Zencoder drops Zenflow, a free AI orchestration tool that pits Claude against OpenAI’s models to catch coding errors

Zencoder, the Silicon Valley startup that builds AI-powered coding agents, released a free desktop application on Monday that it says will fundamentally change how software engineers interact with artificial intelligence — moving the industry beyond the freewheeling era of “vibe coding” toward a more disciplined, verifiable approach to AI-assisted development.

The product, called Zenflow, introduces what the company describes as an “AI orchestration layer” that coordinates multiple AI agents to plan, implement, test, and review code in structured workflows. The launch is Zencoder’s most ambitious attempt yet to differentiate itself in an increasingly crowded market dominated by tools like Cursor, GitHub Copilot, and coding agents built directly by AI giants Anthropic, OpenAI, and Google.

“Chat UIs were fine for copilots, but they break down when you try to scale,” said Andrew Filev, Zencoder’s chief executive, in an exclusive interview with VentureBeat. “Teams are hitting a wall where speed without structure creates technical debt. Zenflow replaces ‘Prompt Roulette’ with an engineering assembly line where agents plan, implement, and, crucially, verify each other’s work.”

The announcement arrives at a critical moment for enterprise software development. Companies across industries have poured billions of dollars into AI coding tools over the past two years, hoping to dramatically accelerate their engineering output. Yet the promised productivity revolution has largely failed to materialize at scale.

Why AI coding tools have failed to deliver on their 10x productivity promise

Filev, who previously founded and sold the project management company Wrike to Citrix, pointed to a growing disconnect between AI coding hype and reality. While vendors have promised tenfold productivity gains, rigorous studies — including research from Stanford University — consistently show improvements closer to 20 percent.

“If you talk to real engineering leaders, I don’t remember a single conversation where somebody vibe coded themselves to 2x or 5x or 10x productivity on serious engineering production,” Filev said. “The typical number you would hear would be about 20 percent.”

The problem, according to Filev, lies not with the AI models themselves but with how developers interact with them. The standard approach of typing requests into a chat interface and hoping for usable code works well for simple tasks but falls apart on complex enterprise projects.

Zencoder’s internal engineering team claims to have cracked a different approach. Filev said the company now operates at roughly twice the velocity it achieved 12 months ago, not primarily because AI models improved, but because the team restructured its development processes.

“We had to change our process and use a variety of different best practices,” he said.

Inside the four pillars that power Zencoder’s AI orchestration platform

Zenflow organizes its approach around four core capabilities that Zencoder argues any serious AI orchestration platform must support.

Structured workflows replace ad-hoc prompting with repeatable sequences (plan, implement, test, review) that agents follow consistently. Filev drew parallels to his experience building Wrike, noting that individual to-do lists rarely scale across organizations, while defined workflows create predictable outcomes.

Spec-driven development requires AI agents to first generate a technical specification, then create a step-by-step plan, and only then write code. The approach became so effective that frontier AI labs including Anthropic and OpenAI have since trained their models to follow it automatically. The specification anchors agents to clear requirements, preventing what Zencoder calls “iteration drift,” or the tendency for AI-generated code to gradually diverge from the original intent.

Multi-agent verification deploys different AI models to critique each other’s work. Because AI models from the same family tend to share blind spots, Zencoder routes verification tasks across model providers, asking Claude to review code written by OpenAI’s models, or vice versa.

“Think of it as a second opinion from a doctor,” Filev told VentureBeat. “With the right pipeline, we see results on par with what you’d expect from Claude 5 or GPT-6. You’re getting the benefit of a next-generation model today.”

Parallel execution lets developers run multiple AI agents simultaneously in isolated sandboxes, preventing them from interfering with each other’s work. The interface provides a command center for monitoring this fleet, a significant departure from the current practice of managing multiple terminal windows.

How verification solves AI coding’s biggest reliability problem

Zencoder’s emphasis on verification addresses one of the most persistent criticisms of AI-generated code: its tendency to produce “slop,” or code that appears correct but fails in production or degrades over successive iterations.

The company’s internal research found that developers who skip verification often fall into what Filev called a “death loop.” An AI agent completes a task successfully, but the developer, reluctant to review unfamiliar code, moves on without understanding what was written. When subsequent tasks fail, the developer lacks the context to fix problems manually and instead keeps prompting the AI for solutions.

