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.

Managed & maintained for you

Convenience isn't enough when it comes to handling custom domains in production - everything needs to be rock solid and reliable.

Approximated has constant monitoring, globally distributed servers, and automatically self-healing clusters so that it's ultra reliable.

Sophisticated monitoring at every level

Approximated is always monitoring the SSL status, DNS resolution, proxy hit status, and more for every domain. No external monitoring or infrastucture required - Approximated includes this for free.

Self-healing clusters with intelligent routing

Frequent health checks for every region of your cluster allow Approximated to find and heal any potentials issues before you or your users run into them. Traffic is automatically be routed to the nearest working region during any repairs to avoid any downtime.

Flask features and specs

  • Simplicity
    Flask is a micro-framework, meaning it is lightweight, easy to understand, and simple to use. It requires minimal setup to get a web application up and running.
  • Flexibility
    Flask provides flexibility and control over the application's architecture, allowing developers to choose the components they need and avoid unnecessary bloat.
  • Extensibility
    Flask supports various extensions to add capabilities like database integration, form validation, and authentication without compromising its core simplicity.
  • Documentation
    Flask has comprehensive and well-organized documentation, making it easier for developers to learn and implement features effectively.

Possible disadvantages of Flask

  • Scalability
    Flask may not be as scalable as some other frameworks for very large applications due to its minimalist design and lack of built-in features.
  • Boilerplate Code
    Since Flask requires you to integrate and configure many components manually, codebases in Flask can sometimes contain a lot of boilerplate code.
  • Opinionated Architecture
    While Flask provides flexibility, it also means there are fewer conventions. Developers must make more architectural decisions, which can be challenging for large team collaboration.
  • Limited Tools
    Compared to more comprehensive frameworks, Flask offers fewer built-in tools and features, which may necessitate additional plugins or custom implementations.
  • Learning Curve for Complex Applications
    While Flask is easy to learn for simple applications, it can become complex to manage as the application grows, requiring a good understanding of design patterns and software architecture.
