The simplest API for email,
OTP verification, and job scheduling.
Bring your own SMTP. One API key to send transactional emails, verify users with OTP codes, and schedule recurring webhooks or emails. Open source, self-hostable, and free no per-email fees, ever.
curl http://localhost:8080/send -H "X-API-Key: lfy_your_key" -d '{ "to": "hello@example.com", "subject": "Welcome", "body": "Thanks for signing up." }'
From zero to delivery in five minutes
No vendor accounts. No monthly fees. Just your SMTP, one API key, and a curl command.
Plug in your SMTP
Sign in with Google or GitHub, then add the SMTP credentials you already have. Gmail, Zoho, your hosting provider. Your password is encrypted with AES-256.
Get one API key
A single key covers email sending, OTP verification, and cron job scheduling. Drop it in your environment. No SDK required.
Send or schedule
One POST to send an email. Another to schedule a recurring webhook. Every delivery and execution is logged to your dashboard automatically.
Why add another bill when you already pay for email?
Your Google Workspace, Zoho, or hosting plan already includes SMTP. LifyGo plugs directly into it.
No per-email fees. No vendor lock-in.
Self-host on your own server →Core Architecture
One API. Three things you need.
Email, OTP, and cron jobs. No separate services. No separate bills.
Send transactional emails
Send welcome emails, password resets, and alerts through your own SMTP. No per-email fees. No shared IP pools.
Verify users with OTP
Generate cryptographically secure 6-digit codes and verify them in one call. 10-minute TTL. Single use.
Schedule cron jobs
Create recurring webhooks that hit any URL on a cron schedule. Use it to trigger emails, clean databases, or run reports.
