Energy use, daylight, structural behavior, acoustics, and carbon are different questions, and this page keeps a tool for each of them. About half name Windows, and about half name the browser. A Mac-only or Linux-only setup is uncommon.
DesignBuilder is a paid trial on Windows for whole-building energy, HVAC, daylight, and comfort studies. Dlubal RFEM 6 and IDEA StatiCa are paid Windows listings for structural analysis and steel connections, and both show public prices. cove.tool is an enterprise quote listing for early energy, daylight, and embodied carbon, on the web and on Windows. Ladybug Tools is free for solar studies, daylight metrics, and energy use intensity on Windows, macOS, and Linux.
Some listings are free to open. Most are paid or quoted. Match the card to the question you need answered, then see whether a price is printed.

Ladybug Tools and Wallacei are free. LightStanza and SimScale are freemium. Ladybug Tools lists Windows, macOS, and Linux. SimScale is the browser listing for CFD, FEA, and thermal studies. LightStanza lists daylight and glare work on Windows, macOS, and the web.
Dlubal RFEM 6, IDEA StatiCa, SCIA Engineer, MIDAS Gen, and StruSoft list structural analysis or finite element work. Dlubal RFEM 6 is a paid trial and IDEA StatiCa is paid, and both show public prices. SCIA Engineer is a subscription. MIDAS Gen is enterprise quote. StruSoft is a paid trial on Windows and the web.
Several listings use the pricing type enterprise quote, including cove.tool, One Click LCA, and MIDAS Gen. Those cards name tasks and platforms and do not show a package price. A blank price is not a free tool.
macOS is uncommon here, and Linux is uncommon too. Ladybug Tools, LightStanza, and Wallacei are the listings that name macOS. Converge is the listing that names iOS and Android, and it also lists the web. Read the platform tags if you need a Mac-native app.
Compare the job first. Energy simulation, daylight, structural analysis, and life-cycle assessment are different kinds of work, and this page publishes listings for each of them. Then compare the pricing type. A freemium browser study and a paid Windows solver can both belong here.
