How it works

The ultimate Serverless Function

Fleet Function runs serverless functions in a secure Node.js runtime to avoid cold start issues and accept multiple requests on the same instance. Teams can easily scale their APIs based on concurrency and asynchronous limits, lowering per-request costs.

Deployment

Make a deployment to the stage dev, a URL will be created automatically.

Promote Production

Confidently promote stage deployment to production using rules like canary deployment.

Request fastest

Request functions via HTTP and running with near-zero cold starts, built on top of Node.js and secure.

Large Scale

Functions run as a Node.js environment, scaled asynchronously and concurrently.

Zero server
Don't worry about keeping a 24/7 server online.
Auto-Scale
Its functions are invoked to 0 and N.
Pay for use
Costs are made based on the resources you use.
Simplify DevOps
There is no need to configure infrastructure or handle containers.

Designed for developers

Easy-to-use and ecosystem-friendly APIs

We spend time and suffering from the right abstractions so your teams don't have to spend time dealing with infrastructure or spend months setting up the APIs environment and infrastructure.

Simply easy to create APIs

The creation of APIs is similar to how you create routes using express.js or fastify.js.

See examples

Easy to start

Quickly build APIs in a matter of seconds and you can use them production-ready globally.

Why Fleet

Platform end-to-end

Serverless function technology from end to end with the platform for deployments, metrics, workflow...

Metrics built in
Track usage, performance and errors on your functions.
Secrets
Add sensitive environment variables that are only available for your functions.
Team
Organize your team by projects to simplify workflows and permissions.

Preview deployments

For each new deployment a new URL is assigned to your deployment for preview use.

Continuous Deployment
Build your own deployment workflow using GitHub Actions to deploy to Fleet.
Deployment history
With each new deployment, a url is created that can be used to share with your team or serve as a test endpoint.
Quick Rollbacks
Quickly rollback deployments with code failures with immediate effect in production.

Fleet Traffic Shifting

Critical microservices and APIs that meet a large scale of user demand is critical and cannot fail due to bugs in the code. The main adoption of mitigation is canary deployments.

Automation rules
Automate your canary implantations based on traffic data to decrease monitoring and mitigate errors from expensive deployments.
Manual traffic control
Perform manual traffic control as you get more data.
Monitoring
Monitor traffic to make the best decisions and adjust the rules to your reality.
