Edge functions run your app’s custom backend code: the work that can’t happen in the user’s browser, such as talking to other services, processing payments, or sending emails. Think of them as small programs that run on Lovable’s servers whenever your app needs them. There are no servers for you to set up, and they scale automatically with traffic. You don’t create edge functions by hand. Describe what you need in chat, and Lovable writes, deploys, and maintains the function for you. For example:
Common use cases:
  • AI-powered features, such as AI summaries or AI chatbots, using built-in Lovable AI
  • Sending emails or push notifications
  • Payment processing, for example with Stripe
  • Heavy computations or external API calls
Edge functions read API keys and credentials from your project’s secrets, so sensitive values never appear in code. For recurring work on a schedule, see Jobs.

​
Monitor your functions

Go to Cloud tab → Edge functions to see every function in your project, with its status, invocation count, success rate, and when it was last updated. The time range selector has two modes: Relative covers ranges from the last 15 minutes up to the last 5 days, and Absolute lets you pick an exact start and end time. Click a function to see how it performed over time:
  • Succeeded and Failed invocation counts with a chart over the selected range.
  • Copy URL to copy the function’s endpoint.
  • View logs to open Logs pre-filtered to this function’s output.
  • View code to open the function’s source in the code editor.
If a function fails, Lovable surfaces the error so you can ask it to fix the problem in chat.

FAQ

Ask Lovable in chat. There is no create button in the Edge functions view: Lovable writes and deploys functions as part of building the feature you describe. To change one, describe the new behavior, or open its code with View code.
No. Edge functions are unavailable while a project is paused, so features that depend on them stop working until you resume the project. See Pause Cloud.
Open the function and click View logs, which opens the Logs view filtered to that function. Each failed invocation includes the error output. You can also paste the error into chat and ask Lovable to fix it.
