility, and error tracking rather than one coherent system. Multiple responses emphasized that complaint signals and broken flows often reveal issues that page-level dashboards miss. There was repeated demand for real-user data, flow-level timing, and better interpretation of what metrics mean for actual experience, which supports a product that sits above raw telemetry and turns it into decisions.
