Compute
8
Workers
The kitchen behind every app. When someone visits a website, submits a form, or makes a request, a Worker handles it instantly from 300+ cities worldwide. No servers to buy or manage. This is the engine everything else on the platform runs on.
Docs ↗
Pages
A website publishing machine. Developers connect their code, and every time they update it, the website goes live automatically. The fastest path from 'code written' to 'website online' on Cloudflare.
Docs ↗
Durable Objects
A reserved table at a restaurant. Most compute handles a request and moves on. Durable Objects stick around and remember who's at the table. This is what powers chat rooms, multiplayer games, and collaborative editing — anything where multiple people interact in real time.
Docs ↗
Queues
A deli counter with a 'now serving' display. Jobs line up, get processed one at a time, never lost. Send a confirmation email, resize a photo, update a record — the work happens in the background so the customer isn't left waiting.
Docs ↗
Workflows
An assembly line with a clipboard. Multi-step jobs that run in order. If step 3 fails at 2am, it picks up from step 3 in the morning — not step 1.
Docs ↗
Containers
A shipping container for software. Some applications are too big or complex for Workers — maybe they were built years ago, or they need heavy computing power. Containers let you run those on Cloudflare's network without rebuilding them from scratch.
Docs ↗
Dynamic Workers
Temporary pop-up kitchens. Spin up throwaway Workers on the fly — perfect when your platform needs to run your customers' code safely without it affecting anyone else. Each one is completely walled off, then torn down when done.
Docs ↗
Workers Builds
The factory floor. Every time a developer pushes an update, Cloudflare builds and packages the code before it goes live. Six thousand build minutes included on paid plans. The assembly step between 'code written' and 'code running.'
Docs ↗
Storage
9
KV
A dictionary. Look up a word (the key), get the definition (the value). Reads are near-instant from anywhere in the world. Great for storing settings, preferences, or any small piece of data you need to look up fast.
Docs ↗
R2
A storage unit. Throw files in, pull them out — images, documents, backups, datasets. Unlike most cloud storage, you don't pay extra when someone downloads your files. Data goes in, data comes out, no surprise retrieval charges.
Docs ↗
R2 Data Catalog
A filing cabinet with an index card system. Takes a pile of files sitting in R2 and organizes them into structured, searchable tables. Instead of digging through thousands of files by hand, you can ask questions about the data directly.
Docs ↗
R2 SQL
A search engine for your storage unit. Ask questions about data sitting in R2 using a query language — 'show me all files uploaded last month over 1GB.' No need to move the data somewhere else first.
Docs ↗
D1
A spreadsheet with superpowers. A real database that lives on Cloudflare's network. User profiles, product catalogs, order histories — structured data with rows and columns that you can search and filter instantly.
Docs ↗
Hyperdrive
A carpool lane to your existing database. Most companies already have a database somewhere. Hyperdrive makes the connection between that database and Cloudflare dramatically faster. You keep what you have, it just runs quicker.
Docs ↗
Vectorize
A librarian who understands meaning, not just keywords. Instead of searching by exact words, Vectorize lets AI applications find things by concept — 'show me articles similar to this one' or 'find products that look like this.' It powers the smart search behind AI features.
Docs ↗
Pipelines
A conveyor belt. Data flows in continuously — clicks, logs, events — and gets automatically sorted into neat batches in storage. Instead of managing the firehose yourself, Pipelines collects and organizes it for you.
Docs ↗
Cache Reserve
A reserved parking spot for popular content. Normally, Cloudflare might clear less-visited content from its cache to make room for busier stuff. Cache Reserve guarantees your content stays cached and loads fast, even during quiet periods. Same pricing as R2 storage.
Docs ↗
Observability
3
Workers Logs
A security camera for your application. Every time it handles a request, it can record what happened — who asked, what was sent back, how long it took. Twenty million entries included per month on paid plans. The first place developers look when something goes wrong.
Docs ↗
Workers Tracing
A package tracker for requests. When a customer's request passes through multiple parts of the system, Tracing shows every stop along the way and how long each one took. The X-ray that shows exactly where a slowdown happened.
Docs ↗
Analytics Engine
A tally counter. Track millions of events per second — page views, button clicks, response times — then ask questions about the numbers later. Built for counting and measuring at massive scale, not for storing customer records.
Docs ↗
AI
6
Workers AI
A rented brain. Run AI models — generate text, analyze images, translate languages — without buying expensive hardware. Pay per use. The AI runs on Cloudflare's machines; your app just sends a request and gets an answer back.
