With today’s release of OpenCelium 4.6, we are not only celebrating an important milestone in product development—we are also commemorating a special date: the birthday of our company founder Hans-Otto Brunsch († 2013).
He founded becon GmbH, which became the independent OpenCelium GmbH in 2023. The release therefore represents not only technical advancement, but also the continuation of a vision: to make integration simple, transparent, and efficient.
The OpenCelium 4.6 release is now available for download and includes three major features as well as numerous bug fixes that significantly simplify working with interfaces:
- UI logs for Connection Editor & Scheduler
- Multi-language support for enhancements
- Smart Sync – Templates & Invoker from the Service Portal
Below, we present all the new features and benefits in detail.
Overview of new features – OpenCelium 4.6 release
UI logs for Connection Editor & Scheduler
The new UI logs make developing, debugging, and monitoring interfaces significantly easier and visually clearer.
Developers now receive direct log feedback in the Connection Editor and can analyze API requests in a clearly structured layout.
Important changes:
- Direct log feedback: Results can be checked immediately in the UI—without any detours.
- Structured log design: Each API request can be collapsed, loops are displayed compactly and can be expanded if necessary.
- Paginator navigation: Facilitates targeted analysis of individual requests.
- Optimized for large amounts of data: Even complex interfaces can be displayed with high performance.
- Live data via WebSocket: Logs are streamed in real time – perfect for monitoring and debugging.
- Uniform concept: The new log design also applies to scheduler jobs (historical & current).
Advantages at a glance:
Greater transparency and improved usability in interface development
Uniform logging across testing, development, and execution
Live analysis and traceability of past processes
Modern technology through WebSocket integration
Multi-language support for enhancements
Another highlight of the OpenCelium 4.6 release is the new multi-language support for enhancements.
In addition to JavaScript, Python 2, Python 3, and Ruby are now also supported—other languages such as Go and TypeScript are already in the pipeline.
What is behind this?
OpenCelium uses so-called references to reuse data from an API response in the next request.
These values can be manipulated using enhancements before they are transferred—e.g., through formatting or logical adjustments.
With the new multi-language feature, developers can now implement this logic in their preferred language.
A dedicated microservice ensures secure, encapsulated, and high-performance code execution outside the core, while JavaScript is processed directly in the core as usual.
Advantages:
Greater flexibility through support for multiple programming languages
Integration of existing code snippets in different languages
Secure code execution thanks to decoupling from the core system
Future-proof design thanks to modular microservices
Example:
Instead of working only with JavaScript as before, Python or Ruby can now also be used. This extension makes OpenCelium even more powerful in the implementation of integration logic – without any programming.
JavaScript
let result = VAR_0.toUpperCase();
RESULT_VAR = result;
Python
result = VAR_0.upper()
RESULT_VAR = result
Ruby
result = VAR_0.upcase
RESULT_VAR = result
Smart Sync – Templates & Invoker from the Service Portal
The Smart Sync feature establishes a direct connection between the OpenCelium Service Portal and a local instance for the first time.
This allows templates and invokers to be synchronized automatically—without any manual downloads or file uploads.
The OpenCelium Service Portal is an exclusive SaaS service for subscription users with access to:
- Pre-built templates and invokers
- Information on product innovations
- Integrated ticket system for support & feedback
- Download area for current versions
What’s new?
- Direct portal connection: After one-time authentication, synchronization occurs automatically.
- Automatic & manual sync option: Time-controlled or manually via button in the interface.
- Version control & conflict handling: Checks local adjustments before content is overwritten.
- Seamless integration into the UI: New or updated content is available immediately.
Advantages:
Significantly less effort required to maintain integration content
Always have access to the latest templates and invokers
Elimination of error-prone manual file transfers
Ideal for teams with multiple instances or CI/CD setups
Outlook:
The Smart Sync feature forms the basis for further portal integrations, such as:
- Push your own invokers/templates to private spaces
- Direct link to the ticket system
- Automatic system monitoring and proactive support
Conclusion on the OpenCelium 4.6 release
With the release of OpenCelium 4.6, we are consistently focusing on usability, flexibility, and integration strength.
The three new features—UI logs, multilingual support, and Smart Sync—bring measurable improvements to daily operations and make OpenCelium even more transparent, efficient, and modern.
