Dakia: The Developer-Centric API Gateway

Dakia is an advanced API Gateway designed with developers in mind, offering a fully configurable, extensible and programmable solution. With Dakia, developers are treated as first-class citizens, enabling them to customize and tailor the gateway to fit the unique needs...

Feature highlights

• Configurable: Easily manage API configurations using various formats like YAML, JSON, and HTTP API calls.
• Extensible: Add new functionality with support for custom middleware and plugins, written in any programming language (Rust, Java, C++, etc.).
• Fully Programmable: Tailor the API Gateway to your specific needs with custom plugins and middleware in multiple languages.
• Zero Downtime Upgrades: Perform upgrades and restarts without affecting the availability of your services.
• Dynamic Middleware: Add, remove, or modify middleware on the fly without disrupting service.
• Request and Response Management: Modify requests before they reach the upstream or read/write responses to meet your application's needs.
• Real-Time Configuration: Modify your gateway configuration in real time with no downtime, using HTTP API calls.

Dakia ensures your services stay performant, reliable, and highly customizable, giving you full control.

Limitations ☠️

These limitations will be addressed over time as we continue to improve the dakia.

• Currently supports only UTF-8 character encoding.
• Only the round-robin load balancing algorithm is available at the moment.
• IPv6 addresses are not supported at this time; only IPv4 is supported.
• Currently it supports only HTTP protocol

Reasons to use Dakia

• Security - Built with Rust, Dakia ensures enhanced memory safety and reduces vulnerabilities compared to services written in C/C++.
• Performance - Powered by pingora, a battle tested protocol implemention, as it has been serving more than 40M+ internet requests per second for more than a few years.
• Customization - You need ultimate customization, you can configure, extend and even further program in multiple languages.
• Asynchronous and Multi-Threaded – Dakia is designed to handle tasks concurrently, ensuring efficient and high-performance request processing by default.
