If it's been useful to you and you'd like to support the project, you can leave a tip via Buy Me a Coffee. There's no recurring commitment, donations are completely optional, and the site never paywalls features, runs ads, or sells data.
Infrastructure (Mapbox tiles, Vercel hosting, Supabase, Resend email, domain renewal, occasional SMS costs) and time spent moderating submissions and tuning data sources. We'll publish an annual cost-vs-donations report after the first year.
