Let's Encrypt
Free TLS certificates from the nonprofit Internet Security Research Group.
Verdict
Let's Encrypt issues free TLS certificates. The homepage says it is a nonprofit providing free certificates, and it cites more than 700 million websites. There is nothing to buy. You still need a server or a host that can request and renew the certificate.
- Who it is for
- Anyone running a website who needs a certificate and can renew it automatically.
- Free tier
- TLS certificates are free. The homepage says so. Checked 14 Oct 2026.
- Pricing note
- No paid plan. Sponsorship and donations are how the nonprofit is funded. That is not a fee for a certificate.
