What Holstr is

Holstr is a desktop exploratory testing powerhouse for test planning, test execution and reporting exploratory testing sessions. It combines test capture (Captr), test charters (Chartr), test session management (trackr), learning (Learnr), accessibility and performance scanning (Cybr), mind mapping (Mapr), and API/SOAP testing (Injectr) all in one app.

Core workflow

• 1. Plan in Chartr (Learnr provides guidance if needed).
• 2. Execute and collect exploratory test evidence (which can be annotated post recording) in Captr.
• 3. Track progress in Trackr and organise test sessions.
• 4. Analyse performance and accessibility in Cybr (the output can be easily uploaded into an AI Agent workflow/IDE in a format AI can easily understand to execute the recommended fixes to make your app more accessible and performant).
• 5. Model systems and risks in Mapr.
• 6. Validate APIs in Injectr.
• 7. Export reports for sharing.

Feature guide

Captr

• Captures screenshot-backed user-event evidence during sessions.
• Supports three recording surfaces:
• Web Apps
• Browsers
• Desktop Apps
• Links events to screen captures for easily reproducible visual defect evidence.

Chartr

• Creates structured exploratory test charters.
• Each test charter includes:
• Mission
• Scope
• Focus areas
• Resources
• Expected outcome
• Includes professional, scenario-based starter content.

Trackr

• Tracks session work in Kanban lanes:
• To Do
• In Progress
• Done
• Create/edit test sessions, you can arrange and/or colour the test session tiles to set priority, move test session tiles across lanes, and attach export links.

Learnr

• Provides practical testing pointers by category.
• Helps teams improve coverage, risk thinking, and test quality decisions.

Cybr

• Runs web-focused analysis in:
• Online mode (live URL)
• Offline mode (packaged site/content)
• Surfaces quality/performance/accessibility-related findings for review and export.

Mapr

• Mind-mapping workspace for test targets, architecture, and risk paths.
• Supports node/link visualisation and map sessions for planning discussions.
• The mind maps can be exported to print/pdf.

Injectr

• API/service validation tool for:
• Multiple REST requests (method, headers, auth, body)
• Multiple SOAP requests (endpoint, action, XML)
• WSDL loading for service/operation discovery
• Shows raw and formatted responses for investigation.

Export

• Exports test outputs as clear reports (including combined pdf exports).
• Can include session Captr, Chartr, and Cybr output.
• Supports linking exports back to Trackr sessions.

Who it is for

• Crowd testers
• Exploratory testers
• QA engineers
• User acceptance testers
• Security-minded test teams
• Business owners (transparency of web sites a 3rd party could be building for them using Cybr scans automated output, or for assessing an existing site that may need upgraded)
• Design teams
• Training teams (output from Captr works great for creating walkthroughs of apps and systems, it's also great for "new joiner"/"how to" content)
• Product teams that need evidence-rich reporting and reproducible findings
• Heavily regulated industries (e.g. Finance, Energy & Healthcare) that would benefit from being highly auditable by capturing every click and value tested quickly and easily in pdf format
