Logo for Architect

Declaratively define next generation cloud infra with plain text. Build database backed web apps rapidly. Execute long running background tasks (15min), queues, and scheduled jobs. All open source.

Specifically for AWS.

Logo for Azure Functions

Develop more efficiently with Functions, an event-driven serverless compute platform that can also solve complex orchestration problems. Build and debug locally without additional setup, deploy and operate at scale in the cloud, and integrate services using triggers and bindings.

Logo for Claudia

Claudia isn’t a cloud functions provider, it’s a Node.js library to help deploy Node functions to AWS Lambda.

Logo for Cloudflare Workers

Build serverless applications on Cloudflare’s global cloud network of data centers in 250 cities across 100+ countries. Cloudflare Workers provides a lightweight JavaScript execution environment that allows developers to augment existing applications or create entirely new ones without configuring or maintaining infrastructure.

Here’s a tutorial from Leonardo Losoviz .
Logo for Functional Fleet

The All-in-one Serverless Platform connected to the power of AWS Lamda. Automated scaling at one place.

Logo for Google Cloud Functions

“Event-driven serverless compute platform”. There is a web-based console to create them, or a gcloud command line tool.

Logo for HubSpot CMS Hub

Serverless functions on CMS Hub allows developers to easily build powerful web applications by deploying Node.js functions to an endpoint exposed on your website domain. The serverless functions are co-located with the rest of your developer file system and allow configuration of request methods, secrets, environmental variables and more.

Logo for AWS Lambda

The original cloud functions provider, and probably the biggest. Many other services use AWS Lambda under the hood, for example, Netlify Functions are Lambdas.

Logo for Netlify

Netlify lets you deploy Lambda functions without an AWS account, and with function management handled directly within Netlify. Your functions are version-controlled, built, and deployed along with the rest of your Netlify site, and we will automatically handle service discovery through our built-in API gateway. This eliminates overhead and brings the power of Deploy Previews and rollbacks to your functions.

Logo for Realm Functions

Realm Functions is for adding server-side logic to your app through a web interface.

Logo for Serverless Framework

Cloud functions are at the heart of building things in a serverless fashion. Serverless Framework is for helping build those. While it isn’t an infrastructure provider itself, it helps you deploy to any of the major providers, which is mighty helpful. It also has a method for running the functions locally, which is very useful for development and testing.

Logo for StackPath

Deploy and execute your serverless functions in 45+ edge locations to accelerate app performance.

Logo for StdLib
StdLib is based on Function as a Service (“server-less”) architecture, popularized by AWS Lambda. You can use StdLib to build modular, scalable APIs for yourself and other developers in minutes without having to manage servers, gateways, domains, write documentation, or build SDKs. They also offer Code.xyz , and online code editor for working with the APIs.
Logo for Vercel

Vercel (previously Zeit Now) is interesting in that a deployment through it will turn any code it finds that is appropriate into a cloud function you can run. The docs linked to here show that PHP files can be run like that, as well as Node.js, Go, Python, Rust, and Bash.
