Collaboration app for UI designers and frontend developers
Zeplin is an application for designers and engineers that facilitates the design process by automatically generating style guides, specifications, and assets. This integration enables your team to receive updates on a Slack channel when new designs are being uploaded, resources are reorganized, and fresh messages/responses from your teammates come in. Zeplin is an application for contemporary designers and interface developers that allows them to collaborate effectively and save time. Designers can quickly convert designs into powerful specifications and guidelines, and developers can access all the resources they need in one place and generate code snippets that match the platform they are working on.
Zeplin is a supplement and web application that works exclusively with Sketch. It compiles all aspects of the selected elements into an interactive form with a specification that simplifies the exchange between design team and programmers. This is so easy to determine with Zeplin. After installing the Sketch extension, you can export any number of screens by selecting the Artboard(s) you want to export and by pressing the shortcut key (Command + E).
Then select the project to which you want to add your specifications and click Import. The Artboards are quickly added to the Zeplin web application, where you can communicate with the properties on each screen to see their specifications. The Guide Box allows you to record more colors and fonts from your screens. This is a useful way for developers to monitor the colors and fonts used in the project, and even export colors to a file such as Objective C or Swift. Zeplin also manages property exporting to PNG and PDF for different device sizes.
Unlike other specification tools, Zeplin's specifications are incredibly perfect, partly because they work with Sketch, a vector tool design designed specifically for UX and UI designers. Sketch's dependence on vector forms allows Zeplin to easily find absolute X and Y property values, as well as their colors and sizes. On the other hand, Photoshop cannot correctly measure the boundaries of an object or position by itself because it is based on layers. Multiple layers can be a challenge for Photoshop specifications.
The user interface is very easy to follow and quite simple. It seems Zeplin is a page application where three columns are displayed. On the left, you have drawings of a specific project, in the middle, you will see a real design, and on the right, you have details. You have a design on the screen, and whenever you want to get more details, you can click on it. Pixels, colors, margins, boundaries, sizes, gradients, just anything.
It is not easy to prepare metric drawings without clicking on items and searching between groups and folders. The sketch allows you to hold the option and mouse around the view to see the basic level of measurement between the elements, but the overall implementation is not far perfect. Developers can observe eye observation, which is not true at all or use a third-party tool such as xScope, but no one can be absolutely sure that any designer or programmer works in the same units (pixels, em, cm, mm). This is a recipe for contradictory measures and may mean that the designer's plans are not properly translated into the final product delivered to users.
When a new project is produced in Zeplin, the designer is asked to determine the pixel density that is used in Sketch. From that moment, Zeplin calculates all the measurements between the elements in a unique and precision unit of the system that is precisely translated into the Xcode AutoLayout constraint unit. Each developer can navigate through the screens to get accurate measurements and ensure that the spacing is perfect as a pixel in the final product.
Designs are not static commands that will never change. Often designers model screens, talk about it with engineers and other designers, receive responses, and collaborate on an agreed solution that can also be changed at any time. Zeplin allows users to record screens directly on the screen and open discussions about specific elements, measures, or interests. The tags are obvious so you will not miss them. Discussions are recorded in the design document itself, where they belong, not in the history of the Stock, by e-mail or verbal conversations. At any time, users can get back to work with various functions and discussions about how the versions are changing.
One of the most powerful and most significant features of Zeplin that many people use is a stylish guide. Zeplin's Styleguide is a way to collect all the colors and fonts used in a project in one place. Colors can be added to the color palette, where HEX/RGB values are named and displayed. Fonts can be added to the font book in which they are named and show their font-family, size, weight, color, alignment, and row spacing.
Zeplin converts units based on their type and project density automatically. For iOS and MacOS projects, measurements are in pt. For web projects, measurements are in px. For Android projects, measurements are in dp.
Free Plan: In a free plan, you must have one of the Zeplin desktop applications installed for your project. Once the app is installed, click the "Create" button in the upper right corner of the Projects screen. Payment Plan: In paid plans, you can also create projects from a web application on the Projects screen.
Zeplin desktop applications are available for: macOS 10.11+ as well as Windows 7+. Zeplin web application runs on Windows, MacOS and Linux devices and is compatible with the latest browsers because it offers the best experience: Chrome 45+, Firefox 45+, Safari 9+ and Edge 13+.
You can see the values as a percentage of distance by holding the Alt/Option key. In addition, you can control which primary layer you want to calculate the percentage by using the ↑, ↓ keys.
Zeplin creates CSS from layers automatically, colors and text styles, but only in web projects. Created CSS will appear in the right panel when you select a layer or when you switch to the "Style Guide" tab.
