Open source and open standards
Weik.io is open source under the Apache License 2.0, and it uses open standards where your integrations meet other systems: Apache Camel for integrations, CloudEvents for events, OpenAPI for APIs, OpenID Connect for sign-in and OpenTelemetry for logs, metrics and traces.

| OpenAPI | The platform's HTTP API is described in OpenAPI, and integrations call other APIs from their OpenAPI documents with Camel's rest-openapi component |
| OpenTelemetry and OTLP | Logs, metrics and traces from every integration, and forwarding to your own systems |
| OpenID Connect and OAuth 2.0 | Sign-in with Microsoft Entra ID or any OpenID Connect provider, API subscriptions with tokens, and upstream authentication |
| The S3 API | Backup copies, and sources and destinations of file transfers |
| SFTP and FTP | Sources and destinations of file transfers |
| The Prometheus text format | The metrics of every process of the platform |
| JSON Schema | A schema for every YAML document kind, for validation in your editor |
Open source inside every image
Every image contains /LICENSE, /NOTICE and /THIRD-PARTY-NOTICES.txt. The third-party notices list every third-party component in the image, with its licence and the licence and notice files the component ships. The licence of everything in a release is checked before the release is published.
Third-party software in 2026.2 lists the open source projects inside the images with their versions and licences.
