Virtuoso QA
Virtuoso QA
Virtuoso QA is an enterprise agentic test automation platform setting the standard of proof for software releases. As AI accelerates how software is built, Virtuoso QA helps organisations release with confidence through governed, agentic automation for functional, regression and end-to-end testing across any browser-based application, from Dynamics 365, Salesforce and SAP to Guidewire and custom-built systems. Virtuoso QA turns requirements, designs, live applications or existing suites into executable journeys. Through Touchstone, its agentic layer, brings in 30+ specialised agents to do the work, grounded in your sources and standards. The Analyst turns documentation into source-cited test requirements, the Architect designs the journeys that prove them, and Autopilot builds each one. Your team reviews and approves each stage, so nothing enters the suite on trust. Tests run on a deterministic engine within existing CI/CD pipelines, and self-healing fixes are proposed as reviewable diffs, keeping test suites current without manual rework. Every release is backed by evidence of what was tested, what changed and who approved it. That is why organisations in financial services, insurance, healthcare and the public sector trust Virtuoso QA where releases carry consequences. -

Request input requires a public-facing OpenAPI Spec URL, an API authentication token valid for at least 10 mins, an active license key, and an email. EthicalCheck engine automatically creates and runs custom security tests for your APIs covering OWASP API Top 10 list Automatically removes false positives from the results, creates a custom developer-friendly report, and emails it to you. According to Gartner, APIs are the most-frequent attack vector. Hackers/bots have exploited API vulnerabilities resulting in major breaches across thousands of organizations. Only see real vulnerabilities; false positives are automatically separated. Generate enterprise-grade penetration test reports. Confidently share it with developers, customers, partners, and compliance teams. Using EthicalCheck is similar to running a private bug-bounty program.Starting Price: $99 one-time payment -

Spitfire
Albiferro Software & System
Spitfire is a self-hosted load-testing and performance-monitoring platform for DevOps, QA, and SRE teams. It runs on customer infrastructure with Docker or Kubernetes, with remote runners in multiple locations that dial out without inbound ports. Users build tests without scripting in a browser-based editor or import OpenAPI, Postman, HAR, k6, and JMeter files. A test can combine HTTP, gRPC, WebSocket, Kafka, MQTT, SQL, and real browser users. Run tests as low-load production monitors every 1–60 minutes, with drift detection, SLOs, error budgets, and a status page, or as staged distributed load tests to find breaking points and performance bottlenecks. OpenTelemetry data and alerts from Datadog, New Relic, Dynatrace, Zabbix, and Instana help investigate slowdowns. A/B version comparisons can serve as CI release gates. Spitfire also includes a production-write guard, SSO/SCIM, audit logs, and offline licensing for air-gapped installations. A free edition has no expiration.Starting Price: $1,485/year -
