What is evrtng Functions?

evrtng Functions is a serverless function runtime on evrtng.cloud: deploy your code, get an HTTPS endpoint instantly, pay per invocation.

Is there a free plan?

Yes — a free plan with 1,000 invocations per day, 128 MB memory and 5s timeout. No credit card required.

How much does evrtng Functions cost?

Starter costs EUR 9.99/month (10,000 invocations/day), Pro EUR 49.99/month (100,000 invocations/day). Overage is billed per call.

Platform

Built on Fission + Firecracker

Fission is an open-source serverless platform (Apache-2.0, Kubernetes-native). Every function runs in its own Firecracker micro-VM — isolated, fast to start, billed per invocation.

Core Features

What Makes evrtng Functions Powerful

Event-Driven Architecture

HTTP triggers for every function, cron triggers for scheduled work, Kafka triggers on request. Events and logic stay decoupled.

Tenant URLs Built In

Every account gets its own URL space — https://your-namespace.fnc4.evrtng.cloud — with TLS, rate limiting, and per-invocation billing. No API gateway required.

Custom Docker Images

Reference your own runtime image (publicly pullable, Fission environment protocol) and deploy any language or framework.

Polyglot Runtimes

Python, Node.js, Go, PHP, Ruby, JVM/Java, and Binary (Docker image) — all verified and production-ready.

REST Management API

Manage functions, triggers, and environments with curl and your API key — straight from GitHub Actions, Jenkins, or any CI/CD pipeline.

Scales Per Invocation

Up to 50 (Pro) or 200 (Enterprise) concurrent executions per plan. Idle costs nothing — you pay per invocation.

Firecracker Isolation

Every function runs in its own Firecracker micro-VM — no shared kernel, no neighbours in your memory. Hardened isolation no hyperscaler offers at this price.

Zero to Production

Create a function and give it a URL in two API calls. Existing runtimes answer in ~0.15s from warm pools.

Activation Logs

Every invocation is recorded: duration, status, response via the activations endpoint. Management actions appear in the audit trail.

Use Cases

What Can You Build?

IoT & Sensor Data

Process Kafka event streams 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

ETL pipelines, data transformations, and cross-service integrations with trigger chains and event-driven functions.

Image Processing

Resize, annotate, or transform images on upload — triggered via HTTP or Kafka.

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.
