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.

QA Wolf is the fastest path to deterministic
end-to-end test coverage for web and mobile apps. In one platform, teams can manage the entire testing lifecycle: Map out your workflows and coverage gaps, automate your tests in Playwright or Appium, and run your suite fully in parallel. - Build and maintain E2E tests 10x faster than agentic CLIs. - Run tests 12x faster than non-deterministic computer-use agents. - Release 5x more often with faster testing. Want all your testing done for you? QA Wolf’s Coverage as a Service delivers 80%+ test coverage in 4 months with 24-hour failure investigation, test maintenance, and guaranteed zero flakes.

Are bugs slipping through your QA process and frustrating your customers? Catching issues early shouldn’t mean overwhelming your team with time-consuming tests. With MuukTest’s AI-driven platform, growing engineering teams reach 95% end-to-end test coverage in just 3 months, delivering quality at speed. By leveraging AI, our QA experts rapidly design, manage, and maintain comprehensive E2E tests for web, mobile, and API applications on the MuukTest platform. Within 8 weeks, we deliver full regression coverage, followed by exploratory and negative testing to uncover hidden bugs and expand test scenarios. We also proactively identify and address flaky tests and false results to ensure the reliability of your tests. Testing early and often allows you to detect bugs in the early stages of your development lifecycle, reducing the burden of technical debt down the line.

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.

Flagsmith is a fully supported open-source feature flag, remote config, and A/B testing service. Use our hosted API, deploy to your own private cloud, or run on-premise. Create and manage feature flags across web, mobile, and server-side applications. Wrap a section of code with a flag, and then use Flagsmith to toggle that feature on or off for different environments, users, or user segments. Feature flags – Release features with phased rollouts and instant rollback capabilities. Remote config – Toggle individual features on and off, and make changes without deploying new code. A/B and multivariate testing – Use segments to run A/B and multivariate tests on new features. Introduce beta programs to get early user feedback. Organization management – Projects, and roles for team members help keep your deployment organized. Integrations – Connect to your favorite tools. MCP and CLI – Set up automated feature management workflows controlled by your AI agents

Secure your code, cloud, and runtime in one central system. Aikido’s all-in-one security platform is loved by developers and security teams alike with full security visibility, insight in what matters most, and fast/automatic vulnerability fixes. Teams get security done with Aikido thanks to: - False-positive reduction - AI Autotriage & AI Autofix - Deep integration into the dev workflow (from IDEs and task managers to CI/CD gating) - AI Pentests - Automated Compliance Aikido covers the entire Software Development Lifecycle (SDLC), including: static application security testing (SAST), dynamic application security testing (DAST), infrastructure-as-code (IaC), container scanning, secrets detection, open source license scanning (SCA), cloud posture management (CSPM), runtime protection, AI pentests, and more.

Astra’s Pentest is a comprehensive penetration testing solution with an intelligent automated vulnerability scanner coupled with in-depth manual pentesting. On top of 10000+ tests including security checks for all CVEs mentioned in the OWASP top 10, and SANS 25, the automated scanner also conducts all tests required to comply with ISO 27001, HIPAA, SOC2, and GDPR. Astra offers an interactive pentest dashboard that the user can use to visualize vulnerability analyses, assign vulnerabilities to team members, and collaborate with security experts. And if the users don’t want to get back to the dashboard every time they want to use the scanner or assign a vulnerability to a team member, they can simply use the integrations with CI/CD platforms, Slack, and Jira.

Okyline is an Executable Data Design (EDD) platform for declarative data validation contracts and measurable operational data quality. Instead of maintaining disconnected specifications, validators, tests, and quality dashboards, Okyline uses a single executable contract as the operational source of truth for validation and flow quality monitoring. The same readable contract drives multi-format validation, deterministic execution, quality measurement, data quality gate, and historical quality analytics across APIs, events, files, LLM structured outputs, and enterprise data flows. Community Edition provides the open specification, a free Java validation runtime, a public Claude AI assistant for contract generation, and a free online studio for executable JSON validation contracts and JSON Schema transpilation. Enterprise Edition supports direct validation of JSONL, XML, CSV, FIXED, and EDI flows, data quality gate, and operational quality dashboards, all without databases
