    What the licence lets you do

    GPL-3.0

    Copyleft (GPL, AGPL, MPL): derivative work must stay open. AGPL also covers software offered over a network, which blocks most closed SaaS wrappers.

    This matters most when you plan to sell a hosted version. A permissive licence means anyone — including a competitor with more capital — can do the same, so your defensibility has to come from distribution, support or data, not from the code.

    What Tasmota means for your idea

    Tasmota is shipping code consistently, so a buyer comparing your product will find a maintained free option. Price and position against the total cost of self-hosting it, not against the paid incumbent's list price.

    Winnable, but differentiation is not optional. Pick one underserved segment and be visibly better for it rather than competing feature-for-feature with a free tool.
