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
    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 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.
  • 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 Zeplinโ€™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.

Questions & Answers

As answered by people managing Zeplin and 1DevTool.

What makes your product unique?

1DevTool's answer:

1DevTool is the only developer workspace that combines a browser, AI prompt editor, persistent terminals, smart notifications, and activity logs in one app โ€” and sends console errors, network requests, and screenshots to your AI agent in a single click. No copy-pasting. No tab-switching. Developers save 40+ minutes every day without changing how they work.

Who are some of the biggest customers of your product?

1DevTool's answer:

Indie developers and solo founders Freelance full-stack developers AI-assisted development teams

Why should a person choose your product over its competitors?

1DevTool's answer:

Cursor and GitHub Copilot are great AI editors โ€” but they don't eliminate the switching between Chrome, terminal, and AI tools that kills your focus. 1DevTool does. It's also a one-time $29 payment. No monthly subscription. No vendor lock-in. You own it forever.

Which are the primary technologies used for building your product?

1DevTool's answer:

Electron, Node.js, React

How would you describe the primary audience of your product?

1DevTool's answer:

Full-stack developers and indie hackers who use AI coding agents (Claude, Codex, Gemini) daily and are frustrated by the constant context-switching between their editor, browser, terminal, and AI chat. Especially solo developers and freelancers who want a lean, focused environment without paying for 5 separate SaaS tools every month.

What's the story behind your product?

1DevTool's answer:

Built by a solo indie developer who was tired of Alt-Tabbing 50 times a day just to debug one bug. The idea was simple: what if your browser, terminal, and AI assistant all lived in the same window? 1DevTool was born from that frustration โ€” a no-nonsense workspace built for developers who want to stay in flow and ship faster.
