Clawhard Dev Tools

18 read-only developer checks with exact answers: SPF, DKIM and DMARC from live DNS; who can read and write each Supabase table, with fix SQL; cron next runs with DST warnings; JSON repair, outline and path queries; WCAG and APCA color contrast, passing colors and palettes; current time, time zone conversion and meeting slots; and which AI bots a site or robots.txt lets in. No account or API key.
