It generates schematics from natural-language prompts, selects and places components, routes traces, and runs design rule checks, taking a project from idea to manufacturable board in one tool. There is nothing to install: projects run in the browser with real-time multi-user collaboration. Core capabilities: - AI copilot for schematic generation, part selection, placement, routing, and design review, including full plan-to-layout workflows from a text prompt - Schematic capture and PCB layout with live design rule checks - Real-time collaboration: multiple engineers can work in the same project simultaneously - Component library with sourcing data, plus BOM and Gerber export for manufacturing - Import support for Altium and KiCad projects Flux is used by startups, hardware teams, and individual engineers as an alternative to desktop EDA tools such as Altium Designer and KiCad, and by teams migrating off Autodesk EAGLE after its retirement in June 2026. As of 2026, Flux has 1.1 million registered builders and 6.4 million projects. Pricing: paid plans from $20 to $158 per month, with AI features metered through compute credits included in each plan. Free 14 day trial to start. ## Flux Reviews ### 1. Flux Made Advanced PCB Design Accessible to Me **Rating:** 5.0/5.0 stars **Reviewed by:** Tyler W. | Founder, Small-Business (50 or fewer emp.) **Current User:** The reviewer uploaded a screenshot or submitted the review in-app verifying them as current user. **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **AI Translated:** This review has been translated from English using AI. **Reviewed Date:** September 10, 2026 **What do you like best about Flux?** What I like best about Flux is that it combines design assistance with teaching in a way I haven’t found anywhere else. My background is in finance, not electrical engineering, and Flux has let me work through PCB designs I never thought I’d be able to develop on my own while actually learning why the design decisions matter. I’ve already manufactured and successfully tested a four-layer protected power-switch board based on TI’s TPS25983 eFuse, and I’m close to sending out two more designs: one built around TI’s BQ25756ERRVR MPPT solar charge controller, and another using three TI TPS2HC16 automotive high-side switches tied into an onboard Arduino Nano BLE Sense Rev2. The biggest value is how much of the development process I can work through in one place. I can upload datasheets, compare components, work through schematic and layout decisions, ask for routing guidance, estimate BOM costs, interpret manufacturing quotes, build test plans, and then come back with real-world test results and keep iterating. For a self-funded business, being able to do that much work before paying for fabrication, assembly, or outside engineering help is huge. And when I don’t understand something, I can just ask. Instead of stopping to search through tutorials or documentation, Flux can explain the problem in the context of the board I’m actually working on. That combination of building and learning at the same time is what has made the biggest difference for me. It has completely changed what I thought I could realistically do myself. **What do you dislike about Flux?** The biggest downside for me is the hosted interface. For high-precision manual PCB layout and routing, it is still less comfortable and less responsive than working in a traditional locally installed design tool. The other issue is credit usage. Flux is incredibly powerful, but it can burn through credits quickly if you do not give the agent pretty tight guardrails. Sometimes that is entirely on me, but there have also been cases where the agent spends a long time thinking, comes back with essentially the same answer, or ultimately says it cannot complete the task. The feeling of accidentally blowing through your credit budget for the day and then having to stop using the agent until the limit resets is not great. I have learned to be much more deliberate about how I structure requests and when I let the agent take a bigger swing at something, but I still think the usage model can make experimentation feel expensive, especially when the outcome is uncertain. **What problems is Flux solving and how is that benefiting you?** Flux is solving two big problems for me: the knowledge gap between where I am technically and where I need to be to develop more advanced PCBs, and the cost of getting there. My business is self-funded, so hiring an EE or PCB development firm for every design iteration gets expensive quickly. Flux lets me do a huge amount of that work up front myself. Things like component research, schematic decisions, layout, routing, BOM review, manufacturing preparation, test planning, and design tradeoffs before I spend money on fabrication or outside engineering help. The other benefit is that I’m learning while I’m doing it. Instead of just handing a problem off to someone else, I can ask Flux why something should be done a certain way, compare different approaches, and then apply that knowledge to the next design. That has made me much more capable of developing and evaluating my own hardware while also making much better use of the money I do spend externally. ### 2.

This reviewer was not provided any incentive by G2 for completing this review. **Reviewed Date:** September 04, 2024 **What do you like best about Flux?** I like the web based idea of program, implementation of new technology which is AI for PCB design, also worth mentioning is real time price of components **What do you dislike about Flux?** The main feature needs a lot to be considered good. From my experience it was a bit laggy to use **What problems is Flux solving and how is that benefiting you?** Implementation of ai which will result in decreasing work for engineers ### 3. You can work on an electronic project in web with super useful AI copilot **Rating:** 5.0/5.0 stars **Reviewed by:** Vasyl S. | Hardware Developer, Small-Business (50 or fewer emp.) **Validated Reviewer:** Validated through LinkedIn **Source: Organic:** Organic review. This review was written entirely without invitation or incentive from G2, a seller, or an affiliate. **Reviewed Date:** May 18, 2023 At G2, we prefer fresh reviews and we like to follow up with reviewers. They may not have updated their review text, but have updated their review. **What do you like best about Flux?** You can describe your requirements to copilot AI and it can give you a list of components that you will need and explain how to connect them together and even write a code for a firmware if needed. **What do you dislike about Flux?** There are a lot of parts in the library and you can import new parts from KiCAD files but if you need some unique component the part creation process is time-consuming in Flux.ai. **What problems is Flux solving and how is that benefiting you?** I designed PCBs for my clients, and it's easy to share them for review, to get confirmation about details from a client, etc. You don't need to make PDFs, screenshots or send CAD files and a client doesn't need to install a CAD tool or something. - [View Flux pricing details and edition comparison](https://www.g2.com/products/flux-ai-flux/reviews?section=pricing&secure%5Bexpires_at%5D=2026-10-03+10%3A58%3A55+-0500&secure%5Bsession_id%5D=1f43ee47-e4e2-460f-8738-71270a9ab21e&secure%5Btoken%5D=faa5960c50ff71996360e09d8bac64f142d7aad35333d66077ec3c794af224bf&format=llm_user) ## Flux Features **Design** - PCB layout editing - Schematic editor **Tools** - 3D modeling tools - Component placement **Library** - Component libraries **Platform** - Board size - Layers **Customization** - Custom commands - Custom interface ## Top Flux Alternatives - [Altium Develop](https://www.g2.com/products/altium-develop/reviews) - 4.5/5.0 (1,051 reviews) - [Autodesk Fusion](https://www.g2.com/products/autodesk-fusion/reviews) - 4.5/5.0 (509 reviews) - [Onshape](https://www.g2.com/products/onshape/reviews) - 4.7/5.0 (711 reviews)
