Build beautiful apps and websites incredibly fast. Drag and drop your own components, integrate with your codebase. Break through the no-code ceiling.
Plasmic is a visual builder for the web.
You can use it to build web apps and websites, and you can use it as a visual content management system.
It lets anyone, regardless of coding background, design and build rapidly--code optional.
At the same time, it is powerful, with a deep feature set that scales to complex projects. And with codebase integration, it removes the ceiling typically associated with low-code tools.
Some highlights of what Plasmic provides:
- Full design freedom and speedy modern design tool UX.
- Create rich interactions and behavior.
- Connect with arbitrary data source and backend integrations.
- Content creator mode: give specific collaborators a more simplified and restricted editing experience.
- Deep collaboration with multiplayer, branching, cross-project imports, and multi-workspace organizations.
- Integrate with codebases for unlimited flexibility and scale.
- Drag/drop and visually manipulate your own React components—design systems, interactions, data, behavior, and more. Extend and customize Studio with custom controls.
- Import designs from Figma, translating its proprietary vector document format into DOM/CSS.
- Powerful abstractions like components, variants, slots, composable state management, and more that promote composition and let you build and maintain at scale.
- High-performance and high-quality codegen. Supports static site generation, automatic image optimization, layout shift reduction, and more.
- Customizable design system components. Powered by react-aria. Most component libraries give you variables to tweak, but here you can completely change the structure and layout.
- Deploy/host/export anywhere
- End-user auth and permissions
- Versatility in use cases. The line between websites and web apps can be blurry.

This is one popular use case of Plasmic.
Step 1. Install Plasmic into your codebase (exact package depends on your framework).
npm install @plasmicapp/loader-nextjs
Step 2 (optional). Make components from your app or design system available for drag-and-drop in the visual editor:
// Take any component from your app or design system...
export default function HeroSection({ children }) {
return <div className="hero-section">{children}</div>;
}
// ...and make it available for drag-and-drop, along with any props you want to
// expose.
PLASMIC.registerComponent(HeroSection, {
props: {
children: "slot",
},
});Step 3. Add placeholders that render pages/components made in the visual editor anywhere in your app:
// pages/index.tsx
import {
PlasmicRootProvider,
PlasmicComponent,
} from "@plasmicapp/loader-nextjs";
import { PLASMIC } from "../plasmic-init";
// Here we fetch dynamically on the client, but you can also fetch and render
// components server-side in SSG/SSR frameworks, such as via getStaticProps
// in Next.js.
export default function IndexPage() {
return (
<PlasmicRootProvider plasmic={PLASMIC}>
<PlasmicComponent component="Summer22LandingPage" />
</PlasmicRootProvider>
);
}Step 4. Non-developers (or developers!) can now create new pages, sections, or components that ship directly into the app/website.
Step 5. When you hit Publish, changes get picked up via webhooks that trigger rebuilds, or more specific mechanisms such as incremental static revalidation or dynamic fetching from the Plasmic CDN.
Plasmic is used by companies ranging from Fortune 500s to boutique brands to solo makers. It's used for websites ranging from headless commerce storefronts to marketing websites to logged-in app content.
Check out the Case Studies and Community Showcase.
Note: you do not need to integrate Plasmic with a codebase. This is core to using Plasmic as a CMS, but you can build complete apps and websites without this, entirely within Plasmic.
Read the full technical overview.
You can register your own arbitrary custom React components for use as building blocks within Plasmic Studio. Learn more about code components.
Besides the Headless API, you can also generate React code into your codebase. This is a powerful way to use Plasmic as a UI builder for creating rich interactive web applications—one example of this is Plasmic Studio itself. See the application development tutorials to learn more.
One common issue we see is mismatched or duplicate versions of packages.
@plasmicapp packages can depend on each other.
Each package always has an exact version of its @plasmicapp dependencies.
This is because we want to ensure that all packages are always in sync, and that we don't end up with a mismatched set of packages.
Packages like @plasmicapp/host must also be deduped, since functionality such as registerComponent make use of globals and side effects, so with multiple versions you could end up using the wrong "instance" of this package.
Additionally, types can be tightly coupled across multiple packages.
