Open in Busymate DevTools (one-tap)NewThe partner integration guide for the one-tap 'Open in Busymate DevTools' hand-off — drop your users into Busymate DevTools, signed in as themselves, in ONE tap. The confirmed same-device PKCE contract (mint verifier + S256 challenge, broker /start, open bmdev://auth/federation?code=…#fed_verifier=…, /exchange for a real-email session), how to onboard a partner with one upsert_federation_client admin action, and the BMFederationExample reference implementation.
Federate a Supabase userbaseNewThe partner guide for the 'supabase' federation profile — a partner whose product runs on its OWN Supabase project auto-logs (and auto-creates) its users into Busymate DevTools. The asymmetric-signing-keys (ES256/RS256 JWKS) prerequisite + the onboarding preflight, the one-admin-action registration (supabase_url / email_trusted / email_linking_trusted / capped_role / max_token_age), and the exact /start wire contract with the user's live Supabase access token as the supabase_token assertion.
