Edge Functions run server-side logic geographically close to users, offering low latency and great performance.
Global presence
Edge functions run globally or can be pinned to your database's proximity
Automatic scaling
Seamlessly scale with usage without any manual tuning
Secure
Scale with confidence with SSL, Firewall and DDOS protection built in
Debug and monitor with
built-in observability
