mabl Named a Challenger in the 2026 Gartner® Magic Quadrant™ for Agentic Software Quality Assurance Platforms

mabl believes the placement reflects the need for independent verification as coding agents speed up how software gets written.

BOSTON, Oct. 13, 2026 /PRNewswire/ -- mabl, the agentic testing harness, today announced that it has been named a Challenger in the 2026 Gartner® Magic Quadrant™ for Agentic Software Quality Assurance Platforms.¹ This is the first edition of the Magic Quadrant under this name, and mabl's first placement on a Gartner Magic Quadrant, following an Honorable Mention in the 2025 Gartner Magic Quadrant for AI-Augmented Software Testing Tools.²

mabl believes the placement reflects its focus on innovation and providing engineering teams an independent verdict on whether software is ready to ship.

According to Gartner, "AI coding agents are generating software faster than teams can validate it. Traditional approaches to testing cannot keep pace, increasing the risk of defects and creating security vulnerabilities."¹

"Speed was never the hard part. Confidence is," said Dan Belcher, co-founder of mabl. "The agent that writes the code can't be the one that signs off on it. We believe being named a Challenger reflects what our customers count on mabl for: an independent check that keeps pace with their coding agents, and a verdict and paper trail they can stand behind before they ship."

mabl has kept up its pace of innovation since the evaluation period closed, releasing significant advancements such as:

• Verification from inside the coding agent: Developers can create, edit, and run mabl tests directly from their AI coding agent, and create tests locally and in parallel from the terminal.
• Resilient tests that maintain your business requirements: mabl's agent harness keeps business requirements intact, even as tests heal. New test recovery measures mean builders spend less time repairing tests.
• Deeper failure insights in plain language: Builders know why a test failed without digging through logs, and failures are categorized at scale to highlight trends.
• Enterprise governance: Faster and more resilient private connections, alongside company-level quality insights, provide visibility and control for enterprises.

The next evolution of mabl's vision will be unveiled at the company's annual agentic testing conference, Experience 2026, in Boston. Attendees are invited to reimagine how to verify software in the Agentic Development Lifecycle.

About mabl

mabl is the agentic testing harness for modern development that delivers a verdict you can stand behind. Because the agent that writes the code can't be trusted to check it, mabl verifies it independently — authoring, running, and maintaining your tests as one system from the first commit to production. Trusted by industry leaders including Mercedes-Benz, LendingClub Bank, and JetBlue, mabl lets engineering teams move at the speed of AI-driven development without shipping code no one has independently checked.
