Serverless functions for fast and critical services for Node.js
Fleet is a Function as a Service technology that solves problems known as cold starting, allows you to build fast services that are critical in response time.
Functions over VM
Each function per VM
Functions over Isolates
Hundreds of isolated functions per process
How it works
Fleet Function is a serverless function technology, which automatically scales its functions to 0 and N according to the number of requests that your function receives, runs in an isolated environment in Node.js that eliminates cold starting, you can control the asynchronous limit of function to adjust the rate that a function can handle requests at a time as well as the concurrency limit.
V8 Isolates
Node.js uses the V8 engine under the hood to interpret and execute JavaScript code. V8 has a concept of isolates that allows JavaScript code to run safely in browsers.
Use Isolates to perform functions
Fleet uses isolates to perform thousands of functions in a single but safe process with isolated memory.
Invoke functions fastest
Fleet can provision functions much more quickly almost eliminating cold starts and isolates have less memory consumption.

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.
Read the docs
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.
Get started
export default async (req, res) => {const user = await User.get(req.query.userId);
return res.send(user);}
