Bio, recent activity, top projects, and outreach channels in one call. **`find_similar_projects`** — landscape mapping from a seed repo with top contributors surfaced, so you can pivot from a project to its maintainers in one step.

  • RelayLaunch
    RelayLaunch LLC
     ● healthy

    RelayLaunch helps local service businesses get found in AI-assisted search, get booked, and keep the customers they already have, in that order. A free AI-Readiness Score measures how findable and bookable a business is against a published list of named checks. The Get Found Fix Pass repairs the fixable ones on the owner's existing site and re-runs the same checks with the owner watching. Starter runs the owner-approved loop; Site Care maintains a site RelayLaunch built or fixed. Every action is owner-approved before it reaches a customer. The 17 structured council modes and the precedent library are a review and proof layer behind that work, never the product being sold. Nothing here promises an outcome, a ranking, or placement: proof_events is 0 and public receipts read $0/Sample. Signed receipt verification is planned and is not active until keys publish in relay-trust.json.