Unfortunately, npm and yarn make it easy for you to end up with mismatched versions and duplicate versions of packages.
Use the npm list command to ensure that you have unique deduped versions of packages.
Furthermore, issues can be "sticky," since npm/yarn are stateful.
At times, you may need to rely on npm dedupe, or removing and reinstalling Plasmic packages (including @plasmicpkgs packages), resetting package-lock.json/yarn.lock, in order to unwedge npm/yarn.
@plasmicpkgs (the built-in code component packages) have @plasmicapp packages as peer dependencies,
and these specify ranges rather than exact versions--this is to offer some flexibility for developers to use the core package versions they need, while still using @plasmicpkgs.
Note: exact versioning does not imply that every package increments versions for every release.
Packages are only incremented if they or their dependencies have changed.
Incrementing versions, including those referenced in dependencies and devDependencies, is done automatically when our deployment scripts run lerna version patch --exact...,
which detects whether a package has changed since its last git-tagged release.
This repo contains the code for all Plasmic component store packages (@plasmicpkgs/*), client libraries/SDKs (@plasmicapp/*), and examples (under the examples/ dir).
(For hacking on code components or plasmicpkgs, see specific additional instructions further down.)
We use lerna to help us manage dependencies among all the packages.
In general, we follow the "fork-and-pull" Git workflow.
- Fork the repo on GitHub
- Clone the project to your own machine
- Commit changes to your own branch
- Push your work back up to your fork
- Submit a Pull request so that we can review your changes
NOTE: Be sure to merge the latest from "upstream" before making a pull request!
yarn lerna bootstrap # inter-links all the lerna-managed packages together
We also make use of Verdaccio to locally test packages. This just stands up a local npm registry that you can publish your test packages to.
yarn global add verdaccio
verdaccio & # Runs the verdaccio server at http://localhost:4873
You'll need to update the verdaccio config file, at ~/.config/verdaccio/config.yaml, to instruct verdaccio to not use npmjs for our test packages:
packages:
'@plasmicapp/isomorphic-unfetch':
access: $all
publish: $authenticated
unpublish: $authenticated
proxy: npmjs
'@plasmicapp/react-ssr-prepass':
access: $all
publish: $authenticated
unpublish: $authenticated
proxy: npmjs
'@plasmicapp/*':
access: $all
publish: $all
unpublish: $all
'@plasmicpkgs/*':
access: $all
publish: $all
unpublish: $all
Then kill and restart the verdaccio server:
verdaccio &
Finally, in order to publish, you may be required to have a user login. Create this one-time in your Verdaccio--it doesn't matter what user/password/email you input:
npm --registry=http://localhost:4873 adduser
# Step 1.
# Make some changes! Let's say, to @plasmicapp/host.
# vim packages/host/src/registerComponent.ts
# Step 2.
# Publish a specific package to verdaccio.
# This unpublishes YOURPKG and its dependencies from your verdaccio, re-builds them, and publishes them to your local
# verdaccio.
# Note that this does not bump versions!
# We are using nx under the hood, so if your dependencies haven't changed, this should be fast.
# In this example, even though we edited @plasmicapp/host, we can just think about publishing the "root" package(s) we're ultimately installing into the test app, in this case @plasmicapp/loader-nextjs.
yarn local-publish @plasmicapp/loader-nextjs &&
# Or publish all packages to verdaccio. This will take longer.
# yarn local-publish
# Step 3.
# Go to the package you're testing, e.g. test-host-app.
# You can quickly create a test target app with `npx create-plasmic-app`.
cd ~/test-host-app &&
# Step 4.
# Simply blow away existing package manager state, to ensure we're getting your locally published versions of packages.
# This is the simplest approach if this is a throwaway test app where you don't need to maintain version lock state.
rm -rf node_modules package-lock.json yarn.lock &&
# Or, to be more surgical: you can delete anything that pulls in any @plasmicapp/@plasmicpkgs packages.
# In this case, we want to remove anything that depends on the @plasmicapp/host package we updated.
# npm un @plasmicapp/loader-nextjs @plasmicpkgs/plasmic-rich-components
# Step 5.
# Delete any framework-specific caches, such as these for Next.js and Gatsby.
# Frameworks might cache node_modules packages in ways that won't pick up your changes, depending on how you carried out the prior steps.
rm -rf .next/ .cache/ &&
# Step 6.
# (Re-)install the necessary packages, from your local verdaccio.
# These will pull in the changes you made to @plasmicapp/host.
# Note: this proxies to npmjs.org for packages that aren't published locally to verdaccio.
npm i @plasmicapp/loader-nextjs @plasmicpkgs/plasmic-rich-components --registry=http://localhost:4873Check that the versions in your package.json are also not holding back any plasmicpkgs and plasmicapp versions!
