What is OST Linker?

The AI-powered recommendation engine behind OpenSourceTogether.

It analyzes open-source projects and matches them to contributors — so you find your next contribution in seconds, not hours.

Getting Started

cp .env.example .env              # set DATABASE_URL, tokens, optional host ports (see file + AGENTS.md)
make setup                        # uv sync + compile Go binaries
npm ci                            # Prisma / Node (needed before db-init)
docker compose up --build -d      # Dagster + API + db (default host: Dagster :3000, API :8000 unless overridden in .env)
make db-init                      # Prisma schema + seed
make ci-check                     # Python parity with CI quality job (before a PR); full CI is broader — see AGENTS.md
