Verdant Signal is a free browser colony simulation played on desktop or tablet. Every colonist is an autonomous agent with rolled ability scores and a real personality: they cultivate xenocrops, form bonds, barter supplies, invent field technology, hold elections, and stand watch against alien scavenger incursions. Found a biosphere colony or assemble a scavenger crew; your colony persists in your browser and remembers itself between visits.

Is Verdant Signal free to play? Yes — free in a desktop or tablet browser, no download, no account, no ads. Every colonist is an autonomous agent whose rolled stats and personality drive its decisions. The deterministic simulation runs locally; optional language-model channels enrich expressive text. Your colony persists in browser storage and returns with a recap. It is single-player, in a world of neighbouring colonies your crew can encounter, raid, and remember.
