What it does
Heartmorrow is a fully local dating + world simulator powered by your own language model. You build the cast and the world they live in, then *live* a relationship sim in your browser: go on dates with streamed, in-character dialogue, text back and forth on an in-game phone, play minigames, shop for gifts, and watch relationships grow, drift, define themselves, or fall apart across a living in-game calendar.
Get started
./install.sh
# one-time setup (downloads Node locally, installs, seeds)
./run.sh
# start the server + web client You need: Node.js 24+ — the server uses Node's built-in node:sqlite (stable, flag-free on; pnpm — the repo pins [email protected] via packageManager, so running corepack; *(Optional, but basically needed to actually play)* an OpenAI-API-compatible LLM server, either local or a cloud API.