“They literally spend more than a day in that death loop,” Filev said. “That’s why the productivity is not 2x, because they were running at 3x first, and then they wasted the whole day.”

The multi-agent verification approach also gives Zencoder an unusual competitive advantage over the frontier AI labs themselves. While Anthropic, OpenAI, and Google each optimize their own models, Zencoder can mix and match across providers to reduce bias.

“This is a rare situation where we have an edge on the frontier labs,” Filev said. “Most of the time they have an edge on us, but this is a rare case.”

Zencoder faces steep competition from AI giants and well-funded startups

Zencoder enters the AI orchestration market at a moment of intense competition. The company has positioned itself as a model-agnostic platform, supporting major providers including Anthropic, OpenAI, and Google Gemini. In September, Zencoder expanded its platform to let developers use command-line coding agents from any provider within its interface.

That strategy reflects a pragmatic acknowledgment that developers increasingly maintain relationships with multiple AI providers rather than committing exclusively to one. Zencoder’s universal platform approach lets it serve as the orchestration layer regardless of which underlying models a company prefers.

The company also emphasizes enterprise readiness, touting SOC 2 Type II, ISO 27001, and ISO 42001 certifications along with GDPR compliance. These credentials matter for regulated industries like financial services and healthcare, where compliance requirements can block adoption of consumer-oriented AI tools.

But Zencoder faces formidable competition from multiple directions. Cursor and Windsurf have built dedicated AI-first code editors with devoted user bases. GitHub Copilot benefits from Microsoft’s distribution muscle and deep integration with the world’s largest code repository. And the frontier AI labs continue expanding their own coding capabilities.

Filev dismissed concerns about competition from the AI labs, arguing that smaller players like Zencoder can move faster on user experience innovation.

“I’m sure they will come to the same conclusion, and they’re smart and moving fast, so I’m sure they will catch up fairly quickly,” he said. “That’s why I said in the next six to 12 months, you’re going to see a lot of this propagating through the whole space.”

The case for adopting AI orchestration now instead of waiting for better models

Technical executives weighing AI coding investments face a difficult timing question: Should they adopt orchestration tools now, or wait for frontier AI labs to build these capabilities natively into their models?

Filev argued that waiting carries significant competitive risk.

“Right now, everybody is under pressure to deliver more in less time, and everybody expects engineering leaders to deliver results from AI,” he said. “As a founder and CEO, I do not expect 20 percent from my VP of engineering. I expect 2x.”

He also questioned whether the major AI labs will prioritize orchestration capabilities when their core business remains model development.

“In the ideal world, frontier labs should be building the best-ever models and competing with each other, and Zencoders and Cursors need to build the best-ever UI and UX application layer on top of those models,” Filev said. “I don’t see a world where OpenAI will offer you our code verifier, or vice versa.”

Zenflow launches as a free desktop application, with updated plugins available for Visual Studio Code and JetBrains integrated development environments. The product supports what Zencoder calls “dynamic workflows,” meaning the system automatically adjusts process complexity based on whether a human is actively monitoring and on the difficulty of the task at hand.

Zencoder said internal testing showed that replacing standard prompting with Zenflow’s orchestration layer improved code correctness by approximately 20 percent on average.

What Zencoder’s bet on orchestration reveals about the future of AI coding

Zencoder frames Zenflow as the first product in what it expects to become a significant new software category. The company believes every vendor focused on AI coding will eventually arrive at similar conclusions about the need for orchestration tools.

“I think the next six to 12 months will be all about orchestration,” Filev predicted. “A lot of organizations will finally reach that 2x. Not 10x yet, but at least the 2x they were promised a year ago.”

Rather than competing head-to-head with frontier AI labs on model quality, Zencoder is betting that the application layer (the software that helps developers actually use these models effectively) will determine winners and losers.

It is, Filev suggested, a familiar pattern from technology history.

“This is very similar to what I observed when I started Wrike,” he said. “As work went digital, people relied on email and spreadsheets to manage everything, and neither could keep up.”

The same dynamic, he argued, now applies to AI coding. Chat interfaces were designed for conversation, not for orchestrating complex engineering workflows. Whether Zencoder can establish itself as the essential layer between developers and AI models before the giants build their own solutions remains an open question.

But Filev seems comfortable with the race. The last time he spotted a gap between how people worked and the tools they had to work with, he built a company worth over a billion dollars.
