If you’re a KiCad user considering a switch to Flux, you might be wondering how the two platforms compare. To help you decide, we’ve broken down the key differences that set Flux apart from KiCad and how it can streamline your design process.
In KiCad, it can take a while to configure your project to get started. Even when you find a reference project, you still need to go through several steps to import the project, libraries, and everything you need get going.
In Flux, all you have to do is open a new project and everything is ready to go! What’s more - all public projects, parts, and modules can be forked and built upon with the click of a button. Similar to GitHub, Flux has been built with reusability in mind from the very beginning.
In KiCAD, library management, schematic editing, PCB editing, and simulation can feel like completely different flows. That can make it hard to keep track of everything and make sure your project stays in sync.
In Flux, the schematic editor, BOM, PCB editor, and simulator all work in one workflow that stays in sync in the browser. There’s also a version control system that makes it easy to revert changes.
In KiCad, you have to maintain multiple libraries which can become extremely time-consuming to keep up to date. When sharing KiCAD designs sometimes projects will break because the reference library isn’t linked.
In Flux, there’s a single unified library that’s being constantly updated and improved upon by the community. This allows you to easily use other people’s vetted parts instead of making your own.
Flux Copilot is the industry's first AI-powered hardware design assistant integrated into a PCB design tool. With its ability to understand schematic designs, component lists, connections, and part information from datasheets, Copilot offers a wealth of knowledge and capabilities that can transform the way hardware design is approached.
In KiCAD, files remain on your computer and sharing and getting feedback often involves sharing screenshots via emails and Slack conversations. Version control is also very difficult, especially when working with others.
In Flux, sharing with contractors, collaborators, clients, and other stakeholders is as easy as sharing a link.
With KiCAD, like all open source software, there is support by community members & contributors which is awesome! However, without centralized support, fixes and features can take easily up to a year.
With Flux, you have access to browser-based software where fixes and new features are instantly deployed to all users and a platform that’s updated frequently based entirely on your feedback.
Making the switch to Flux is easy. Create a Flux account, follow the KiCad to Flux migration tutorial to get your projects into Flux, or follow this video tutorial:
Whether you're migrating from popular EDA applications or starting fresh, mastering high speed PCB design has never been more intuitive. Flux enables teams to design, simulate, and route with real-time AI assistance, so you can spin your next high-speed board with total confidence.
Now, Flux Copilot can learn how you work—your design principles, part selection preferences, schematic style guidelines, and testing workflows—and remember them automatically.
We're excited to unveil our Smart Polygon system in Flux! This powerful capability builds on top of our automatic copper fills to transform how you create and manage custom copper areas in your PCB designs.
With the latest release of Copilot it isn’t just smarter—it’s hands-on, placing components and applying bulk changes to your project instantly. But to get the most out of it, knowing how to craft the right prompt is key.
Creating a manufacturable, error-free PCB is never simple. Every engineer knows that missed details lead to production delays, costly revisions, and project setbacks. But what if you could have the power of a seasoned review team guiding you, 24/7?
If you’re using EasyEDA and are thinking of making the switch to Flux, learn how the two platforms differ and why Flux might be the next step in elevating your PCB design experience.
Flux Files centralizes your project docs, assets, and AI outputs in one tab so your team and AI always have the context they need.
This Spring 2026 updates make hardware design faster end-to-end with a more capable, self-correcting AI agent, improved AI auto-layout that needs less cleanup, sourcing-aware design with real-time pricing and availability, and templates to start from.
