A Serverless Framework plugin that eliminates AWS Lambda cold starts by creating scheduled warmer functions. The warmer invokes your selected lambdas at a configured interval (default 5 minutes) to keep their containers warm.

Use cases

• prevent lambda cold starts on aws
• keep serverless functions warm during business hours
• schedule periodic lambda invocations
• reduce latency spikes in serverless apis
• configure concurrency warming for lambda functions
• avoid cold start penalties for low-traffic endpoints

When to choose

• you use the Serverless Framework with AWS provider and suffer from cold starts
• you need fine-grained warming schedules like office-hours-only warming
• you want per-function control over which lambdas get warmed and with what concurrency

When to avoid

• you use a provider other than AWS or don't use the Serverless Framework
• your functions are invoked frequently enough that cold starts are not an issue
• you prefer provisioned concurrency or other native AWS solutions
