About
Flux is browser-based PCB design software (EDA) with an AI hardware design assistant. It combines schematic capture, PCB layout, routing, simulation, and design rule checks in one workspace.
Describe a circuit in plain language to generate a schematic, then refine it in the editor. AI helps research parts, place components, route traces, and review designs. Engineers set constraints and approve the final board.
Teams edit projects together in real time, share comments, manage permissions, and reuse community parts and designs. Live component pricing and availability support sourcing. Export Gerber, BOM, and pick-and-place files for manufacturing.
Import Altium ASCII and Cadence EDIF schematics or KiCad component libraries; these imports do not include PCB layouts. Flux runs in a web browser without a desktop installation.
A 14-day trial includes limited AI usage. Paid plans are required afterward for private-project editing/export and AI.

About
Sensbench is a browser-based circuit and microcontroller simulator for learning, prototyping, and testing Arduino, ESP32, Raspberry Pi Pico, and other supported boards. Users place virtual boards and components on a breadboard, connect circuits, edit sketches, compile firmware, and run it in an emulated microcontroller while viewing serial output and component behavior. It also supports SPICE analog simulation and mixed digital-analog circuits. Guided examples and virtual sensors, displays, LEDs, relays, and other parts are included. An optional AI builder turns a written project request into a parts list, wiring plan, and firmware, while an MCP server lets compatible AI clients operate the workbench. The core simulator is free to use in a web browser; optional AI credits and subscription plans add AI usage and project features. Sensbench also sells physical project kits with pre-flashed boards and guides, including kits designed to connect to Home Assistant over local Wi-Fi.

Pricing
$50/month (billed monthly)
USD. Monthly billing: Explore $50/month; Build $100/month; Pro $250/month. Annual billing (monthly equivalents): Explore $40/month; Build $80/month; Pro $200/month, billed annually. Teams $158/editor/month, or $120/editor/month billed annually. Enterprise: custom pricing.
14-day free trial with limited AI usage; selected plan starts afterward unless canceled. After the trial, editing or exporting private projects and using AI require a paid plan. Public-project/community access remains available. Pro trial requires a $250 hold (monthly) or $200 hold (annual). AI usage is metered in Agent Compute Units (ACUs). Explore includes 40 ACUs/month; Build 120; Pro 400. Optional pay-as-you-go AI usage on Build and Pro costs $2/ACU; Teams supports optional pay-as-you-go and pooled usage.
