Yes, AWS Lambda has a permanent free tier alongside its paid plans. The free plan includes 400,000 GB-seconds of compute time per month for x86 and Graviton2 functions, in aggregate. FreeTier.co estimates the free tier at about $6.87/mo.
About
AWS Lambda is a serverless compute service that runs code without requiring server provisioning or cluster management. It is designed to help teams build event-driven applications, backends, and automation workflows with minimal infrastructure overhead.
The service supports a broad range of use cases, including web and mobile backends, batch and real-time data processing, generative AI workflows, and other event-driven workloads. It integrates with AWS services and external event sources so teams can focus on application logic rather than operational maintenance.
- Run code in response to events without managing servers.
- Scale automatically with workload demand.
- Support web, mobile, data, and AI-driven serverless applications.
- Integrate with AWS services and third-party event sources.
Free Tier Value
This free tier is worth about $6.87/month at AWS’s published Lambda rates: 1 million requests at $0.20 per million is about $0.20, and 400,000 GB-seconds at roughly $0.0000166667 per GB-second is about $6.67. It renews every month and includes the standard 512 MB of ephemeral storage at no extra cost, but a credit card is still required to create the account, so the value is strong while the signup friction remains.
