Zeplin features and specs

  • 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

Possible disadvantages of Zeplin

  • 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.

    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.

    Good system

    I'm on the free plan, all the basic options to run a project are there and the mail notification/comment system works very well. The user interface is good. My only complaint is that you cannot have more than one person assigned to a task. It's their philosophy and they say that if you want to have more assignees you should either duplicate the task or create subtask (only for paid plans).

    Competitors: Jira, Trello
    Pros:    User friendly interface|Free basic plan
    Cons:    Cannot have more people assigned to a task
