Gone are the days when building software meant endless coding, repeated testing cycles, and troubleshooting a common issue repeatedly.
No-code builders have changed the game, especially for SaaS platforms. They help product teams ship faster, marketers launch without dev support, and free up developers to focus on the tasks that move the needle.
In this guide, we will cover a no-code builder's key features, build vs. buy, embedding steps, real-world use cases, and how Unlayer fits in.
What Is a No-Code Builder?
A no-code builder is a visual content creation tool that allows users to build digital assets such as emails, landing pages, pop-ups, or documents without writing a single line of code.
These builders offer drag-and-drop functionality, reusable content blocks (aka custom blocks), and user-friendly WYSIWYG interfaces to make the content creation process intuitive even for non-technical users.
A good no-code tool not only makes things easy for end-users but also offers developers the control and customization flexibility they need behind the scenes.
Difference Between No-Code, Low-Code, and High-Code
All three approaches simplify the development process, but they cater to different audiences and use cases.
No-code tools help non-technical users build emails and pages without relying on a developer.
Low-code is ideal for semi-technical users or developers who want to speed up development by skipping repetitive tasks but still have the ability to inject custom code when required.
High-code helps developers build complex and custom tools from scratch.
Whether you are an end-user or a developer, understanding the difference is essential to finding your perfect match.

Key Features to Look for in a No-Code Builder
Not all no-code builders are the same. Some are made for non-technical teams; they are great for design but limited in flexibility. Others are built with developers in mind, offering control, extensibility, and integration support.
If you are a SaaS company looking for a no-code builder, prefer the one that offers ease of use and backend flexibility.
Here are the key dev-friendly features to consider:
Custom tools & code injections to extend functionality
APIs & webhooks for automation and backend control
Prebuilt templates and reusable blocks for fast content creation and design consistency
Role-based access and security controls for safe collaboration
Choosing a no-code tool with all such features means you are not investing in a locked solution but a flexible one that grows with you.

Build vs. Buy Dilemma: What’s Right for Your SaaS?
Building a no-code tool in-house offers deep control over design, features, customization, and other aspects. But this full control comes with a cost: longer development time, heavier engineering load, never-ending maintenance, and tech debt. It delays your time to market and overburdens the dev team.

On the other hand, buying and embedding a no-code editor is faster, scalable, and cost-efficient in the long run. Instead of spending years building and debugging, you can embed a production-ready editor with prebuilt templates, rich design features, and dev-friendly APIs.

How to Embed a Builder Into Your SaaS App - Seamlessly
Embedding any email/page builder starts with an SDK, which quickly and effortlessly integrates the builder into your UI. However, to tailor the experience for your product and users, you need to connect APIs.
The SDK basically handles the front-end editor experience, like embedding and simplifying development. On the other hand, the APIs manage what happens at the backend, like loading and saving designs or syncing user data.

Open Source vs. SDK: Which Builder Fits Your Tech Stack?

Real-World Example of Embeddable Builders in Action
Today, leading CRMs and marketing tools are enhancing their user experience by directly embedding content builders into their applications. Instead of bouncing their users to external editors, they let them build emails, landing pages, and pop-ups inside their host application.
Embeddable builders not only create a great user experience but also boost engagement, reduce friction, and speed up the launch time.
