Built on OpenWhisk
Apache OpenWhisk is an open-source serverless platform enabling event-driven applications with minimal infrastructure management.
What Makes evrtng Functions Powerful
Event-Driven Architecture
Execute code in response to HTTP requests, MQTT messages, database changes, and custom triggers via rule-linked actions.
Web Actions
Serve dynamic or static web content directly through REST APIs. Return HTML, JSON, images, cookies, or custom headers.
Action Sequences
Chain multiple actions into workflows. Built-in utilities like split and sort simplify data processing pipelines.
Polyglot Runtimes
Write functions in JS, Python, Java, Go, PHP, Ruby, Swift, .NET, Scala, Rust, and Docker-based custom runtimes.
Integrated Tooling
Deploy, log, and monitor with the wsk CLI. Integrate with GitHub Actions, Jenkins, or any CI/CD pipeline.
Enterprise Scalability
Supports thousands of concurrent executions with per-request scaling. Pay nothing when idle.
Namespace Isolation
Your functions run in isolated namespaces. Secure, sandboxed execution per tenant.
Triggers & Rules
Create event sources and link them to actions via rules. Decouple events from logic for flexible architecture.
Activation Logs
Every invocation is recorded. Query logs, check durations, and debug with wsk activation list.
What Can You Build?
IoT & Sensor Data
Process MQTT sensor events in real-time. Update dashboards, trigger alerts, and write to databases automatically.
API Backends
Build fast, scalable REST APIs for web and mobile apps without managing a single server.
Workflow Automation
Chain actions into sequences for ETL pipelines, data transformations, and cross-service integrations.
Image Processing
Resize, annotate, or transform images on upload. Trigger from storage events or HTTP.
Scheduled Tasks
Cron-based triggers run periodic jobs — reports, cleanups, notifications — on your schedule.
Legacy Modernization
Wrap legacy systems in serverless APIs. Migrate piece-by-piece without big-bang rewrites.
