Custom plugins

Custom plugins are modular software components that inject proprietary logic, security protocols, and data transformations directly into existing application runtimes or API gateways.

When off-the-shelf software hits its functional limits, custom plugins bridge the gap by executing tailored code directly inside your primary runtime environment. By leveraging dedicated plugin APIs (such as Kong's Go and Lua SDKs or Figma's JavaScript interface), developers can intercept live traffic, modify payload structures, or automate repetitive design tasks without modifying the core application codebase. This decoupled architecture keeps your primary systems lightweight, isolates security vulnerabilities, and allows engineering teams to deploy targeted updates rapidly without risking global system downtime.
