Features and specs

What each product offers, as listed by its team.

Zeplin 5 features
Proofrun 8 features
  • Ease of Collaboration
    Zeplin facilitates seamless collaboration between designers and developers by providing a shared space where they can access design specifications, assets, and resources.
  • Design Consistency
    By offering detailed design specifications and exportable assets, Zeplin ensures consistency across different development platforms and helps maintain a unified design system.
  • Automated Asset Export
    Zeplin automatically generates assets in various formats and resolutions, which saves time and reduces the likelihood of errors during the handoff process.
  • Integration with Design Tools
    Zeplin integrates seamlessly with popular design tools like Sketch, Adobe XD, Figma, and Photoshop, making it easy for designers to upload and manage their projects.
  • Version Control
    The platform offers version control for design projects, enabling teams to track changes, revert to previous versions, and ensure they're always working with the most up-to-date designs.

Possible disadvantages

  • Pricing
    Zeplin's subscription model can be costly for smaller teams or individual freelancers, especially when compared to other design handoff tools available in the market.
  • Limited Prototyping Features
    Unlike some other design collaboration tools, Zeplin lacks advanced prototyping features, which might necessitate the use of additional tools for complete design validation.
  • Learning Curve
    New users may require some time to learn Zeplin’s interface and features, which could be a challenge for teams that need to quickly onboard and get up to speed.
  • Dependency on Design Tools
    Zeplin relies heavily on imported designs from other tools rather than allowing for direct design creation within its platform. This dependency could be a limitation for teams looking for an all-in-one solution.
  • Limited Free Tier
    The free version of Zeplin is quite limited in terms of the number of projects and collaborators, which might not be sufficient for larger teams or complex projects.
  • AI-Powered Product Discovery
    Investigate product problems, opportunities, requirements, and hypotheses using AI-assisted research.
  • Competing Hypotheses
    Explore multiple explanations and challenge assumptions instead of simply confirming an initial idea.
  • Evidence Traceability
    Connect evidence to hypotheses, preserving sources, context, and the reasoning behind findings.
  • Contradictions & Research Gaps
    Identify conflicting evidence, unresolved questions, and areas requiring further investigation.
  • Living Discoveries
    Preserve research, hypotheses, evidence, and evolving interpretations in a persistent Discovery.
  • Keep Alive Monitoring
    Reassess Discoveries as relevant new signals emerge and highlight changes that deserve attention
  • Research & Decision Briefs
    Generate structured briefs summarizing findings, supporting evidence, uncertainties, and possible directions.
  • Public Web Research
    Research public information and evaluate sources to support product investigations.

Questions & Answers

As answered by people managing Zeplin and Proofrun.

Why should a person choose your product over its competitors?

Proofrun's answer:

Because product decisions need more than AI-generated answers or another place to store research.

Proofrun is designed for the work between identifying a problem and deciding what to do about it.

Instead of starting from scratch every time a question comes up, you can build on an existing Discovery, examine competing hypotheses, trace evidence back to its sources, and understand what has changed.

It helps product professionals challenge assumptions, make uncertainty visible, and preserve the reasoning behind their work.

For individual PMs and founders, that means a more structured way to investigate real problems.

For product teams, it creates a foundation for shared context, traceability, and continuity.

You don't need another confident AI answer. You need to understand whether the evidence actually supports it.

What makes your product unique?

Proofrun's answer:

Most AI research tools give you an answer. Proofrun helps you understand how that answer was formed, what evidence supports it, what contradicts it, and what could change it.

Proofrun turns product questions, problems, and opportunities into Living Discoveries that connect competing hypotheses, traceable evidence, contradictions, and research gaps.

With Keep Alive, a Discovery can be revisited as new information emerges, preserving the history of how your understanding evolves.

The result is more than a research report. It's a persistent, evidence-based context for product decisions.

And there's one principle at the heart of Proofrun: AI investigates, challenges, and informs. Humans decide.

How would you describe the primary audience of your product?

Proofrun's answer:

Proofrun is built for people responsible for understanding product problems and making informed decisions.

Its primary audience includes Product Managers, Senior PMs, Product Designers, Product Researchers, and startup founders who need to investigate opportunities, evaluate assumptions, and understand the evidence behind their next steps.

It also serves Heads of Product, Product Directors, and Product Operations professionals looking to improve the consistency, traceability, and continuity of Product Discovery across teams.

Proofrun is particularly relevant for organizations where product research, analytics, customer feedback, and decision context are fragmented across different tools and people.

What's the story behind your product?

Proofrun's answer:

Proofrun was born from a problem its founder experienced firsthand while working in technology and product management.

Software development kept getting faster. With AI, building products became easier than ever. But understanding which problems deserved attention, evaluating competing hypotheses, and keeping decisions grounded in evidence remained difficult.

Research was scattered across documents, dashboards, conversations, and people's memories. Valuable context could disappear as teams moved forward.

The question became: what if Product Discovery could remain useful long after the initial research was completed?

That idea became Proofrun.

Built around the concept of Living Discovery, Proofrun aims to preserve the evidence, uncertainty, and reasoning behind product decisions, while keeping that understanding open to revision as new information emerges.

Because building faster only creates value when teams understand where they're going.

Which are the primary technologies used for building your product?

Proofrun's answer:

Proofrun is built with a modern, cloud-native architecture designed for AI-assisted research and continuous Product Discovery.

Its main technologies include:

  • Next.js, React, and TypeScript for the web application.
  • Python for the research and agent orchestration engine.
  • Amazon Web Services (AWS) for cloud infrastructure and execution.
  • Amazon Bedrock for AI-powered research and analysis.
  • PostgreSQL and Amazon DocumentDB for structured and document-oriented data.

The architecture separates the product experience from the research engine, supporting structured investigations, evidence management, and ongoing Discovery reassessment.

Who are some of the biggest customers of your product?

Proofrun's answer:

Proofrun is a newly launched platform, currently being tested by product professionals and early users.

We're actively gathering feedback from Product Managers and product leaders to refine the experience and validate real-world use cases.

We don't have publicly announced paying customers to list yet.
