## What it is
Blueboat is an all-in-one, multi-tenant serverless JavaScript runtime written in Rust, designed for frictionless horizontal scalability. It provides a Web API-compatible environment (fetch, Request, Response) where local resources like files and sockets are replaced with distributed-system equivalents such as key-value stores and event streams.

## Use cases
- run serverless javascript functions on my own infrastructure
- self-host a cloudflare workers alternative
- deploy multi-tenant web apps with a javascript runtime
- build http apis with fetch and router apis
- replace local files and databases with a distributed kv store
- run typescript web services in a sandboxed runtime

## When to choose
- you want a Cloudflare Workers-like runtime you can self-host
- you need multi-tenant isolation and horizontal scalability over single-node performance
- you prefer Web API compatibility (fetch, Request, Response) in a serverless environment
- you want built-in KV storage, MySQL/PostgreSQL access, and WebSocket support in one runtime

## When to avoid
- you need Node.js compatibility or npm native modules
- your app depends on local filesystem, raw sockets, or FFI
- you need a mature, actively released production runtime - the latest release dates to early 2023
- you want single-node performance optimization rather than distributed-system abstractions