Docs ↗
AI Gateway
A tollbooth for AI traffic. Sits between your app and any AI provider (OpenAI, Anthropic, Google, etc.). Tracks spending, prevents abuse, saves money by reusing repeated answers, and logs everything. One dashboard to manage all your AI costs.
Docs ↗
Agents SDK
A blueprint for building AI assistants. Gives developers the tools to create AI agents that can take real actions on their own — book a flight, answer customer questions, process orders — not just chat back and forth.
Docs ↗
Agent Memory
A notebook your AI agent carries between conversations. Automatically extracts and recalls facts so your agent remembers users, decisions, and context over time.
Docs ↗
AI Search
A research assistant on standby. Point it at your company's documents, and it reads, organizes, and indexes everything automatically. Then anyone can ask plain-English questions and get answers pulled straight from your own data. No AI expertise needed to set it up.
Docs ↗
Browser Run
A robot with a web browser. Opens real web pages in the cloud — takes screenshots, reads content, fills out forms, generates PDFs. The same way you'd browse the web, but automated and at scale. This is how AI agents interact with websites.
Docs ↗
Media
4
Images
A photo lab. Upload one image, and Cloudflare serves the perfect version for every screen automatically. Phone gets a small file, desktop gets a large one, and the format is always optimized for speed. One image stored, infinite versions delivered.
Docs ↗
Stream
A TV station. Upload a video, get a player you can embed anywhere. Cloudflare handles everything — making it play smoothly on fast and slow connections, storing it, delivering it worldwide. Upload, embed, done.
Docs ↗
RealtimeKit
A video call studio. Tools for building live audio and video directly into any app — video meetings, webinars, live streaming. Low delay, scales to thousands of participants automatically.
Docs ↗
Media Transformations
A photo editor built into the URL. Resize, crop, or reformat any image just by changing the web address — no design software, no pre-processing. The image adapts on the fly based on what you ask for.
Docs ↗
Email
2
Email Routing
A mail room. Emails arrive at your custom domain (
[email protected]
) and get forwarded wherever you want — personal Gmail, work inbox, or into an automated workflow. Free to use.
Docs ↗
Email Service
A stamped envelope. Send emails directly from your application — order confirmations, password resets, alerts, welcome messages. No third-party email service needed. Built right into Cloudflare, billed per email sent.
Docs ↗
Security
3
Turnstile
A bouncer who doesn't ask questions. Replaces those annoying 'click all the traffic lights' puzzles. Verifies visitors are human invisibly — bots get blocked, real people don't even notice it's there.
Docs ↗
Flagship
A light switch for features. Release something new to 10% of users first, see how it goes, then roll it out to everyone — or turn it off instantly if something breaks. No new software release needed. Control who sees what, in real time.
Docs ↗
Secrets Store
A safe. Passwords, secret keys, and credentials your application needs — locked up, encrypted, and only handed over when needed. Keeps sensitive information out of the code and behind a locked door.
Docs ↗
Networking
3
Workers VPC
A private tunnel to your cloud. Connects Cloudflare directly to your company's private networks in AWS, Google Cloud, or Azure — no data ever touches the public internet. Your applications can reach internal systems as if they were in the same building.
Docs ↗
Workers for Platforms
A landlord's toolkit. If you run a platform where your customers need to add their own custom logic — think Shopify apps or plugin systems — this lets each customer run their own code safely on your infrastructure. Everyone is isolated from each other.
Docs ↗
Cloudflare Wallets
A name tag for payments. A human-readable handle (like a username) that gives your apps and AI agents a stable identity for making and receiving payments. The payment address for the AI-powered web.
Docs ↗
Dev Tools
4
Wrangler
The developer's toolbelt. The command-line tool that does everything — create projects, test locally, publish live, manage secrets. If a developer is building on Cloudflare, they're using Wrangler.
Docs ↗
Sandbox SDK
A padded room for code. Lets your platform safely run code submitted by users or outside parties. Each piece runs in its own isolated bubble with strict limits — it can't touch anything it shouldn't. A controlled test chamber.
Docs ↗
Artifacts
A locker for build outputs. When applications create files during the build process — compiled code, generated assets, configuration — Artifacts stores and versions them so they're always retrievable. A filing system for everything your code produces.
Docs ↗
Terraform / Pulumi
A blueprint for your infrastructure. Instead of clicking through a dashboard to set things up, you define everything in a file. That file can be versioned, reviewed, and reused to recreate the exact same setup anywhere. Infrastructure as a recipe.
