Booster Cloud Documentation

Booster Cloud is a per-request edge platform for SaaS applications. The docs cover everything from your first snippet drop-in to running custom WAF rules and edge KV-backed feature flags at scale.

What Booster Cloud does

Three things:

Accelerates your application across 38 global edge PoPs, with intelligent caching, smart prefetch, and automatic Core Web Vitals tuning.
Observes real-user performance through a privacy-first RUM beacon — no cookies, no third-party scripts, no PII.
Protects your origin with a managed WAF, custom rules in our DSL, and DDoS scrubbing at every edge node.

The 90-second drop-in

Three steps cover the vast majority of integrations:

# 1. Add the runtime snippet to your <head>
<script src="https://r.boosterapp.io/v2/r.js" defer></script>

# 2. Point your CNAME at our anycast edge
$ dig CNAME app.example.com
app.example.com.   300   IN   CNAME   ext.boosterapp.io.

# 3. Hit the dashboard or API to enable image rewriting
$ curl -X PATCH https://api.thebooster.tech/v2/hosts/app.example.com \
    -H "Authorization: Bearer $BOOSTER_TOKEN" \
    -d '{"image_rewriting": true, "prefetch": true}'

That's it. Within a few seconds, end users start hitting the closest edge node, RUM beacons start flowing, and your dashboard lights up with Core Web Vitals numbers.

Quick paths

I'm a frontend engineer

Drop in the snippet, enable image rewriting, watch LCP drop in real time.

Quickstart →

I'm a platform engineer

Bring your own DNS, set up multi-origin routing, run custom WAF rules with version control.

Custom WAF →

I'm a developer

OAuth, signed webhooks, edge KV store, sandbox environment, full OpenAPI spec.

Authentication →

I run SRE / incident response

Synthetic checks, paged alerts, log forwarding, audit log retention, incident archive integration.

SDKs & tooling

Official clients for Node/TypeScript, Python, Go, and Rust. A Terraform provider for managing hosts, rules, and KV namespaces declaratively. A GitHub Action for synthetic Lighthouse gating in CI. Community SDKs exist for Ruby, PHP, and Java; they share the same OpenAPI surface.

Edge network

38 PoPs across North America, EU, Asia-Pacific, LATAM, and Africa. Median routing latency from a tier-1 ISP in any major metro: sub-15ms p95. The live network map with capacity per PoP: /docs/network.

What's not included

We're a focused edge accelerator. We are not:

A serverless functions platform — for that, pair us with Cloudflare Workers, Vercel, or your own runtime.
A database — see edge KV for small key-value workloads, otherwise bring your own.
A DNS provider — we plug into your existing DNS via CNAME. We do not currently sell authoritative DNS.
A video/streaming platform — we cache static MP4 and HLS playlists fine, but we are not Mux.

Getting help

The fastest path is the quickstart; it covers 80% of integrations.
Pro and Scale customers get in-app chat support with a 4-hour SLA (15-minute on Scale).
API questions: dev@thebooster.tech with a request ID. We always grep the logs.
