# Overview

The **Overview** page is the landing screen for a project in Qlty Cloud. It surfaces the health of the project's default branch across three lenses: **Maintainability**, **Coverage**, and **Security**.

## Headline metrics

The Overview reports an A–F grade for each lens, computed from the tracked branch:

* **Maintainability** — overall code quality grade based on smells, complexity, and duplication.
* **Coverage** — line coverage percentage and grade.
* **Security** — count and severity of open security findings.

Three tabs scope the rest of the page to a single lens.

## Hotspots

The Hotspots list shows the top files in the project that most need attention for the selected lens:

* **Maintainability** — top files by remediation effort (highest [Effort](/cloud/maintainability/metrics#effort) first).
* **Coverage** — top files by lowest line coverage, excluding files with no coverage data.
* **Security** — top files by open security finding count.

Each entry links into the file's metrics page for a deeper view. See [Coverage Hotspots](/coverage/hotspots) for the coverage-specific behavior.

## Trend chart

A 30-day time-series chart shows how the selected lens has evolved on the tracked branch, with one data point per day. The lens determines what's plotted — technical debt, coverage percent, or security issue count. See [Coverage Trends](/coverage/trends) for the coverage-specific chart.

## Sunburst chart

A radial visualisation of the project's directory tree, colour-coded by either complexity or coverage. Each ring is a directory level; segment size is proportional to lines of code. Useful for spotting concentrations of risk at a glance.

## Files by grade

A breakdown of how many files in the project sit at each maintainability rating (A through F).

* **[Issues](/cloud/projects/issues)** — Browse and filter every open finding.
* **[Pull Requests](/cloud/projects/pull-requests)** — Review per-PR analysis and coverage.
