Best Function as a Service (FaaS) Providers

Run code without thinking about servers. Pay only for the compute time you consume. AWS Lambda lets you run code without provisioning or managing servers. You pay only for the compute time you consume. With Lambda, you can run code for virtually any type of application or backend service - all with zero administration. Just upload your code and Lambda takes care of everything required to run and scale your code with high availability. You can set up your code to automatically trigger from other AWS services or call it directly from any web or mobile app. AWS Lambda automatically runs your code without requiring you to provision or manage servers. Just write the code and upload it to Lambda. AWS Lambda automatically scales your application by running code in response to each trigger. Your code runs in parallel and processes each trigger individually, scaling precisely with the size of the workload.

While Cloud Run is primarily a CaaS platform, it also offers functionality similar to Function as a Service (FaaS), allowing developers to deploy single functions in containers and have them run in response to HTTP requests. This serverless model means that developers only pay for the actual compute time their functions use, without worrying about managing servers or infrastructure. Cloud Run automatically handles scaling, ensuring that functions are spun up and down based on demand, allowing for efficient resource allocation. The $300 in free credits provided to new customers is an excellent opportunity to experiment with Cloud Run’s FaaS capabilities, helping developers understand how it can simplify their application architecture. Cloud Run’s flexibility in supporting both containerized applications and serverless functions makes it a versatile tool for building scalable solutions. Whether for microservices or serverless functions, Cloud Run offers a unified environment.

We run physical servers in cities close to your users. As close to the metal as you can get without paying shipping. We run physical servers in cities close to your users. As close to the metal as you can get without paying shipping. Provision exactly what you need to make your apps fly. Pay only for what you use. The plumbing you need to sleep at night. Pretty graphs for morning coffee. Zero configuration private networking and global load balancing. Add certificates for your own purposes, or a million for your customers. We'll be using the standard web application generated by Remix. This is a bare-bones app with no database. If you're feeling ambitious, check out the Remix tutorial for building and deploying an SQLite-backed app on Fly.io.

You write code. We handle the rest. Deploy serverless code instantly across the globe to give it exceptional performance, reliability, and scale. No more configuring auto-scaling, load balancers, or paying for capacity you don’t use. Traffic is automatically routed and load balanced across thousands of servers. Sleep well as your code scales effortlessly. Every deploy is made to a network of data centers running V8 isolates. Your code is powered by Cloudflare’s network which is milliseconds away from virtually every Internet user. Choose from a template in your language to kickstart building an app, creating a function, or writing an API. We have templates, tutorials, and a CLI to get you up and running in no time. Most serverless platforms experience a cold start every time you deploy or your service increases in popularity. Workers can run your code instantly, without cold starts. The first 100,000 requests each day are free and paid plans start at just $5/10 million requests.

End-to-end development experience with integrated tools and built-in DevOps capabilities. Integrated programming model to respond to events and seamlessly connect to other services. Implement a variety of functions and scenarios, such as web apps and APIs with .NET, Node.js, or Java; machine learning workflows with Python; and cloud automation with PowerShell. Get a complete serverless application development experience—from building and debugging locally to deploying and monitoring in the cloud.

Google Cloud Functions has a simple and intuitive developer experience. Just write your code and let Google Cloud handle the operational infrastructure. Develop faster by writing and running small code snippets that respond to events. Connect to Google Cloud or third-party cloud services via triggers to streamline challenging orchestration problems.

Serverless functions, made simple. OpenFaaS® makes it simple to deploy both functions and existing code to Kubernetes. Avoid lock-in through the use of Docker. Run-on any public or private cloud. Build both microservices & functions in any language. Legacy code and binaries. Auto-scale for demand or to zero when idle. Bring your laptop, your own on-prem hardware, or create a cluster in the cloud. Let Kubernetes do the heavy lifting enabling you to build a scalable, fault-tolerant event-driven serverless platform for your applications. You can try out OpenFaaS in 60 seconds or write and deploy your first Python function in around 10-15 minutes. From there you can take the OpenFaaS workshop, a series of tried-and-tested self-paced labs which teach you everything you need to know about functions, and more. An ecosystem for sharing, reusing, and collaborating on functions. Reduce boilerplate code, and share code in the templates store.

Write your backend like a Flutter app, and deploy it like magic. Celest is a cloud platform tailored for Flutter developers, enabling them to build, deploy, and manage backends entirely in Dart. By annotating any Dart function with the cloud, developers can transform it into a serverless function, streamlining backend logic within the Flutter ecosystem. Celest seamlessly integrates with Drift schemas, automatically generating databases to simplify data management. Deployment is efficient, requiring just a single command. This process initializes Celest, migrates the project, warms up the engines, and deploys to Celest cloud, culminating in a live project URL. The platform supports features like Dart cloud functions, Flutter on the server, server-side widgets (coming soon), hot reload, auto-serialization, and client generation. Celest is designed to enhance the development experience for Flutter developers.
