Holstr is an all-in-one desktop testing and quality workflow app for planning, capturing, analysing, and validating product behavior in one place. It combines structured exploratory testing (Chartr), execution tracking (Trackr), guided learning (Learnr), interaction capture (Captr), accessibility and performance analysis (Cybr), visual system mapping (Mapr), and API/service testing (Injectr) so teams can move from test design to evidence and reporting faster.

• Captr — Records real user interactions with event-linked screenshots to create clear, step-by-step evidence of what happened making defects easily identified and quickly fixed.

• Cybr — Runs fast accessibility scans on live sites or offline packages to surface risks and produce actionable findings that can be easily fed into AI powered IDE to easily fix each issue quickly and reliably making your site pass googles algo checks, which helps get to the top of the natural search listings saving money on marketing and creating a better user experience for your customers.

• Mapr — Builds visual mind maps of systems, risks, and test paths to improve analysis, planning, and communication.

• Injectr — Tests APIs with REST and SOAP support, including headers, auth, WSDL-assisted operations, and readable response output.

• Chartr — Defines focused exploratory testing charters with mission, scope, focus areas, resources, and expected outcomes.

• Trackr — Organizes testing sessions in a simple workflow (To Do, In Progress, Done) so teams can plan, prioritize, and deliver.

• Learnr — Provides practical testing guidance and structured quality pointers to help teams improve test depth and consistency.