In general, you probably want all @plasmicapp/@plasmicpkgs packages to be installed from your local verdaccio, rather than having some installed from npmjs.org and others installed from local, since you want to prevent mismatched and duplicate package versions.
For a few packages like react-ssr-prepass, these are not currently integrated into the NX workspace system. This is because Lerna doesn't work with git submodules. You can publish these as individual packages with, for instance:
cd plasmicpkgs/SOMETHING
yarn install # Not included in the workspace install
yarn publish --registry=http://localhost:4873
# Or with more options: yarn publish --canary --yes --include-merged-tags --no-git-tag-version --no-push --registry=http://localhost:4873 --force-publish
The above general contribution instructions also apply to plasmicpkgs, so read that if you haven't done so.
Before starting, we recommend reading our docs for Code Components:
- [Docs on code components][code component docs]
Ignore this if you are just updating an existing package.
To create a new plasmicpkg, the easiest approach is to clone one of the existing packages (like react-slick) and fix up the names in package.json and README. Then author your registration code in src. Please use yarn for package management.
The directory name should be the same name as the main package you'll be using to import the React components. Your package must be named @plasmicpkgs/{package-name} and start with version 1.0.0.
@plasmicpkgs/* packages should depend on @plasmicapp/* packages as both peer dependencies and dev dependencies.
You should always use a permissive range in peerDependencies, so that users can install your @plasmicpkgs/* package with whatever their current versions are of @plasmicapp/* packages.
Dev dependencies should specify the most recent version of the package.
In general, @plasmicpkgs/* depend on @plasmicapp/host because it is the package that is used by Plasmic Studio to register components.
But you may also need others such as @plasmicapp/data-sources.
So a typical package.json might look like this:
{
"devDependencies": {
"@plasmicapp/data-sources": "0.1.53",
"@plasmicapp/host": "1.0.119",
"@size-limit/preset-small-lib": "^4.11.0",
"@types/node": "^14.0.26",
"size-limit": "^4.11.0",
"tsdx": "^0.14.1",
"tslib": "^2.2.0",
"typescript": "^3.9.7"
},
"peerDependencies": {
"@plasmicapp/data-sources": ">=0.1.52",
"@plasmicapp/host": ">=1.0.0",
"react": ">=16.8.0",
"react-dom": ">=16.8.0"
},
"dependencies": {
"memoize-one": "^6.0.0"
}
}The package must work for both codegen and loader users. This means that the register functions must have a optional parameter for the loader. It should also have an optional metadata parameter for users that want to use their own custom metadata.
export function registerFooBar(
loader?: { registerComponent: typeof registerComponent },
customFooBarMeta?: ComponentMeta<FooBarProps>
) {
if (loader) {
loader.registerComponent(FooBar, customFooBarMeta ?? FooBarMeta);
} else {
registerComponent(FooBar, customFooBarMeta ?? FooBarMeta);
}
}Feel free to create wrapper components if it makes the final result better for the user. You also don't need to register all the props available for the component, only the ones that will be used in the studio.
Remember to export any wrapper components/types used to register the component. Everything should be also exported from the index.ts file, so all the imports are from @plasmicpkgs/{package-name}.
We recommend a registerAll() function for an easy way to register all the available components in the package.
Checklist to test:
- Does your component behave well in the Studio in both editing and live preview modes?
- Do all of the props and slots work correctly?
Remember that your package will be used by a wide variety of users, so it's important to have easy-to-use components, with good descriptions.
After testing in the Studio, it's also good to test both the available code options: loader and codegen. Testing codegen ensures your import paths are correct.
