You send, you’re in.
Sendity lets users sign up, sign in, or confirm important actions by sending one short code. Use it for login, lead capture, checkout accounts, gated content, and other flows where the next step should feel effortless.
No passwords. Fewer failed forms. Your app decides what happens next.
WHERE USERS DROP OFF
Every extra step can stop the next action.
Users lose momentum when they create passwords, fix form errors, wait for verification emails, or repeat a login they do not remember. That friction can block trials, purchases, downloads, consultations, and other moments where someone was ready to move forward.
Passwords interrupt intent
Password rules, confirmations, and resets add work exactly when a user wants to try your product, start a checkout, or come back quickly.
Forms fail in small ways
A mistyped email address, unclear validation message, or required field can turn real interest into an abandoned sign-up.
Emails are not always reliable
Verification emails bounce, land in spam, arrive late, or get copied incorrectly. Every delay cools down the moment.
THE SENDITY MOMENT
One send-the-code action. Your app stays in control.
Sendity turns sign-up, sign-in, and confirmation moments into a short guided flow. Users get one simple action and stay focused on the next step.
For developers, the trust boundary stays on your side: your backend verifies the signed result, keeps ownership of users, sessions, roles, permissions, CRM logic, fulfilment, and decides what happens next.
-
Show a short code
Place the Sendity Client wherever users are ready to move forward: sign-up, login, checkout, gated content, onboarding, or a contact request.
-
User sends it back
The user sends the code from a channel they already control. Sendity matches the challenge, sender channel, allowed origin, expiry, and replay protection.
-
Your backend verifies the result
Your server or framework adapter verifies the signed result before trusting the event. Then your app decides what follows: create an account, open a session, unlock content, trigger checkout, or route a request.
USE CASES
Built for more than one login screen.
Use Sendity wherever a user has shown intent and the next step should be fast, clear, and low-friction.
- SaaS trials and freemium sign-ups
- Shop accounts and returning-customer login
- Lead capture, ebooks, webinars, and waitlists
- Coaching, courses, and consultation requests
- Step-up confirmation for sensitive actions
- Custom onboarding, CRM, and backend workflows
WHY TEAMS USE SENDITY
A smoother path from intent to action.
Sendity helps teams remove friction from sign-up, login, and confirmation flows without forcing every product into the same authentication or marketing pattern.
More completed starts
Reduce the moments where users hesitate, switch context, or abandon a flow before it really begins.
Less support noise
Fewer password resets, fewer “I didn’t get the code” moments, and fewer login explanations.
Flexible next steps
Sendity can hand off to account creation, login, onboarding, checkout, downloads, sales follow-up, or your own backend workflow.
Your system stays in control
Your application keeps users, sessions, permissions, CRM logic, fulfilment, and customer ownership.
INTEGRATION
Start with Cloud. Add the Client. Keep your app in control.
Sendity Cloud handles the verification backend. Your application renders the Sendity Client and verifies the signed result through your backend or framework adapter.
No Sendity server to operate
Use the hosted Sendity API for challenges, channel routing, proof matching, and token issuance.
Works with your existing auth flow
Keep your users, sessions, roles, redirects, and application logic where they already belong.
Laravel adapter available
Use the Laravel adapter for server-side verification and session handoff without building the default flow from scratch.
1. INSTALL THE ADAPTER
Add the Laravel auth package to your application.
composer require sendity/laravel-auth:^0.12. RENDER THE CLIENT
Place Sendity where sign-up, sign-in, or step-up verification should happen.
<x-sendity />The adapter handles the default proof callback, signed-result verification, replay protection, and session handoff. Customize account creation, redirects, and advanced flows in your Laravel code.
More framework adapters are in preparation. Need one for your stack? Request an adapter or submit an implementation on GitLab.
CLOUD BY DEFAULT, OPEN SOURCE BY DESIGN
Launch hosted. Inspect everything.
Sendity is open source across the browser Client, framework adapters, and server packages. Use Sendity Cloud for the fastest path to production, or self-host when your team needs to operate the verification backend itself.
Cloud in minutes
Create a Cloud app, allow your origins, copy the Public App ID, and integrate the Client or Laravel adapter.
Inspectable by your team
Review the Client, adapters, and server packages before using Sendity in a production auth flow.
Self-host when needed
Run your own Sendity backend if your compliance or infrastructure requirements justify the operational overhead.
