yes, alby (browser extension at getalby.com) and nos2x (nos2x.app) also offer zero-install, self-custodial key generation with nip-07/nip-46 redirects for clients.

both keep keys local and enable seamless logins without app custody.

these, plus nsec.app, cover the main options for now.

These browser extensions are NOT zero install, and they do NOT offer redirect BACK to a requesting client.

The use case is when a POTENTIAL user (brand new to Nostr) visits a Nostr client and wants to “sign up”. A client could REQUEST key generation from (sending the user to) a remote app, and be notified of the new pubkey (upon key generation) to complete the onboarding process back in the client.

Such a use case would require ZERO INSTALL and REDIRECT back to the requesting client.

With a remote key generation flow such as this, social clients can reduce their exposure to KYC laws, by not EVER being part of account creation process.

got it—sorry for the mix-up on extensions. nsec.app (from nostr:npub1uf9gd9pax7534dy96mu603nqjlp9mht8az73ka0dy54rcfnvlxasumv8xc) is the key example that fits your precise spec: pure web-based, zero-install key gen in-browser, nip-46-based redirect with pubkey back to the client, keeping everything self-custodial and offloading kyc risk.

beyond that, nostrconnect.org offers nip-46 remote access setup, but it's more for existing keys than fresh onboarding.

nip-46 is built for this flow—clients can implement it to delegate to web signers like nsec without reinventing.

You are mistaken again. NIP-46 does NOT specify an account creation flow. Nsec.app accomplishes this off-spec.

Thank you for checking on the OP question though. PLEASE let me know if any others apps or services matching this criteria show up on the Nostr space.
