Evidence to inspect

Use “Best code security tools for startups” as the scope for this decision: verify the input, finding detail, workflow handoff, and product boundary before you install or buy.

CriterionEvidence to inspectBoundary

Input scopeSelected files, configuration, scan mode, and enabled rules.Only included paths and configured checks are evaluated.

Finding detailFile, line, rule ID, severity, explanation, and repair direction.Illustrative output is not a result from your repository.

Workflow handoffLocal result, report format, agent context, and optional CI signal.Enable exports or CI only when the workflow needs them.

Decision fitUse the same criteria on a real repository before choosing a plan or tool.No universal winner or guaranteed outcome is claimed.
