Hanko vs Resend
A side-by-side editorial comparison of Hanko and Resend — release velocity, themes, recent moves, and the top alternatives to consider.
Hanko vs Resend: at a glance
What is Hanko?
Hanko ships Firebase migration support and tightens session management — targeting auth stack replacements.
Hanko is a passkey-first authentication platform available as open-source self-hosted or cloud-managed. Monthly releases show consistent refinement across the auth stack: stronger passcode options, inactivity-based session termination, session token transparency, device trust handling improvements, and expanded OAuth/OIDC integration. The June 2026 Firebase Scrypt hash import signals an active effort to reduce friction for teams migrating away from Firebase Auth.
What is Resend?
Resend's broadcast editor now compresses and converts images on upload.
Resend ships something almost weekly, mostly API surface: usage limits, broadcast duplication, clicked-link retrieval and headless webhooks all landed within a month. Distribution runs alongside, with Vercel v0, Stripe Projects and Laravel Cloud able to provision Resend inside their own setup flows. The October 19 release is a rare editor-side change: large images are compressed automatically, and WebP, HEIC and SVG files are converted to formats email clients render.

Hanko ships Firebase migration support and tightens session management — targeting auth stack replacements.
◆ Current state
Hanko is a passkey-first authentication platform available as open-source self-hosted or cloud-managed. Monthly releases show consistent refinement across the auth stack: stronger passcode options, inactivity-based session termination, session token transparency, device trust handling improvements, and expanded OAuth/OIDC integration. The June 2026 Firebase Scrypt hash import signals an active effort to reduce friction for teams migrating away from Firebase Auth.
◆ Where it's heading
The consistent themes across these releases are session management hardening, migration tooling, and auth protocol breadth. Custom OAuth connections, user metadata via Admin API, Firebase import, and OIDC updates together sketch a product trying to compete with established auth platforms (Auth0, Clerk) on flexibility and self-hostability. The monthly cadence is execution-focused — incremental improvements rather than architectural shifts.
◆ Prediction
The next likely moves are broader migration support (other providers beyond Firebase, e.g. Supabase Auth or Cognito) and enterprise session controls such as SAML or organization-level device trust policies. Custom OAuth was the groundwork; SAML is the common next ask.
Resend

Resend's broadcast editor now compresses and converts images on upload.
◆ Current state
Resend ships something almost weekly, mostly API surface: usage limits, broadcast duplication, clicked-link retrieval and headless webhooks all landed within a month. Distribution runs alongside, with Vercel v0, Stripe Projects and Laravel Cloud able to provision Resend inside their own setup flows. The October 19 release is a rare editor-side change: large images are compressed automatically, and WebP, HEIC and SVG files are converted to formats email clients render.
◆ Where it's heading
The main arc is still API parity plus platform embedding, which points to Resend being provisioned and run mostly by platforms and agents. The editor work, a table component in September and image handling now, shows Resend also closing gaps for marketers who build broadcasts by hand. Both tracks widen who can send through Resend without leaving their tool.
◆ Prediction
Expect more hosting and framework platforms to get one-click Resend connections; the editor's next step is less clear from these entries.
