Best Cloud-Based PCB Design Software in 2026

Last updated: October 27, 2026

Key Takeaways

• “Cloud PCB design” can mean a browser-based editor or a cloud service connected to desktop design software.
• Compare live collaboration, offline access, revision history, permissions, and what the cloud service stores.
• KiCad is a desktop tool; teams can add cloud review and revision management through a separate workflow such as CADLAB.
• Choose a product with a pilot that includes a schematic, a board, a review, and a manufacturing handoff.

Cloud PCB design software compared

Cloud PCB software ranges from browser-based design tools to services that manage desktop projects or provide version review. The table separates those roles.

Flux: browser-based real-time collaboration

Flux (flux.ai) is an AI hardware engineer that works in the browser. Its AI agent plans a design, picks real parts from datasheets, draws the schematic, places and routes the board, and runs electrical rule checks (ERC) and design rule checks (DRC) as it works.

The team edits the same project in real time and leaves comments. Each project can be shared by link. The parts library has 734,000+ public parts with live pricing and availability. Flux imports KiCad, Altium, EAGLE, EasyEDA, and PADS projects with layout included.

Flux exports Gerber, IPC-2581, ODB++, BOM, pick-and-place, and STEP files. The collaborative PCB design guide and Flux for teams describe team workflows.

Flux runs in the browser and needs an internet connection; it has no offline mode. Long-standing Cadence or Siemens flows (custom libraries, scripts, PLM hooks) need a migration period. Flux has a free plan to start; see Flux pricing.

Altium Develop: best for a cloud workspace around Altium projects

Altium 365 is a cloud platform for electronics product development and collaboration. Altium describes it as connecting design, supply chain, manufacturing, and other team roles. It is not a standalone schematic editor; it connects Altium Designer projects with shared workspace reviews, comments, and version history.

EasyEDA Pro: best for online design with a desktop option

EasyEDA Pro offers online schematic and PCB design and a desktop client. EasyEDA describes component libraries, interactive routing, team collaboration, cloud-based design data, and a cloud-to-factory workflow with manufacturing services. Its product pages distinguish online work from the desktop client's local and offline options.

OrCAD X OnCloud: best for cloud data management with OrCAD X

Cadence OrCAD X OnCloud is described as a cloud-native PCB data-management platform. Cadence lists centralized access to designs, libraries, and data, plus real-time team collaboration, design review, library creation, and version control. OrCAD X also includes desktop design products.

Upverter: best for browser-based design workflows

Upverter's active product page describes a modular, web-based tool for PCB design, schematics, automated routing, and 3D preview. Its website also offers board ordering and browser-based design sharing.

CADLAB: best for visual revision review

CADLAB is a Git-based version-control and review tool for PCB files, not design software. It displays revisions online, shows visual differences, and supports interactive annotations for design review. CADLAB lists GitHub, GitLab, Bitbucket, Gitea, and self-hosted integrations; design editing remains in a separate EDA application.

KiCad with a cloud workflow: best for open-source teams

KiCad is free, open-source EDA software for desktop schematic and PCB design. The editor can be paired with a separate cloud service or Git host for sharing and revision history. CADLAB describes online visual review for PCB project revisions.

This option separates design work from collaboration infrastructure. Teams can keep their chosen desktop editor while setting up access, review, and revision history in another service. That flexibility means the team must define how it stores project files, resolves changes, and grants access.

How to choose cloud PCB software

First decide whether you need a browser editor or cloud services connected to desktop software. A browser editor can reduce local installation work, while a cloud platform can share data from a desktop design environment. The labels alone do not show which steps run online or which still need a local application.

Next, map the design workflow. Include schematic capture, component selection, PCB placement, routing, review, revision history, and manufacturing output. Ask which activities happen in the same project and which require a separate service. Include library ownership and external collaborators in the map.

Check offline needs before selecting a tool. Some products offer local desktop applications, while their cloud collaboration features require a network connection. Ask whether engineers need to continue a design during travel, at a lab with restricted access, or under a customer network policy.

Review permissions and project ownership. Identify who can see, edit, comment on, or share a design. Ask how external collaborators receive access and how the team removes it when a project ends. Verify current controls from product documentation instead of assuming every cloud workspace uses the same model.

Finally, test version history. Create a change, compare it with the prior revision, and restore or branch the design if the workflow supports it. Agree on how the release revision is marked and how manufacturing files are generated from that version.

A short pilot should include a real design, two reviewers, and one manufacturing handoff. Record how long each task takes and where engineers need extra steps. Use the pilot results to compare the tools against the team's requirements rather than comparing feature names in isolation.
