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. 131 Ratings Visit Website Checksum.ai Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability. Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort. Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in. Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens. The result: ship faster, with confidence. 2 Ratings Visit Website InboxAlly InboxAlly is an email deliverability platform for senders whose messages are landing in spam or promotions instead of the primary inbox. It repairs and protects sender reputation at the domain and IP level, warms up new domains and IPs on an adaptive schedule, and shows where messages actually land through inbox placement testing across Gmail, Outlook, Yahoo and other major mailbox providers. Live blacklist monitoring and deliverability alerts surface problems as they develop rather than after a campaign underperforms, and an ML-modeled sender score makes reputation measurable week to week. InboxAlly runs alongside the stack you already have. It works with any ESP, SMTP service or custom sending infrastructure - including Mailchimp, SendGrid, Amazon SES, Brevo, Klaviyo, HubSpot and Instantly - with no migration and no change to how you send, and without handing over your sending credentials. A REST API and native integrations support programmatic setup, and separate sender profiles let agencies and multi-brand senders manage many domains side by side. Based in New York, InboxAlly supports email marketers, agencies, cold outreach teams, SaaS senders and deliverability consultants, from a single domain to enterprise sending programs. Every plan includes a dedicated customer success manager and 24/7 live support, and evaluation starts with a 10-day free trial that requires no credit card. 136 Ratings Visit Website Gearset Gearset is the complete, enterprise-ready Salesforce DevOps platform, enabling teams to implement best practices across the entire DevOps lifecycle.

Unlike traditional vulnerability tools that focus on application layers, z/Assure VAP conducts thorough and precise binary code scanning at the OS level to detect zero-day and integrity-based vulnerabilities without relying on signature files, using an Interactive Application Security Testing (IAST)-style approach to pinpoint real weaknesses and guide developers to the exact code requiring remediation. It generates detailed vulnerability disclosure reports that provide actionable insights and clear paths to fix issues, enabling teams to prioritize risk, strengthen defenses, and make mainframe vulnerability management a repeatable part of IT security and compliance programs. 1 Rating Visit Website Flagsmith Flagsmith is a fully supported open-source feature flag, remote config, and A/B testing service.

	Pros & Cons from Real Users Pros What I liked most about Testsigma is its intuitive Drag & Drop interface, which simplifies test creation and makes it accessible for both technical and non-technical users. The powerful mobile app and REST API testing features are also standout aspects. 1. Possibility to create autotests without programming knowledge 2. It takes not a lot of time to learn how to set up your project 3. Quick response of support team to any concerns 4. Constant development of product 5. Wide variety of settings to create, execute test cases 6. Presence of API testing 7. Cross browser, cross platform testing 1) With the minimum training users can handle the application. That is a unique feature in Testsigma. 2) Test step grouping is one more unique feature that helps to reduce the time to develop new scripts. - Easy to learn and use - Allows use of custom functions - Ability to reuse elements and steps - Bundling of test cases and test plans - Scheduling runs - Automatic rerun of failed cases - API testing - JIRA Integration Can be sued with simple English Multiple OS and browser versions Very simple, even someone non-technical person can perform automation Cons While Testsigma is generally very efficient and user-friendly, there are occasional moments when the platform can feel a bit slow during peak usage times. However, these instances are rare and do not significantly impact overall productivity. 1. Sometimes presence of bugs, instability in product which can cause some inconvenience Most of the features are good, with no cons at the moment. Need to improve on: - Better communication on changes - removal of certain symbols from UI identifier names, changing test plan run settings, deprecating certain test steps, etc. cause more maintenance and upkeep. - Need detailed release notes So far it is working great.I have no issues with it
