Virtuoso QA is a secure, agentic test automation platform for any browser-based application. Touchstone, our agentic assurance layer, turns your business requirements into tests, then runs, fixes and maintains them as your application changes. More than thirty specialised agents author, generate, triage and self-heal your functional and end-to-end tests, while a deterministic engine executes every run and your team approves every decision that matters. Every release comes with evidence of what was tested, what changed and who approved it. Release Insights shows execution risk and requirement coverage across every journey, and teams can export an Evidence Report in minutes rather than assembling one over weeks. That makes the platform a natural fit for regulated industries like financial services, insurance, healthcare, the public sector and more. The mission is to set the standard of proof for software releases. AI generates software. Virtuoso QA generates the evidence to trust it.

Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap. Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery. The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team. Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required. The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.

You know that you could be testing more to catch bugs earlier, but QA testing can take a lot of time, effort and resources to do it right. MuukTest can get growing engineering teams up to 95% coverage of end-to-end tests in just 3 months. Our QA experts create, manage, maintain, and update E2E tests on the MuukTest Platform for your web, API, and mobile apps at record speed. We begin exploratory and negative tests after achieving 100% regression coverage within 8 weeks to uncover bugs and increase coverage. The time you spend on development is reduced by managing your testing frameworks, scripts, libraries and maintenance. We also proactively identify flaky tests and false test results to ensure the accuracy of your tests. Early and frequent testing allows you to detect errors in the early stages your development lifecycle. This reduces the burden of technical debt later on.

Flagsmith gives software engineering teams a self-hosted or fully managed feature flagging platform for controlling releases across web, mobile, and backend systems. Ship code behind a flag, then decide who sees it — by environment, user, or custom segment — without redeploying. Run Flagsmith however fits your infrastructure: our managed cloud, your own private cloud, or fully on-premise. What you get: Progressive rollouts with one-click rollback if something breaks Live config changes — flip features on or off instantly, no redeploy required Segment-based A/B and multivariate testing Project and role-based access control for multi-team organizations Native integrations with the tools already in your stack MCP support and a CLI so AI agents and scripts can manage flags directly Open source at its core, Flagsmith is built for teams that want control over where their configuration data lives.

Pensero is a cutting-edge platform that leverages AI to enhance observability and performance analytics, designed specifically for engineering teams and their leaders to gain a deeper understanding of software development processes. It automates the collection and integration of "work signals" from existing tools utilized by your team, including code repositories, issue trackers, and communication platforms, translating disjointed activities into granular insights. These insights are then converted into objective metrics, live dashboards, and comprehensive reports that not only reflect the volume of work completed but also factor in complexity and workflow dynamics. With Pensero, you gain immediate visibility into ongoing projects, contributions from team members, and the overall flow of work within the organization, as well as how team productivity aligns with strategic roadmaps and business objectives. Its seamless integration and scalability enable teams to swiftly transform raw data from various tools into actionable insights that drive performance improvements. Ultimately, Pensero empowers organizations to optimize their software development efforts more effectively than ever before.

Reflectiz is a web exposure management platform that enables organizations to proactively identify, monitor, and mitigate security, privacy, and compliance risks across their digital environments. It provides comprehensive visibility and control over first, third, and even fourth-party components like scripts, trackers, and open-source libraries—elements that are often missed by traditional security tools. The unique advantage of Reflectiz is that it operates remotely, without embedding code on customer websites.
