Zencoder just launched an AI that can replace days of QA work in two hours

Zencoder, the artificial intelligence coding startup founded by serial entrepreneur Andrew Filev, announced today the public beta launch of Zentester, an AI-powered agent designed to automate end-to-end software testing. This critical but often sluggish step can delay product releases by days or weeks.

The new tool represents Zencoder’s latest attempt to distinguish itself in the increasingly crowded AI coding assistant market, where companies are racing to automate not just code generation but entire software development workflows. Unlike existing AI coding tools that focus primarily on writing code, Zentester targets the verification phase — ensuring software works as intended before it reaches customers.

“Verification is the missing link in scaling AI-driven development from experimentation to production,” said Filev in an exclusive interview with VentureBeat. The CEO, who previously founded project management company Wrike and sold it to Citrix for $2.25 billion in 2021, added: “Zentester doesn’t just generate tests—it gives developers the confidence to ship by validating that their AI-generated or human-written code does what it’s supposed to do.”

The announcement comes as the AI coding market undergoes rapid consolidation. Last month, Zencoder acquired Machinet, another AI coding assistant with over 100,000 downloads. At the same time, OpenAI reached an agreement to acquire coding tool Windsurf for approximately $3 billion (the deal was completed in May). The moves underscore how companies are rushing to build comprehensive AI development platforms rather than point solutions.

Why software testing has become the biggest roadblock in AI-powered development

Zentester addresses a persistent challenge in software development: the lengthy feedback loops between developers and quality assurance teams. In typical enterprise environments, developers write code and send it to QA teams for testing, often waiting several days for feedback. By then, developers have moved on to other projects, creating costly context switching when issues are discovered.

“In a typical engineering process, after a developer builds a feature and sends it to QA, they receive feedback several days later,” Filev told VentureBeat. “By then, they’ve already moved on to something else. This context switching and back-and-forth—especially painful during release crunches—can stretch simple fixes into week-long ordeals.”

Early customer Club Solutions Group reported dramatic improvements, with CEO Mike Cervino stating, “What took our QA team a couple of days now takes developers 2 hours.”

The timing is particularly relevant as AI coding tools generate increasingly large volumes of code. While tools like GitHub Copilot and Cursor have accelerated code generation, they have also created new quality assurance challenges. Filev estimates that if AI tools increase code generation by 10x, testing requirements will similarly increase by 10x — overwhelming traditional QA processes.

How Zentester’s AI agents click buttons and fill forms like human testers

Unlike traditional testing frameworks that require developers to write complex scripts, Zentester operates on plain English instructions. The AI agent can interact with applications like a human user—clicking buttons, filling forms, and navigating through software workflows—while validating both frontend user interfaces and backend functionality.

The system integrates with existing testing frameworks, including Playwright and Selenium, rather than replacing them entirely. “We absolutely do not like people abandoning stuff that’s part of our DNA,” Filev said. “We feel that AI should leverage the processes and tools that already exist in industry.”

Zentester offers five core capabilities: developer-led quality testing during feature development, QA acceleration for comprehensive test suite creation, quality improvement for AI-generated code, automated test maintenance, and autonomous verification in continuous integration pipelines.

The tool represents the latest addition to Zencoder’s broader multi-agent platform, which includes coding agents for generating software and unit testing agents for basic verification. The company’s “Repo Grokking” technology analyzes entire code repositories to provide context, while an error-correction pipeline aims to reduce AI-generated bugs.

The launch intensifies competition in the AI development tools market, where established players like Microsoft’s GitHub Copilot and newer entrants like Cursor are vying for developer mindshare. Zencoder’s approach of building specialized agents for different development phases contrasts with competitors focused primarily on code generation.

“At this point, there are three strong coordination products in the market that are production grade: it’s us, Cursor, and Windsurf,” Filev said in a recent interview. “For smaller companies, it’s becoming harder and harder to compete.”

The company claims superior performance on industry benchmarks, reporting 63% success rates on SWE-Bench Verified tests and approximately 30% on the newer SWE-Bench Multimodal benchmark — results Filev says double previous best performances.

Industry analysts note that end-to-end testing automation represents a logical next step for AI coding tools, but successful implementation requires a sophisticated understanding of application logic and user workflows.

What enterprise buyers need to know before adopting AI testing platforms

Zencoder’s approach offers both opportunities and challenges for enterprise customers evaluating AI testing tools. The company’s SOC 2 Type II, ISO 27001 and ISO 42001 certifications address security and compliance concerns critical for large organizations.

However, Filev acknowledges that enterprise caution is warranted. “For enterprises, we don’t advocate changing software development lifecycles completely, yet,” he said. “What we advocate is AI-augmented, where now they can have quick AI code review and acceptance testing that reduces the amount of work that needs to be done by the next party in the pipeline.”

The company’s integration strategy — working within existing development environments like Visual Studio Code and JetBrains IDEs rather than requiring platform switches — may appeal to enterprises with established toolchains.

The race to automate software development from idea to deployment

Zentester’s launch positions Zencoder to compete for a larger share of the software development workflow as AI tools expand beyond simple code generation. The company’s vision extends to full automation from requirements to production deployment, though Filev acknowledges current limitations.

“The next jump is going to be requirements to production — the whole thing,” Filev said. “Can you now pipe it so that you could have natural language requirements and then AI could help you break it down, build architecture, build code, build review, verify that, and ship it to production?”

Zencoder offers Zentester through three pricing tiers: a free basic version, a $19 per user per month business plan, and a $39 per user per month enterprise option with premium support and compliance features.

For an industry still debating whether artificial intelligence will replace programmers or simply make them more productive, Zentester suggests a third possibility: AI that handles the tedious verification work while developers focus on innovation. The question is no longer whether machines can write code—it’s whether they can be trusted to test it.
