Easy to setup,
simple to automate

Approximated treats convenience and simplicity as a first class citizen, going the extra mile to make every step as easy as possible to integrate.

How it works

Approximated creates a dedicated cluster just for you, with edge servers in regions all over the world. These proxy traffic for custom domains to your app at any scale with incredibly low latency.

1. Create your dedicated cluster

Approximated spins up a dedicated cluster, with nodes distributed globally. Traffic is automatically routed through the region nearest users for lightning fast response times. All you need to do is name it.

2. Call the API, or use the dashboard

Connecting a custom domain takes one API call to Approximated. Or, use the dashboard to do the same thing any time. The dashboard will even show you what that would look like as an API call.

3. Point the domain(s)

All that's needed is one DNS A record pointed at your cluster's dedicated IP address. Approximated will automatically create and manage SSL certificates for every domain.

Reliability as a feature

Approximated treats reliability as a core feature, because uptime matters. Get powerful monitoring, self-healing systems, and expert support from developers.

“Approximated is an integral part of our infrastructure and is helping us manage a ton of traffic on a daily basis. The technology is rock solid, and the API is very well documented.

We explored a few other tools before Approximated, but all were expensive and a pain to setup. We also debated building our own custom domain infrastructure until we found Approximated.

Within 15 minutes we were up and running, and our integration was ready and working in our app in just a few hours. The team has done a fantastic job and I can't recommend it enough.

If your application needs to handle custom domains with SSL, then Approximated is a must-have service in your tech stack.”

Edge Sequences

Apply rules at the edge

Approximated makes it easy to manage requests and apply rule sets at the edge with our Edge Sequences feature.

Flexible request matching with ease.
Edge Sequences can match requests by almost any combination of details. Headers, paths, geolocation, IP ranges, and so much more.
Chain Edge Rules for complex actions.
When a request matches an edge sequence, you can chain together Edge Rules in order to modify, block, or redirect requests at the edge - before or after reaching your app.
Combine Edge Sequences to power sophisticated use cases.
Requests can match multiple Edge Sequences, if you choose, which can be combined together to handle almost any use case.
Safely manage deployment with versioning.
Edge Sequences are versioned so that you and your team can safely tinker without affecting production. Deploy a new version when ready, or easily roll back to an old one any time.

Blocking bad actors at the edge

WAF & DDoS Protection

Our Web Application Firewall monitors for attacks on each cluster and works to mitigate them for everyone.

A collective immune system for your web apps.
Each cluster reports unusual traffic patterns to Approximated, which then implements mitigations as needed for all clusters. Your cluster benefits from the experience of others.
Strength in numbers
We're able to determine attacks more easily and gain an advantage on distributed attackers with each new Approximated cluster created.
Tracking and blocking bots at the edge.
Approximated keeps a living record of IPs with known bot activity, blocking them for you before they reach your app.
Zero effort protection.
There's nothing for you to setup or manage - Approximated provides all of this to all clusters out of the box.
